Job description

Secure National Infrastructure

We are seeking high-caliber Infrastructure / SRE Engineers to design, build, and operate mission-critical production infrastructure supporting vital UK government and national security missions. This is an environment operating at startup velocity to solve complex, national-scale engineering problems with true architectural ownership and autonomy from day one.

What You’ll Be Doing:

• Taking end-to-end operational and architectural ownership of high-security, distributed production platforms.
• Architecting, deploying, and maintaining resilient container runtimes using Docker and Kubernetes.
• Designing automated CI/CD deployment workflows and building internal tooling to optimize developer velocity and platform resilience.
• Developing automation, monitoring, and telemetry infrastructure to ensure ultra-low downtime and rapid incident response across complex distributed systems.
• Driving platform innovation and automation initiatives with modern tooling, cutting through operational bureaucracy.

What We’re Looking For:

• 1–5 years of commercial experience in Infrastructure Engineering, Site Reliability Engineering (SRE), or Platform Operations.
• Software-minded engineering approach: strong hands-on experience building, automating, and deploying production architectures (not just operational support/debugging).
• Demonstrated ownership mindset: comfort working in rapid iterations, driving solutions independently, and operating in secure, high-trust environments.
• Degree in Computer Science, Computer Engineering, or related discipline from a top-50 university.

Must-Haves:

• Active UK Developed Vetting (DV) security clearance.
• Sole British nationality (dual nationals cannot be considered due to national security compliance).
• Hands-on expertise with Docker, Kubernetes, and container orchestration in production.
• Production Linux systems engineering and cloud/distributed systems delivery (AWS, GCP, Azure).
• Residency or willingness to relocate within 30 minutes of the secure London site.

Location & Working Setup:

• Hybrid model based out of the London
