As a Senior Frontend Engineer, you’ll play a key role in shaping and delivering the web experience used by millions of customers worldwide.
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.
You won’t just build features – you’ll help define what’s worth building and how to deliver it effectively :

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
-

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

“What really blew me away was how genuine and earnest everyone is. There is no “you’re on your own” mentality, I had the opportunity to learn the ropes at my own pace, observe, ask questions and find out how to optimize things to work based on my preferences. My team especially, is helping me relearn what a healthy work relationship looks like. We support each other and there’s no gatekeeping on projects, technique or skill.”
