Global Leading Tech Trading Firm

Our client, a global leading tech trading firm, is hiring a Python Developer to join its technology team in London. The firm operates at serious scale in fast-moving financial markets, and engineering sits right at the centre of how the business runs.

You’ll work across a mix of production systems and internal tooling, with the scope to move between projects as priorities shift. It’s a good fit for someone who likes variety, takes ownership without needing much oversight, and writes clean, maintainable code under real production pressure.

Key responsibilities

• Develop and maintain backend services and internal applications supporting business-critical operations.
• Build tooling to improve how internal teams monitor, manage, and act on operational data.
• Work on data-handling pipelines feeding downstream analytics and reporting.
• Collaborate with engineers and non-technical stakeholders to translate requirements into working systems.
• Take projects from initial design through to live production support.

Requirements

• Strong commercial Python experience (2+ years).
• Solid SQL and relational database skills.
• Experience in a regulated, fast-paced, or otherwise high-stakes production environment is a plus.
• Strong communication skills, with the ability to work across teams and translate technical detail for varied audiences.

What’s on offer

• A chance to join a technically serious, high-performing business where engineers are trusted with real responsibility early on. Strong compensation, sharp colleagues, and the opportunity to work on systems that genuinely matter to how the firm operates.
