• 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

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. You’ll work closely with our CTO and engineering teams to enhance our internal infrastructure, CI systems, and productivity pipelines. This is a hands-on, high-impact role - ideal for someone who thrives on owning the tools that engineers rely on every day. What You’ll Do

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).

• Ability to query and optimise ClickHouse or another analytic DB, plus familiarity with MongoDB.
• Working knowledge of the Ethereum consensus layer (Beacon Chain duties, attestations, slashing conditions).
• 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.
