GiveWell’s mission is to help people in need as much as we can by researching the most cost‑effective ways to save and improve lives, sharing our work openly, and directing donations to the programs we believe will do the most good. Our work, which focuses on global health and well-being, is funded by tens of thousands of donors who rely on our research to inform their giving. We’ve grown from directing $1.5 million in 2010 to directing more than $400 million in 2025. We anticipate our total grantmaking is likely to approach or even exceed $1 billion this year, and we are working toward a future that could be several times that scale. Through years of deliberate groundwork, we’ve been growing our research capacity and scope in order to direct substantially more funding to the most impactful opportunities we can find. Summary GiveWell is seeking exceptional Researchers to help direct hundreds of millions of dollars annually to the most cost-effective global health and poverty alleviation programs. You’ll have an outsized influence on our funding decisions and help us save and improve lives on a global scale. You’ll execute ambitious research agendas, answer complex questions, and inform high-impact grantmaking decisions by combining rigorous evidence review, cost-effectiveness modeling, and thoughtful judgment. Researchers will have the opportunity to develop into Senior Researcher or Senior Program Officer roles, leading research agendas or owning complex grantmaking portfolios. We’re open to a wide variety of professional development options depending on your preferences and our needs. The role You’ll join a small grantmaking team to execute ambitious research agendas, sifting through the countless questions we could try to answer and honing in on those that matter most. Your decisions will inform the allocation of hundreds of millions of dollars to dozens of grantees. Your practical work will combine empirical evidence review, cost-effectiveness modeling, discussions with subject matter experts, and developing your own judgment. In the course of your work, you might approach questions like these: What should we believe about the impacts of improved water quality on all-cause mortality? What is the impact of building footbridges in rural communities? How can we model the general equilibrium effects of cash transfers? How should we prioritize programs that reduce poverty relative to programs that reduce deaths? How should we think about the opportunity cost of other actors’ contributions to programs we fund? How should we account for high levels of uncertainty in our cost-effectiveness estimates? How do we use effects from trials conducted 30 to 40 years ago to predict impacts today? Responsibilities include: Analyzing interventions (e.g., vaccine demand generation, vitamin A supplementation, seasonal malaria chemoprevention) at various levels of depth to refine our view about the cost-effectiveness of a particular intervention and recommend either deprioritization or further work. Researchers review existing empirical evidence about intervention impacts, build models, speak with subject matter experts about particular interventions, and use their judgment to come up with a bottom line. Examples of this work are available on our intervention reports page . Building cost-effectiveness models to estimate the costs and benefits of a particular intervention. These models take into account a wide variety of considerations, including: one's prior estimate for an intervention's impact, the strength of the evidence, the size of the effects, the similarity between the context in which an intervention was studied and will be implemented, negative and/or offsetting effects, and how funding this intervention would affect decisions by other actors (e.g., local government, donor governments).
