Company Description

Materials Market is a managed marketplace for bulky construction materials. We’re fixing a fragmented, opaque market where pricing is political and access is unequal — building a fair, transparent system where customers and suppliers trade on equal terms. We turn a network of merchants and distributors into one simple way to buy heavy, first-fix materials. Customers — from DIYers to tradespeople — get competitive, market-informed prices and reliable delivery through a single platform. Suppliers keep control, choosing the orders that suit their branches, fleets and margins. We’re backed by Fuel Ventures and Active Partners, alongside a strong group of angel investors. Our board includes James Mackenzie (former Managing Director of Travis Perkins) and Thomas Studd (former Partner at Vitruvian Partners).

Role Description

We’re hiring a Ruby on Rails Developer to join a small, high-performing team and ship product changes end-to-end. You’ll work in a Rails codebase, building features across backend and frontend as needed, partnering closely with non-technical teams, and owning delivery, quality, and outcomes. We run lean, with minimal ceremony and a meeting-light culture (no daily stand-ups). You’ll have autonomy, direct access to leadership, and real ownership of what ships.

What you’ll do

  • Build and ship features in a Ruby on Rails monolith.
  • Contribute towards both new feature development and green-field rebuilds of core parts of our platform.
  • Deliver work end-to-end: from business problem → solution design → development → release.
  • Debug issues, improve reliability, and raise code quality.
  • Work pragmatically across the stack (Ruby, JavaScript, CSS, SQL).
  • Use AI-assisted / agentic development tools to write and review code, while maintaining high quality.

Must haves

  • Strong Ruby and Ruby on Rails experience with evidence of shipping production work.
  • Full-stack mindset; backend leaning.
  • Comfortable working with ambiguity and making pragmatic decisions.
  • Practical experience with AI-assisted development tools.

Nice to haves

  • Architecture experience.
  • CI/CD experience.
  • Infrastructure / DevOps exposure.
