  • Hands-on expertise with one or more of the following including ansible, puppet, docker, KMS, IAM, jenkins
  • Proficiency in a common scripting language including but not limited to Python, Ruby, etc.
  • Able to troubleshoot and debug issues, and demonstrate a methodical approach to root cause analysis
  • Strong written and verbal communication skills; attentive to details

Preferred Qualifications:

  • 6+ years implementing software
  • Ability to read and write code written in one or more of Go, Java, Scala, and C/C++
  • 3+ years implementing software in AWS
  • 1+ years using monitoring, alerting, and automation tooling
  • Previous experience in one of the three focus areas of blockchain node operations, validators as a service, and wallet infrastructure
  • Experience in a code-first environment, developing automated solutions to solve support and operational issues

This range is not inclusive of our discretionary bonus or equity package. When determining a candidate’s compensation, we consider a number of factors including skillset, experience, job scope, and current market data.

At Gemini, we strive to build diverse teams that reflect the people we want to empower through our products, and we are committed to equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity, or Veteran status.

We are looking for a Senior Fullstack Engineer with a keen interest in the development of modern web platforms, as well as the ambition for personal growth and innovation. As part of a cross-functional team, you’ll be taking a lead on some of the most important and core parts of our platform.

Requirements

About You and Job Responsibilities:

You’re pragmatic, learn quickly, and have a proven track record of experience. You communicate well and enjoy working in a startup team. Above all, you’re curious about the world and passionate about what you do. The thought of working on one of the hottest platforms that bridges the traditional financial world with the world of cryptocurrencies genuinely excites you.

As a fullstack engineer, you’re passionate about building high-quality scalable applications end-to-end. Most likely you have stronger engineering background in either frontend or backend. Yet you can still be productive in both while possessing expertise in one or more common server-side programming languages (such as Java, Golang, Python, C#, JavaScript/Node, etc).

On the frontend side, you are capable of developing web applications in TypeScript (or JavaScript) and dealing with HTML/CSS. You have worked with at least one of the popular frontend frameworks (such as React, Angular, or Vue.js), and build tools (like grunt, gulp, bower, npm, or webpack).

And when it comes to the backend, you have prior experience in building data-intensive applications and working knowledge of database modeling and design. You feel comfortable when dealing with message queues, streams, caching layers, and REST APIs, as well as likely have some experience integrating with external APIs too.

On top of all that, you’re familiar with version control workflows, as well as have a good understanding of security and best practices for developing secure applications (e.g., the “Twelve-Factor App” principles sound to you at least familiar and fairly logical). Automated testing and testability are not an afterthought for you either.

Our tech stack:

  • Client-side: TypeScript / React / SCSS
  • Server-side: TypeScript / NodeJS / AWS Lambda (Serverless) / DynamoDB / Snowflake

We offer:

As a young company with solid funding, insightful knowledge of the crypto industry, and invaluable connections – the biggest offer we have for you is the opportunity for long-term growth, impact, and learning.

Onramper is a pre-SeriesA startup going through a stage of tremendous growth. As such, you have an opportunity to help build a unicorn with a close-knit talented team, while enjoying wide autonomy, ownership, and responsibilities over the products and solutions you will be working on.

Benefits & Perks:

  • Competitive compensation
  • Become a part-owner! We offer equity as part of your compensation package
  • Top-notch MacBook Pro and other necessary gear
  • Awesome office in the heart of Amsterdam. We don’t have a mandatory work-from-office policy, being remote-first. Yet you are always welcome to enjoy its facilities
  • Bi-monthly hackathons
  • Team events in and around Amsterdam
  • An international team with a dozen of different nationalities. We’re in The Netherlands, United Kingdom, Sri Lanka, Nigeria, Pakistan, and South Africa

We are asking for a lot. What we can offer you? 
- A legitimate meritocracy. We don't care if you fancy huh, we care if you are actually good at your job. Been passed over for the guy who's great at talking to the EVP about how you just need to move to microservices but just pushed several critical bugs to production? That will not happen here.

- The ability to work on a range of projects in different fields, industries, and stacks for companies ranging from early-stage startups to enterprise.
- Competitive pay with regular performance-based raises and other fun stuff including company retreats, a really nice office, health and pet insurance, a cake to embarass you on your birthday, etc.STACK

- git blaming some shitty code and realizing it was you, deciding to never git blame again
- having some super strong preference about the way something “needs to be done” that you read in a book, forum, conference or fancy colleague, being super militant about enforcing it and judgemental about people
who don’t already do it. and then realizing this was wrong 
- you had a stack you thought was universally superior but now you think people should just pick the right tool for the job
- being such an expert at something that you forget why anyone would think this is hard, then having to learn something new and sucking at it at first and remembering that programming actually is a skill, then getting
really great at that 
- Willing to work with new technologies, different environments. 
- Willing to work with everything and anything, Full Stack. 
- Experience working with Agile.

