We're working with one of the fastest-growing B2B SaaS companies in Europe, recognised by both the Financial Times and Sunday Times as a standout place to work in 2025. They're building genuinely useful AI and automation products for people-intensive industries, and the engineering team is one of the most thoughtful I've come across at this stage. High standards, no ego, and real ownership culture.

The role in a nutshell: You'll be working across the stack, Python backend primarily with some frontend (Svelte/jQuery), building features end to end and genuinely owning your work from design through to deployment. This isn't a ticket factory environment. They want engineers who think about why something is being built, not just how.

You'll likely be a fit if you:

  • Have solid Python backend experience in a startup or scale up
  • Care about code quality and long term maintainability (not just shipping)
  • Work well across product, QA, and engineering without needing hand holding
  • Have any exposure to LLMs, AWS, or third party API integrations (a bonus, not a must)

What's on offer: ~ Up to £90k, private health/dental/vision (Aviva), remote or hybrid working, 25 days leave, regular hackathons, and a team that actually invests in your growth.
