  • Implement file uploads (e.g., S3) within user flows.
  • Contribute to the messaging system for real-time interaction.
  • Participate in architecture discussions to ensure security, scalability, and maintainability.
  • Potentially integrate payment solutions in later phases.
  • Iterate quickly with the product team, refining features and delivering a robust MVP.

  • Comfortable designing/building REST/GraphQL or tRPC APIs.
  • Skilled with PostgreSQL/MySQL and ORM tools (Prisma or similar).
  • Experienced with NextAuth.js or Auth0 for authentication.
  • Familiar with S3 (or equivalent) for file uploads.
  • Up to date and productive with AI coding tools.
  • Strong Git /CI/CD skills (Vercel, GitHub Actions).
  • Effective communicator who aligns technical decisions with business goals.

Bonus

  • Real-time features (WebSockets, Socket.IO, or Pusher).
  • UI/UX with Tailwind CSS , MUI, or similar.
  • Payment integrations (Stripe, PayPal, etc.).
  • Marketplace or platform-building experience.

Why Join

  • High Impact : Shape a new platform from day one.
  • Ownership : Lead critical features end-to-end.
  • Flexibility : Remote-friendly, with a Milwaukee base if you prefer on-site.
  • Growth : Expand your role as the product evolves.

Compensation & Details
