About Gumloop

Gumloop is an AI operating system for enterprises. We enable business teams to build and deploy AI agents in Slack or Microsoft Teams that automate work across hundreds of in-house integrations.

Our workflow product allows teams to build automations on a visual canvas using modular nodes — no engineering bottlenecks required. Our observability, security, and MCP hosting product (Gumstack) gives InfoSec teams the confidence to deploy Gumloop, with its full capabilities and integrations, across their organization.

We’ve raised $23.5M from First Round Capital, Y Combinator, Nexus Ventures, and Shopify Ventures.

Our goal: give the people who do the work the power to automate it.

The Role

You will own Gumloop’s testing strategy end-to-end.

Today we have ~25% test coverage, a basic testing system, and minimal browser automation. You will define what “quality” means at Gumloop and build the systems to enforce it.

You will:

  • Design and implement our testing strategy (unit, integration, E2E, CI)
  • Build a scalable testing framework with clear standards and guardrails
  • Develop systems for testing AI-driven workflows and agents
  • Reduce flakiness, increase coverage, and improve deployment confidence
  • Automate aggressively; use manual QA deliberately and sparingly
  • Partner with product and engineering to prevent bugs before they ship

  • Have designed tests for nondeterministic systems (LLMs, AI agents, etc.)
  • Thrive in small, fast-moving teams
