Founding Full-Stack Engineer (Greenfield Digital Banking)
Central London | 4 days onsite | Full-time
£90,000 – £100,000 + 15-20% bonus

We’re working with a highly successful, family-owned international private bank to hire a Founding Full-Stack Engineer for a brand new, greenfield digital banking build based in Central London.

This is a rare opportunity to join right at the beginning of a newly formed product team and help build a next-generation digital banking experience from first principles deliberately outside of legacy systems.
The environment is genuinely “startup-style” (small team, high ownership, fast delivery), but backed by serious scale, long-term investment, and a strong focus on quality, stability and client trust.

The role
As one of the first engineering hires, you’ll play a key part in shaping:

• the technical foundations
• engineering standards
• architecture and system design
• how the team builds and ships product

You’ll work closely with Product and Design, delivering secure, high-quality digital experiences for high-value clients and complex workflows.

What you’ll do

• Design, build and maintain end-to-end features across frontend and backend
• Architect scalable, secure and maintainable systems for private banking / institutional use cases
• Own key technical decisions, balancing delivery speed with long-term quality
• Build APIs, services, data models and modern web experiences
• Establish high standards of engineering quality through testing, reviews and automation
• Contribute to platform foundations, shared components and internal tooling
• Embed security, performance and resilience best practices into everything you ship
• Help define engineering standards and ways of working as the team grows

What we’re looking for

• 8-12+ years’ experience as a full-stack or senior engineer owning production systems
• Strong experience building modern web applications across frontend and backend
• Frontend expertise with modern frameworks (React, TypeScript or similar)
• Strong backend experience (Node.js, Java, Python or similar)
• Solid understanding of APIs, architecture, databases and cloud infrastructure
• Exposure to CI/CD and modern DevOps practices (containers, Kubernetes, automation)
• Comfortable being a technical owner in open-ended / ambiguous environments
• A builder mindset – pragmatic, delivery-focused, and quality-led
• Experience in financial services / fintech / regulated environments is beneficial but not essential
• Strong awareness of security, privacy and compliance considerations is highly valued

Why this opportunity stands out

• Genuine greenfield build with meaningful ownership from day one
• Founding hire in a small, high-calibre team
• Startup-style delivery with the backing of a global financial institution
• Direct access to decision-makers and influence over product direction
• Quality-first culture focused on trust, stability and long-term value
• Competitive salary + strong bonus + benefits
