Founding Engineer - £100k plus equity

You are an engineer who gets bored when things move too slowly. This VC-backed startup is automating finance operations for modern companies, starting with accounts receivable—the messy, manual process of collecting revenue companies are already owed. The founders know what they are building, they know who needs it, and they need someone who can turn that clarity into code.

What You’ll Build

  • Own the revenue engine.
  • Build systems that parse usage-based contracts, automatically generate invoices from consumption data, and manage collections.
  • Design APIs integrating with billing platforms, create LLM-powered contract interpretation, and build data pipelines handling complex signals.
  • Shape the product from zero alongside the CTO.
  • Drive architecture decisions, technology choices, and product direction. Your early decisions define how this company scales.

You’re the Right Fit

  • 5+ years building and scaling systems at places that matter.
  • Full-stack with serious backend chops: TypeScript/JavaScript, Python, FastAPI, Next.js, PostgreSQL, ClickHouse.
  • Ready to ditch colleagues who think in terms of 'that’s not my job' - that doesn’t exist here.
  • You care about product and design decisions, not just technical ones.
  • 0-to-1 thinking excites you more than optimizing existing code.

What’s On Offer

  • ESOP Equity.
  • 25 paid holidays + public holidays.
  • Health and dental insurance.
  • £2k IT budget.
  • In-office role (London Bridge) with a great bunch of curious people.
