Key responsibilities:

  • Respond to technical customer requests in accordance with our SLAs and own them until resolution.
  • Provide valuable customer feedback to the product team and identify opportunities for product improvements or solutions to common issues.

Currently, Phantom cannot support employees from the following countries and continents: Russia, Pakistan, Ukraine, Asia, Oceania, and Africa.

This role is fully remote; however, we’re only open to candidates based in the US, EU and UK. Currently, Phantom cannot support employees from the following countries and continents: Russia, Pakistan, Ukraine, Asia, Oceania, and Africa.

Responsibilities

  • Strategic Uptime & Reliability: Spearhead efforts to achieve and maintain optimal uptime and reliability across Phantom’s suite of products and services in AWS and Cloudflare. Identify potential areas of improvement and lead initiatives for infrastructure resilience.
  • Advanced Monitoring & Alerting: Architect, own, and optimize our comprehensive error monitoring and alerting stack. Ensure that our infrastructure proactively identifies potential issues before they impact our customers.

Why Work with Us

Opportunity

We are a team of experienced builders with a ton of traction in a big and growing market – our users are so passionate they were hacking their way into our private beta. We’ve acquired millions of users in our 2+ years and are adding more every week. We are by far the leading wallet on Solana, and have recently expanded onto other chains including Ethereum.

On top of that, there has never been a better time to work in crypto and on wallets in particular.

  • Wallets play a pivotal role: Wallets are responsible for on-boarding new users into crypto, and can make or break the user experience.
  • We are moving to a multi-chain world: New blockchains and scaling solutions are coming online and gaining traction, but are lacking decent wallets and bridges.
  • DeFi & NFTs are exploding: Interest in DeFi and NFTs has exploded, yet they are still an after-thought in existing wallets.

Benefits

  • Competitive salary and equity
  • Comprehensive insurance (medical/dental/vision) — 100% covered
  • Stipend for your ideal remote / WFH set-up: laptop, headphones, and any other work gear you may need
  • Flexible hours and a long-standing, supportive remote environment
  • Unlimited vacation: Take time when you need it (and we really mean it!)
  • 401(k) retirement plan
  • Wellness benefit
  • Daily lunch benefit

The target base salary for this role will range between $180,000 to $220,000 with the addition of equity and benefits. This is determined by a few factors including your skillset, prior relevant experience, quality of interviews and market factors (such as location) at the point in time of offer.

MetaMask is both a crypto wallet and a gateway to the decentralized web. Our tools help people create communities, play video games, access financial services, make payments, invest in assets, protect against economic turmoil, and more.

They all require an understanding and appreciation of the ethereum ecosystem, from dApps to DEXs and wallets to nodes.

In this role, you’ll be utilising technologies to enable visibility and understanding of transactions, working to keep people’s funds safe and secure. The services you will be working on are centrally hosted in the traditional Web2 sense and require monitoring and maintenance. You will develop and maintain public-facing API services supporting MetaMask users and developers.

THANK YOU! :)

