You’ll make things happen–fast.

What You’ll Do

• Design & Develop: Build and own services across our 20+ microservice Backstage platform using TypeScript and Node.js, exposing REST and GraphQL APIs consumed by other services and the Backstage frontend.
• Catalog & Entity Pipeline: Own the Backstage catalog and ingestion pipeline that syncs entities from Helm, ArgoCD, GCP, and GitHub — nightly and on-demand.
• Developer-Facing Features: Extend the platform with engineering maturity scoring, change management workflows, AI-generated reports, and test management tooling.
• AI Integration: Develop LLM-powered services and MCP servers that make catalog and engineering data accessible to humans and AI agents.
• Operational Excellence: Own service reliability on GKE via ArgoCD GitOps, PostgreSQL and Redis datastores, and Datadog monitoring — including incident response and runbook ownership. Collaborate: Partner with engineering, governance, architecture, and infrastructure teams to translate needs into catalog models, golden paths, and self-service tooling.

What You Bring

• Advanced proficiency in TypeScript and Node.js with strong software architecture fundamentals
• Hands-on experience designing and shipping REST and GraphQL APIs in production
• Hands-on experience building or extending Backstage — plugin development, catalog model, software templates, and TechDocs
• Strong proficiency with PostgreSQL and Redis; MongoDB familiarity is a plus
• Experience with Kubernetes (GKE) and GCP — deployment, scaling, and production troubleshooting; hands‑on experience with ArgoCD, Helm, and GitHub Actions
• Working proficiency with Terraform for cloud infrastructure management
• Practical experience integrating LLMs into production services; familiarity with MCP or Agentic AI patterns

Education & Experience
