As Staff SRE Engineer, you set the technical direction for reliability across regions and services. You own the reliability strategy, define the standards and mechanisms that guide production operations, and raise the bar through design leadership, operational discipline, and mentorship. You remain deeply hands-on by designing and operating observability platforms, defining and governing SLO programs, leading high-severity incident response, building resilience and disaster-recovery automation, improving reliability of stateful and streaming platforms, and creating AI Ops workflows for triage, remediation, and self-healing.

Responsibilities

: Production reliability: own service-level objectives, error budgets, and production reliability outcomes end to end, and represent reliability in architecture and scaling decisions. Engineer observability: design and operate the observability stack so production services are fully instrumented and define the standards platform and application teams follow. Govern SLOs and error budgets: define and manage service-level objectives, run regular reviews with service owners, and drive corrective action when services consume error budgets unsafely.

Drive resilience: design and execute chaos experiments and validate that failure modes are covered by tested safeguards. Lead incident response: define the incident process and serve as incident commander for the highest-severity incidents, including security incidents within the coverage window. Run on-call and escalation: establish and manage rotations and escalation paths that provide continuous coverage with clean follow-the-sun handoffs.

Disaster recovery: own disaster-recovery testing and failover validation against defined recovery objectives and turn exercise findings into architectural and operational improvements. Cloud security posture: co-own cloud security posture management, runtime vulnerability detection, and configuration-compliance monitoring with DevSecOps. Data, streaming, and AI Ops: own reliability of stateful and streaming services, capacity planning and rightsizing, and autonomous agents for triage, predictive alerting, remediation, and self-healing.

Scale the team and broaden impact: mentor engineers at different seniority levels, set standards adopted across teams, and align Architecture, DevSecOps, Cloud Operations, and Product Development behind a shared reliability roadmap.

Requirements

: 7+ years of production engineering experience with recent hands-on reliability work. Hands-on, recent experience operating large-scale, fault-tolerant production systems on AWS or GCP. Observability ownership: have instrumented production systems and governed service-level objectives and error budgets, not only inst
