PowerFunds is building the decision layer for everyday investors – think Skyscanner + watchdog for investing.


We’ve launched in the UK and Sweden, grown to 6,000+ users in just a few months, and are now entering an intense 120-day growth sprint. This is about proving scalable unit economics ahead of a larger funding round this summer.


We’re looking for a Junior Data Scientist (Intern) to help build the intelligence layer that drives this next phase.


This is not a passive internship. You will work directly with the founders and growth team on real metrics, real experiments, and real decisions.

Bonus:

  • Experience with analytics tools (GA, Mixpanel, Amplitude etc.)

What you get
  • Work directly with experienced founders and operators
  • Be part of a high-intensity startup sprint with clear goals
