Senior Program Associate/Associate Program Officer – Lead Exposure Action Fund

About Coefficient Giving

Coefficient Giving (formerly Open Philanthropy) is a philanthropic funder and advisor. Since 2014, we've directed over $4 billion in grants as part of our mission to help others as much as we can with the resources available to us. We work with a range of donors who share our commitment to cost-effective, high-impact giving. Our current funds include Science and Global Health R&D, Navigating Transformative Artificial Intelligence, Abundance & Growth, Farm Animal Welfare, Biosecurity & Pandemic Preparedness, and more. In 2025, we recommended more than $1 billion to high-impact causes.

We’re proud of our track record:

• Our grants to evidence-backed global health programs have saved over 100,000 lives, and our farm animal welfare grants have improved the lives of over 3 billion animals.

• We supported the late stage clinical trials for the R21 malaria vaccine, now being scaled to protect millions of kids globally.

• We were the earliest major funder of the YIMBY movement to build more housing. Our grantees have led the charge on major wins like City of Yes in New York, and SB 79 in California, which will enable hundreds of thousands of new housing units.

• We jump-started the field of AI safety and security and have played a vital role in addressing other existential threats such as mirror bacteria.

About the Lead Exposure Action Fund

The Lead Exposure Action Fund (LEAF) addresses one of the world's most neglected public health crises. Lead exposure causes lasting harm to nearly every organ system. In children, it lowers IQ, worsens learning outcomes, and leads to long-term health and economic losses. An estimated 1 billion children have blood lead levels above the WHO's threshold for action. Despite this, funding to tackle lead remains a fraction of what is spent on similarly serious global health challenges.

In its first year, LEAF's grants more than tripled total annual global philanthropic funding for lead mitigation. These efforts helped catalyze government action, major philanthropic commitments, multilateral initiatives (including the Partnership for a Lead-Free Future), and the scaling of highly cost-effective lead organizations (see our public grant database for examples, including LEEP and Stanford's Project Unleaded). LEAF focuses its support on the strongest opportunities for cost-effective impact, funding grantees to identify and eliminate major sources of lead exposure across low- and middle-income countries.

About the role

This is an ambitious moment for global lead work. New funders have entered the space, a major wave of lead exposure measurement and source identification is underway across many countries, and the range of implementers working on lead has expanded significantly. We expect that opportunities to fund cost-effective interventions will continue to proliferate, and LEAF needs to be well-positioned to identify, assess, and act on them.

We are open to hiring either at the Senior Program Associate or Associate Program Officer level. At the Senior Program Associate level, you would contribute across LEAF's grant investigations and research, working closely with the team. At the Associate Program Officer level, you would take the lead on a defined area of the portfolio (with room to expand it over time), forming and maintaining your own grantee relationships. In both cases, you would work closely with James Hu, Senior Program Associate, and report to Tom Hird, Senior Program Officer.

Your responsibilities would include:

• Contributing directly to grantmaking across the full cycle, from early-stage sourcing and impact evaluation (using impact calculations) through to drafting detailed grant recommendations for funding decisions

• Assessing opportunities as new measurement data, policy developments, and partner capacity create openings for action; building cost-effectiveness models to determine which opportunities clear our bar for funding

• Contributing to strategy for your area of the portfolio based on your own analysis of expected benefits, and updating it as conditions evolve

• Building and maintaining relationships with grantees, government counterparts, multilateral partners, and other funders

• Representing Coefficient Giving and LEAF at external meetings, conferences, and field visits

We expect this role to work on grantmaking across several areas of LEAF's sub-strategies and across a range of geographies. For examples of geographies we've worked in, see our featured grants here.

The work requires comfort with quantitative analysis and cost-effectiveness reasoning. We are particularly interested in this role taking on a growing area of country-level work: assessing where conditions are right for action, building relationships, and helping to prepare for new interventions as the evidence base develops. This would likely include travel to priority countries to meet implementing partners and government counterparts, and coordinate with other funders on shared priorities. The exact nature of the role will depend on the person we hire, and there is scope to shape it around complementary strengths.

