Scored from the posting itself — how clearly the role is described, how much it says about pay and benefits, and how recently it was listed. Not a judgement of Prolific as an employer.

What you need

  • Deep expertise in mathematical optimization and recommendation algorithms applied to large-scale matching or marketplace problems
  • Judgement about when to reach for simple statistics, classical ML, LLMs, or agentic approaches
  • 5+ years applying ML, AI research, optimization, or recommendation systems to complex production problems
  • Python skills sufficient to build, test, and iterate on working prototypes independently
  • Ability to take a loosely defined product or customer problem and turn it into clear hypotheses, experiments, and metrics
  • Comfortable working on ambiguous problems and suggesting solutions rather than waiting to be told exactly what to do

Nice to have

  • An MSc or PhD in Computer Science, Maths, Statistics, Economics, Psychology, ML, or a related field—or equivalent knowledge gained another way
  • Experience working alongside product and engineering teams

What you get

  • Competitive salary
  • Benefits
  • Remote working
  • Impactful, mission-driven culture

Worth weighing

  • No specific salary listed
  • Role combines data science, ML, and statistics but is not purely research-focused
  • Candidates are encouraged to apply even if they don't meet every requirement
  • The role requires comfort with ambiguity and proactive problem-solving
