Prolific

Research Scientist

• Designing and executing polling and public opinion programmes: methodology development, questionnaire design, sampling strategy, weighting approaches, and data collection oversight
• Innovating on polling methodology: tackling hard problems, testing new sampling and data approaches, exploring synthetic data augmentation, and validating methods against real-world outcomes.
• Analysing and reporting: producing clear, compelling reports for internal teams, external partners, and media audiences
• Acting as a public face for Prolific's research: serving as one of our media liaisons for polling releases, providing expert commentary, and representing Prolific at industry events
• Building our polling infrastructure: collaborating with Marketing and Design teams to create data visualisations and develop a centralised polling hub
• Managing external relationships: working with PR partners, our marketing team, and cultivating media contacts to maximise the reach and impact of our work
• Contributing to wider research projects: applying your research expertise to other initiatives within the sciences team. Our current agenda includes evaluation of synthetic data approaches, data quality and representativeness research, and external research collaborations. We're looking for someone who wants to shape this agenda, not just execute on polling.
