Lead Software Engineer

We're looking for a Lead AI Software Engineer to be the most senior technical voice in one of our product squads, working as a technical co-leader alongside the Engineering Manager. You'll own the squad's technical direction and engineering quality end to end, from architectural decision making and hands-on delivery, to mentoring engineers and shaping how we build across the organisation. This role demands genuine depth in AI. You'll be leading LLM powered feature development and setting the standard for how AI tooling amplifies the whole engineering process, combined with the full-stack and cloud-native chops to back it up.

Setting technical direction for your squad. Owning architectural decisions, managing technical risk, and representing the engineering perspective at our Architecture Review Board

Driving adoption of AI coding tools across the full SDLC, from planning and design through code review, testing, deployment and setting the bar for how the squad works

Delivering production grade code across the full stack: Node.js or Python backends, event-driven AWS architecture, and React where the squad needs it

Mentoring and growing engineers across AI and full-stack domains, through code reviews, design documents, and day-to-day pairing

Collaborating with platform teams to consume shared capabilities and contribute reusable patterns back, not building one-off solutions when a platform component will do

Ensuring everything we ship is compliant-by-design, auditable, and built to the standards expected of software in FCA regulated financial services

A seasoned engineer with 10+ years of experience, including meaningful time building and operating AI/ML systems in production

Real technical leadership. You've set direction, made architectural calls, mentored others, and influenced how a team builds, not just what it ships
