• Ensuring fault tolerance, efficiency, and security across the platform.

What We’re Looking For

Essential Skills:

• Strong experience in backend development using Node.js & TypeScript building applications that have proven to scale
• Deep understanding of and experience with distributed systems - scalability, high availability, and performance tuning.
• Strong experience with CI/CD, AWS.
• Experience building or contributing to production DeFi or web3 projects.

Highly desirable:

• Prior work with real-time trading systems or large-scale on-chain applications
• Solidity/smart contract knowledge is not essential but a bonus.

Why Join Us?

• Fully remote (AEST ± 3 hours)
• Get paid on-chain (USD stables)
• Work alongside world-class engineers building core DeFi infrastructure
• Get early ownership in a protocol with $700M+ TVL and serious momentum
• Solve complex, technical problems with real user impact

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

• 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.