Who might be a good fit

For both the Senior Program Associate (SPA) and Associate Program Officer (APO) levels, we’re looking for people who:

• Bring excellent written and oral communication skills, especially the ability to clearly explain your views, including when operating with incomplete information

• Have strong analytical and quantitative skills, including comfort with modelling cost-effectiveness and grounding estimates in imperfect evidence

• Can quickly grasp new contexts, exercise good judgment about which potential grant opportunities to evaluate, and draft clear recommendations with strong reasoning transparency

• Bring strong interpersonal skills and can build productive relationships with ideologically and culturally diverse grantees, government counterparts, and other funders

• Have a track record of effectiveness across more than one field, sector, or role

This role carries the potential for significant autonomy, including owning investigations end-to-end and building your own grantee relationships. You'd also be working closely with a small, tight team, collaborating on strategy, pressure-testing each other's reasoning, and coordinating across a portfolio spanning many countries and partners.

Experience in the following areas would be nice-to-have, but is not required for the Senior Program Associate role, and would be a meaningful factor for the Associate Program Officer role:

• Lead pollution, environmental pollutants, or related health areas

• Implementation-focused organizations

• Familiarity with South Asia (e.g. India, Pakistan, Bangladesh) and Sub-Saharan Africa (e.g. Nigeria)

• Industry-facing experience (supply chains, market dynamics, private sector engagement)

There is no such thing as a "perfect" candidate. If you are on the fence about applying because you are unsure whether you are qualified, we strongly encourage you to apply.

By default, we will consider all candidates for the Senior Program Associate role. If you meet the Associate Program Officer criteria and would like to be considered only for that role, please note this in your application.

Role details & benefits

• Compensation:

  • The baseline compensation for the Senior Program Associate role is $129,498.55, which would be distributed as a base salary of $112,607.43 and an unconditional 401(k) grant of $16,891.12 for U.S. hires. All compensation will be distributed in the form of take-home salary for internationally-based hires.

  • The baseline compensation for the Associate Program Officer role is $178,930.31, which would be distributed as a base salary of $155,591.57 and an unconditional 401(k) grant of $23,338.74 for U.S. hires. All compensation will be distributed in the form of take-home salary for internationally-based hires.

  • These compensation figures assume a remote location. There would be geographic adjustments upwards for candidates based in the San Francisco Bay Area or Washington, D.C.

• Time zones and location: Both LEAF team members are currently based in the UK. This role is remote and open to candidates in other locations, but you would need to be available during U.K. business hours for 2–3 hours on most working days. Some international travel should be expected.

  • If you feel you’re a strong fit for this role but are concerned that location could be a barrier, we still strongly encourage you to apply. We’re open to flexibility on location for the right candidate.

  • We are happy to consider sponsoring U.S. work authorization. However, we don’t control who is and isn’t eligible for a visa and we can’t guarantee visa approval.

• Benefits: Our benefits package includes:

  • Excellent health insurance (we cover 100% of premiums within the U.S. for you and any eligible dependents) and an employer-funded Health Reimbursement Arrangement for certain other personal health expenses.

  • Dental, vision, and life insurance for you and your family.

  • Four weeks of PTO recommended per year.

  • Four months of fully paid family leave.

  • A generous and flexible expense policy — we encourage staff to expense the ergonomic equipment, software, and other services that they need to stay healthy and productive. This policy also includes a productivity benefit, which provides a set amount for staff to expense items that enhance their productivity.

  • A continual learning policy that encourages staff to spend time on professional development with related expenses covered.

  • Support for remote work — we'll cover a remote workspace outside your home if you need one, or connect you with a Coefficient Giving coworking hub in your city. We currently have offices in San Francisco and Washington D.C., and multiple staff working from several other cities in the U.S. and elsewhere.

  • We can't always provide every benefit we offer U.S. staff to international hires, but we're working on it (and will usually provide cash equivalents of any benefits we can't offer in your country).

• Start date: We're aiming to make an offer by early June and would like a candidate to start soon after, though we're open to flexibility for the right person.

We aim to employ people with many different experiences, perspectives, and backgrounds who share our passion for accomplishing as much good as we can. We are committed to creating an environment where all employees have the opportunity to succeed, and we do not discriminate based on race, religion, color, national origin, gender, sexual orientation, or any other legally protected status.
