Technical Lead; Hands

Position: Technical Lead (Hands-On)
Location: City of Westminster

About the Opportunity

We’re hiring on behalf of a venture-backed fintech startup building an AI-driven platform that is reshaping how investors analyse and manage alternative assets such as private equity and private credit.

The company has already built its MVP and secured backing from experienced fintech founders and senior leaders in financial services. The next phase is about scaling the platform properly: building robust architecture, clean engineering practices, and production-grade systems.

They’re now looking for a hands-on Technical Lead who wants to stay close to the code while helping shape the technical foundation of the platform.

The Role

This role is for someone who wants to lead through engineering, not meetings.

You’ll still be writing code daily while helping define how the platform evolves technically.

Working closely with the CTO, you’ll help design and develop an AI-native SaaS platform that automates due diligence and investment workflows in a legacy financial industry.

Your impact will come from building great systems, setting high engineering standards, and solving complex technical challenges alongside the team.

What You’ll Be Doing

You’ll take ownership of the architecture of an AI-driven investment intelligence platform while remaining hands-on across the stack, from frontend interfaces through backend services, AI integrations and infrastructure.

Working closely with product leadership, data scientists and the CTO, you’ll contribute to both the technical direction and product evolution.

As the team grows, you’ll help guide and mentor a small engineering group, setting the technical bar through example while helping ensure the platform is scalable, secure and reliable.

You’ll also have the opportunity to experiment with emerging AI frameworks, tooling and infrastructure as the platform evolves.

* 2+ years operating at senior or lead level

Why Join

* Work on a technically ambitious AI platform within fintech

* Stay deeply hands-on while influencing core architecture

* Partner closely with an experienced CTO and strong founding team

* Real ownership, your technical decisions will shape the product
