The Foundation We are the largest nonprofit fighting poverty, disease, and inequity around the world. Founded on a simple premise: people everywhere, regardless of identity or circumstances, should have the chance to live healthy, productive lives. We believe our employees should reflect the rich diversity of the global populations we aim to serve. We provide an exceptional benefits package to employees and their families which include comprehensive medical, dental, and vision coverage with no premiums, generous paid time off, paid family leave, foundation-paid retirement contribution, regional holidays, and opportunities to engage in several employee communities. As a workplace, we're committed to creating an environment for you to thrive both personally and professionally. The Team The Institute for Disease Modeling (IDM) is an embedded research institute with the Gates Foundation. We develop, use, and share computational modeling tools, and promote quantitative decision-making to support global efforts to eradicate infectious diseases and achieve permanent improvements in the health of those most in need. The IDM team is composed of research scientists and software developers who develop and prototype computational tools to advise on global health and development policy and identify and address critical knowledge gaps. IDM is a multifaceted organization with a work environment defined by innovation and teamwork. As part of our work, we routinely collaborate with groups at the World Health Organization, UNAIDS, the Centers for Disease Control, PATH, ministries of health, as well as universities and research institutes across the globe. Your Role We are looking for a senior generalist engineer who is energized by designing and building modern AI systems agents, retrieval pipelines, evaluation harnesses, and the backend services that hold them together. You are passionate about well-architected software, you make pragmatic build-vs-buy and self-host-vs-API calls, and you reach for the simplest approach that actually solves the problem. You will work on projects with real-world impact for global public good, integrated into a collaborative, mission-driven team alongside IDM researchers and their internal and external collaborators. You will be essential in turning AI ideas into working systems agents, services, evaluations, and the connective tissue that lets a small team ship a lot. *This is a 36-month limited-term position based in Seattle, WA. Relocation will be provided. What You'll Do + Design and build agentic AI systems - multi-step workflows, tool use, and autonomous task orchestration using modern LLM frameworks - and ship them as reliable backend services. + Build and operate retrieval systems: ingestion, chunking, embeddings, vector search, and knowledge-graph-backed retrieval where it earns its keep. + Design AI evaluation pipelines and benchmarks so the team can tell whether an agent, model, or retrieval system is actually getting better - and monitor them in production. + Architect, implement, and maintain scalable backend services and APIs that other engineers, researchers, and applications build on top of. + Make senior-level architectural calls - model choice, hosting (Azure OpenAI vs. self-hosted), framework selection, and infrastructure tradeoffs - and mentor other engineers on AI application patterns. + Develop data pipelines and workflows leveraging Azure (Azure AI Foundry, Azure OpenAI, Azure AI Search, Azure Databricks) and Hugging Face. + Harden successful prototypes into production: tests, observability, cost and latency monitoring, failure handling, and documentation that let other people trust and reuse them. + Collaborate directly with researchers, analysts, and program staff to translate fuzzy domain problems into shippable systems for global health and global development. + Identify knowledge, data, or tooling gaps in the settings in which we work and propose pragmatic solutions. Your Experience + Bachelor's degree in a technical field with 5+ years building production software, or equivalent experience. Advanced degree is a plus, not required. + Strong general-purpose backend engineering: you can pick up unfamiliar code, debug across systems, and ship services that hold up in use. + Proficiency in Python, including for AI work (e.g., PyTorch, Hugging Face, or similar). + Hands-on experience building LLM-powered applications: retrieval-augmented generation (RAG), agentic workflows, tool use, and prompt engineering at production scale. + Experience designing and operating backend APIs and services in cloud environments - ideally Azure, but AWS or GCP equivalents are fine. + Experience building AI evaluations and observability - measuring quality, cost, and latency of LLM systems and acting on the results. + Hands-on experience with data pipelines and ETL, MLOps/AI Ops workflows, and cloud data services. + Experience with Git, CI/CD, containerization (Docker), infrastructure-as-code, and broader DevOps practices. + Comfort making and defending architectural tradeoffs (managed service vs. self-host, fine-tune vs. prompt, agent vs. workflow) and mentoring others through them. + Comfort working directly with researchers and non-engineers - able to translate fuzzy problems into concrete software, and to push back when the simplest answer is "we don't need to build that." + Track record of taking projects from prototype to something other people rely on. Other Attributes + Experience with vector databases, knowledge graphs, or information architecture for AI applications. + Experience with fine-tuning, distillation, or other model adaptation techniques. + Exposure to scientific, public health, geospatial, or climate-related datasets. + Engagement with the open-source AI community. + Ability to stand up lightweight interactive demos (Streamlit, Gradio) when needed to show work to non-engineering stakeholders. + Publications, patents, or other public artifacts that show depth in an area - but not required and not weighted over shipped work. **Must have unrestricted work authorization in the country where this position is located. The Foundation does not provide immigration-related sponsorship for this role. This includes direct company sponsorship and any work authorization requiring a written submission or other immigration support from the company (eg: H-1B, O-1, L-1, E, OPT, STEM-OPT, CPT, TN, J-1, etc.). The salary range for this role is $186,400 to $288,800 USD. We recognize high-wage market differences in Seattle and Washington D.C., where our offices are located. The range for this role in these locations is $203,100 to $314,900 USD. As a mission-driven organization, we strive to balance competitive pay with our mission. New hire salaries are typically between the range minimum and the salary range midpoint. Actual placement in the range will depend on a candidate's job-related skills, experience, and expertise, as evaluated during the interview process. #LI-CM1 Hiring Requirements As part of our standard hiring process for new employees, employment will be contingent upon successful completion of a background check. Candidate Accommodations We're committed to providing an inclusive and accessible hiring experience for all candidates. If you have a disability or medical condition and need an accommodation at any stage of the application or interview process-such as an ASL interpreter, alternative interview format, or physical accessibility support-we're happy to help. Please contact HR@gatesfoundation.org with the position number and a brief description of your accommodation needs. Requests will be handled confidentially. Inclusion Statement We are dedicated to the belief that all lives have equal value. We strive for a global and cultural workplace that supports ever greater diversity, equity, and inclusion - of voices, ideas, and approaches - and we support this diversity through all our employment practices. All applicants and employees who are drawn to serve our mission will enjoy equality of opportunity and fair treatment without regard to race, color, age, religion, pregnancy, sex, sexual orientation, disability, gender identity, gender expression, national origin, genetic information, veteran status, marital status, and prior protected activity.
