DevOps Engineer
I'm working with a well-funded, VC-backed Defence AI start-up tackling some genuinely difficult engineering challenges.
They're looking for a Lead DevOps Engineer who is as comfortable writing Python and building infrastructure as they are thinking about security.
This isn't a role for someone who just knows security frameworks, runs vulnerability scans or manages compliance.
They need someone who can code, automate, build tooling and take ownership of the infrastructure and security foundations behind complex AI systems.
🛠️ What makes this interesting?
→ Building and improving secure, reliable infrastructure for advanced AI systems.
→ Writing Python, developing internal tooling and automating complex engineering workflows.
→ Solving challenging DevOps, infrastructure and security problems hands-on.
→ Taking technical ownership of DevSecOps and influencing engineering decisions from day one.
→ Helping build and mentor a small, highly capable engineering team as the company scales.
Who am I looking for?
- Engineers with strong foundations in DevOps, software engineering, infrastructure and Python, alongside a solid understanding of security.
- You might already be a DevSecOps Lead, a Senior Platform Engineer, an SRE or a strong DevOps Engineer looking to take on more security ownership.
- You don't need to have "Lead" in your current job title.
- What matters is your ability to write code, solve difficult infrastructure problems, communicate technical decisions and help other engineers improve.
- This is a chance to own a critical engineering function, remain deeply technical and build a team around you.
