Software Engineer - Data Science Based in Bristol Salary up to 65k + Overtime, Bonus, Pension Most software engineers spend their careers shipping incremental updates to things that already exist. This isn't that. This role sits inside a concept programme, which means you're not maintaining a product roadmap, you're helping shape what comes next. You'll be working with complex datasets, building scalable systems with embedded data science capabilities, and translating experimental ideas into production-ready solutions. If that sounds vague, it's intentional. The work is classified. What we can tell you is that it matters, the technical challenges are real, and the people you'll work alongside are genuinely good at what they do. What you'll bring: Strong software engineering fundamentals (C++, Java or similar), a solid grounding in data science or machine learning, and the kind of mindset that's comfortable in ambiguity. You don't need to have all the answers. You do need to be curious enough to find them. Security clearance is required, so British citizenship is essential. If the thought of working on something you can't talk about at dinner sounds more appealing than frustrating, we should speak.
