What the job involves

• We are a mobile-first bank, and our iOS app is a critical part of how customers experience Zopa
• Having recently completed our migration to fully native mobile, we are now focused on making our iOS platform exceptional: fast, reliable, accessible and easy for engineers to build on
• You’ll join our Mobile Platform team, which owns the shared capabilities that underpin the app, including architecture, shared modules, design system, observability, developer tooling and CI/CD
• The team’s role is not to own all technical decisions. It is to help shape the direction of mobile engineering at Zopa, create great developer experiences for our product teams, and make it easier for engineers to focus on customer problems rather than underlying technical complexity
• You’ll also be part of a strong iOS engineering community, contributing to standards, sharing knowledge and helping us continue to mature our native engineering practice
• Partner closely with the Engineering Manager, Principal Mobile Engineer and Head of Mobile Engineering to deliver Zopa’s mobile strategy
• Help shape the technical direction and standards for iOS across Zopa
• Design and evolve shared modules, APIs, architecture and developer tooling that enable multiple teams to build and ship with confidence
• Identify technical risks early, using data, profiling and observability to improve performance, reliability and developer experience
• Stay highly hands-on, delivering production-quality Swift and SwiftUI code across platform and customer-facing product work
• Raise the capability of other engineers through pairing, code reviews, technical discussions and knowledge sharing
• Work closely with Product, Design, Backend and Android colleagues to make well-rounded decisions, influence direction and respect each discipline’s expertise
