Translate core research needs into tailored technical solutions using rigorous mathematical and computational methods, refining solutions iteratively through tight feedback loops to ensure maximum impact and practical utility. Communication & Partnership: Build and maintain trust-based relationships across IDM, the Foundation, and research partners. Communicate complex technical concepts clearly to both technical and scientific audiences by adapting to distinct partner contexts, securing alignment on strategic technical approaches, and empowering research collaborators to spend less time on execution hurdles and more time advancing science. Modeling Technologies: Turn proven solutions into repeatable, reusable capabilities that provide a trusted foundation for IDM research. Determine how best to design these capabilities to maximize their impact to researchers’ work, with a focus on elegant, easy-to-understand solutions that adapt readily across research contexts. Work across IDM’s computational modeling paradigms, including agent-based, compartmental, and statistical approaches. Technology Frontiers: Introduce new technological approaches that increase the rigor and speed of science and model-informed decision-making, with an emphasis on AI. Rapidly prototype and evaluate emerging methods, integrating the most promising into IDM’s work. Help shape how IDM applies AI responsibly and effectively. Technical Execution: Produce well-designed, well-tested, maintainable code with strong use of modern engineering practice. Effectively use AI development tools to accelerate code development and improve quality. Explore, validate, and communicate emerging engineering practice back to the team. Autonomy & Delivery: Independently plan and execute work across concurrent projects, coordinating with teammates to keep deliverables on track with minimal supervision. Communicate proactively when timelines or priorities shift and escalate risks clearly with proposed solutions. Team Culture & Growth: Exemplify team culture, DEI norms, and collaborative engineering practice for partners with a broad range of technical capability. Serve as a reliable go-to within the team for technical direction, design reviews, and problem escalation. Your Experience Typically, 5–8 years of professional software engineering experience in scientific programming (e.g., Python, R), ideally involving research software, computational modeling, and cloud-based solutions for data access and processing, or equivalent impact. Hands-on experience building with generative AI, including agent design, tool use, and context management, in production or research-grade environments, along with a working grasp of how AI system quality gets measured and improved. Knowledge of and hands-on experience with computational modeling, such as agent-based modeling (ABM), compartmental models, or statistical/ML approaches. Experience collaborating closely with researchers, applied scientists, or domain experts in global health or public health settings. Demonstrated ability to deliver well-tested, maintainable code leveraging modern engineering best practice. Ability to work independently on multi-week tasks, communicate tradeoffs clearly to both technical and research audiences, and adapt priorities based on manager and team feedback. Preferred Experience Familiarity with open-source software development practices, including contributions to project, workflows, documentation standards, and community engagement. Exposure to cloud-based data and compute platforms used for large-scale analysis or simulation workloads. Hands-on experience with production AI system design, such as orchestration across long-running tasks, evaluation harnesses, and guardrails, at a level that could help guide practice for a team. Background in epidemiology, computational biology, infectious disease modeling, or scientific computing. Proven ability to design adaptable, low-barrier software and data solutions tailored to be used in resource-constrained environments.
