The Reliability Engineering team is the engineering-first function that owns the stability, observability, and operational quality of a multi-application production estate. It operates in close partnership with the engineering team that builds the agentic automation platform, and is in active transition from human-executed operations to engineering-led, agent-assisted reliability. Role summary You build the self-healing automation, author the runbooks, and turn root-cause analysis into durable engineering fixes that let the production estate heal itself instead of paging a human. You work within the standards the Senior Principal SRE Engineer sets — SLOs, error budgets, observability — and you're the one who encodes them into working automation and documented procedure. This is a hands-on individual-contributor role focused on execution and codification rather than cross-estate reliability strategy. You decide, in partnership with the Senior Principal SRE Engineer, which recurring patterns warrant a self-healing investment versus a documented manual runbook, and you build whichever is right. You are an individual contributor. You do not manage people. You partner daily with the Senior Principal SRE Engineer, the agentic automation engineering team, and Operations on validating outcomes. Success is measured by self-healing coverage, runbooks authored and adopted, reduced recurrence of known failure modes, and the safety record of every automation you sign off.
