Role - Python Focused Senior Software Engineer

Location - London

Salary - £90k - £110k


0→1 Senior Software Engineer (Small Team real impact)

Stack - Python, Go, AWS


Joining a small team who are building a 0→1 product, so this is properly early, shaping the architecture, product direction and core technical decisions from day one.


What makes it a bit different:

  • You’re not joining a big existing team — this is closer to a founding engineer environment, but with the backing, data access and distribution of a large, established business
  • The product is data-first (not feature-first), multiple data sources, messy real-world financial data and a focus on building something genuinely useful for decision-making rather than dashboards for the sake of it
  • They’re intentionally keeping things greenfield and modern (AI-assisted workflows, no legacy constraints)


We are looking for someone comfortable operating in ambiguity, making early architectural calls and helping shape something from first principles.
