Mobile App Developer - Ecosystem Lead

We are looking for a practical, hands-on Mobile App Developer to take ownership of our native mobile estate and lead the evolution of our mobile-first product strategy.

This is not a “quiet life” front-end role. You will be our primary permanent mobile specialist in a small, fast-moving team of mainly Python engineers. You’ll be highly visible, trusted with real ownership, and expected to make decisions that directly shape our product direction.

The Role

Your first priorities will be:

1. Maintaining and enhancing our existing Android app
2. Building and launching the equivalent functionality as an iOS app

Following this, you will:

• Help redesign and modernise the web front end of our existing product
• Contribute to the planning and technical design of our next mobile-first product, which will likely also require a supporting web application

This role blends hands-on development, product thinking, and collaboration with stakeholders. You’ll work closely with backend engineers, product leadership, and occasionally clients to ensure our tools are intuitive, high-performing, and genuinely useful.

Your work will have visible impact across advice-giving organisations and the wider public and third sector in the UK.

Key Responsibilities

Mobile App Development (Primary Focus)

• Maintain, refactor and enhance our existing Android application, including design of user experience within the app.
• Design and develop our new iOS app, mirroring Android functionality across in a scalable and maintainable way
• Improve app performance, reliability and usability
• Contribute to architecture decisions for a mobile-first product ecosystem
• Support CI/CD pipelines and manage releases for app stores

Web Front-End Development

• Redesign and modernise the web front end of our existing platform
• Work with backend engineers to integrate APIs effectively
• Establish and refine UI/UX best practices across mobile and web
• Contribute to a cohesive cross-platform design system

Product & Delivery

• Participate in agile ceremonies and technical discussions
• Contribute to architecture and tooling decisions
• Support consultancy tenders and provide meaningful technical input where required
• Occasionally engage with clients to understand use cases and solve problems

About You

We’re looking for someone who is confident in mobile development and excited by ownership.

Essential

• Strong experience in Android development (React Native and Kotlin preferred)
• Experience building or maintaining iOS apps (React Native and Swift preferred) — or strong willingness to transition from Android to iOS
• Solid understanding of mobile app architecture and lifecycle management
• Experience integrating REST APIs
• Familiarity with Git, CI/CD pipelines, Docker and modern DevOps practices
• Experience with HTML, CSS and a modern web framework (e.g. React or similar)
• Comfortable working autonomously in a small, collaborative team

Desirable

• Experience with cross-platform approaches (e.g. React Native)
• UI/UX sensibility and ability to implement wireframes into production-ready interfaces
• Experience contributing to consultancy bids or technical proposals
• Exposure to backend technologies such as Python or Rust

What Success Looks Like

Within your first 6–9 months, you will:

• Have stabilised and improved the Android app
• Delivered a functional iOS version
• Helped modernise the web front end
• Contributed to the technical direction of our next mobile-first product

Salary & Benefits

• Salary: £65k
• Fully remote (with one in-person team meeting per quarter in various UK locations)
