Site Reliability Engineer II

The SRE II sits at the intersection of software engineering and platform operations.

This is a mid-level individual contributor role. You are expected to execute technical work independently, drive reliability improvements end-to-end, and participate meaningfully in architecture discussions. You will carry on-call responsibilities as part of a shared rotation with a well-defined escalation model and a strong blameless post-incident review culture.

The team is in the middle of a meaningful platform evolution: formalizing multi-tier release pipelines (Dev QA Integration UAT Prod) with ArgoCD-based approval gates, building out SLI/SLO frameworks, and migrating toward full GitOps. You will be a hands-on contributor to all of it.Key Responsibilities: =========================...
