GiveWell is a research organization that identifies and funds cost-effective giving opportunities, focusing on global health and well-being. Our work 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.
GiveWell is seeking a Senior Malaria Researcher to help us direct hundreds of millions of dollars annually (we directed ~$250 million in 2024) to the most cost-effective malaria prevention programs that we can find. You will have an outsized influence on our funding decisions and help us save and improve lives on a global scale.
Our malaria grantmaking has previously consisted of vector control (distribution of insecticide-treated nets), seasonal and perennial malaria chemoprevention, and malaria vaccines. In the future, we may expand into new areas like case management and therapeutics.
As a Senior Malaria Researcher, you’ll create and lead ambitious research agendas related to our portfolios of work and answer complex questions that will inform GiveWell’s grantmaking decisions. The researchers on our team combine rigorous evidence review, cost-effectiveness modeling, and thoughtful judgment.
We’re open to a wide variety of professional development pathways depending on your preferences and our needs.
You will be joining a small grantmaking team to contribute to our ambitious research agenda on malaria. You’ll sift through the countless questions we could try to answer, and honing in on those that matter most. You’ll also communicate externally about your work and mentor and advise other researchers on the team.
You will shape a research agenda that brings rigor and creativity to the thorniest questions the GiveWell malaria team faces. Your work will combine empirical evidence review and critical synthesis, cost-effectiveness modeling, discussions with subject matter experts, understanding of the broader context, and your own judgment. In the course of your work, you might approach questions like these:
