A software company in London is looking for a Tech Lead (Python) to join and guide their engineering team. They operate in a fast-paced environment where engineers prioritise quick delivery, practical problem-solving, and real-world impact over perfect code. It’s an outcome-driven culture with plenty of autonomy, where developers take ownership across the full lifecycle of their work. As a Tech Lead, you’ll combine hands‑on development with technical leadership, helping shape architecture, mentor engineers, and drive engineering standards across the team. What You’ll Work On

Building integrations with new data and liquidity sources using advanced web‑scraping and reverse‑engineering techniques. Developing and maintaining low‑latency, real‑time data feeds to support internal strategies. Improving system visibility and observability to help identify integration issues and areas for optimisation. Leading an agile team with a flexible, evolving roadmap driven by new information and opportunities. Taking ownership of software delivery from design through to development, testing, review, deployment, and production support.
