Senior IOS Engineer - Super

About the role

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 and is growing to support an ambitious roadmap including new navigation patterns, deeper product integrations, and full codebase modularisation.

What you'll do

• 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

What you'll need

• 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

What they offer

• Work with SumUppers globally on large-scale fintech products from our Berlin office (office-first setup)
• Virtual Stock Option programme to own a stake in SumUp's future success
• Dedicated annual L&D budget of €2000 for conferences and career development
• Corporate pension scheme with up to 20% matching of contributions
• 28 days of paid leave plus public holidays and special leave days
• Additional benefits including Urban Sports Club subsidy, Kita placement assistance, subsidised office lunches, and 1-month sabbatical after 3 years
