Front-End Engineer (Contract) – Secure AI Systems for Defence

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
