Job description

Lead Full Stack Engineer | Incubator for AI (i.AI)

Want to build AI products that improve public services used by millions?

At i.AI, we build AI products inside the UK Government across health, education, planing and Parliament. Small teams. Startup pace. National-scale impact.

We're looking for a Lead Full Stack Engineer who can own technical direction, shape product strategy alongside product managers, mentor and grow engineers, and stay close enough to the code to tackle the toughest challenges themselves.

You’ll work in a high-autonomy environment where teams move quickly, make decisions close to the problem, and focus on delivering real outcomes for users. Our engineers work across the full stack, from user-facing products and APIs to infrastructure, data layers and AI integrations.

Our stack:

Python (Django/FastAPI), TypeScript, React, Astro, Svelte, PostgreSQL, AWS, Terraform, and frontier AI models via Amazon Bedrock.

What you’ll get:

• High-autonomy, high-trust environment
• Access to frontier AI models and significant compute
• Backing from No.10 and the Prime Minister
• Small, empowered, cross-functional teams
• £77,425 - £105,460 + 28.97% pension contribution. Salary is dependent on location and skills assessed at interview.
• Hybrid working in London, Manchester or Bristol

If you're excited by the opportunity to solve meaningful problems with AI, we'd love to hear from you.

Appointment is conditional on successfully completing UK Government SC clearance. Prior clearance is not required - we will sponsor and support you.
