About Us

We are building a modern ERP platform for the waste industry, expanding our team after a successful seed funding round.

Our mission is to help waste and recycling companies run more efficiently through smarter software, leveraging AI and data in everyday operations.

What You'll Do

  • You will join a small, experienced team working directly with customers to design, build, and improve the platform.
  • You will have ownership across the stack - UI to database - and contribute to product thinking, not just implementation.

Your Role

  • Ruby on Rails 8.
  • Hotwire (Turbo, Stimulus, Turbo Native).
  • PostgreSQL.
  • TailwindCSS.
  • ViewComponent.
  • Minitest.
  • GitHub + CI/CD pipelines.

Who We're Looking For

  • You don't need to tick every box, but you might be a great fit if you:
  • Experience with mobile apps (Turbo Native a plus).
  • Background in B2B or ERP products.
  • Interest in environmental or waste sectors.

This is an opportunity to be part of a purpose-driven company modernising a neglected industry, shape a product early in its lifecycle, and work closely with customers, not just specs.
Competitive salary and flexibility available.
