Recruiter

About the role

About the Role This is a rare opportunity to own recruiting at a lean, high-caliber AI infrastructure startup — a team intentionally kept small so that every single hire genuinely shapes the company's direction. You'll work directly with founders and world-class researchers, partnering closely on both technical and go-to-market roles in a tight-knit, in-person culture in San Francisco. The company operates at the frontier of reinforcement learning (RL) and AI evaluation , building infrastructure that enables AI labs and businesses to create, manage, and scale RL environments. You'll need to get fluent enough in the product to pitch it credibly to top engineering talent. What You'll Do Own full-cycle recruiting across both technical (engineering, ML/AI) and GTM roles. Build and continuously optimize recruiting operations and tooling — automate wherever possible. Partner directly with founders and team leads to define role requirements, evaluation criteria, and interview processes. Develop a strong understanding of the product to engage credibly with technical candidates. Source exceptional candidates through high-signal and unconventional channels. Screen candidates for technical competence, product intuition, and culture fit — going beyond resumes to portfolios and projects. Support new hire onboarding and ramp-up. Help define and run performance review processes, leveling frameworks, and feedback systems. What We're Looking For Required: Proven experience hiring across engineering, product, and GTM functions. Comfort evaluating candidates via portfolios, projects, and work samples — not just traditional resumes. Ability to understand and communicate technical concepts credibly with engineering candidates. Strong organizational skills with the ability to manage multiple open roles and pipelines simultaneously. Sharp instincts for talent quality and maintaining a high hiring bar. Prior early-stage startup experience; comfortable operating independently in fast-moving environments. A track record of creative, non-traditional sourcing strategies. Nice to Have: Hands-on experience with recruiting tools such as Ashby , Juicebox , and Clay . Experience with AI-assisted workflow automation and "vibe coding" to build recruiting tooling. Exposure to or direct ownership of people operations and HR functions. A history of successfully evaluating and championing non-traditional candidate profiles. Compensation & Benefits Salary: $100,000 – $150,000 USD annually Visa sponsorship is available Location This role is on-site in San Francisco, CA . The team values in-person collaboration and the energy of working closely together — remote or hybrid arrangements are not available for this position.
