## Description

We are looking for a Senior SRE Engineer to join our infrastructure team and take technical leadership over production resilience. This role sits at the Senior level on our Cloud/Platform/SRE career path - reliability engineering with a heavy focus on metrics and production systems. You'll define SLIs and SLOs, lead incident response as commander, drive observability strategy end to end, and mentor cloud/platform engineers as you go.
You'll work closely with Product and Engineering, balancing speed, quality, and long-term reliability, while making the architectural calls that keep our systems resilient under load.
Responsibilities
Reliability & Incident Management
· Lead incidents as commander: set and revise severity, and know when to mitigate first and diagnose later
· Own the incident record and timeline standard, including the link between deployments and incidents
· Communicate with stakeholders while an incident is active
· Conduct blameless postmortems and drive toil identification and elimination as measured work
Observability
· Implement the three pillars of observability (logs, metrics, traces) end to end
· Design metrics and query strategy - recording rules, dashboard design that separates on-call needs from analyst needs
· Define SLIs and SLOs for critical services, choosing the indicator that reflects user experience over the one that's easiest to measure
· Design alerting systems - routing, escalation, deduplication, and alert fatigue reduction (multi-window burn-rate alerts)
Platform & Production Systems
· Design workload health signals - liveness, readiness, and startup probes - and reason about workload lifecycle (SIGTERM handling, termination grace periods, connection draining)
· Build runbook automation and self-healing systems to reduce operational toil
· Contribute to CI/CD framework improvements and cost optimization initiatives
Technical Leadership
· Make architectural decisions for reliability-critical systems
· Mentor cloud/platform engineers
· Influence technical direction on infrastructure and platform decisions
