About the Role

As a Senior React Native Engineer, you will take ownership of the day-to-day development of an existing mobile application available on iOS and Android. You will work directly with the current developer, becoming the most experienced mobile engineer on the team and helping remove development bottlenecks.

You will play a key role in improving code quality, stability and delivery speed within an application built largely using AI coding tools. The position requires someone who can work independently, establish engineering standards and take responsibility for delivering reliable mobile experiences.

This is a remote opportunity with a UK-based company, working UK hours for 45 hours per week. Occasional additional hours may be required during urgent situations and will be paid separately.

Responsibilities

• Take ownership of day-to-day development of the existing React Native application built with TypeScript and Expo, reducing dependency on the current developer
• Improve code quality, application stability and engineering standards within a codebase developed largely using AI coding tools, helping the team deliver new features faster
• Build, maintain, test and release mobile application features across iOS and Android using Expo EAS
• Test application functionality on physical iPhone and Android devices
• Migrate historical application data from Supabase to PostHog, ensuring reliable data transfer
• Support product data analysis to help the team understand application data
• Maintain and extend existing hard paywall and subscription flows using Superwall, ensuring they remain functional during builds and releases
• Integrate third-party SDKs and services, including integrations such as Instacart
• Independently manage assigned development work from scope clarification through implementation, testing and release, with minimal in-house technical guidance

Requirements

• 5+ years of professional software engineering experience, with the ability to work independently and take ownership of production development work
• 5+ years of hands-on React Native experience, including recent development and maintenance of production mobile applications
• 5+ years of experience with TypeScript and React, demonstrating strong proficiency in hooks, component design, navigation and state management
• Recent production experience using Expo and EAS to build and release mobile applications
• 5+ years of mobile delivery experience across iOS and Android, including shipping and maintaining features on both platforms and owning the release process
• Experience with Supabase or a comparable backend-as-a-service platform, supporting applications without a separate backend
• Experience performing reliable data migrations between systems using SQL and scripting, alongside analysing product data
• 3+ years of API and SDK integration experience, implementing reliable asynchronous flows with loading states, failure handling and retries
• 2+ years of mobile debugging and testing experience, including diagnosing crashes, performance issues and platform-specific bugs on real devices
• Ability to test application functionality on both a physical iPhone and Android phone. Devices can be provided if required
• Ability to become productive quickly within an existing codebase, clarify requirements and independently deliver work through release without senior technical oversight
• Fully fluent written and spoken English, with the ability to ensure application copy and recipes read naturally
• Ability to raise engineering standards, take initiative and help the team deliver faster without waiting for direction
• Flexibility to support occasional urgent situations requiring additional working hours beyond the standard 45-hour week, paid separately

Nice to Have

• Experience with paywalls, subscriptions and in-app payments, ideally using Superwall, RevenueCat, StoreKit or Google Play Billing
• Experience with PostHog or other product analytics platforms
• Experience setting up crash reporting and production monitoring from scratch using tools such as Sentry or Crashlytics
• Awareness of mobile application security practices
• Experience improving early-stage, AI-built or prototype codebases into stable, production-grade applications
• Experience implementing camera or photo uploads, share sheets, deep links or content import functionality
• Experience with native iOS or Android debugging
• Experience developing grocery, meal planning or consumer shopping applications

These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
