front end developer jobs in London

Mid-Level Software Engineer (Data & Infrastructure)

About the role

We’re a close-knit engineering team building and running the internal products that 700+ employees across 70+ locations depend on every day; from our Laravel-based ops platform, to Azure data pipelines, mobile apps built with React Native / Expo, and a new greenfield platform in early development.

We’re looking for a Mid-Level Software Engineer who leans towards the mobile and front-end side of what we build.

You’ll be a hands-on contributor to our React Native / Expo apps; used daily out in the field; and work across the React and Laravel that backs them.

This is a hands-on, ship-it role with real influence. With no project managers, you’ll take features from idea through to production yourself, and you’ll see your work live quickly.

What you’ll be doing

• Build and evolve React Native / Expo mobile apps; features, fixes, releases (EAS / OTA), and keeping them stable on real-world devices
• Build front-end features in React and TypeScript
• Work across the Laravel / PHP backend; APIs, auth, and endpoints your apps consume
• Own work end to end; scope, design, build, ship and demo
• Write clean, tested code and contribute through code reviews
• Use our Azure environment to deploy and run what you ship
• Help shape the mobile experience of a greenfield platform
• Contribute to building AI features into products, not just using AI tools.

What we’re looking for

• A few years’ experience in front-end or full-stack engineering
• Strong React Native (ideally Expo); experience shipping apps to production
• Strong React and modern TypeScript / JavaScript
• Confident PHP / Laravel capability (core to the role)
• Solid SQL and data understanding
• Experience working with a cloud platform (Azure preferred)
• Comfortable owning work from requirement to delivery
• Curious, self-driven, and passionate about the craft
• Confident using AI tools; with real understanding behind the code
• Up for building AI into products, not just using it.

Bonus points for:
Filament, native mobile work, push notifications / offline sync, Astro, OAuth / SSO, integrations, or queue systems

What you’ll get

• A central role on the apps and front ends 700+ people rely on daily
• A fast-paced environment where your work hits production quickly
• A broad stack across mobile, web, data, and cloud
• Real influence on what gets built and how
• A clear path to senior engineer
• The chance to help shape a greenfield platform from early stages.

How we hire

No leetcode, no algorithm trivia.

• A practical feature build in our stack (mobile / front-end focused)
• A conversation walkthrough of your approach.

We care about how you think and build; not how many puzzles you’ve memorised.
