Senior Software Engineer

Role Description

ZoomInfo is where careers accelerate. We move fast, think boldly, and empower you to do the best work of your life. You’ll be surrounded by teammates who care deeply, challenge each other, and celebrate wins. With tools that amplify your impact and a culture that backs your ambition, you won’t just contribute. You’ll make things happen–fast.

What You'll do:

• Own a production GitOps deployment API and CLI (TypeScript/Node, NestJS) that a large share of our services depend on to ship—operating it reliably, evolving its capabilities, and being the engineer teams turn to when a deploy doesn't go as planned.
• Maintain and extend self-service deployment tooling built on ArgoCD ApplicationSets and Helm that rolls services out to GCP Cloud Run, including its manifest schema, chart, and ApplicationSet integration.
• Own a shared internal TypeScript package ecosystem (an Nx monorepo) consumed across dozens of services, plus the application ingress / edge-routing layer and its Helm charts—keeping consumers unblocked and the contracts stable.
• Build high-performance internal tools and APIs in Go (Golang) to manage infrastructure metadata and lifecycle.
• Design complex, long-running workflows using durable execution frameworks (like Temporal) to orchestrate tasks across Git, cloud providers, and CI/CD pipelines.
• Develop and implement Model Context Protocol (MCP) servers and Agentic AI workflows to automate the creation, upgrading, and auditing of infrastructure configurations.

Qualifications

• 8+ years of software engineering experience, or equivalent, including building and operating infrastructure, platform, or delivery systems that other teams depend on.
• Strong experience in at least one of the following:
  • Delivery / GitOps tooling — ArgoCD (ideally ApplicationSets), Helm, GitHub Actions, and the GitOps model of declarative, Git-driven deployment
  • Backend services & shared libraries at scale—building APIs and reusable packages that many other services consume
• Proficiency in Go or TypeScript/JavaScript, with hands-on experience in—or a genuine willingness to ramp quickly on—the other.
• A demonstrable understanding of software architecture, design patterns, and building scalable RESTful APIs.
• Experience with Kubernetes (K8s), serverless runtimes (GCP Cloud Run or equivalent), and major cloud providers (GCP and AWS).
• Comfort inheriting an unfamiliar, production-critical system from a transitioning team—prioritizing, asking the right questions before the original owners leave, documenting as you go, and stabilizing before reshaping.

Requirements

• Bonus Point:
  • Experience operating a deployment platform that other teams depend on.
  • Experience with Temporal (or similar workflow engines like Cadence or Airflow) for stateful distributed systems.
  • Proficiency with Terraform, including modular, reusable modules.
  • Practical experience with Agentic AI, MCP (Model Context Protocol), or A2A (Agent-to-Agent) frameworks.
