What are the responsibilities and job description for the Billing & Revenue Ops Manager position at Antithesis?
About Antithesis
We build a platform that finds the bugs other testing approaches never see. Antithesis runs your entire system inside a deterministic simulation, breaks it in every way we can think of, and hands you a root cause with a perfect reproduction — no flaky tests, no false positives, no "works on my machine." Engineering teams debug faster and ship with far more confidence.
AI-generated code has made this work more urgent than ever. Agents write code faster than any human can, but faster code isn’t better code if it’s buggy, stuck in review, or quietly failing in production. The verification bottleneck is real, and it’s growing. That is precisely the problem Antithesis exists to solve. We’ve spent years quietly rethinking how the world approaches software reliability, and we’re just getting started.
We’re well-funded, deeply technical, and headquartered in Northern Virginia with satellite offices in London and San Francisco. Our team is in the office daily, which is how we take on hard problems together. If that sounds like fun to you, keep reading.
About The Role
Antithesis is looking for a Billing AR Manager to own the end-to-end billing and accounts receivable function. You'll build the systems, processes, and controls behind our revenue cycle from invoice generation to collections and keep our AR data clean as we scale. This role is hands-on. You should be comfortable designing workflows where limited process exists, working with sales and legal on deal structure, and talking directly with customers when issues arise. We're in the office daily in Vienna, VA.
