Responsibilities
Operate against our existing SLIs, SLOs and error budgets, hold services to them, review and adjust targets as systems evolve, and use budget burn to arbitrate between reliability work and feature velocity.
Own the incident lifecycle end to end detection, response, mitigation, blameless postmortems with tracked follow-through troubleshooting across the whole stack (OS, application, database, cache, network), and mature the on-call rotation around it: alerts tuned for signal, runbooks kept current, MTTD and MTTR trending down.
Extend and improve our observability stack instrument new services, close coverage gaps in metrics, logs and traces, and raise dashboard and alert quality so teams can diagnose their own services.
Design and maintain safe release processes: canary, progressive rollout, automated rollback across dev, staging and production.
Eliminate toil through automation; treat repetitive manual operations as bugs to be engineered away.
Own infrastructure as code provisioning, configuration, policy, and the documentation around it.
Capacity planning, performance tuning and cloud cost efficiency forecast growth, model headroom, upgrade before saturation.
Implement and maintain infrastructure security controls secrets and credential management in Vault, access control, monitoring and response.
Conduct production readiness reviews and resilience testing for new and existing services.
Operate our MCP gateway and internal AI tooling as production infrastructure availability, access control, rate limiting, cost and usage visibility and apply AI-assisted automation to operational work such as incident triage, log summarisation and runbook generation.
Reliability and infrastructure

CI/CD delivery pipelines on GitHub Actions (or equivalent), including progressive delivery and automated rollback.
Bash plus working proficiency in a general-purpose language (Go, Python or similar) for building real tooling.
Monitoring and observability with Prometheus, Grafana and Google Cloud Operations instrumentation, dashboards, alerting and tracing.
Able to work independently on large, complex projects with minimal guidance.
AI-assisted operations
Practical experience applying AI and LLM-based tooling to engineering or operational workflows, with a clear view of where it helps and where it doesn't.
