Senior Python Backend Developer

🚀 Senior Python Backend Developer 📍 London, 3 days per week in office 💰 £80,000-£90,000 + Bonus 🐍 Python | Django | Flask | Pandas | APIs | Data Pipelines A growing engineering team is looking for a Senior Python Backend Developer to join as the platform continues to scale following a number of new client wins. They’re looking for a strong software engineer first, someone who enjoys building backend applications and APIs, but is equally comfortable working with data-heavy systems, pipelines and calculation engines. The successful engineer will join a small team where there is plenty of opportunity to influence how things are built. Initially, they’ll get hands-on with the existing platform before taking increasing ownership of features and technical components. They’ll be working across: • Core Python backend services and APIs • Django and Flask applications • Pandas and data-processing workflows • Data pipelines and calculation engines • Performance, scalability and reliability • Architecture, testing, observability and continuous delivery The team is also looking to improve its approach to data orchestration, so experience with Airflow, ETL or similar tooling would be particularly useful. This isn’t a pure Data Engineering or Big Data role. The sweet spot is a strong generalist Python engineer who has built production software and is comfortable solving data-heavy backend problems. They’d ideally like someone who has worked within a startup or scale-up environment, enjoys ownership and is comfortable operating without layers of product or management around them. There is also scope over time to take on broader technical ownership, planning or people leadership. ❗ No visa sponsorship available. Interested, or know someone who could be a good fit?