    Building the Future of Crypto 

    Our Krakenites are a world-class team with crypto conviction, united by our desire to discover and unlock the potential of crypto and blockchain technology.

    What makes us different?

    Kraken is a mission-focused company rooted in crypto values. As a Krakenite, you’ll join us on our mission to accelerate the global adoption of crypto, so that everyone can achieve financial freedom and inclusion. For over a decade, Kraken’s focus on our mission and crypto ethos has attracted many of the most talented crypto experts in the world.

    Before you apply, please read the Kraken Culture page to learn more about our internal culture, values, and mission.

    As a fully remote company, we have Krakenites in 70+ countries who speak over 50 languages. Krakenites are industry pioneers who develop premium crypto products for experienced traders, institutions, and newcomers to the space. Kraken is committed to industry-leading security, crypto education, and world-class client support through our products like Kraken ProKraken NFT, and Kraken Futures.

    Become a Krakenite and build the future of crypto!

    Proof of Work

    The Team

    Our team is focused on Kraken’s cryptocurrency operations: creating secure, reliable, and resilient services that handle client deposits and withdrawals across an ever-expanding universe of cryptocurrencies and blockchains. Ensuring the safety of our client’s assets is our top priority, while still delivering timely processing of transactions. Behind the scenes, we’re also building tools and services that allow us to transfer and rebalance funds to ensure continued operations (e.g. hot-to-cold, regional, and/or cross-chain transfer of assets), publish regular Proof-Of-Reserves reports to the public, and provide crucial information and insights to other teams, and lots more!

    Perseverance is key, crypto presents new challenges all the time and our clients are trusting us with their financial lives every day. There will be new tokens, new Layer 2s, and even a few Layer 1s along the way. You’ll need to build and maintain trusting relationships with each of your team members and peers (including cross-functional ones!) in order to succeed. It’s a true team effort as we work alongside our security, SRE, product, client experience, data, and other engineering teams to bring new things to life, and we do it all while assuming the best intent of our colleagues and acting with professionalism!

    This role is ideal for a hands-on people and technical leader that’s passionate about crypto and software engineering. You understand the tech and what’s going on at ground level and facilitate your team into making great decisions, but you’re careful not to let your own opinions outweigh those of others, and strike a healthy balance between trusting the way your team does things currently and challenging them to strive for something better. You find ways to make your team better and deliver: expedite a process, get rid of a blocker, get repetitive work off team members by handling it and/or automating it, and more.

    The Opportunity

    • Manage and grow a team of highly qualified and experienced engineers

    • Responsible and accountable for facilitating and contributing to deliverables

    • Design, develop, and maintain high-quality services in TypeScript (Node) and Rust

    • Spend about 25% of your time writing code, we expect Engineering Managers to have their own ground truth and opinions formed through first hand experience, but not necessarily be “the expert”

    • Collaborate with cross-functional teams, including Security, Product, Finance, Design, and Client Experience, to ensure seamless integration of new features and improvements

    • Maintain a security-first mindset by staying informed of the latest trends in blockchain technologies, and Web3 in general

    • Help scale the team by hiring and growing passionate engineers committed to excellence

    • Lead by example and nurture talent in a crypto-focused team, focusing on the growth of developers and ensuring their workload leaves them both challenged and fulfilled

    • Help identify, analyze, and resolve bottlenecks and inefficiencies in processes and codebases

    • Own, drive, and be accountable to KPIs pertaining to reliability, resiliency, durability, and uptime. Most of all, ensuring the continuity of crypto operations

    Skills You Should HODL

    • Deep understanding of the Ethereum ecosystem and EVM 

    • 7+ years of experience in software development

    • 2+ years proven track record of managing high performance engineering teams

    • Hands-on experience in blockchain or web3 applications, familiar with EVM and contract interaction details

    • Great generalist skills, able to engage new code/technologies at a surface level quickly

    • Proficiency in TypeScript (Node) and/or Rust

    • Familiarity with modern build pipelines and tooling

    • Deep knowledge of software development and delivery best practices; you can identify bottlenecks and/or obstacles holding back your team and find ways to help them move faster

    • Experience driving solutions to key business problems, especially navigating and resolving ambiguity

    • Bachelor's degree in Computer Science or a related field, or equivalent experience

    #LI-Remote #LI-DP1 #USCANBRUKEU

    Kraken is powered by people from around the world and we celebrate all Krakenites for their diverse talents, backgrounds, contributions and unique perspectives. We hire strictly based on merit, meaning we seek out the candidates with the right abilities, knowledge, and skills considered the most suitable for the job. We encourage you to apply for roles where you don't fully meet the listed requirements, especially if you're passionate or knowledgable about crypto!

