Job description

About the role Constellation works with the individuals and organizations trying to make sure AI goes well for humanity. That only happens if we're running well internally, and a well-run Constellation means more capacity, capability, and coordination across the AI safety ecosystem. We're looking for a People Operations Specialist to join our People team. The people who thrive here have strong judgment in ambiguous situations, know how to prioritize without being told, and are as comfortable designing a process as running one. You won't just be maintaining the People function — you'll be shaping it, and acting as a thought partner on how it should evolve. Key responsibilities Core People Operations • Own end-to-end onboarding and offboarding, including continuously improving the experience as the org evolves. • Own and improve our HRIS, including identifying gaps, managing integrations, and ensuring data integrity. • Lead benefits administration and serve as the primary point of contact for employee questions and vendor relationships. • Take ownership of compliance, proactively identifying risk and driving resolution rather than flagging up. • Design and maintain People Ops policies, programs, and internal resources — and build new ones from scratch as the org's needs change. • Make prioritization calls independently and communicate tradeoffs clearly to leadership Immigration & Legal Administration • Own immigration case management end-to-end, coordinating with outside counsel and keeping employees informed throughout. • Exercise judgment on process and timeline questions, escalating to counsel only when genuinely necessary. • Own contract and compliance administration, including identifying gaps in tracking or policy and closing them. Recruiting & Talent Operations Support • Run recruiting operations independently when needed, including scheduling, candidate communications, and onsite coordination. • Own ATS hygiene and recruiting data, and identify improvements to how the function operates. • Help shape the candidate experience, not just execute it. Skills & experience • Meaningful experience in People Operations or HR, with a track record of owning complex processes and programs end-to-end. • Strong judgment in ambiguous or sensitive situations; you make good calls when there's no playbook and people trust you with things that matter. • Highly organized with meticulous attention to detail; you notice what others miss and follow through reliably. • A self-starter who takes initiative, communicates with transparency, and is intellectually curious about the work and the mission. • Strong written and verbal communication skills, with warmth and professionalism in every employee and candidate interaction. • Comfortable designing systems and policies from scratch, not just maintaining existing ones. • Solid familiarity with HRIS systems, ATS platforms, or similar tools. • Some experience managing immigration cases or complex compliance matters. Nice-to-Have • Experience designing or restructuring People Ops processes and systems. • Exposure to multi-state or multi-country employment compliance. • Experience administering an HRIS, e.g. Rippling. You might be a good fit if you: • Care about AI safety and want your work to have a real multiplier effect on the ecosystem. • Are energized by ambiguity rather than slowed down by it. • Hold yourself to a high standard, especially when no one is watching. • Like figuring out what the right thing to do is, not just being told what to do.
