Senior Software Engineer

Senior Backend Engineer (Python / Django) Remote (UK) with regular travel to London (1-week per month) Salary: £125-150K About the Business We're partnering with a venture-backed software company building an AI-first platform that helps users automate complex decision-making and operational workflows. Rather than acting as a traditional software tool, the platform continuously analyses context, coordinates intelligent systems behind the scenes, and proactively completes work on behalf of its users. The engineering team is still relatively small, meaning every hire has a genuine opportunity to influence architecture, product direction and engineering culture. Following strong early customer adoption and recent funding, the business is investing heavily in expanding its core engineering function. The Opportunity They're looking for a Senior Backend Engineer to join a highly collaborative engineering team building distributed backend systems that power AI-enabled products at scale.
