Description
Babbel Labs is an AI-first, independent company within the Babbel group, based in Berlin, focused on building the future of language learning. As a Senior iOS Engineer, you will join the Learning Experience teams to build core learning features such as the learning path, exercise player, and real-time speaking practice. You will own the experience end-to-end, shipping it as a distributable Swift package integrated into Babbel's main iOS app, and you will work closely with product, design, and cross-platform engineers. The role emphasizes an AI-first mindset, using coding agents as first-class tools in design, build, test, and review processes. Success is measured by the quality and impact of shipped learning experiences, codebase health, and knowledge sharing.
Requirements
- 5+ years of experience building scalable iOS applications using Swift.
- AI-first mindset: actively embrace AI coding tools, direct agents through feature work, and critically review their output.
- Strong, up-to-date Swift including Swift 6 strict concurrency (actors, Sendable, isolation) and structured concurrency.
- Deep SwiftUI experience and solid grounding in the Apple ecosystem and Human Interface Guidelines.
- Strong opinions on state management and testable architecture, experience with unidirectional-data-flow architecture.
- Testing as a first-class habit: deterministic unit tests, snapshot tests, and CI/CD discipline.
- Experience designing module boundaries, frameworks, or SDKs that other teams consume, ideally as distributable Swift packages.
- Experience designing or consuming evolving JSON APIs and collaborating with contract-first backend teams.
- An eye for good architectural decisions and balancing technical debt against delivery speed.
- Comfort with ambiguity and fast iteration.
- Clear, concise communication and an open mindset for feedback.
- Fluency in written and spoken English.
