Senior/Principal Python Engineer Front Office Technology £800-£850 inside IR35 (could flex for the right candidate) London - Hybrid We’re looking for a senior Python engineer to join the front office technology team of a major financial player on a long-term contract. The role sits within a core engineering group that supports multiple investment teams with an increasing focus on Python as the go-to language across the platform. You’ll be building tooling and infrastructure that directly supports front office users - including data pipelines, execution workflows, and analytics capabilities. The team operates in a modern engineering environment with a strong DevOps culture and close collaboration with investment professionals. They are investing heavily in AI so you will get exposure to interesting projects in this space and also be able to leverage tools to help improve your experience and productivity as an engineer. What we’re looking for: Strong Python engineering background – ideally within front office environments. Experience building data-centric platforms or tooling used by PMs, researchers, or risk teams Familiarity with modern CI/CD, cloud-based infrastructure, and containerised deployments Ability to work closely with users and own solutions end-to-end The contract is inside IR35 with hybrid working in central London. Initial term is 6 months but highly likely to extend – this is a business-critical buildout that’s still gaining investment. If that sounds like something you’d be a good fit for, get in touch and I’ll walk you through the details.
