Founders Associate - Engagement Innovation (all genders)

RemoteBerlin, State of Berlin, Germany or Germany

Full TimeEntry LevelMedium

Job Summary

Partner with founders as a thinking partner on engagement mechanics, embedding across product teams to identify opportunities from single-line copy changes to entirely new features. Tear down top B2C apps like TikTok and Temu to translate their mechanics into JustPlay, then turn ideas into actionable outputs such as one-pagers, mocks, and test plans. Push concepts through to launch by making yourself useful to shipping teams, measure results honestly to scale or kill experiments, and build collective company instincts for engagement.

Required Qualifications

  • Exceptional consumer instincts: you can tell why something is fun or addictive, not just that it is
  • Extremely high agency: you find the problem, propose the answer, and chase it until it's live, without being assigned it
  • A genuine obsession with engagement mechanics in top B2C products such as games, social, commerce, or education
  • Evidence that your ideas have shipped and moved a number, however small the idea was
  • Fluency with data: you can read an experiment result honestly, including when it kills your favourite idea
  • You write and speak clearly enough to sell an idea to a founder and an engineer in the same afternoon
  • Comfortable being the newest voice in a room of people who know the product better than you and disagreeing anyway
  • You communicate fluently in English, both written and spoken

Desired Qualifications

  • Casual, hyper-casual, or rewarded mobile gaming experience
  • Background in LiveOps: events, seasons, progression, economies, or meta design
  • Hands-on experimentation experience: you've designed and read A/B tests
  • Enough technical or design literacy to mock something up yourself rather than describe it
  • Familiarity with loyalty and rewards mechanics, or the mobile advertising landscape
