• Design, implement, and maintain scalable systems for uptime, resilience, and performance, while defining and enforcing SLOs, SLIs, and SLAs with product teams.
• Own incident detection, escalation, and resolution, developing playbooks for failure scenarios and leading post-mortem analyses with corrective actions.
• Build monitoring, logging, and alerting systems, and develop automation for deployments, maintenance, and toil reduction.
• Drive CI/CD improvements and maintain operational documentation, runbooks, and best practices.
• Partner with developers on reliability by design, fostering shared responsibility for observability and fault tolerance.
• Enforce security policies and standards, collaborating on vulnerability identification and mitigation strategies.

• Observability Platforms:
  Hands-on experience with Datadog for metrics, distributed tracing, log management, and APM.
• Chaos Engineering:
  Experience applying chaos engineering practices to proactively validate system resilience.

Preferred Skills & Attributes

• Tactical & Operational:
  Ability to drive team initiatives, own delivery outcomes, and act as a reliability champion.
• System Reliability Advocacy:
  Champion robust system design and operational excellence across engineering and product teams.
• Analytical Problem-Solving:
