Create observability across build systems, workflow services, repositories, test environments, model endpoints, and platform components using logs, metrics, traces, and dashboards.
Support troubleshooting of build failures, flaky pipelines, missing dependencies, environment drift, performance bottlenecks, and handover-readiness gaps.
Partner with software, SRE, testing, and security teams to define runbooks, operational KPIs, risk indicators, and audit-ready evidence packs for release decisions.
