Responsibilities

  • Define and own production-readiness standards covering observability, SLOs, runbooks, resource limits, graceful degradation, and policy compliance.
  • Build and maintain platform observability, including Dynatrace APM, Splunk log pipelines through Fluent Bit, Prometheus metrics, tracing, structured logging, and dashboards.
  • Define and implement SLIs and SLOs with engineering teams and stakeholders.
  • Own incident response practices, including detection, response, blameless post-mortems, and reliability improvements.
  • Drive resilience engineering through chaos testing, failover validation, load testing, and graceful-degradation validation.
  • Advise engineering teams on operability concerns, retry strategies, timeout tuning, circuit breakers, and back-pressure handling.
  • Support operation of legacy and new systems during migration, including traffic routing, parity, and cutover visibility.
  • Automate operational toil and build tooling that improves deployment confidence and platform operations.
  • Perform capacity planning for normal and peak traffic.

Requirements

  • Experience in SRE, production engineering, or operations for high-volume distributed systems.
  • Hands-on experience with observability platforms, distributed tracing, metrics, structured logging, and APM tools.
  • Experience defining and measuring SLIs and SLOs to guide engineering decisions.
  • Understanding of distributed-systems resilience patterns including circuit breakers, retries, timeouts, bulkheads, and back-pressure.
  • Experience with load and performance testing at scale and interpreting results to identify bottlenecks.
  • Comfort with AWS, Kubernetes, container orchestration, and infrastructure-as-code.
  • Experience with event-driven systems, Kafka, message-based architectures, lag monitoring, consumer group management, and partition rebalancing.
  • Ability to enable engineering teams through standards and tooling rather than deployment gatekeeping.
  • Dynatrace or equivalent APM experience is preferred.
  • Familiarity with payments, financial services, incident-management tooling, on-call practices, or chaos-engineering frameworks is preferred.
