About the role

Key responsibilities & impact

Participate in on-call and incident response: Respond to production incidents, contribute to service restoration, and support clear communication during incidents. Over time, take increasing responsibility for leading incidents end-to-end.
Improve operational reliability: Identify recurring issues and reliability risks, and drive fixes through better alerting, automation, system changes, or process improvements.
Own parts of the production environment: Operate and improve Kubernetes clusters, cloud infrastructure, and core platform services, with growing ownership as familiarity increases.
Strengthen observability: Improve dashboards, alerts, logs, and traces so issues are detected earlier and diagnosed faster, with a strong focus on actionable signals.
Reduce operational toil: Automate repetitive tasks, simplify runbooks, and improve tooling to make on-call and day-to-day operations easier and safer.
Support safe change: Improve deployments, rollback mechanisms, and operational readiness to reduce the risk of incidents caused by change.
Contribute to operational practices: Write and maintain runbooks, participate in blameless post-mortems, and help improve incident response processes over time.
Collaborate closely with engineers: Work with product and feature teams to improve production readiness, service ownership, and reliability expectations.
