What You’ll Bring:

Strong experience building production-grade React applications with TypeScript, hooks, and modern state management Proven capability delivering rich data visualisations using D3, Recharts, Plotly, or similar libraries Experience creating interfaces that surface AI outputs; from LLMs, knowledge graphs, or analytics pipelines Familiarity with design systems, accessibility, and responsive UI practices Comfortable integrating front ends with data-heavy APIs or real-time backends (Bonus) Prior experience in Defence, government, or enterprise-class security environments

Why This Project?

You’ll be building the front end of real AI-powered tools for Defence decision-makers where clarity, usability, and reliability matter. From edge deployments to secure systems, this is work that will be seen, used, and relied on.
