Job Context

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 iOS platform while ensuring your team is empowered to maintain and improve a production codebase with a large user base.

Location: Leeds (LS15) or Reading (RG1), on-site.

What You’ll Do

Required skills and experience:

  • Proven ability to lead technical projects and guide engineering teams, including mentoring engineers.

  • Clear communicator who can work well and build relationships with team members of all disciplines and across the business.

  • Comfortable evolving team ways-of-working in dynamic fast-paced delivery environments.

  • Experience developing and refining AI-assisted development workflows and methodologies, with the ability to improve how the team uses the latest tools and practices.

  • Deep expertise in Swift, UIKit, SwiftUI, Combine, XCTest and the broad iOS ecosystem.

  • Experience with legacy codebases and leading transformation.

  • Strong understanding of offline-first architecture and API integration.

  • Understanding of App Store publishing, policies, and release management.

Desirable experience:

  • Track record of evaluating emerging technologies (including AI tooling) and introducing them effectively.

  • Experience with cross-platform approaches (KMP, shared architecture patterns).

  • Experience in SaaS, field service or logistics domains.

What we're looking for in the person:

  • A leader who strives for psychological safety in your team.

  • You celebrate the success of those around you and promote individual and team development outside of pure delivery.

  • You stay current with the iOS ecosystem but apply new tools and patterns as appropriate, not just because they're new.

  • You balance the need to work in legacy codebases whilst modernising and delivering new features.

  • Comfortable making decisions with incomplete information and course-correcting when needed.

What You’ll Bring

  • Experience in iOS development, with strong expertise in Swift and the wider iOS ecosystem (UIKit, SwiftUI, Combine).

  • Proven ability to lead engineering teams and deliver production software, mentoring others and driving technical direction.

  • Experience working with and modernising legacy codebases while continuing to ship features.

  • Strong focus on delivery and execution in fast-paced environments.

  • Experience building scalable mobile applications, including API integration and offline-first architecture.

  • Familiarity with cloud-based environments and modern development tooling.
