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.

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).
- Quarterly offsites for team collaboration and bonding.
- Conference and learning budget for continual professional development.
A chance to work on truly cutting-edge zero-knowledge infrastructure with some of the best minds in the field.
