The organisation builds large‑scale, consumer‑facing platforms used by hundreds of millions of users worldwide, with a strong focus on quality, long‑term maintainability, and responsible AI‑assisted development.
This role sits within a financial products marketplace that partners with major financial institutions to deliver personalised consumer experiences. The position is ideal for a senior‑level engineer who values engineering judgement, thoughtful architecture, and technical leadership over speed alone.

  • Collaborate closely with product, design, and engineering partners to shape solutions and evaluate technical trade‑offs
  • Architect and build frontend‑leaning, full‑stack systems that are modular, composable, and resilient to change
  • Champion performance, reliability, and maintainability in AI‑assisted development environments
  • Apply functional programming principles and immutability to reduce side effects and improve system clarity
  • Lead the effective use of AI agents for prototyping, refactoring, and exploration while ensuring production‑grade outcomes
  • Drive a robust automated testing strategy across unit, integration, UI/component, and end‑to‑end layers
  • Provide technical leadership through mentorship, delegation, and high‑quality code reviews

Must‑Have Qualifications

  • Bachelor's degree in Computer Science, Engineering, or a related field
  • 8+ years of experience building production web applications, including senior‑level ownership
  • Prior experience operating at principal, lead, or staff engineer level
  • Expert proficiency with TypeScript and React, including server‑side rendered frameworks such as Next.js
  • Strong understanding of functional programming concepts and immutability in modern frontend systems
  • Advanced knowledge of automated testing strategies and CI‑driven feedback loops
