Junior Python Developer

Remote | Permanent

£25,000 - £35,000

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.
