Software Engineer

We're hiring a Software Engineer to join a growing team building products that reach hundreds of thousands of people thinking about how to do the most good. This is an individual contributor role on our Online Team, and will be responsible for prioritizing and implementing impactful technical work at CEA. This position reports to the incoming Head of Digital Product. You will collaborate closely with our Senior Software Engineer, Senior Product Designer, and EA Forum Product Lead, along with other teams at CEA as needed. We’re aiming to hire a mid-level software engineer, but we would consider hiring at the senior level for the right candidate. ABOUT CEA The Centre for Effective Altruism (CEA) stewards the movement of people putting effective altruism principles into practice to solve the world's most pressing problems. 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. Current strategic priorities https://forum.effectivealtruism.org/posts/QkE35oTsasMn37o7R/stewardship-cea-s-2025-26-strategy-to-reach-and-raise-ea-s-1 include increasing understanding of effective altruism and its principles, growing the number of people who are motivated by EA principles to take significant action to address pressing problems, and diversifying funding sources for high-impact work. We had significant success in 2025, building momentum within CEA. Our headcount grew from 42 to 66 core staff. Participation in our programs (e.g., events, courses, groups) grew by 20-25% year over year. We merged https://forum.effectivealtruism.org/posts/BLvTcMMEQGFYsh6Jw/ea-funds-and-cea-are-merging with EA Funds https://funds.effectivealtruism.org/ and are rapidly scaling up our capacity for grantmaking and associated fundraising: our first Fund staffed with full-time employees (EA Animal Welfare Fund https://funds.effectivealtruism.org/funds/animal-welfare), raised almost as much as the previous three years combined. In 2026, we’ve maintained ambitious momentum https://forum.effectivealtruism.org/posts/Dy4iGHbAkKAQ4t2Dw/building-sustainable-momentum-progress-report-on-cea-s-2025 while laying the foundations for a step-change in the wider EA ecosystem’s growth trajectory from 2027 onwards. ABOUT THE ONLINE TEAM The Online Team is a small, fast-paced tech and content team with the expertise to build and run web products that help support and grow the number of people engaging with and applying EA principles to their careers, research, and donations. We own and operate the EA Forum https://forum.effectivealtruism.org/, and provide critical design and engineering capacity for other CEA projects such as the EA Newsletter https://www.effectivealtruism.org/ea-newsletter-archives, the EA Opportunities Board https://www.effectivealtruism.org/opportunities, and our courses https://www.effectivealtruism.org/courses. Over the last few years we’ve also redesigned and rebuilt effectivealtruism.org http://effectivealtruism.org, funds.effectivealtruism.org http://funds.effectivealtruism.org, and centreforeffectivealtruism.org http://centreforeffectivealtruism.org. The EA Forum in particular is one of the EA community building institutions with the widest reach, serving 700K annual visitors. As AI capabilities improve, we’re also exploring how integrating AI into CEA’s online product portfolio and internal tooling can help us have more impact. Our team currently consists of Ollie Etherington https://github.com/oetherington, Senior Software Engineer, Agnes Stenlund https://www.linkedin.com/in/ag
