The role

You'll work on our iPad app that runs natively on iPad Air M4 hardware. The app is built with SwiftUI and the Composable Architecture (TCA). Whether you already know TCA or are excited to learn it, you'll own features end-to-end, from state management to pixel perfect UI, and ship code that runs in live venues where speed and reliability aren't nice to haves - they're non negotiable.

What you'll do

Build and maintain features in our iPad self checkout app using SwiftUI and TCA
Design clean, testable feature modules - managing state, handling side effects, and integrating external dependencies
Work closely with our backend, AI/ML, and hardware teams to integrate on device recognition, payment flows, and real time data sync
Write thorough tests - our architecture makes features highly testable, and we make the most of that
Contribute to architectural decisions and help shape the codebase as the team grows
Debug and optimize performance for high throughput, real world environments
Participate in code reviews and help maintain a high bar for code quality

What you'll bring

Strong experience building production iOS apps with Swift and SwiftUI
Experience with the Composable Architecture (TCA) is a big plus; if you haven't used it yet, a strong Swift developer curious about modern architecture is fine
Solid understanding of state management and how to keep side effects under control
Comfort working with hardware integrations (payment terminals, peripherals) is a plus
An eye for clean, maintainable code and well tested features
Self driven and comfortable with ownership - you don't wait for permission to fix things
Good communication skills in English; German is a bonus but not required

Nice to have

Experience with on device ML / Core ML
Familiarity with Point Free's broader library ecosystem (swift dependencies, swiftui navigation, swift custom dump)
Experience building apps for kiosk or POS environments
Contributions to open source Swift projects

Competitive salary and company pension
A rooftop BBQ in Osnabrück or a WeWork in the heart of Boston - two offices worth showing up to
A small, sharp team where your work ships to real venues and real users
