We're looking for Lead and Principal engineers to help shape the future of our brand-new platform - one with zero tech debt, a strong engineering culture, and serious backing (pre-seed valuation: £25m). This is a chance to have real ownership across product strategy, technical direction, and user experience, working closely with a tight-knit team of engineers who ship fast, think deeply, and care about craft. We’re building a B2B SaaS Martech product that helps marketing teams drive growth with less guesswork. If you’ve worked on enterprise-grade products and love startup energy, you’ll fit right in.

What We’re Looking For

  • Strong experience with React and TypeScript (Next.js a bonus)
  • Solid engineering fundamentals and a product mindset
  • Happy to work across the stack - ideally with Go (but if you’re fullstack in JS/Node/Express, with React on the front, we’ll teach you Go)
  • Comfortable working in teams that own everything from design to deployment
  • Lead Experience

Our Stack: Go, TypeScript, React, Next.js, Node.js, AWS, Vercel, Kafka, Redis, Postgres

  • Latest MacBook and your own company card to get what you need
  • 25 days holiday + full Bupa health cover
