Site Reliability Engineer - CTJ - POLY

Owns reliability architecture and end-to-end service understanding (dependencies, failure modes, and customer journeys) for distributed systems at scale. Defines and improves service health via SLIs/SLOs, error budgets, and well-defined operational readiness criteria. Drives cross-team reliability reviews and recommends design changes, runbooks, and safe rollout/rollback strategies that improve availability, latency, performance, and efficiency while managing cost. Maintains deep, current expertise in cloud reliability practices and the evolving technology landscape. Drives adoption of new platform capabilities and operational patterns (e.g., progressive delivery, resilience testing, chaos engineering where appropriate). Mentors engineers through design reviews, incident walkthroughs, and knowledge sharing to raise the reliability bar across related services. Implements reliable, scalable, and high-performance changes using SRE practices (progressive delivery, feature flags where applicable, safe rollouts/rollbacks). Owns implementation and rollback plans, validates operational readiness, and reduces toil through automation, self-healing, and standardized playbooks. Leverages telemetry and production signals to identify reliability risks and recurring failure patterns, then ships configuration changes, code fixes, or automation to address root causes. Expands infrastructure-as-code and operational tooling so teams can manage platforms and services safely and repeatably through code and policy. Builds and improves observability (metrics, logs, traces, dashboards, alerts) and uses it to detect, diagnose, and prevent incidents. Defines actionable alerting, reduces noise, and ensures instrumentation supports SLO reporting and rapid troubleshooting. Develops automation to validate telemetry pipelines and to enable automated mitigation and safer incident response. Participates in on-call rotations and leads response for complex, high-impact incidents by establishing incident command, assessing impact, coordinating responders, and driving mitigations to restore service within SLOs. Produces and contributes to blameless postmortems with corrective and preventative actions (CPAs), tracks them to completion, and implements automation and guardrails to prevent recurrence. Applies secure-by-design and compliance requirements to operations, monitoring, and automation (least privilege, auditability, change control, and data handling). Partners with security, privacy, and compliance teams to identify gaps, prioritize fixes, and implement automated controls and detection to prevent repeated violations Embody our culture and values Master's Degree in Computer Science, Information Technology, or related field AND 2+ years technical experience in software engineering, network engineering, or systems administration OR Bachelor's Degree in Computer Science, Information Technology, or related field AND 4+ years technical experience in software engineering, network engineering, or systems administration OR equivalent experience.
