Contract | Inside IR35 | £600–£700/day | Hybrid / Secure Site | SC/DV Cleared | UK Nationals Only
Contract Length: Initial 3-month engagement (rolling), part of a 6–9 month roadmap
We’re supporting a cutting-edge AI organisation delivering a government-funded mission into the Defence sector. They’re seeking a talented Front-End Engineer to help build and iterate on user interfaces that bring complex machine learning outputs to life - transcription analysis, graph-based risk models, and natural-language interfaces for end users in secure, disconnected environments.
This is not your typical dashboard gig. It’s a chance to design and build offline-first, insight-rich tools that support real-world decision-making—where clarity and usability can have operational consequences.
What You’ll Be Doing:
Designing and developing React-based UIs for: Live and retrospective transcription review Graph navigation and data visualisation Natural language querying Insight generation and reporting Building robust, offline-first interfaces that run in air-gapped, secure environments Creating visualisation components (e.g., networks, timelines) to support scenario analysis Integrating with backend APIs delivering LLM, NLP, and structured data outputs Contributing to internal design systems and building reusable, scalable components Collaborating closely with users and the wider delivery team to evolve features through feedback
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.
