Persons in these roles are expected to work from our offices in Seattle. On-site requirements vary based on position and team. If you have questions about on-site work arrangements for this role, please ask your recruiter. Our base salary range is $89,500 - $134,000 and in addition we have generous bonus plans to provide a competitive compensation package.  Who You Are: You are a meticulous, solution-oriented payroll professional who takes genuine pride in work that's invisible when it's done right. You know that payroll is a trust function at its core — every person at the organization is counting on you to be accurate, on time, every cycle — and you treat that responsibility with the seriousness it deserves. You're a process builder, not just a process runner. You get a little thrill out of replacing a manual step with a well-configured integration, and you're curious about how AI tools can take even more repetitive work off your plate. You're comfortable operating with a high degree of autonomy across a complex footprint — multiple states, multiple countries, multiple systems — without losing the details that matter. You communicate proactively, ask clarifying questions early, and follow through without needing to be reminded. When plans change at the last minute — because they will — you stay calm, set realistic expectations, and find the workable path forward. Most importantly, you understand that this role is part of something larger. Ai2's researchers are building breakthrough AI to solve the world's biggest problems — and none of that happens without a team that's paid accurately, on time, and without ever having to think about it. That's the quiet foundation you provide. Who We Are:  Ai2 is a Seattle-based nonprofit AI research institute founded in 2014 by the late Paul Allen. Our mission is to build breakthrough AI to solve the world's biggest problems. We develop foundational AI research and innovation to deliver real-world impact through large-scale open models, data, robotics, conservation, and beyond. The Finance team keeps Ai2 running so our researchers can focus on the science. We're a high-functioning, collaborative group that runs on transparency and proactive communication — we'd rather over-share than let a teammate get surprised. We celebrate process improvements the way other teams celebrate launches, we work with a large amount of autonomy and trust, and we partner daily with People Operations to take care of the 200+ people who work here. You'll be joining us at an exciting time as we modernize our payroll operations and build AI-augmented workflows into our finance processes. Your Next Challenge: The Payroll Lead owns end-to-end payroll for our distributed workforce: multi-state US payroll spanning up to 20 states, plus a small group of international and US employees paid through our Employer of Record (EOR) partners in 5–10 countries. You'll work closely with the Sr Manager of Payroll & Benefits and partners in People Operations and Finance, with broad day-to-day autonomy over payroll execution, systems, and process improvement. This role has been deliberately scoped with room to grow. There is a path toward increased responsibility for someone who demonstrates ownership of the function and drives it forward. There are also greenfield projects waiting for you, like AI-assisted payroll dashboards and data analysis work that we've never had the bandwidth to build. If you want to build broad, modern payroll expertise (multi-state, global EOR, systems integration, automation) at a mission-driven organization, this is that role. Payroll Execution Own end-to-end processing of biweekly multi-state US payroll (up to 20 states), including tax withholding, SUTA rates, and local jurisdiction compliance. Manage international payroll for employees in 5–10 countries via EOR partners, including onboarding coordination, invoice reconciliation
