Principal DevOps Engineer

A fast-growing, venture-backed software company building an AI-driven data analytics platform. Its clients are government, security and financial-services organisations. The platform runs in the cloud, on-premise and in fully air-gapped environments.

The role
You'll be a senior, hands-on engineer who owns the platform's infrastructure from design through to production. You'll report directly to the CTO and work alongside a small DevOps team.

• Build and maintain an offline installer for air-gapped customer deployments
• Own the CI/CD pipelines and keep local developer environments consistent with production
• Run secure private networks with controlled egress
• Look after self-hosted observability: monitoring, logging, tracing and alerting
• Deploy and operate AI model endpoints and inference serving, including GPU capacity planning
• Support customer IT teams during installations and upgrades
• Keep architecture docs, a decision log and runbooks up to date

What you'll bring

• Extensive experience running production Kubernetes, both in the cloud and on-premise
• A track record of owning infrastructure end to end
• Strong Linux administration, networking and troubleshooting skills
• Infrastructure-as-code and CI/CD experience
• Scripting ability in Bash, Python or similar
