GTM Systems Administrator

We provide a platform that enables engineering teams to 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.

We’re looking for somebody to build and operate a full Go-To-Market (GTM) systems stack. You’ll spend some time stitching together existing SaaS tools and some time building solutions custom to us that overall result in a system that ensures data quality and system reliability, while providing automation and seamless workflows for a fast-growing sales team. This role assumes deep internal knowledge of Salesforce and associated tools.

This is a high-impact, hands-on role for someone who loves making systems work elegantly, enjoys partnering closely with Sales, Customer Success, and Marketing, and wants to build the operational backbone of a fast-growing startup. Success here will have measurable revenue impact, and there will be compensation upside to match.
