About Antithesis

We provide a platform that helps engineering teams identify and resolve bugs that traditional testing approaches miss. Antithesis runs your entire system in a deterministic simulation, breaks it in every way imaginable, and hands you a root cause and a perfect reproduction — no flaky tests, no false positives, no "works on my machine". This allows engineering teams to debug faster and ship with greater confidence.

The rise of AI-generated code has made what we do more important than ever. Agents can write code faster than any human — but faster code isn't better code if it's buggy, stuck in review, or issues are slipping through the cracks undetected. The verification bottleneck is real, and it's growing. This is exactly the problem Antithesis exists to solve. We've been quietly reinventing how the world thinks about software reliability, and we're just getting started.

We're well-funded, deeply technical, and building a platform that tackles one of the most complex yet important problems in modern software engineering. If that sounds like fun to you, keep reading.

About the Senior Account Executive position

Antithesis is looking for Senior Account Executives with experience selling developer tools to highly technical customers, from senior engineers to C-level engineering leadership.

As a Senior Account Executive, you will report either to a Regional Sales Leader (West) or directly to the VP of Sales, depending on location.

• Represent the voice of the customer in product discussions with engineering and product teams.

• Drive successful customer adoption by clearly articulating value, ROI, and integration considerations.

• Mentor new Account Executives and contribute to a strong, collaborative sales culture.