Aiir is hiring a Senior Developer

About the Job
You'll be working on building new products, maintaining existing ones, and creating new features to delight our customers.
Your work will span front and back end. On the front, you'll be creating accessible user interfaces, beautifully functional components, and working closely with our design team to forge the best customer experience.
On the back, you'll be writing APIs, working with databases and serverless functions, looking after the health of our infrastructure, and considering how our products are deployed to the cloud and into the hands of users.
Initially, this role will be fully focussed on our new cloud-native music Scheduler product. You will get up to speed on how this product has been built, how it's deployed, what work is in progress, and the kinds of things we might like to tackle next. The product is about to go to market and will receive a lot of feedback, so things will move fast.
A strong understanding and experience working in Node.js is absolutely crucial for this, above anything else. Experience in AWS, in particular Lambda, would put you at a strong advantage. A bonus would be familiarity with the Architect framework which the product is built on.
In time, your responsibilities will expand to our other products. Some of the languages and frameworks you'd be using there include PHP, Twig, MySQL and React / React Native. We also utilise plenty of other AWS services, like RDS, Elasticache, CloudFront, S3 and SQS.
About You
You'll be experienced in building and maintaining modern web applications. You need to be passionate about native web standards, custom web components, and "HTML over the wire", all of which are cornerstones of the Scheduler product you'll be working on.
This is a remote position based in the United Kingdom. It's important for this role that you can relatively easily travel to meet and occasionally co-work with colleagues in the same team.
We're looking for someone who excels at working autonomously. As we work remotely, we're unable to watch over your shoulder, but frankly we'd never want to anyway. You love using your initiative and judgement to see something through, from idea to completion. You're fiercely organised, reliable and have a keen eye for detail.
Direct experience in everything we do is not required. What's important is that you're creative and curious. Show up willing to learn and you'll go far.
You're great at expressing yourself in writing, clearly and concisely. It's how we primarily communicate, so we'll expect you to take the time to write up your thoughts and give your attention to digesting those of others.
Above all, you're a kind and thoughtful person. You'll support your colleagues, bringing a positive spirit and enthusiastic attitude. You're not afraid to speak up when something's not right. You can expect to be heard and valued by a team that appreciates your feedback.
If you don't see yourself in our team right now, it doesn't mean we're not looking for you. If you join us, we hope to learn from you as much as you'll learn from us.
Pay and Benefits
The salary for this role is £43,000.
You'll get 25 days annual leave, plus bank holidays and your birthday. You will gain one extra day at the end of each year you're with us, up to 30.
We'll provide you with a MacBook, and anything else you need to optimise your working environment for the role.
We've written about what it's like working at Aiir, so make sure you read that too and are comfortable with our stance.
How to apply
Introduce yourself to us - we want to see the real you. Take your time with your application, there's no prize here for being first. Tell us why you want this job, not just any job. We want to hear about what you can bring to Aiir, and Aiir's role in your future. Make sure you tell us where you're located.
We want to see your code. If you're selected for interview, we'd like you to walk us through something you've written recently and are proud of. The code you present will need to be all of your own creation and you must have permission to share it with us. If you've participated in open source work of any kind, please include any relevant links in your application.
To apply, email: email
We're accepting applications until April 30th 2024. Don't necessarily expect to hear from us until that date, to give everyone a chance. If you're selected for interview, you'll hear from us soon after. The interview will be via Google Meet and will be with up to three of your future colleagues. If you're unsuccessful, we'll let you know as soon as we can.
We look forward to hearing from you!

We ❤️ startups & SMBs. Since 2013, we’ve been building a CRM  that focuses on better communication, without the hassle of manual data entry or complex UI. Our goal: double the productivity of every sales rep.
Our app’s frontend is a single-page JavaScript web app mostly written in React (originally built with Backbone.js). We bundle with Webpack and target only modern browsers.

Our UI updates in near real-time and is written in LESS/CSS (with flexbox and grid layout) using CSS modules and takes advantage of fun technologies like Websockets and WebRTC. We house our design system in Storybook.
We care about performance (e.g. route-based code splitting), maintainability, and testability of our frontend code. We sweat the UI/UX details and work collaboratively with the Product team throughout the design process. This means diving into lo-fi wireframes, and communicating continuously when those ideas are brought to life using Figma and code.
Our frontend app is built on top of our REST API & GraphQL endpoints. Our backend tech stack consists of Python/Flask, MongoDB, Postgres, Elasticsearch, and Redis. We run our services in Docker on AWS.
We ❤️ open sourcing our code and ideas on our GitHub and on The Making of Close, our behind-the-scenes Product & Engineering blog. Check our projects such as react-custom-scroller, use-infinite-scroll, use-abortable-effect, and smart-tooltip-delay or insights from our day-to-day work on such as Highlights From a Complex Downshift.js Refactor, A Case Study in"Reactizing" a Complex Backbone View, and Finding the cause of a memory leak in Jest tests.
About You
We're looking for an experienced full-time (or part-time) Frontend Software Engineer to join our engineering team. Someone who has a solid understanding of web technologies and wants to help design, implement, and launch major user-facing features.
You should have senior level experience (~5 years) building modern frontend applications in JavaScript, HTML, and CSS, with at least 3 years of that experience using React.
You should have significant experience designing, debugging, and optimizing frontend applications to make them fast and reliable. You have significant experience with REST APIs and thoroughly understand HTTP requests. You have experience participating in code reviews and providing overall code quality suggestions to help maintain the structure and quality of the codebase.
You should have great product sense and be able to think through user experience issues before diving into the code, and you exhibit a love for great UI.
You’re comfortable working in a fast-paced environment with a small and talented team where you're supported in your efforts to grow professionally. You are able to manage your time well, communicate effectively and collaborate in a fully distributed team.
Note: this role requires you to be located in an Americas time zone. If you're not located in one of these time zones, check out our other posting here
