Senior IOS Engineer - SuperApp

The Engagement Mission sits within the SuperApp & Web squad - a cross-functional team of engineers, product managers, and designers building the core experience that millions of merchants interact with every day.

This team owns the home screen of the SumUp Business App: the first thing a merchant sees when they open the app, and the surface that connects them to payments, banking, invoicing, loyalty, and more. We’re growing the team because the roadmap is ambitious - new navigation patterns, deeper product integrations, and a full modularisation of the codebase - and we need someone who can hit the ground running and take real ownership from day one., * Build and maintain core iOS features across the home screen, including first-time user experience, quick actions, widgets, the tools section, and upsell and cross-sell channels

• Lead the development of new initiatives end-to-end - from technical design through to shipping - working closely with product, design, and partner engineering teams
• Drive the migration to SwiftUI and contribute to the modularisation of our codebase, improving scalability and developer experience
• Review code, shape technical decisions, and help raise the bar across the iOS chapter
• Collaborate with multiple internal teams to align on feature direction, open pull requests, and deliver in a fast-moving, loosely defined environment

Do you have experience in iOS development?, * Strong proficiency in Swift and SwiftUI, with a track record of building and shipping production iOS features at scale

• Experience navigating and refactoring complex, evolving codebases with a focus on clean architecture (MVVM/MVP)
• Comfortable working in a cross-functional environment where scope isn’t always well-defined and priorities shift quickly
• Ability to take full ownership of initiatives independently - from technical scoping through to delivery - without needing close guidance
• Experience collaborating across teams where you don’t own the product roadmap directly, and are used to aligning with multiple stakeholders to get things shipped
• Strong technical writing skills and a habit of writing clear documentation and thoughtful pull requests
