Senior Mobile Engineer; Android Focus); Cross platform; EV Charging

Location: Liverpool Street Salary: Up to £80,000 + bonus (DOE)

We're working with a fast-growing, well-backed business in the EV charging space. who are one of the UK's fastest-moving Charge Point Operators. Having scaled from a handful of engineers to a genuinely cross-functional tech team over the past few years, they're now looking for a Senior Mobile Engineer to join their team.

This role will be cross platform although the main focus will be Android (80-90%). The team already has 2 x iOS Engineers so this will be to take the reigns of all things Android.

This is a rare chance to work at the intersection of hardware and software. Unlike most mobile roles, which sit purely in the app layer, here you'll be building the mobile experience that sits directly on top of real-world charging hardware.

You'll be joining at a pivotal moment: the team is completing a major re-platform of the core app this year, before shifting focus to an exciting roadmap of new features as the business expands into new UK regions and works with local authorities across the country.

If you're motivated by tech that has a genuine, visible impact (cutting carbon emissions, improving air quality, and building the infrastructure the UK needs for the shift to electric) this could be the role for you.

• Developing and maintaining high-quality native mobile applications for iOS and Android (Kotlin-heavy... this role skews strongly toward Android)
• Working alongside 2 x senior mobile engineer (iOS-leaning) but focusing on Android (with some iOS)
• Optimising app performance for speed, memory usage, and battery efficiency
• Integrating with REST/GraphQL APIs for real-time data synchronisation
• Collaborating closely with a genuinely cross-functional team
• Writing and maintaining automated tests to ensure app stability and quality
• Contributing to a strong pipeline of new, high-value features as the business scales

• Strong commercial experience building and shipping native mobile apps, with particular strength in Kotlin/Android (80%)
• Comfortable working with Swift/iOS as needed (20%)
• Familiarity with mobile performance profiling and debugging tools
• Experience integrating mobile apps with backend APIs for real-time data
• Solid grasp of Agile ways of working

A close-knit, ~12-person tech function that works deliberately cross-functionally.

The culture is collaborative, driven, and refreshingly free of ego.

Genuine progression exists and there is lots to be excited about for their future - They are just starting their journey!
