RadixArk builds large-scale inference and training systems for the entire AI community, making frontier-level AI infrastructure open and accessible. Backed by Accel.
About the role
We're looking for a hands-on Talent Operations Specialist to build and run the machinery behind talent and people ops as we scale. This isn't a traditional HR generalist role - it's for someone who treats recruiting and people ops like an engineering challenge: we don't just 'use' tools, we build AI-augmented workflows, automate the manual, and engineer our people & talent infrastructure for scale.
What they're looking for
- On-site or hybrid presence preferred
- Experience in talent ops, people ops, management consulting, or other high-intensity operational roles
- API/MCP experience, comfortable with ATS integrations and automation
- Experience with recruiting or people technology (Ashby, Rippling, Greenhouse, Workday, GoodTime, Modernloop)
- You've supported or run programs across multiple regions, working through regional differences in compliance, process, and stakeholder needs
- You write and speak clearly, whether the audience is a hiring manager, a vendor, or leadership

You'll straddle recruiting ops and people ops, work directly with our existing team, and own the day-to-day execution that keeps our ATS and HRIS infrastructure fast, clean, and scalable. We move fast and put in long hours because we're building the infrastructure for a small team to operate like a much larger one - if that trade-off excites you rather than drains you, you'll fit in here.
- Own interview coordination end to end: schedule and manage complex, multi-stakeholder interviews across formats and time zones.
- Build AI into coordination and reporting workflows so a small team can run at scale.
- Deliver a white-glove candidate experience as the primary point of contact through the interview process, responsive and clear at every touchpoint.
- Maintain data integrity: own...
