This is a hands-on role with strong ownership: you’ll lead complex projects end-to-end, contribute to technical direction, and elevate the team through high standards and mentorship.

Lead development of high-impact features from ideation to production
Make pragmatic trade-offs to balance speed, quality, and scalability
Ship frequently and iterate based on real user data
Drive technical excellence
Write clean, maintainable, and performant code (TypeScript, React, Next.js)
Improve architecture, scalability, and reliability of the platform
Maintain a high bar for testing, monitoring, and code quality
Shape solutions, not just code
Collaborate with Product, Design, and Marketing to define the right problems
Contribute to technical decisions with a strong product and business mindset
Focus on outcomes like conversion, performance, and user experience
Elevate the team
Mentor engineers through code reviews, pairing, and feedback
Share knowledge and promote best practices across the team
Help drive a culture of ownership, pragmatism, and continuous improvement
Collaborate across functions
Work closely with stakeholders to plan, estimate, and deliver work
Communicate clearly on progress, risks, and trade-offs
Contribute to a strong, transparent engineering culture
What we're looking for
Strong experience building production applications with JavaScript/TypeScript and React
Experience with Next.js or modern SSR frameworks
Proven ability to own and deliver projects end-to-end
Comfortable leveraging AI-assisted development tools (e.g. code generation, debugging, documentation, and exploration) to improve productivity, while applying strong engineering judgment to validate outputs and maintain high quality standards
Strong product mindset - focused on user impact and business outcomes
Experience in A/B testing and data-driven optimisation
Solid understanding of performance, SEO, and web best practices
Pragmatic approach to engineering—knowing when to optimise vs ship
Mentoring mindset with strong communication skills
