Looking for an experienced Lead Front-End Engineer who can combine hands-on development with technical leadership to shape the future of our merchant-first ecosystem. You’ll guide and mentor a growing engineering team while delivering high-quality, customer-focused solutions.

 

You’ll work with TypeScript, React, and modern web technologies to transform our applications into seamless, data-rich experiences. Expect to design and build reusable component libraries, secure payment pages, and portals that delight customers. You’ll be part of a collaborative environment that values curiosity, innovation, and outcomes over outputs.

 

What you’ll do:

 

  • Lead by example while mentoring engineers and setting technical direction.
  • Translate customer needs into modern, scalable solutions.
  • Build and optimise responsive front-end applications.
  • Collaborate across teams to deliver reliable, secure, and high-performing software.
  • Drive best practices in development, automation, and CI/CD.

 

What we’re looking for:

 

  • 10+ years’ software engineering experience with strong JavaScript/TypeScript expertise.
  • Proven front-end product development skills with React (or similar), HTML, CSS/SASS, and build tools.
  • Strong design sense and ability to deliver pixel-perfect interfaces.
  • Experience with REST APIs, OAuth2/OIDC, and data-rich applications.
  • Excellent communication, leadership, and problem-solving skills.

 

This is your chance to join a team that empowers engineers, embraces modern practices, and is committed to building products that solve real-world challenges.
