Principal Software Engineer (GTMO/Mesh)

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.

Mesh is ZoomInfo's internal AI platform. Thousands of employees use it every day — to run AI agents, build automated workflows, create microapps, and connect to the tools they already work in. It's a platform with a lot of moving parts, and a small engineering team that owns all of them.

We're looking for a Principal Software Engineer who raises the bar on how we ship, not just what we ship.

What you'll be doing:

• Owning features across the full stack — React frontends, backend APIs, cloud infrastructure — from design through production

• Responding to production incidents and shipping fixes

• Building and improving core platform capabilities: AI agents, orchestration workflows, microapp infrastructure, LLM integrations

• Developing SDKs and tooling for engineers who build on top of Mesh

• Championing quality and reliability — tests, coverage, habits that prevent regressions

• Collaborating across teams and supporting users directly through our Slack support channels

• Mentoring engineers through code reviews and technical guidance

Why Mesh:

• Small team, real impact — your contributions are visible and your opinions carry weight

• We use AI tools heavily in our own workflow — Claude Code, AI-assisted code review, LLM-powered automation

• Distributed systems, LLM reliability, workflow orchestration, real-time integrations — the problems are hard and varied

• We move fast and we're getting smarter about how we do it
