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. We’re hiring a Senior Communications Officer, Strategic Communications to lead GiveWell’s development of messaging and narratives that explain its work across different audiences and contexts. You will translate the organization’s increasingly diverse and complex work into clear, accurate communications and lead major initiatives that require close coordination across GiveWell. This role reports to Steven Profaizer, our Vice President of Communications, and will lead a small and growing team. This is one of three new communications leadership roles, alongside a Senior Communications Officer, Media & Public Affairs and a Senior Communications Officer, Editorial & Production. About the role Both our research and impact are expanding. Last year, we directed more than $400 million t Please mention the word **REVOLUTIONIZE** and tag RMTUxLjgwLjE0Ni43Mw== when applying to show you read the job post completely (#RMTUxLjgwLjE0Ni43Mw==).

The Problem 36 million businesses in America need insurance—it's not optional. 77% are underinsured. 40% have no coverage at all. The distribution system failed them: too slow, too opaque, too confusing. Over 90% of commercial insurance is still human-led. We're building the inverse: 90%+ AI-led, pushing toward the higher 90s. Not by patching legacy workflows—by building AI that makes humans more effective, improves the customer experience, and eliminates friction at every step. We're adding ~1,000 customers per month. We've grown 100x since last year. We're looking to do even more this year—and that's why we're hiring. You'll build the team and the systems the rest of engineering depends on. When they compound, everyone gets faster. The Thesis Harper runs 200+ services across Railway and AWS. We orchestrate N parallel agentic workloads. Our AI systems make thousands of decisions a day, and every decision needs to be traceable, evaluated, and cheaper to run tomorrow than it is today. The infrastructure underneath all of that is the difference between a company that scales and one that stalls. Great platform engineering here isn't invisible—it's the reason product ships fast. When observability catches a silent failure before a customer does. When a pooling layer makes connection exhaustion a non-issue. When developer velocity doubles because someone built the tool nobody knew they needed. That leverage compounds across every other engineer on the team. The Role This role is open both to an experienced EM and to someone on the path to becoming an EM who doesn't yet have significant management experience—we're happy to bring that person on and support the transition. This is a team that still needs to be built. We have 2 people in it today, and we believe this area needs significant investment at Harper. The role owns three things: infrastructure (cloud, third-party vendors, and everything surrounding it), developer productivity (making sure we're genuinely…
