ZoomInfo ZoomInfo · Enterprise · Toronto, ON · 831 Engineering - Infrastructure Engineering

Senior Software Engineer to build and own services for ZoomInfo's Internal Developer Platform (Backstage), focusing on catalog ingestion, developer-facing features including AI-generated reports, and LLM-powered services to make data accessible to humans and AI agents. Requires strong TypeScript/Node.js, Backstage experience, and practical LLM integration.

What you'd actually do

  1. 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.
  2. Catalog & Entity Pipeline: Own the Backstage catalog and ingestion pipeline that syncs entities from Helm, ArgoCD, GCP, and GitHub — nightly and on-demand.
  3. Developer-Facing Features: Extend the platform with engineering maturity scoring, change management workflows, AI-generated reports, and test management tooling.
  4. AI Integration: Develop LLM-powered services and MCP servers that make catalog and engineering data accessible to humans and AI agents.
  5. Operational Excellence: Own service reliability on GKE via ArgoCD GitOps, PostgreSQL and Redis datastores, and Datadog monitoring — including incident response and runbook ownership.
