The Commerce Engineering organisation is on a mission to build the leading SaaS ecommerce platform.

We work closely with engineering teams across multiple domains, product managers, designers, business stakeholders, and external partners to build a platform where we can easily and securely deliver new and alternative user experiences. Our team brings together people with varied experience and strengths, and we iterate, learn, and build great software together.

What You'll Do

• Build high-quality front-end features using React and TypeScript, with a focus on clarity, performance, and maintainability

• Refactor legacy or complex areas of the codebase to improve readability, testability, and long-term health

• Identify and fix issues across the stack, from front-end behavior to API calls, ensuring solutions are robust and scalable

• Collaborate closely with product managers, designers, and other engineers to define requirements, refine stories, and deliver predictable outcomes

• Provide thoughtful code reviews, offer technical guidance to less experienced engineers, and contribute to a culture of continuous improvement

• Help shape the technical direction of the team through practical suggestions, hands-on implementation, and identifying opportunities to reduce friction or complexity

• Contribute to improving our front-end developer experience, including building tools, testing practices, and performance optimisations

• Ensure technical decisions support our goals of quality, performance, reliability, and security

Who You Are

• You have at least 4 years of hands-on experience building front-end applications with React and TypeScript, and you’ve worked on complex or long-lived codebases

• Education: Preferred Minimum Bachelor's degree in CS, EE, SW, CE, MIS; or equivalent experience

• You write maintainable, well-tested code and care about leaving things better than you found them

• You’re comfortable working in existing systems as much as building new ones, and you enjoy simplifying code, refactoring, and untangling complexity

• You’re a clear communicator who can explain technical details and trade-offs to both engineers and non-engineers

• You take ownership of outcomes, follow through on commitments, and hold yourself to a high standard of reliability

• You enjoy mentoring and supporting others, and you contribute positively to the team’s culture and technical growth

• You stay up to date with modern tools and approaches without being dogmatic. Your goal is to find the right solution, not the trendiest one

• You’re proactive, curious, and comfortable working independently when needed while still being a strong collaborator
