• 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
