This is a hands-on full stack development opportunity within a company that creates enterprise software for demanding, highly controlled environments such as defence and aerospace. The product is a training and resource management platform that supports complex operational lifecycles, so the work is focused on core business functionality rather than surface-level web content. Reliability, compliance, auditability, and traceability are central to the role.<\/p>\n

The business has recently secured several new contracts and is now moving through a period of strong growth. Because of that expansion, they are looking for developers who can make an immediate contribution and help deliver robust, high-quality software at pace.<\/p>\n

What you will do<\/h3>\n
    \n
  • Build new product features and improve existing functionality in an enterprise application used in regulated, high-stakes settings.<\/li>\n
  • Work on software where quality, traceability, and dependable behaviour are essential.<\/li>\n
  • Contribute as a practical, delivery-focused engineer in a remote-first team.<\/li>\n
  • If you are hired at mid-level, your main focus will be feature development and enhancement work.<\/li>\n
  • If you are hired at senior level, you will take ownership of important areas of the product and drive work from early design through to release.<\/li>\n
  • Develop within a complex application environment, including systems that are commonly deployed in private cloud infrastructure.<\/li>\n
  • Write code that follows structured, maintainable design approaches.<\/li>\n
  • Take part in pull request-based code reviews.<\/li>\n
  • Use unit testing as part of everyday development, with test-driven development preferred where it makes sense pragmatically.<\/li>\n
  • Work independently while still collaborating effectively with the wider engineering team.<\/li>\n
  • For senior-level work, get up to speed quickly in an established codebase and operate with a high degree of autonomy.<\/li>\n<\/ul>\n

    Technology and engineering approach<\/h3>\n
      \n
    • Backend development is based on .NET and C#.<\/li>\n
    • The frontend uses Vue.js, although experience with React is considered transferable.<\/li>\n
    • JavaScript is part of the frontend stack.<\/li>\n
    • Unit testing is expected.<\/li>\n
    • Test-driven development is preferred, but the team takes a pragmatic approach rather than insisting on dogma.<\/li>\n
    • Code quality is supported through pull request reviews.<\/li>\n
    • The team values structured, maintainable design patterns and clean application architecture.<\/li>\n<\/ul>\n

      What they are looking for<\/h3>\n
        \n
      • Experience building application-level software, not just websites, CMS platforms, or marketing pages.<\/li>\n
      • A solid grasp of business logic and how to design software in a structured way.<\/li>\n
      • Comfort with unit testing and attention to test coverage.<\/li>\n
      • Knowledge of design patterns and clean architecture principles.<\/li>\n
      • A pragmatic mindset with a strong focus on delivery.<\/li>\n
      • Confidence working independently in a remote-first environment.<\/li>\n
      • For senior applicants, the ability to own features or modules end to end.<\/li>\n
      • For senior applicants, the ability to become productive quickly inside an existing codebase.<\/li>\n
      • For senior applicants, strong autonomy; this is not a formal leadership role, although progression is possible.<\/li>\n<\/ul>\n

        Helpful background<\/h3>\n
          \n
        • Experience in regulated industries such as defence, aerospace, healthcare, or fintech would be advantageous.<\/li>\n
        • Experience with secure environments or private cloud deployments would be useful.<\/li>\n
        • Exposure to AI tools in development workflows would be a bonus.<\/li>\n<\/ul>\n

          Working arrangement<\/h3>\n
            \n
          • The role is remote-first.<\/li>\n
          • There is an initial onboarding period on site in Oxfordshire.<\/li>\n
          • The team meets in person quarterly.<\/li>\n
          • Office access is available if needed, but it is optional.<\/li>\n<\/ul>\n

            Package and progression<\/h3>\n
              \n
            • The salary range is \u00c2\u00a340,000 to \u00c2\u00a365,000.<\/li>\n
            • Exceptional candidates may be considered above that range.<\/li>\n
            • The company is scaling after recent contract wins, so there is strong growth momentum.<\/li>\n
            • Although immediate leadership duties are not part of the role, there is a clear path for progression over the next 6 to 12 months as the team grows.<\/li>\n<\/ul>\n
