Contract Role - Principle/Lead Full Stack Developer

Principle/Lead Full Stack Engineer – Contract Role

I’m working with a global technology consultancy supporting a leading London-based insurance organisation that’s investing heavily in AI and looking for a Principle/Lead Full Stack Engineer on a contract basis to help build the next generation of intelligent internal products.

They’re looking for generalist builders – engineers who enjoy solving problems across the stack, take ownership of products, and use modern AI technologies to deliver real business value.

Details:

• Initial 6-month contract
• Hybrid  – 2 days a week onsite in Central London
• Day rate: £500 – £600
• Outside IR35

You’ll have experience with:

• Python, TypeScript, Go, Rust or another modern programming language
• React or another modern frontend framework
• API design, distributed systems and system architecture
• Building and shipping production software
• Working across backend, frontend, infrastructure and debugging

AI is a key part of the roadmap, with a focus on agentic orchestrationusing technologies such as LangGraph, LangChain and modern LLM tooling.Previous experience is desirable, but they’re equally interested in engineers who can quickly adopt emerging AI frameworks and apply them to real-world products. Experience deploying AI/LLM solutions into production would be a real advantage.

They’re looking for engineers who take ownership, thrive in fast-moving environments, enjoy shaping technical direction, and are comfortable making technical trade-offs rather than simply delivering tickets.

Previous insurance experience is beneficial but by no means essential – engineering capability and mindset come first.

If you’re excited by building modern software and want to play a key role in an AI-first engineering journey, I’d love to hear from you.
