Lead Mobile Engineer - Android

Lead Mobile Engineer – Leeds (LS15) or Reading (RG1)

We are looking for an experienced Lead Mobile Engineer to join our team working on a complex field‑service mobile application used by engineers across the UK. You will lead the technical direction of our Android platform, guiding a team of developers working on a mature, production codebase with a large user base. The role is on‑site in either Leeds (LS15) or Reading (RG1).

You will drive the technical strategy for the Android platform, mentor the engineering team, design and implement AI‑assisted development workflows, guide fast‑paced delivery initiatives, evaluate emerging technologies, and maintain high code quality and security standards.

• Proven ability to lead technical projects and guide engineering teams, including mentoring engineers.
• Clear communicator who can work well with team members of all disciplines and directly with the business.
• Experience developing and refining AI‑assisted development workflows, with the ability to improve how the team uses the latest tools and practices.
• Comfortable evolving team ways‑of‑working in dynamic, fast‑paced delivery environments.
• Deep expertise in Kotlin and the modern Android stack (Compose, coroutines, MVVM).
• Experience with legacy codebases, including XML Views, Fragments, and Java interop.
• Strong understanding of offline‑first architecture and API integration.
• Familiarity with the broader Android ecosystem (Hilt, Work Manager, Realm, Firebase, Location Services).
• Familiarity with cloud‑based hosting.
• Proven ability to lead technical projects and guide engineering teams.

• Track record of evaluating emerging technologies (including AI tooling) and introducing them effectively.
• Understanding of Play Store publishing, policies, and release management.
• Experience with cross‑platform approaches (KMP, shared architecture patterns).
• Awareness of mobile security best practices, including dependency vulnerability scanning.
• Experience in SaaS, field service, or logistics domains.

You are a leader who strives for psychological safety in your team, celebrating the success of those around you and promoting individual and team development outside of pure delivery. You balance working in legacy codebases while modernising and delivering new features, staying current with the Android ecosystem, and applying new tools and patterns as appropriate. You make decisions with incomplete information and course‑correct when needed.
