Junior Python Developer

Junior Python Developer Remote | Permanent Nigel Frank International is working with a growing trading technology business to recruit a Junior Python Developer. This is an excellent opportunity for an early-career developer to work on the software that powers live trading strategies. You will join a small technical team, work closely with experienced engineers, traders and researchers, and gradually take ownership of components as your confidence and experience grow. You do not need previous trading-industry experience. What matters most is strong Python capability, a genuine interest in building reliable systems and the ability to work independently while communicating clearly with others. What you will be doing

• Develop strategy components and shared Python libraries from designs and specifications created by traders and researchers.
• Extend integrations with trading venues and brokers, including new endpoints, order types and improved error handling across REST and WebSocket APIs.
• Investigate issues in live systems, including dropped connections, unexpected API responses and data-quality problems.
• Build and improve dashboards, logging and visibility into how trading strategies and systems are performing.
• Write tests, review code and improve the areas of the codebase you work on.
• Work alongside senior engineers initially, before taking greater ownership of systems and components. What we are looking for
• 1–3 years' commercial experience as a Software Engineer, Python Developer, Backend Developer or similar.
• Strong Python skills beyond simple scripting, with experience contributing to a larger codebase or production application.
• Working SQL and general database knowledge.
• Experience calling HTTP APIs and working with streaming data through WebSockets.
• Comfortable using Git and collaborating with other developers.
• Able to debug unfamiliar or complex codebases methodically.
• Clear communication skills, with the ability to explain problems and solutions to both technical and non-technical stakeholders.
• Self-motivated, curious and comfortable working independently. Desirable skills
• Asynchronous Python.
• Dashboards, visualisation, monitoring or centralised logging.
• Docker, CI pipelines or cloud platforms — particularly Azure.
• Open-source contributions or personal technical projects.
• An interest in financial markets, trading or quantitative finance. If you are a strong Python developer looking for an opportunity to build real-world systems in a technically interesting, fast-moving environment, apply today or contact Nigel Frank International for a confidential discussion.
