Lead Software Engineer - .NET / Azure / React - Remote First Are you the kind of Lead Software Engineer who enjoys taking a fairly messy collection of systems, data feeds, portals, and legacy platforms and gradually turning it into something modern, scalable, and genuinely slick? Maybe even enjoy the challenge of untangling it all a bit? Right now, the business has multiple products and platforms sitting across different environments. Some modern. Some older. Some nobody really wants to touch. The long-term goal is to bring everything together into a much more unified Azure-based platform with cleaner architecture, better product delivery, and a far more connected customer experience. This position will sit directly under the Head of Technology and will effectively become the senior hands-on engineering lead across the core platform estate. Primarily remote, the office is based in London, and you ll need to be able to get there on occasion for quarterly meetings and the odd product / development session. You must be UK based for this position. What we are looking for: Strong Senior / Lead .NET Developer background Deep experience with .NET, Azure, SQL, and modern backend architecture Some frontend experience with React or Angular (this is heavily backend leaning, not a 50/50 split) Strong experience building business-critical platforms, customer portals, subscription systems, or data-heavy products Comfortable working closely with Product, Data, and third-party enginee
