About the role

Key responsibilities & impact

Improving the application: Work directly in the codebase (primarily TypeScript) to fix reliability and performance problems at the source.
Building observability that developers actually use: Design and run our monitoring, logging, and alerting (Prometheus, Loki, Alloy, Grafana).
Owning reliability targets: Define and measure SLIs and SLOs, wire up alerting that feeds them, and be the person who can say what 'reliable' means for our systems.
Leading incident response: Act as incident responder, and incident commander when needed. Run blameless post-mortems (AARs).
Automating away toil: Spot the repetitive operational work and write software to kill it.
