About this position
Leiden University is advertising a Scientific Programmer / Post-Doctoral Researcher position on Project Hippocampus: The Future of OpenML, based in Leiden, the Netherlands, within the Leiden Institute of Advanced Computer Science (LIACS) and the ADA (Automated Design of Algorithms) group.
The role is centered on OpenML, an open science platform for sharing datasets, models, benchmarks, workflows, and evaluations through open standards and structured APIs. The project aims to redesign the platform and build the next generation of OpenML with better accessibility, more user-centered interfaces, agentic interfaces, and stronger integration with external data and compute infrastructure such as HuggingFace and DataVerse. The work also includes improving maintainability of the codebase and contributing to community code reviews.
The successful candidate will join a collaborative team spanning several universities and will work closely with project members across the Netherlands. The position offers visibility in the international research community, opportunities to present at conferences, and a pathway toward open-source leadership through participation in the OpenML core team.
LIACS is part of Leiden University and is located in the Bio Science Park, a major science hub where academia and industry meet. The institute emphasizes excellence, diversity, and a supportive environment, and it hosts strong programs in computer science, data science, and related areas.
The post is funded as an employment contract initially for one year, with the possibility of a two-year extension after positive evaluation. The salary is between €3,546 and €5,538 gross per month for a full-time 38-hour appointment, with holiday allowance, end-of-year bonus, pension contributions, commuting reimbursement, home-working support, and a laptop. Conference travel funding is also provided.
Eligibility highlights include experience in larger engineering teams, work with complex web-based codebases, and demonstrable experience with machine learning software/platforms such as OpenML, scikit-learn, or scipy. The vacancy requests a motivation letter, CV, GitHub portfolio, and names and contact details of at least two academic or programming references. The preferred start date is September 1, 2026, and the application deadline is October 15, 2026.
