More Than Just A Job
We need your help building a scalable and maintainable front end ecosystem to help propel a standalone project within one of the UK's most loved start-ups forward. As a proud B-Corp we focus on using business as a force for good. We do this by balancing out people and planet with profit. For every Mindful Chef recipe box bought we donate the equivalent of a school meal to a child in a less developed country (over 20 million meals donated and counting...) and we have also pledged to go Net Zero by 2030 but there are so many other initiatives that we would love to tell you about!
What we are looking for
We need a skilled React developer to take complete ownership of an existing branded web application and mobile app ecosystem. This is a hands-on role where you'll be responsible for maintaining and enhancing both a production Next.js web application and an Expo-based iOS/Android mobile app, both connecting to a Rails API backend. You'll be stepping into well-structured codebases with modern tooling already in place, but you need to be confident enough to make them your own.
You are
Confident with Next.js and React, able to work with existing code and build new features from scratch
Experienced with React Native and Expo for iOS/Android development
Comfortable communicating with non-technical people about technical requirements and project timelines
Experienced with TypeScript and modern frontend development practices
Someone who takes ownership - you'll be the go-to person for both web and mobile platforms
Pragmatic about getting things done, whether that's fixing bugs or shipping new features
Familiar with Heroku deployments and managing production applications
A problem-solver who enjoys working with existing codebases and making them better
You will
Take complete ownership of both a Next.js web application and Expo mobile app that are already serving real customers
Work with the team to understand the project's needs and prioritize feature development across web and mobile
Maintain and enhance the integration between the frontends and Rails API backend
Deploy web updates to Heroku and manage mobile app releases through app stores
Write tests using the existing testing setups (Vitest/Playwright for web, Jest for mobile)
Handle communication, including progress updates and technical explanations
Identify and implement improvements to performance, user experience, and code quality across platforms
What you'll be working with
Web: Next.js 15 with TypeScript and Tailwind CSS
Mobile: Expo with React Native, NativeWind (Tailwind for RN), and Expo Router
Shared: XState for state management, same Rails API backend
Authentication system using NextAuth.js (web) and Expo SecureStore (mobile)
Testing suites: Vitest/Playwright (web), Jest (mobile)
Deployment: Heroku (web), EAS Build for app stores (mobile)
Modern tooling and shared utilities across platforms
This isn't a greenfield project - you're inheriting applications that work, but need someone to take them forward. If you're the kind of developer who enjoys taking responsibility for entire platforms and can work across web and mobile, this could be perfect for you.
