    Requirements

    • •8+ years of related engineering experience, with a substantial portion focused on reliability, infrastructure, or platform engineering
    • •Demonstrated accountability for production systems — you have carried a pager for services that mattered and owned the outcome when they failed
    • •Strong software engineering fundamentals: you build and ship production code, not only configure tooling
    • •Experience defining and operating against SLIs and SLOs, and using error budgets to inform engineering priorities
    • •Depth in production operations: incident command, post-mortem analysis, capacity planning, and observability
    • •A record of preventing recurrence — reducing incident classes and operational toil, not just closing tickets
    • •Experience driving changes that span multiple teams, and the communication skills to build alignment without formal authority
    • •A track record of improving the engineers around you through code review, design feedback, and mentorship
    • •Experience with large-scale distributed systems in a cloud environment

    What You'll Do

    • •Own the reliability posture of production services in your area — availability, latency, capacity, efficiency, performance, and the monitoring and alerting that makes them visible
    • •Define, instrument, and operate against SLIs and SLOs, and use error budgets to drive engineering priorities
    • •Identify trends and problem areas that threaten stability, and provide a path forward to mitigate risk before it reaches customers
    • •Drive down repair items and prevent classes of incidents rather than resolving them one at a time
    • •Improve detection, response, and recovery — reducing time to acknowledge, engage, mitigate, and restore, with fewer people pulled in
    • •Design for failure: strengthen failure domains, validate recovery paths, and make production changes safer to ship and safer to roll back
    • •Participate in on-call for the services you support, and lead the response when production is degraded
    • •Write post-mortems that identify true root causes, and drive the follow-up work to completion
    • •Oversee efforts to identify, diagnose, report, and document production problems across all reliability dimensions
    • •Write, configure, and deploy code that measurably improves service reliability — maintainable, reviewed, documented, and well tested
    • •Orchestrate complex changes across systems and services, documenting design changes, technical decisions, migration plans, and upgrades
    • •Lead debugging, troubleshooting, and analysis of service architecture and design
    • •Use code review to drive up the quality of your coworkers' code
    • •Reduce the operational overhead required to run infrastructure and services
    • •Drive projects from conception to completion for efforts spanning the concerns of your team
    • •Coordinate across programs, collaborating with others to estimate and communicate delivery timelines
    • •Break projects into milestones and tasks, track progress, and communicate updates to stakeholders
    • •Identify and communicate changes that may impact stability

    Nice to Have

    • •Familiarity with infrastructure-as-code, container orchestration, and GitOps-style delivery
    • •Experience with multi-region architecture, failure-domain design, or regional expansion work
    • •Background in chaos engineering, game days, or other proactive resilience validation

    Benefits

    • •competitive pay
    • •generous time off
    • •ample parental and wellness leave
    • •healthcare
    • •a retirement savings program
