Senior Frontend Developer

• Location: London, hybrid. 3 days on-site through probation, then 2 days on-site following,

Our client is a business building point-of-sale and payments technology for high-volume, high-footfall venues, the kind of places that take thousands of transactions in a few hours. They're scaling fast and want a Senior Front-End Developer to own the front end across their products.

Non-Negotiables

• React
• Senior front-end experience, still hands-on in the code
• Component-driven front-end architecture
• Mentoring one or two developers (formal people-management experience not required, but welcomed)
• Strong technical decision-making under pressure

What You'll Work With

• Portal and mobile ordering products
• Design system and shared component library
• Payment flows and real-time data integrations
• Automated testing, CI/CD, and performance monitoring

Nice to Haves

• TypeScript
• React Native for mobile apps
• Node.js, Express, MongoDB, or PostgreSQL
• Background in payments, event tech, hospitality, or retail
• Coming from a competitor or a similar POS / payments platform

Why Join

You own the front end outright: the architecture, the design system, the standards the code is written to. The business is scaling, so what you ship now shapes the product for years, and you see it in the field the moment the gates open.

The management load is light. You'll mentor one or two developers, no more, so this is a chance to grow into technical leadership without stepping away from building. A strong senior who is almost there suits this better than someone who already runs a large team.

It suits someone who wants autonomy and accountability over process. If you need heavy structure and long sign-off chains, this isn't the seat.
