Job description

As a Senior Frontend Developer you will be part of our cross-functional Agile development team delivering EDI products. This is a hands-on senior role for someone who can design and build high-quality, maintainable user interfaces while also helping shape the technical direction of the team.

You will work closely with our UX teams, backend developers, product stakeholders, and other engineers to deliver user-friendly features as part of our cloud-native EDI platform. As a senior member of the team, you will be expected to lead by example, mentor other developers, challenge existing approaches where appropriate, and suggest practical improvements to our products, codebase, tooling, and ways of working.

This is a great opportunity for someone who is curious about modern development practices, including the thoughtful use of AI-assisted development tools.

This does not mean replacing sound engineering judgement; it means understanding where AI can help improve productivity, quality, learning, prototyping, testing, documentation, and developer experience.
