  • 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

  • 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
