AI is enabling small, elite teams to deliver outsized impact. My client is building a lean, talent-dense founding team in London to redefine how financial institutions operate. This is an opportunity to join at an early stage, shape the product from first principles, and help scale a platform that is already live, with paying customers and strong early revenue traction.
The product
My client is building an Agentic AI platform for financial institutions. Their AI agents remove real productivity bottlenecks across:
- Commercial banking
- Private credit
- Brokers and advisers
Agents are configured to each organisation’s workflows and integrate seamlessly with existing systems — no customer data training required. Human-in-the-loop is optional, automation is powerful, and productivity gains are tangible.
The vision
Every professional in this industry doing their best work, faster, with less friction — and feeling fulfilled doing it.
Where they are
- MVP launched earlier this year
- Multiple AI agents already deployed
- Six-figure revenue and growing
- Large roadmap ahead — the surface has barely been scratched
The role
My client is looking for a Founding Front End Engineer who wants ownership, impact, and pace. This role is ideal for someone who:
- Takes deep pride in their craft
- Is genuinely product-obsessed
- Enjoys complexity and modern frontend technologies
- Thrives in fast-moving, high-ownership environments
- Wants to help define both the product and the engineering culture
This is a build-from-the-ground-up role, not incremental feature work.
What you’ll do
- Architect, design, and build high-performance React applications
- Create intuitive, elegant, and visually engaging user interfaces
- Collaborate closely with product and design to balance feasibility and aesthetics
- Build reusable, scalable frontend components and libraries
- Leverage AWS-managed services (e.g. S3, CloudFront, Cognito) for secure deployment
- Write clean, maintainable, well-documented code
- Own code quality through reviews and testing (unit, integration, E2E)
- Identify and eliminate performance bottlenecks
- Apply frontend security best practices and industry standards
What they’re looking for
- Strong experience with modern React and frontend tooling
- High engineering standards and attention to detail
- Comfort operating with ambiguity and ownership
- Ability — and desire — to move fast without sacrificing quality
- A collaborative mindset: success is shared
