Human Resources Generalist - Payroll/Recruitment (Full Time)

We're hiring an HR Associate to help run the systems and operational side of People Operations at CEA. You'll own the processes that move people into, through, and out of the organisation: onboarding, contracts, expenses, payroll inputs, state and city tax filings, and the HR systems that connect them. You'll have real ownership of how these processes work, and the role includes projects to improve them with automation and AI. This position reports to Keighly Baron, HR Manager.
We're working to build a flourishing future by applying evidence, reason, and compassion to challenges like global poverty, animal suffering, and existential risks.
Our work centers on growing and supporting a global community of people who rigorously analyze where they can do the most good and take action on those insights. We had significant success in 2025, building momentum within CEA. In 2026, we've maintained ambitious momentum while building the foundations for a step-change in the wider EA ecosystem's growth trajectory from 2027 onwards.
About the People Operations team
People Operations at CEA is a small team that handles the full employee lifecycle for a distributed, international staff. The team covers compensation and benchmarking, international employment compliance, payroll and benefits administration, onboarding, employee relations, and policy. You'll work most closely with the HR Manager and the People Operations Specialist, and with colleagues in Business Operations, Finance, and Legal.
You'll also own projects: rebuilding the onboarding and offboarding workflow, building an HR metrics dashboard and a compliance calendar, and using AI to speed up drafting and routine requests.
We expect the role to be roughly half operations, a quarter systems and process projects, and a quarter onboarding, handbook, and employee experience. Early on you'll work with review before anything goes out (contracts, tax filings, payroll inputs). As you continue to onboard, that review loosens, and after probation you will move to fully owning payroll.

Coordinate pre-clearance checks: run the process, collect documents, and track status against criteria set by the HR Manager.
Collect and validate payroll inputs for the US, UK, and Deel before the People Operations Specialist runs and approves payroll. After probation, take on full ownership of the process.

Operations experience.
2+ years of experience in operations, HR operations, people operations, or a similar role. You'll handle payroll inputs, tax filings, and employee records, where errors cost money or create compliance risk.
You learn new tools quickly and have worked with HRIS, payroll, or similar platforms. Interest in HR.
You have a basic understanding of HR and want to learn employment compliance, benefits, and payroll, and are excited to continue developing.
You use AI in your own work and are interested in building workflows that save the team time.
Willingness to do administrative work.
A large part of the job is clerical, and you're excited to do it well and look for ways to automate it.
You'll write documentation, emails to new hires, and handbook content.
