Role – Python Focused Senior Software Engineer
Location – London
0 to 1 Senior Software Engineer (Small Team real impact)
Stack – Python, Go, AWS
Joining a small team who are building a 0 to 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.
