Recruiting Coordinator

We've been quietly reinventing how the world thinks about software reliability, and we're just getting started! At Antithesis, we start at the foundations. We run entire software systems inside a deterministic simulation and break them in every way imaginable. Every issue then comes with a perfect reproduction, so engineers can identify root causes fast instead of spending days trying to recreate what went wrong.

The rise of AI-generated code has made this work more urgent than ever. Agents can write code faster than any human, but speed doesn't matter much when the output is buggy, stuck in review, or slipping through undetected. The verification bottleneck is real, it's growing, and solving it is one of the most consequential problems in software right now.

We're well-funded and deeply technical, the kind of place where the hardest problems get the most attention and the best ideas win regardless of who has them.

We're looking for a Recruiting Coordinator to join our People team at HQ in Vienna, VA. You'll be the person who keeps our hiring process moving, organized, and candidate-friendly, from the first scheduling email through offer. This is a hands-on, detail-heavy role at a company that's hiring across engineering, GTM, and operations, so you'll get exposure to nearly every part of the business.

You'll work closely with recruiters, hiring managers, and interview panels to make sure candidates have a great experience and interviewers have what they need to make impactful decisions. Since our team is in the office daily, you'll also be a familiar face for candidates coming through HQ giving office tours and generally being a trusted member of the team.

• Own interview scheduling end to end, coordinating across multiple interviewers, panels, and time zones

• Manage candidate communication so every applicant knows where they stand and what's next

• Keep our applicant tracking system (Ashby) up to date

• Coordinate onsite interviews at our Vienna, VA office, including greeting candidates and giving tours

• Partner with recruiters and hiring managers to keep requisitions and pipelines organized

• Help build and improve recruiting workflows, templates, and processes as we scale

• Support offer logistics and handoffs to onboarding

• Pitch in on other People team projects as needed; we're a small team and everyone wears more than one hat

• Experience coordinating interviews or supporting a recruiting function, ideally at a fast-moving company or startup.

• Hands-on experience with Ashby or a similar applicant tracking system

• Strong organizational skills and the ability to juggle multiple searches and calendars at once without dropping anything

• Clear, friendly written and verbal communication; you'll represent Antithesis to every candidate who comes through

• Comfortable being in the office daily and giving tours to visiting candidates

• A high level of ownership and follow-through; you notice what needs to get done and do it without being asked

• Experience recruiting and communicating with candidates for technical roles

• Familiarity with sourcing or scheduling tools like Ashby, Noon, or Google Calendars
