Job Summary
Build and own the reliability platform, implementing comprehensive monitoring with OpenTelemetry and distributed tracing to establish SLOs and error budgets. Engineer self-healing capabilities including auto-remediation, error-budget-gated rollbacks, and automated traffic rerouting while designing chaos experiments across the AWS estate. Maintain 24/7 operational readiness through automated deployments, blue/green releases, and zero-downtime patching strategies. Mentor junior SREs and Reliability Champions on production engineering discipline, facilitate blameless post-incident reviews within five days, and evolve SRE standards for the organization. Work with development teams to design SLOs on customer journeys and assist in system design and capacity planning.
Required Qualifications

- circuit breakers, bulkheads, idempotency, graceful degradation, and load-shedding
- high-throughput, low-latency environments preferred
- on-call experience on production systems

- experience designing and executing hypothesis-driven experiments with blast-radius controls and gap-to-impact-tolerance analysis
- AWS FIS, Gremlin, or equivalent
- at ease in a guild or community-of-practice model
- comfortable writing RFCs, presenting at engineering forums, and building standards that others will adopt
- Track record in high-throughput, production environments (financial services, trading platforms, or similar mission-critical systems preferred)
- Demonstrated ability to improve system reliability and performance at scale
- Experience working collaboratively with development teams to implement observability and reliability improvements
- Strong troubleshooting skills in distributed systems environments
