We're the #1 TikTok Shop partner helping brands like Under Armour, Hanes, and Logitech scale their affiliate marketing. We've crossed 7 figures in ARR and are raising our seed round.

  • No egos, no politics - just a tight team building something cool
  • Direct customer access - you'll talk to brands and creators regularly
  • High trust, high output - we give you real responsibility from day one
  • We actually like hanging out together (team dinners, office games, etc)

Requirements:

  • CS major with core coursework completed
  • Full-stack project experience (personal, hackathon, or coursework)
  • Available for 10-12 weeks (Sept/Oct - Dec 2025) or (May/June - August 2026)
