• 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.
