The Role

We’re looking for a Senior iOS Engineer who is passionate about building a scalable, reliable mobile platform and enabling teams across the organisation to contribute confidently and independently to the FT’s award-winning digital products. You’ll join the Mobile Apps team, a multidisciplinary, cross-functional group focused on delivering an outstanding mobile experience for our world class news. You’ll collaborate closely with engineers, product managers, business analysts and designers to build and evolve a premium mobile application and platform for our customers.

What You’ll Do

• Define and evolve iOS platform boundaries (native vs shared vs web layers)
• Ensure performance, reliability, and UX consistency as contribution scales across multiple teams
• Make architectural trade-offs across native, hybrid and shared approaches
• Identify and address platform risks (performance, memory, app size, offline behaviour)
• Define and enforce native constraints (performance, memory, app size, lifecycle) to protect platform integrity

Contribution Enablement & Guardrails

• Define and evolve guardrails and constraints that enable safe contribution at scale
• Guide teams on how to build within platform boundaries
• Reduce reliance on central ownership through systems and tooling
• Collaborate with teams to improve quality without blocking delivery

Delivery & Engineering Excellence

• Build and maintain high-quality iOS features and platform capabilities where native expertise is required
• Work with hybrid technologies (webviews, shared logic) where required
• Collaborate with cross-functional teams to deliver high-impact outcomes
• Contribute to continuous improvement of engineering practices
• Use automated tooling and systems to ensure high quality outcomes throughout delivery.

What You’ll Bring

• Deep expertise in Swift and iOS platform internals (performance, lifecycle, memory)
• Strong architectural judgement across native, shared and web approaches
• Experience working on large-scale mobile applications with multiple contributors
• Ability to define platform boundaries and make pragmatic trade-offs
• Experience enabling teams to contribute safely without central ownership
• Strong problem-solving skills across complex technical systems
• Excellent communication and ability to influence across teams
• Experience working with Kotlin Multiplatform or shared code approaches
• Experience working with Apple’s in-app purchase ecosystem (StoreKit), including subscription models, entitlements, and edge cases (restoration, retries, offline behaviour)
• Experience in hybrid app architectures (webviews, JS integration)
• Familiarity with observability and performance monitoring tools
• Experience influencing engineering practices across teams
• Experience supporting teams through architectural or platform transitions
