About the role

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. Our vision: become the Hubspot for creator marketing, powering brands and creators across TikTok Shop, YouTube Shopping, Instagram, and Amazon. We're building AI-powered infrastructure that will be core to the rapidly growing creator economy.

What you'll build:

  • Full-stack features that ship to production within days
  • AI agents, LLM-powered tools and ML pipelines processing millions of creator/brand interactions
  • Backend systems (Python, FastAPI, PostgreSQL, GCP)
  • Responsive UIs (React, Tailwind, shadcn/ui)
  • Direct customer features - no throwaway intern projects

Our culture:

  • Collaborative by default - we pair on hard problems and celebrate wins together
  • 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)
  • Resourceful and comfortable with ambiguity

Bonus:

  • Previous startup/tech internship
  • ML/AI coursework or projects
  • Deployed apps with real users
  • Side projects or open-source contributions
  • Interest in AI/e-commerce/creator economy

Location: San Francisco (in-person)

Technology

Python and React platform using LLMs & CV models powering automated creator discovery, chatbots, video search, payment flows, and an AI agent framework that handles marketplace tasks end-to-end.
