Responsibilities

Own the tooling and services that power the next generation of our CI/CD pipelines—the GitOps deployment API/CLI ( TypeScript/Node, NestJS ), self-service deployment capabilities ( ArgoCD / Helm / Cloud Run ), the shared TypeScript package ecosystem (an Nx monorepo ), and the ingress layer—making the calls on how these systems evolve, integrate, and stay reliable as a large share of the company depends on them, in partnership with our CI/CD team.
Lead the stabilization and strategic evolution and stabilization of these mission-critical systems; prioritize technical knowledge capture and de-risk the highest-leverage deployment paths as the platform transitions to your ownership.
