• Scoping vague but important questions around AI x Animals — choosing the right depth, angle, and methodology for each, from literature reviews to modelling, data analysis, or expert interviews. • Conducting independent research on complex questions, addressing uncertainty and competing perspectives explicitly. • Engaging external stakeholders to understand their needs and shape deliverables to their specifications. • Producing decision-useful outputs from inception to delivery, in the best-fit format (report, model, dashboard), translated into practical recommendations for decision-makers. • Managing projects end to end — keeping them on track, reporting progress, and proactively identifying mitigations when barriers arise. The balance of these responsibilities, and the autonomy you'll have, depends on the level you're hired at. At the Senior Researcher level, you will own these responsibilities at higher autonomy and help co-create the overall research strategy for the program. You will also build and steward more external relationships with funders, advocates, and field experts.
