About the role

Improve metrics, logs, traces, and alerting so issues are detected early, attributed precisely, and debugged with code-level confidence.
Identify repetitive operational work and eliminate it with software - automation, self-healing behavior, better defaults, better tooling - rather than absorbing it as ongoing overhead.
Run capacity and performance work before incidents arise.

Build the observability layer. Improve metrics, logs, traces, and alerting so issues are detected early, attributed precisely, and debugged with code-level confidence. Push instrumentation upstream into the services we own.
Lead incident response. Act as incident commander when needed, drive blameless postmortems, and turn findings into concrete engineering work that lands. Build the muscle in the team so this isn't centralized in any one person.
Improve developer experience especially where it removes operational friction or improves change safety. Where internal tooling or platform gaps slow the team down, build or contribute the fix. Prefer leverage over heroics.
Establish meaningful SLIs and SLOs with product and engineering partners, manage error budgets, and use them as real inputs to prioritization rather than dashboards no one reads.
Deep system design experience: distributed services, asynchronous messaging, storage tradeoffs, API design, idempotency, consistency, backpressure, and graceful degradation.

You can hold a high reliability bar while still helping a fast-moving squad ship.