Been passed over for the guy who's great at talking to the EVP about how you just need to move to microservices but just pushed several critical bugs to production? That will not happen here.
    - The ability to work with other people like you. And the joy of not having to work with people who aren't - no shitty devs, assholes, or devs who spend 2 hours a day working and 6 hours on TikTok and spreading office gossip.
    - An intensive onboarding bootcamp where you will be challenged, tested, and learn a ton. While we don't like firing people or having them quit, we care more about guaranteeing #2 and this process is meant to weed people out who aren't a fit.
    - A highly supportive atmosphere. We have a high standard for performance, but we will do everything we can to help each individual attain it. Everyone at all levels of the company is willing to pitch in and provide advice, mentorship, or even jump in to get our hands dirty coding, organizing the backlog, or talking to
    clients when a team needs extra support. We're in this together. 
    - The ability to work on some of the most exciting technical and product challenges that exist today. We work with clients, who bring us in to work on their most critical and important tasks because they know we can deliver and on our own internal projects which solve real needs. We also work on complex blockchain
    projects with legitimate use cases. We also build best-in-class web and mobile applications and have some of the world's best data scientists.
    - The ability to work on a range of projects in different fields, industries, and stacks for companies ranging from early-stage startups to enterprise.
    - Competitive pay with regular performance-based raises and other fun stuff including company retreats, a really nice office, health and pet insurance, a cake to embarass you on your birthday, etc.STACK

    - realizing in the middle of the night you forgot a major edge case that you can’t believe hasn’t burned you yet and need to fix asap
    - git blaming some shitty code and realizing it was you, deciding to never git blame again
    - having some super strong preference about the way something “needs to be done” that you read in a book, forum, conference or fancy colleague, being super militant about enforcing it and judgemental about people
    who don’t already do it. and then realizing this was wrong
    - you had a stack you thought was universally superior but now you think people should just pick the right tool for the job
    - being such an expert at something that you forget why anyone would think this is hard, then having to learn something new and sucking at it at first and remembering that programming actually is a skill, then getting
    really great at that

    • We’re an early stage martech and analytics company with a remote team, headquartered in Berlin, Germany.
    • 7+ years of professional experience is ideal for this role.
    • You’ll be joining a small but experienced engineering team.
    • Our codebase is TypeScript on the frontend and backend.
    • There’s a wide variety of projects to work on and things to learn, such as our React web app, analytics infrastructure on GCP, customer API, JS snippet, and AI-driven experimentation.

