About Aztec At Aztec, our goal is to add privacy to Ethereum. In the current public blockchain paradigm, users and entities unknowingly broadcast data in the public, compromising privacy and security to get trustlessness. Not only are unencrypted blockchains inherently privacy-exposing, they require significant redundancy to compute and verify the legitimacy of transactions. Implementing scalable encryption in a public blockchain paradigm requires cutting-edge math and engineering. Thankfully, our team of scientists and engineers invented Plonk, the industry-standard zkSNARK, and Noir, the universal language of zero knowledge. Now, we’re building a first of its kind Layer 2 with private smart contracts. This requires new cryptographic primitives, a zero-knowledge DSL for writing contracts, a privacy-friendly execution environment, a carefully designed set of circuits that prove the validity of the chain to L1, a decentralized block-building and proving mechanism, and a top-tier user and developer experience. And it’s now time to bring it to market. We’ve raised $125 million from industry-leading investors including a16z crypto, Paradigm, Variant, Consensys, and a_capital, and we’re growing quickly.The Role We’re looking for a DevOps Engineer with deep Linux expertise and a passion for building developer-centric tooling.

Take ownership of Aztec’s custom CI system and internal build tools. Enhance and build CI dashboards to improve observability of engineering workflows. Harden CI infrastructure using least privilege principles and robust sandboxing. Implement productivity enhancements across C++, Rust, Solidity, and TypeScript build systems. Investigate and resolve low-level bugs related to Linux processes, signals, memory, and IPC. Collaborate face-to-face during your ramp-up phase in our London office. Optionally grow into a leadership role as the internal infrastructure team expands.

💡 Explore our CI system in action: http://ci.aztec-labs.com and the code here. About You You might be a great fit if you:

Prefer scripting custom Bash over fighting YAML in legacy CI systems. Experience with cgroups, kernel namespaces, virtual memory, /proc, and tracing syscalls. Extensive experience with terraform and AWS cloud infrastructure. Know Docker intimately, from minimizing image sizes to how it leverages kernel features. Have experience maintaining complex software stacks and CI systems at scale. Are comfortable with debugging process groups, signals, and build failures at the OS layer. Take pride in building secure, reliable, and fast developer infrastructure.

What We Offer:

Flexible, remote-first culture with HQ in London. Competitive salary + equity/token options. 25 days annual leave + bank holidays. Health, dental, and retirement benefits (based on location).

What We’re Building

Ares is the newest product under Fountain Platform, focused on building high-performance social trading platform for decentralized markets.

We believe trading has evolved — it’s no longer solitary. It’s cultural. It’s real-time. It’s driven by memes, narratives, and reflexive attention loops. Yet most platforms are stuck in static tools built for yesterday’s market structure.

Ares is built for what trading has become — and where it’s going. We fuse speed, signal, social mechanics, and cultural context into a unified trading experience designed for today’s markets — and tomorrow’s meta. At the core is a real-time intelligence layer that aggregates onchain and offchain data, surfacing the pulse of the market as it emerges. But information alone isn’t power — influence is. Ares turns trading into a collaborative, reputation-driven game where every trade is a signal, and every user is a node of intelligence.

We’re not building a better terminal. We’re building the next dominant trading platform — one where culture leads, conviction is rewarded, and traders move markets together.

We’re backed by top VCs and Alliance (tier 1 crypto incubator). This is your opportunity to help define what the future of trading looks like — from the ground up. This isn’t a typical job — and we’re not looking for typical people. We want resourceful, hungry, top 1% builders who move fast and think like founders.

About the Role:

We’re looking for a product-driven senior or staff-level engineer. Our engineering team tackles complex challenges at the core of our trading infrastructure and user experience. At Ares, engineering defines the culture, pace, and quality of everything we build — pushing the limits of what’s possible in crypto-native systems.

What You’ll Do

• Work directly with the CEO and have transparency into other aspects of the company
• Architect important systems and anticipate strategic and scaling-related challenges via thoughtful long-term planning
• Design and implement core infrastructure across the full stack — from high-performance frontends in Next.js + Tailwind to backend systems in NestJS, PostgreSQL, Redis, and Solana RPCs
• Work on transactional engines that optimize for execution speed, accuracy, and UX under volatile, memecoin-driven conditions
• Drive the architecture of our real-time trading intelligence layer, fusing onchain and offchain signals into actionable interfaces
• Build integrations with external services (Telegram, bots, alerting engines) to power novel product experiences
• Ship fast and often — we deploy product daily and treat working code as the ultimate source of truth
• Collaborate directly with founders and a small team of senior engineers in a high-bandwidth, fast feedback loop
• Engage with early users — from CT influencers to alpha groups — and shape features around real workflows
• Take ownership over what you build, with freedom to make autonomous decisions and move without bureaucracy

Our Tech Stack

Tech Stack: Nest.js, Solana, Redis, Postgresql, Typescript, Nodejs, Materialize, gRPC, Drizzle, Websocket, Google Cloud Platform, Terraform

