Job description

Lead Front-End Developer | React & TypeScript | POS & Payments Platform

• Location: London, hybrid. 2-3 days on site
• Permanent, full-time

Our client builds point-of-sale and payment technology for busy, high-volume venues, the systems that keep queues moving when thousands of people all want to pay at once. It handles mobile and fixed tills, offline transactions, fast payouts, and real-time reporting, and they want a Lead Front-End Developer to own the frontend across the whole product.

You will set the front-end architecture across their portal and mobile ordering products, mentor a small team, and own the calls on tooling, standards, and release pipelines. You will work in React and TypeScript, sit close to product and design, and integrate APIs, payment flows, and live data with the backend team. It is a startup, so you will balance speed against quality every day.

Non-Negotiables

• Senior or lead front-end experience, deep and hands-on in React
• Team-lead or people-management experience
• Component-driven architecture and state management (Redux, Context API)
• 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

• React Native for mobile apps
• Node.js, Express, MongoDB, or PostgreSQL
• Background in payments, event tech, hospitality, or retail

Why Join

You own the front end outright: the architecture, the design system, the standards the team codes 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.

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