• Work closely with UX Designers to translate user journeys, wireframes and prototypes into production-ready interfaces.
• Integrate frontend applications with REST APIs, workflow services and identity/access mechanisms.
• Develop role-aware dashboards, task views, status tracking and operational work queues.
• Apply accessibility, responsive design and usability best practices.
• Participate in agile ceremonies, sprint delivery, demonstrations and user feedback sessions.
• Contribute to frontend testing, quality assurance and continuous improvement.

• Demonstrable experience delivering software within MOD, Defence, National Security or similarly secure environments.
• Strong commercial React development experience.
• Strong Type Script capability.
• Experience consuming REST APIs and collaborating closely with backend engineering teams.
• Experience building responsive, accessible and maintainable user interfaces.

• Experience with Material UI, (url removed) Design System, MOD design patterns or equivalent component frameworks.
• Experience developing workflow-driven applications.
• Experience implementing secure authentication and role-based access control.
• Experience developing search-led user interfaces.
• Experience supporting applications deployed in classified or highly regulated environments.

• Current DV Security Clearance.
• Ability to work onsite at an MOD location in London four days per week.
• Previous experience delivering within MOD, Defence, Defence Intelligence, Strategic Command or wider National Security organisations.
• Comfortable working with OFFICIAL-SENSITIVE and classified material where authorised.

• Agile delivery within a multidisciplinary team.
• Close collaboration with Defence stakeholders, Product, Delivery, UX and Engineering teams.
• Secure-by-design approach with a strong focus on audit, traceability, access control and assurance.
• Practical focus on creating intuitive, reliable applications while maintaining operational accountability.

We're interested in Front End Developers who can demonstrate:
