About the role

Key responsibilities & impact

Own the delivery of a scoped set of developer platform capabilities end-to-end (design, implementation, rollout, iteration).
Build and evolve paved roads (golden paths, service templates, scaffolding) that make it easy to deploy, operate, and scale services.
Run tight feedback loops with engineers across product and ML teams; measure adoption and eliminate common friction points.
Drive improvements to GitOps workflows via ArgoCD and Terraform automation via Atlantis.
Harden CI/CD on GitLab CI, including pipeline performance, safety, and developer ergonomics.
Design progressive delivery patterns (canary, blue/green) as reusable platform primitives.
Contribute to SLI/SLO frameworks and shared observability primitives (Prometheus, Grafana, Loki, Tempo, OpenTelemetry).
Participate in the platform team's on-call rotation; reduce toil through automation and better system design.
Improve incident response and postmortem practice so learnings translate into systemic fixes.
Embed secure-by-default patterns into platform templates (secrets, IAM, RBAC, NetworkPolicies).
Partner with security on compliance posture (SOC 2, ISO 27001) without slowing delivery.
Partner with infrastructure/SRE owners on Kubernetes and core cloud foundations (networking, storage, cluster/platform primitives) where it directly improves developer workflows.
Evolve cloud-native abstractions so the platform remains portable and resilient as our footprint grows (GCP today, with future optionality across providers).
