Program Officer

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 Program Officers to help us direct hundreds of millions of dollars annually to the most cost-effective global health and poverty alleviation programs. As part of our lean research team, you will have an outsized influence on our funding decisions and help us save and improve lives on a global scale.

You'll own grant investigations and help manage a portfolio of grants, evaluating the best funding opportunities and helping shape new ones. You will answer hard questions and make funding recommendations by combining rigorous evidence review, cost-effectiveness modeling, grantee relationships, and thoughtful judgment.

Update: We'll close this posting on September 11, 2026.

The role

You'll join a small grantmaking team to own grant investigations and help manage a portfolio of grants, sifting through the many opportunities we could fund and honing in on those that matter most—and, when the best opportunity doesn't yet exist, helping bring a better one into being. 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, grantee engagement, ground-truthing of how programs are delivered, discussions with subject matter experts, and developing your own judgment. In the course of your work, you might approach questions like these:

Should we make this grant, and how should we structure it (e.g., conditions, milestones, or gates)? When a promising intervention has no clear implementer, what would it take to help one get off the ground? Is this grant on track, and if not, why? Do a grantee's reported outputs reflect real coverage, quality, and adherence to evidence-based practices on the ground? What should we believe about the cost-effectiveness of an intervention in our portfolio, and what would change our minds? How should we monitor a grant's progress, and what would tell us to course-correct? How should we account for high levels of uncertainty in our cost-effectiveness estimates? How should we weigh empirical evidence against qualitative factors, like a grantee's organizational track record?

Responsibilities include:

Investigating and recommending grants. We receive and solicit requests for funding on an ongoing basis, and you'll own investigations into these opportunities from scoping through recommendation. You'll discuss each opportunity with the potential grantee, consider its plans and assess the likelihood of achieving them, estimate the cost-effectiveness of the grant and forecast its likelihood of success, and recommend how to structure it (e.g., whether to include conditions, milestones, or gates). When necessary, you'll solicit feedback from outside experts (e.g., academics, government officials) about the opportunity. Managing a portfolio of grants. Once a grant is made, you'll maintain a current view of whether it's on track and why. This includes collaborating with grantees to assess whether reported outputs reflect real coverage, quality, and adherence to evidence-based practices, and ground-truthing how programs are delivered—through monitoring data, site visits, and conversations with field staff—so we can learn and course-correct over the life of the grant. 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 interventions in your portfolio and recommend either deprioritization or further work. You'll review existing empirical evidence about intervention impacts, build models, speak with subject matter experts about particular interventions, and use your 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). See more on our page about our cost-effectiveness models . Building relationships relevant to our work , for example with grantees and program staff at organizations we are funding or considering for funding, academics who specialize in interventions we are reviewing (e.g., malaria, malnutrition treatment, in-line water chlorination), and program staff at other funders who are also evaluating where to allocate funds. Publishing reports and blog posts on our website. Transparency is a core value of ours and we aim to publish as much supporting information regarding our conclusions as we can. Program Officers write up findings and reasoning for publication on our website or summarize key points from their work in blog posts .

What is career development like?

After gaining experience on the team, Program Officers have the opportunity to develop into Senior Program Officers, who own high-impact, cost-effective grantmaking portfolios by deepening their expertise, growing their networks, and understanding the broader context within a specific grantmaking area. Senior Program Officers may then pursue a few pathways for career development based on their preferences and GiveWell's needs. Some choose to deepen and expand their portfolios as individual contributors, while others take on people management responsibilities. Another potential pathway is to move into the research track as a Researcher, focusing on leading research agendas rather than owning a grantmaking portfolio.

Team structure

Our research department is currently organized into eight teams:

Five of the teams (Water, Livelihoods, Nutrition, Malaria, and Vaccines) focus on specific areas of grantmaking. The New Areas team focuses on interventions in domains that are new to GiveWell. The Cross-Cutting team focuses on methodological issues, research quality, and other big-picture concerns that cut across all of our research work. The Commons team provides generalized research support to each of the other teams, including landscaping research, vetting, and publishing.

In some cases, we’ll make offers for specific subteam placements. In others, we’ll offer the opportunity to complete a few rotations on different teams over several months before settling on a final subteam placement. We’ll discuss placement details in the final stages of the hiring process.

Team values

We think our research team has unique qualities:

We care deeply and centrally about finding and sharing truth. Truth-seeking is one of our core values . We post our mistakes and we prize our team members who keep our culture of free-flowing feedback strong.

