Ent is the intent-aware AI endpoint — reading human, AI, and app activity in real time to tell normal work from risky action and act at the moment of risk. Backed by Sequoia and Felicis.
About the role
This role owns end-to-end quality for new features as they ship: translating product intent into runnable coverage, building the frameworks that coverage runs on, and producing the test evidence that says whether each feature is ready to ship. The work spans the operator portal, the backend platform, and the endpoint agent, and includes making the team’s automated and AI-generated test scenarios trustworthy enough to gate a release.
What they're looking for
- 5+ years in software test, SDET, or quality engineering, with strong end-to-end and API coverage across UI, service, and integration layers
- Built a browser end-to-end framework from scratch and integrated it into CI, owning the framework itself and not only the tests that run on it
- Proficiency in Python and/or TypeScript, with Playwright (or an equivalent such as Selenium) driving parallelized suites
- API and contract testing (Pytest, OpenAPI-driven, Postman or similar a plus), with the judgment to anticipate schema-drift risk
- A record of turning ambiguous requirements into concrete, gating coverage
- Sound judgment on the test pyramid — where end-to-end coverage earns its cost, and where it belongs at a cheaper, more stable layer
More about this role
Ent is the intent-aware workspace security platform for securing human and AI-driven work. Built to protect productivity, the new attack surface, Ent understands not just what users and agents do but why, and intervenes at the moment of risk before incidents occur. Where existing tools see events, Ent sees intent, so security teams can step in at the moment of risk instead of investigating days later. Founded by Lou Manousos and Brandon Dixon, co-founders of RiskIQ (acquired by Microsoft) and the team behind Microsoft Security Copilot, Ent is in production with Global 2000 customers across hospitality, financial services, and defense, and backed by Decibel, Sequoia, Crosspoint Capital, Craft Ventures, Shield Capital, Felicis, and In-Q-Tel. We’re now hiring the team that will define this category.
Customer first. The product and the business are built around problems we’ve watched real security teams struggle with — not the other way around. Every roadmap conversation starts with what a CISO told us last week.
Humble. No drama. We hire people who share the mission and trust each other to deliver. Teamwork over showmanship. Accountability over politics. The work speaks louder than...