    IMPORTANT: You must currently be a resident of Europe within the 29 countries listed below for us to be able to hire you. We are not relocating candidates or sponsoring new visas, but can help you keep an existing work visa within Germany if needed.
    About the role
    Affilimate is looking for a Senior Fullstack Engineer experienced with TypeScript, React, and Node.js to join us.
    Our product is a web analytics and data platform used by media companies and creators. We track millions of pageviews per day and millions in revenue every month for our customers.
    This role is perfect for an experienced, product-oriented software engineer, who strives to build beautiful, user-friendly products across the full stack.
    You should love talking to users, participating in product research, and be able to work autonomously on projects without having all the requirements spelled out in advance.
    Our team is small and our processes are efficient. You’ll eventually ship code to production on a daily basis. You should be able to balance a high level of code quality with practical decision-making and bias towards shipping early and often.
    Our cofounder, Monica Lent, is a software engineer with 10+ years experience, and together with the team will work with you to get you up to speed quickly.
    Technologies
    Our codebase lives in a monorepo of 300K+ lines of TypeScript.
    We’re running on Google Cloud Platform, with a React.js frontend (built with Firebase, Material UI, Emotion, and Recharts) and a serverless backend running on Cloud Functions and GCP-managed databases.
    Bonus if you have experience with columnar databases like BigQuery and ClickHouse, though we also use Firestore, Postgres and Redis for specific use cases.
    Typical tasks
    • Building new features end-to-end based on first-hand customer research you participate in and iterating on design mockups.
    • Building new tools that ingest and display large volumes of analytics, transaction, and ecommerce data in a performant and user-friendly way.
    • Optimizing and scaling existing workflows, for example by introducing streaming, gradual data fetching, intermediate storage in buckets, or creating new systems altogether.
    • Working on our customer-facing API, exposing some of our powerful internal endpoints to customers in a safe way.
    • Data visualization, including pulling data from our JS snippet or integrations, and bringing that date to the frontend and then visualizing it.
    • Enhancing features with AI where it makes sense, mindfully and responsibly, so we can provide innovative ways for our customers to leverage their proprietary data.
    • Integrating 3rd party APIs following proven patterns and systems.
    • And of course, maintenance, refactoring, and fixing issues reported to our Support team, as well as writing internal documentation.
    In general, there’s a wide variety of work, so there’s a lot to learn no matter your background.
    Product
    Affilimate is an analytics platform that helps media companies, marketers, and creators grow their website's affiliate revenue by understanding exactly where their revenue is coming from.
    We do that in three main ways:
    1. Aggregating transaction data from multiple data sources in one place via APIs and other integration methods.
    2. Connect revenue back to specific content and links, using our web analytics platform and JavaScript snippet.
    3. Optimization tools like heatmaps and revision tracking, which content editors can use to improve performance.
    We’re already handling millions of requests per day and looking to scale 100 - 1000x.
    We’re also expanding our product offering beyond data and analytics, and are looking for product-minded engineers to help spin those projects up.
    Location
    You must currently live and be able to work in Europe in one of the following countries:
    Austria, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, or the United Kingdom.
    We would especially like to hire within Germany or Poland, as that’s where our existing team is and we do quarterly coworking and planning in person. For strong candidates, we can expand the area to the 29 countries listed above.
    If you need an employer to continue working on a German work visa, we can probably support you!
    We are not able to sponsor relocation to Europe or visas in other European countries.
    Benefits
    • Work remotely and enjoy flexible hours.
    • Low stress, low meetings, no corporate politics.
    • Internal transparency of our company performance via weekly All Hands.
    • Influence the product direction and see your work directly impact the business.
    • Build the product based on direct customer feedback, be part of customer interviews and onboarding, and implement improvements based on first-hand experience.
    • Opportunity to take on more responsibility as the team grows.
    • Use modern tools for work, like Slack, Linear, and Slab.
    • Quarterly in-person coworking with other engineering team members in Europe.
    • Annual offsite with the rest of the company.
    • Company-provided laptop with upgrades every 2 years.
    • 300 EUR initial remote office budget.
    • Local benefits (varies by country).
    What we’re looking for
    Our ideal candidate fits the following profile:
    • 7+ years prior professional experience. You should have strong technical experience, ideally working in an early to mid-stage startup.
    • Very strong understanding of data structures. A huge part of the job is data aggregation and transformation, so you can store/retrieve/display data in different ways.
    • Strong TypeScript skills. You need to be comfortable working in a TypeScript codebase, and fundamentals like using generics, union types, etc.
    • Experience with React. A big part of the job is building and improving our UI.
    • Command line fundamentals. You should be comfortable working on the command line as needed. Comfort with git is also a must.
    • Focus on security and performance. Performance matters at our scale, and nothing is more important to us than security of our confidential customer data.
    • Care about design and UX. You should be comfortable with CSS, and pay attention to detail when implementing designs.
    • Strong English communication. You should be able to clearly discuss technical topics in English.
    We're building a diverse team, and welcome non-traditional backgrounds. We don’t care if you have a CS degree or not. We do care about years of professional technical experience and as well as the non-technical skills that come along with it.

    • Experience on Google Cloud Platform.
    • Experience working on data-intensive projects and related skills.
    • Comfort with SQL and experience working with relational databases like Postgres, columnar databases like BigQuery/ClickHouse, and in-memory storage like Redis.
    Expectations
    • You can work independently while still asking questions when something isn't clear.
    • We'll start by tag teaming over Slack as you learn the product, domain, and codebase.
    • After 2-3 weeks, you'll be able to independently handle small features, add functionality to existing screens, and fix simple bugs.
    • After 1-2 months, you'll be able to implement small to medium-sized, standalone features, build new screens, and fix more complex bugs.
    • After 3-5 months, you'll be able to contribute to system refactors and more architectural-level changes.
    Hiring process
    • Fill out the application form linked below. You'll hear from us within 1 week.