You Might Be a Fit If You

• Have full-stack experience, ideally in performance-sensitive environments (e.g., crypto, fintech, gaming, real-time apps)
• Thrive in fast-paced, product-centric orgs where speed, autonomy, and ownership are the norm
• Can move independently but also communicate clearly in async workflows
• Care deeply about craft, clean abstractions, and performance
• Have strong user empathy and can translate real behavior into real product
• Have understanding of crypto and trading — and care about the details of how and why traders behave the way they do
• Want to work with other A-players — people who think like founders and ship like it

Why Join Us

• Work with a passionate team that is obsessed over product, velocity, and craft
• Ship real infrastructure that’s used by traders and degens daily — the kind of users who demand speed, precision, and performance
• Leave your mark on a product that could reshape how crypto trading is understood — not just features, but the foundation of how people will trade in the social-first, memetic era of DeFi
• It’s all greenfield — no legacy baggage, no bureaucratic blockers, just you, a fast team, and the freedom to build what you think should exist
• We’re backed by top investors and Alliance DAO, with deep ties to the best minds in DeFi
• Total flexibility — async, remote, and built for real builders who want to own their time and output
• You won’t be another cog. You’ll be a core part of shaping the next dominant trading platform

• Proven experience interacting with deployed Solidity contracts (reading state, sending signed transactions, gas estimation, event parsing).
• CI/CD mindset; you automate workflows with GitHub Actions (or similar) and treat infrastructure as code.
• Strong testing discipline: unit, integration, and E2E where it matters.
• Excellent written communication; comfortable in an async, globally distributed team.

Nice to have

• Experience with SQL
• Exposure to GraphQL (Apollo Server/Federation) — some internal services use it.

We are looking for an experienced JavaScript developer to join our Web team, who will take ownership of certain web-related areas at Status, including a web browser crypto wallet. Your role will include working on our crypto wallet and other other Status web assets while collaborating with colleagues across the stack (QA, other developers, ui/ux, product, etc.) to deliver great features to our users.

Our stack is built on modern foundations – a monorepo powered by TypeScript, React, Storybook, Vite, Vitest, Playwright, ESLint, Prettier, pnpm, and Turborepo. As we work in the open and are fully open-source, you can get a better idea of who we are and the work we are doing by browsing our Status Web repository. We strive to build solid foundations that will enable us to continuously make progress and provide composable and extensible solutions. We don’t expect you to have a background in everything we use, but we do expect strong JavaScript fundamentals and experience working with React, TypeScript, and crypto web browser wallets.

We function as generalists, often undertaking a variety of challenges, and deeply care about the quality of our work. We look forward to collaborating with experienced individuals who can operate independently, make important decisions, and take ownership. The ideal candidate is comfortable working in European (or nearby) time zones, along with the majority of the existing team, but we welcome applications from other regions as well.

Key responsibilities:

• Building secure, robust, and well-cached APIs
• Cost-effective calling of RPC and node provider APIs
• Working with various browser storage solutions
• Integrating libraries to create, sign, and decode transactions
• Building and maintaining the new React implementation of Status’ design system
• Collaborating with other people across the teams (QA, other developers, ui/ux, product, etc.)

You ideally will have:

• Clear and effective communication skills, both verbally and written
• Thoughtful and pragmatic problem-solving
• 5+ years of software engineering experience, with 3+ years of experience with React
• Experience writing modern, performant, and accessible React code
• Strong knowledge of JavaScript, and ideally TypeScript
• Experience with UTXOs, derivation paths, ordinals, and consolidations
• Experience with integrating hardware crypto wallets (Ledger, Trezor, QR-code crypto wallets, etc.) into a web browser wallet
• Prior experience working for an open source organisation / contributing to OS projects
• Comfortable working in (and experience of) start-up environments

Hiring process:

The steps may change along the way if we see it makes sense to adapt the interview stages, so please consider the above as a guideline.

• Call with our Talent Team
• Technical interview (a Q&A tech interview)
• Live coding interview
• Interview with Design Team

Compensation:

The expected compensation range for this role is negotiable, dependent on how we assess your skills and experience throughout our interview process. We are happy to pay in any mix of fiat/crypto.

🔥 🚀 We build the next level onramping toolbox for fiat-to-crypto transactions.

We are a fast-paced scale-up in the Netherlands, enabling access to web3 by bridging the world of Fiat Currencies (Euro, Dollars, etc.) with the world of Cryptocurrencies.

We provide an embeddable widget and API for crypto-native wallets to allow their users to buy cryptocurrencies globally, with over 130 payment methods. 

Our tech is used by Coinbase, Exodus, Opera browser and hundreds of other platforms for their 'fiat onramping' stack. By partnering with the best fiat-to-crypto payment gateways and presenting them in a single plugin their users can then buy crypto easily in-platform when needed. This is one of the most important intersections for web3/meta.

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.

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:

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
• Team events 
• Thursday drinks (optional) and intra-team table tennis championship
• An international team with diverse nationalities/backgrounds

Location:

While we have a preference for those that can join our office in Amsterdam, we're open to applicants from countries in timezones ranging from CEST to UTC+4. Longer term, there's possibilities of Visa Sponsorship.