We are independent. We focus 100% on finding the most cost-effective opportunities to save and improve lives. Our researchers assist in communicating our research findings to the public and our donors, and on occasion we provide tailored advice to ultra-high-net-worth donors who want to rely on our expertise to direct their giving—but we never ask our researchers to trade off against honesty, or to hide their real beliefs.

We don’t waste time. Once it’s clear that a particular research question is unlikely to change our bottom-line funding recommendation, we drop it as quickly as possible. We encourage our research staff to constantly re-evaluate their portfolios and only work on the highest-priority questions.

Lean research team = huge personal impact. In 2026, our research team of ~80 people is directing close to 1 billion dollars and we expect grantmaking dollars per research team member to increase in the future.

We work well together. Our research team is lean because we’re able to attract top-tier people, all of whom complete skills-based assessments before joining our staff. We maintain a high-performing, collegial culture and pay our staff accordingly.

About you

The strongest candidates will typically have around 3-5 years of professional experience, a significant portion of which was in similar or closely-related roles. Many of our Program Officers have quantitatively-oriented advanced degrees, but there's no hard academic requirement—what matters is a demonstrated ability to use empirical tools to make rigorous, evidence-based decisions, whether that comes from graduate training or hands-on experience.

We expect you will be characterized by many of the below qualities. We encourage you to apply if you would use the majority of these characteristics to describe yourself:

You are passionate about helping improve global health and alleviate global poverty as much as possible. You are highly skilled at critically analyzing and synthesizing empirical research and understanding how a body of evidence applies to real-world funding decisions. You get things done, and you'll drop what you're doing when something matters more. You drive work to conclusions, and when the evidence shifts or a higher-value opportunity appears, you're eager to pivot. You're drawn to gaps. When you see something missing—a program that should exist, an implementer worth seeding, a better way to structure a grant—you want to help make it happen, and you're comfortable taking bets under uncertainty. You are able to plan an efficient approach to exploring complicated questions, including identifying and focusing on the most decision-relevant aspects of a project. You consider the big picture, asking questions like: is this project appropriately formulated and the best use of my time? What is GiveWell getting wrong in our research? You clearly communicate what you believe and why, as well as what you are uncertain about. You ask a lot of questions, and are curious, rather than defensive, when interrogating your own or others' work. You are effective at building and managing relationships with external parties, including grantees, experts, and other funders. You are respectful, effective, and efficient in your interactions with colleagues as well as external parties.

About GiveWell

GiveWell is dedicated to finding and evaluating highly cost-effective global health and development opportunities, and we publish all the work, reasoning, and uncertainties behind our funding decisions. Our giving funds enable donors to contribute to the most impactful and cost-effective programs our researchers identify.

GiveWell is one of the world’s largest private funders of global development efforts. Trusted annually by tens of thousands of donors, GiveWell searches for highly cost-effective programs that save or improve lives the most. Since 2007, more than 150,000 donors have given over $2.6 billion through GiveWell to the most promising programs its research has identified, which we estimate will save more than 340,000 lives .

GiveWell is most well-known for recommending a small number of Top Charities , which currently support seasonal malaria chemoprevention , insecticide-treated nets , vaccine incentivization , and vitamin A supplementation . However, most of our research capacity and grantmaking is devoted to cost-effective opportunities outside of those programs .

GiveWell grants have:

Helped governments navigate changes to the funding landscape and implement high-impact health programs, like HIV/syphilis screening and treatment for pregnant people in Zambia and Cameroon. Sought to scope and scale promising interventions that don’t have clear existing implementers. We are supporting the Clinton Health Access Initiative’s Incubator to identify potentially cost-effective interventions and create programs that we would be excited to support in the future. For example, we funded a program to prevent tuberculosis among young children in Uttar Pradesh and Bihar, India, that we co-designed with CHAI through the Incubator program. Provided funding to ensure that programs that recently faced foreign aid funding cuts could continue, like healthcare support and malnutrition treatment in northern Cameroon. Funded program delivery alongside strengthened monitoring and evaluation, as in our grants to support treatment of clubfoot and to evaluate the program . Tested our assumptions and refined our understanding through further research and data collection, including improved estimates of disease burden and studies on the effect of water chlorination on mortality and the impact of a tree-planting program on farmers’ income .

We make our reasoning public and transparent so others can challenge it (sometimes we even pay people to point out our errors ). We go to unusual lengths to check our assumptions and assess our impact, including funding research to address our uncertainties and gathering independent monitoring and evaluation data about the programs we support. We change our minds when the evidence demands it. For more about GiveWell, listen to Ezra Klein’s recent interview with GiveWell’s co-founder and CEO Elie Hassenfeld.
