Job Description:

Lead AI Engineer | Up to £150,000 + Benefits | London (Hybrid, 2 Days)

What is this role, and what will you be building?

You’ll be working for a tech-first SaaS company building one of the most advanced AI platforms in FinTech right now. The product is already used by all of the world’s top 10 biggest banks, and more!

You’ll be working on an AI platform that, every day, analyses hundreds and hundreds of thousands of financial documents with 99.99%+ data extraction accuracy, turning hours of manual analysis into seconds.

This role isn’t about building demos or proof of concepts.

It’s about building production AI that customers rely on.

You’ll stay hands‑on, building AI systems while mentoring engineers, influencing technical direction and shaping architecture, without the line management. Engineering Managers handle the people side so you can focus on solving problems and writing great software.

The biggest reason engineers join isn’t the salary.

It’s because engineers don’t stagnate here. Almost everyone I’ve spoken to has said it’s the role where they’ve learnt the most and become the best engineer they’ve been.

The engineering team is exceptional, the product is complex and you’ll be surrounded by people who’ll push you to become a better engineer.

The engineering culture deserves a mention too. It’s one of the best I’ve seen. People are trusted to get their work done, not micromanaged. There’s flexibility and they understand life doesn’t stop outside of work.

If you’re looking for a role that keeps you close to the code while giving you the opportunity to shape both the product and the engineers around you, I’d love to tell you more.

Apply with your CV or LinkedIn profile. We can sort everything else afterwards.
