Researcher

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). See more on our page about our cost-effectiveness models.
• Reviewing specific grantmaking opportunities. We receive and solicit requests for funding on an ongoing basis. Researchers investigate each of these opportunities to determine whether or not they should receive funding. Reviewers discuss each grant opportunity with the applying organization, consider its plans and assess the likelihood it will achieve them, estimate the cost-effectiveness of a grant and forecast its likelihood of success. When necessary, they solicit feedback from outside experts (e.g., academics, government officials) about the opportunity.
• Tackle thorny research questions with creative approaches. We often need to answer questions that don’t have clear answers in published academic journals or other data sources (see some examples above), but which nevertheless matter significantly to our bottom-line funding decisions. You’ll come up with creative approaches to answer these questions, and your work will often influence the funding decisions of many of GiveWell’s research subteams.
• Building relationships with experts relevant to our work, for example, academics who specialize in interventions we are reviewing (e.g., malaria, malnutrition treatment, in-line water chlorination), leaders and program staff at organizations we are considering for funding, and program staff at foundations 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. Researchers write up our 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, Researchers have the opportunity to develop into Senior Researchers, who lead the development of our research agendas. Senior Researchers may then pursue a few pathways for career development based on their preferences and GiveWell’s needs. Some choose to develop wider and more autonomous research agendas as individual contributors, while others take on people management responsibilities. Another potential pathway is to transition into a Program Officer or Senior Program Officer position, in which you’d own a high-impact, cost-effective grantmaking portfolios by deepening your expertise, growing your networks, and understanding the broader context within a specific grantmaking area. Senior Program Officers think through questions like:

• How should we balance exploring and seeding new, smaller opportunities with funding cost-effective opportunities at scale today?
• How can we triangulate empirical evidence against expert opinion on other qualitative features, like organizational track record?
• What is research we can fund today that could substantially impact our grantmaking five years from now?
• How much uncertainty are we willing to accept before making a grant? What key research questions do we need to answer before making a grant, and which ones can we deprioritize or answer later?

Team structure

Our research department has ~60 people, and 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 most cases, we hire Researchers without knowing which subteam they’ll eventually sit on. We aim to expose new researchers to different types of work and parts of the team over several months to inform their eventual subteam placement. (We might settle on a subteam more quickly if new hires bring specific, specialized expertise.)

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.

Details

• Team: You'll join one of our grantmaking teams (see our org structure here) and report to a Senior Researcher or Senior Program Officer.
• Compensation:
• NYC or the San Francisco Bay Area: $220,000
• All other U.S. locations: $200,000
• International: Similar to the “all other U.S. locations” salary, based on historical exchange rates and delivered in locally-denominated currency.
• Countries we can hire from: GiveWell is a remote-first organization. However, for the time being, we can only hire within a select number of countries (US, UK, Canada, Switzerland, and Germany). To be considered for a role with GiveWell, you need to already be based in one of those countries or be willing to move to one of them. We expect to expand the list of locations where we can hire over the course of 2027, and our job descriptions always reflect the current status — so we'd encourage you to check back and apply again for a role you're eligible for.
• Visa sponsorship: The US is the only country where visa sponsorship is possible for a number of roles, and it's assessed on a case by case basis. For all other countries, you need to already have work authorization, we cannot sponsor visas.
• Why we work this way: Focusing on countries where we already have tested onboarding processes lets us move candidates through hiring faster and with fewer surprises. Every additional country brings its own labor laws, EOR requirements, and new processes to work through, which slows things down for hiring teams and new colleagues alike. Concentrating our footprint keeps the experience consistent and supports GiveWell’s wider absorption capacity goals.
• Flexibility: We support and encourage flexible working, including flexible hours, working remotely, and working from the office when you choose. The majority of our staff, including senior management, work flexibly in one way or another.
• Benefits: Our benefits include:
• Fully funded health, dental, vision, and life insurance (we cover 100% of premiums within the US for you and any dependents)
• Four weeks of paid time off per year
• 16 weeks of fully paid parental leave
• Ergonomic home workstations or coworking space memberships
• Automatic contribution equal to 5% of your gross salary into your 403(b) retirement plan (for U.S. based staff)
• Travel: Research team members are sometimes required to attend international site visits and conferences (on average 1-2 per year), with additional travel for those interested in traveling more. Additionally, we strongly encourage staff members to attend quarterly whole-org and department retreats to bond with other team members and complete in-person work. We'll discuss travel obligations in more detail during late stages of the hiring process, and we’ll accommodate staff who have conflicting family or other obligations.
• Start date: We’d like a candidate to start as soon as possible after receiving an offer, but we’ll offer flexibility for candidates whose personal or professional circumstances require them to moderately delay their start date.

About you

Our typical hire for this role has a master's degree in a quantitative field (e.g., economics, policy, public health) with a few years of relevant experience, or a PhD in a quantitative field with limited post-graduation experience. We're willing to make exceptions for applicants who don't have advanced degrees but demonstrate equivalent depth of expertise.

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 may apply to real-world problems.
• 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 able to execute research that holds up under scrutiny from others and over time.
• You are respectful, effective, and efficient in your interactions with colleagues as well as external parties.

Other notes

• Please note that our hiring process consists of the same work trials for the following roles: Researcher, Senior Researcher, Senior Cross-Cutting Researcher, Senior Livelihoods Researcher, Senior Malaria Researcher, Senior New Areas Researcher, Senior Nutrition Researcher, Senior Vaccination Researcher, and Senior Water Researcher. If, within the last year, you applied and were rejected for one of these roles, you should hold off on applying to the other roles, unless explicitly asked to do so by a member of our team. If you're interested in all of these roles, please just apply once and note in your application that you'd like to be considered for the other roles, too.
• Please note that this role was previously titled "Senior Research Associate." The position itself remains unchanged.
• After application review, our hiring process consists of a short application exercise, two compensated work trials, and several short interviews. You can see more details about our hiring process on our FAQs page!
• You don't need to submit a cover letter with your application—we only want your resume/CV and answers to the application questions below.
• Economics PhD candidates on the job market do not need a job market paper to apply.
• We don’t offer informational calls at this stage, but please email us at with any questions not answered here!

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.
