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.

• Help define and refine Antithesis's customer qualification criteria and sales process as the company scales.

• 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.

• Partner with marketing to refine messaging and sales materials based on market feedback.

Our Ideal Senior Account Executive Will:
