Principal Applied AI Engineer

Principal Applied AI Engineer | Incubator for AI (i.AI)

At i.AI, we're building AI products inside the UK Government that are transforming public services across health, education, planning and beyond.

We're looking for a Principal Applied AI Engineer to set the technical strategy for Applied AI delivery and lead a portfolio of products that reach national scale.

What will I be doing?

• Setting the overall strategy for Applied AI delivery and defining goals across product work streams
• Leading execution of a portfolio of products, navigating ambiguity to ship pioneering AI solutions that transform departments, sectors or policy areas
• Identifying key talent gaps — technical and product — and pitching in the talent needed to close them
• Mentoring and coaching the next generation of AI engineering principals
• Owning a major platform or tool, and advising the wider government on long-term technical strategy

Our stack: Python, TypeScript, AWS, Azure, GCP, PyTorch, LangGraph, LangChain, DSPy, Langfuse, Inspect and access to the latest frontier models.

What we're looking for:

• Significant experience leading the technical direction of large-scale, frontier AI products or delivery of frontier AI solutions, or founding innovative tech ventures — recognised as an AI leader, potentially internationally
• Proven ability to navigate ambiguity and ship products that transform departments, sectors or policy areas
• Strong networks across the tech sector; deep experience in a core public sector domain (health, planning, education, etc.) preferred
• Deep subject-matter expertise in one of the three core disciplines — Entrepreneurship, ML/DL or Full Stack Engineering — and strong working capability across the remaining two
• A track record of world-class technical leadership, with the credibility and standing to attract and inspire high-calibre talent to the organisation

What's in it for me:

• Salary of up to £145,000 (Base £71,525 + Technical Allowance £73,475), plus a 28.97% employer pension contribution
• London, Manchester or Bristol (Hybrid, with flexibility for occasional remote work abroad); Fixed-term (24 months — happy to discuss)
• 25 days annual leave (+1 per year of service), up to 39 weeks paid parental leave, home-office equipment stipend, plus discounts on cycling, dental insurance, retail and gyms

We know great talent comes from a range of backgrounds and experiences. If you're a pioneering technical leader excited about shaping the future of public sector AI, we'd love to hear from you.
