iOS Engineer (up to £150k)

The Role

This company builds the AI workspace that the world’s largest banks and regulated institutions run their document-heavy work inside. They’re growing rapidly, backed by leading investors, and transforming how major financial institutions produce and validate client-ready work.

They’ve shipped everything on the web, but now need a native iOS app — not a wrapper, but a proper, performant experience for iPhone and iPad. You’ll own the entire iOS architecture, from interaction patterns and offline behavior to testing and release. This isn’t just implementing features; it’s defining the mobile future for a product used by global teams.

The Work

• Rebuild existing web products as native iOS experiences, deciding what translates directly and what needs reshaping for mobile.
• Define the entire iOS architecture, including interaction patterns, offline behavior, notifications, and performance standards.
• Own the iOS design system, ensuring coherence and maintainability as the product scales.
• Set up and maintain the testing, observability, and release pipelines for a production-grade native application.
• Collaborate directly with Design, Product, and web engineering teams to adapt existing surfaces without losing their core intent.

What You Bring

• You’ve built and shipped native iOS applications in Swift and SwiftUI, with clear ownership of end-to-end delivery.
• You have strong judgment on mobile interaction patterns and offline behavior, understanding caching, syncing, and graceful degradation.
• You’ve designed iOS architecture that has scaled with a growing team and product, beyond a single, isolated app.
• You’ve owned and maintained an iOS design system, prioritizing its long-term maintainability.
• You’re comfortable adapting complex product surfaces from web to native, working closely with cross-functional teams.
