The Mobile Platform Squad is the backbone of SumUp's iOS engineering — we build and maintain the foundation that every iOS feature team relies on to ship fast, confidently, and at scale.
We're a small, high-impact team that sits at the intersection of infrastructure, developer experience, and engineering excellence. Our work isn't visible to merchants directly, but it's felt by every iOS engineer at SumUp every single day — through faster build times, smoother CI/CD pipelines, healthier codebases, and better tooling.
With significant investment in SumUp's mobile products, we're on a mission to empower feature teams to deliver world-class experiences without being slowed down by platform friction. That means building robust internal frameworks, evolving a mature and complex codebase, and acting as a trusted partner to mobile engineers across the organization.
Our engineering culture is built on autonomy, collaboration, and craft. We move with purpose, share knowledge openly, and believe that great platform work is what makes great product work possible. If you're someone who finds deep satisfaction in enabling others to do their best work — you'll feel right at home here.
Experience with modularized codebases, internal tooling, or Ruby scripting
