iOS engineer in design systems

Описание:

As an iOS Engineer on the Design System team, you'll translate SumUp's design language into a reusable, easy-to-use library of UI components and experience patterns — empowering product teams to build cohesive, accessible user experiences at scale.

Задачи:

• Shape the core experience for both users and developers interacting with SumUp's iOS ecosystem
• Collaborate closely with product and design teams to build components that are maintainable, consistent, and beautiful
• Embed accessibility best practices into every component — from content descriptions and touch target sizing to color contrast and dynamic type
• Provide hands‑on technical guidance to product teams to deliver on company priorities, including the upcoming support for landscape orientation
• Review code contributions, enforce design system conventions, and mentor engineers on best practices for reusable UI development
• Lead the migration of legacy UIKit-based components to SwiftUI while maintaining system stability
• Proactively identify and address technical debt to uphold a high bar for engineering excellence and codebase health

Требования:

• Bring 3+ years of professional iOS development experience, ideally on large‑scale or consumer‑facing applications
• Are fluent in Swift, with deep hands‑on knowledge of both SwiftUI and UIKit — and a clear view on when and how to use each
• Bring experience building or contributing to a design system, component library, or shared UI framework, and understand what it takes to make components truly reusable and scalable
• Take pride in crafting accessible user experiences — you know your way around VoiceOver, dynamic type, color contrast, and touch target standards, and treat accessibility as a first‑class concern, not an afterthought
• Bring a strong grasp of testing best practices for UI components, including unit tests, snapshot tests, and UI automation
• Are comfortable reviewing code and mentoring peers — you enjoy sharing knowledge, giving constructive feedback, and raising the bar for the whole team
• Are self‑motivated and structured in your working style — you manage your own priorities, communicate clearly in English, and thrive in a cross‑functional, collaborative environment
• Stay genuinely curious about the iOS ecosystem — you follow Apple's releases closely, experiment with new APIs, and are excited to bring fresh ideas back to the team
