GiveWell is an independent nonprofit research organization that makes grants to cost-effective global health and development organizations, supported by tens of thousands of individual donors. Our work is characterized by unusual levels of transparency and rigor relative to other philanthropic funders, and we were described early in our history as the "gold standard of giving."
We're hiring a Chief of Staff to Teryn Mattox, our Chief Research and Programs Officer. Teryn leads GiveWell’s research team (~75 people right now, likely 100+ by end of year) and is a senior member of GiveWell’s executive leadership team.
GiveWell is on track to direct over $1 billion in grants this year. This will make us one of the top few private funders of global health and development in the world, and represents a step change from ~$400M in 2025 grantmaking. Our best guess is that our grantmaking will reach multiple billions annually as early as 2027.
Few organizations in any sector grow from $400M to multiple billions in annual funding within a few years. We’ll be facing hard problems as we scale, including these:
Teryn is the executive responsible for steering the research team through this transition. Her Chief of Staff will work on these problems every day, with an unusual amount of access and influence. This is a senior position that sits on the Research Leadership Team, and we expect the person in it to operate as Teryn’s deputy while building a small office to support her.
Thought partner
You'll spend a lot of time with Teryn, joining meetings, 1:1s, and communicating asynchronously. You need to know what Teryn knows so you can push back on her thinking and help her make better decisions.
Concretely, this could look a few ways:
Spotting problems and opportunities
You’ll spend a lot of time building context and relationships with team members by reading internal documents, joining meetings, and attending in-person retreats. You will develop substantive opinions on what’s going on in all departments (not just research), and what we should be doing differently across the board. You will also identify and execute fixes. Those fixes will likely be complicated cross-functional projects that include external and internal communications, publishing, recruiting, financial planning, and more.
Building Teryn’s personal office
Teryn expects to build out a small team supporting her over the next year or two, likely including a deputy chief of staff and administrative and project management capacity. You'll help design this office, hire into it, and likely manage the team. This is a chance to build something from scratch inside an organization that is scaling quickly.
Unsticking complicated projects
There are a number of projects that are on Teryn’s plate because there is no other obvious owner or because they require executive-level coordination across teams. You will own some of these projects, and in other cases support Teryn in making them go more quickly. Here are some live examples:
This job requires deep immersion in GiveWell's work, and we expect it will take a few months before you can give excellent advice on arbitrary problems. After six months to a year, success looks like:
This is a senior role. We expect strong candidates will typically have 10 or more years of work experience, including time operating at or near the executive level of a complex organization. That might mean serving as chief of staff to a CEO, holding a C-level role, being a partner or senior leader at a consulting firm, or leading a functional team through rapid scale. Experience in global health, development, or philanthropy is valuable but not required. We care more about demonstrated capability than about any particular resume; if your background is unusual but you're exceptional at this kind of work, we want to hear from you.
The qualities we care most about:
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:
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.
We don’t want to miss candidates that could do great things at GiveWell. Practically, that means a GiveWell staff member reviews every application carefully, considering the whole picture of your background and potential. If you’re on the fence about applying because you meet some but not 100% of our preferred qualifications (some studies suggest this hesitation is especially common for women and people of color), we encourage you to apply anyway.

Beyond the requirements of those laws, we value our team’s diversity in all respects, and we desire to maintain a work environment free of harassment or discrimination—we want our team members to thrive at GiveWell.
