Prolific
You'll join Prolific's Supply team, which is responsible for the health and growth of our participant marketplace, the supply side of our two-sided marketplace connecting participants and researchers. This is a new role on an established Supply Data Science team, focused on marketplace dynamics—in particular understanding and predicting participant supply, demand, and quality, and using that to improve how participants are matched to studies. You will work closely with existing specialists in this space to find, validate, and model useful signals for participant supply and quality and turn promising directions into production systems. The ideal candidate will help define the right problems to solve, not just execute against a fixed brief.
The role
The Applied Scientist role is new to Prolific. It combines data science, ML, and statistics to build practical systems that drive real business outcomes. This isn't a pure research role, although you may explore papers and explore new ideas. The focus is on turning promising approaches into production-ready solutions. It is also not an ML engineering role: you don't need engineering experience, but you should understand what deploying a model involves and the practical constraints around it. We care about approaches that actually work in production, not ones that are too slow or expensive to run, and about the judgement to tell the difference.

Nice to have
How you'll work
You don't need to meet every point above to apply. If you have strong depth in the essentials and are interested in the work, we'd like to hear from you—we know good candidates, particularly from underrepresented groups, often hold back unless they match everything. We're happy to adjust any part of the interview process to work better for you — just let us know what would help.

Most staff roles are open to remote candidates across the UK and US, and the offices in London, Manchester, and New York are optional drop-in spaces rather than required locations. A small number of sales and customer success positions are advertised as hybrid out of London or San Francisco, so it is worth checking the specific role you are interested in.
No. Alongside its salaried staff jobs, Prolific runs a large network of paid AI trainer and study participant opportunities that appear on the same careers board but are contract and participant work rather than full-time employment. If you are looking for a staff role, focus on teams like Engineering, Data and AI, Product, or Human Data.
Prolific uses a location-based pay model, so salary bands are calibrated to the region a role is hired in rather than a single global rate. The bands are shared openly as part of the hiring process instead of being negotiated from scratch.
Prolific suits people who want to work remotely with a high degree of flexibility and who are drawn to the human data infrastructure behind AI research and academic studies. Because roles range from engineering and data science to product and participant operations, it fits both technical builders and operations-minded people.
