Senior Mobile Engineer (Food Tracking)

HEY THERE We’re looking for a Senior Mobile Engineer to join the Food Tracking squad at Yazio, the team building the core experience of our product. This includes daily food tracking, AI-driven insights, and features used by millions every day. You are a key part in shaping the Food Tracking squad, leveraging our Kotlin Multiplatform (KMP) stack to deliver high-impact solutions for iOS and Android users. You join a cross-functional team partnering closely with Product Managers, Designers and Analysts. This role is 100% remote and open to candidates based in Germany, Spain, Portugal, or the U.K. YOUR MISSION The Food Tracking squad is entering a new phase. From AI-driven features to deep personalization to help users lead a healthier life. Your mission is to shape the future of our squad with your technical expertise. Own Features End-to-End. You take ideas from a technical design to a polished, deployed feature. You are responsible for writing clean, maintainable code, ensuring high quality, and monitoring the impact of your work in production. Lead Migration to KMP: You assess, document and plan the migration of our complex domain from iOS/Android platform code to KMP-first code—while continuing to ship features to our users. Integrate AI Features: Together with the backend team, you bring scaleable AI-powered features to the app and evaluate best practices to ensure a great user experience. Partner with Product and Design. You won't just be handed tickets. You are a key contributor to the why and what by assessing new technical areas, weighing trade-offs, and helping shape a roadmap that is both ambitious and achievable. Elevate the Team. You act as a mentor for other engineers, leading by example with thoughtful code reviews and improving team processes without being asked. YOUR PROFILE We're looking for a seasoned engineer who is passionate about the craft but even more passionate about the impact their code has on users. Expert in Modern Mobile Development. You have significant experience building native mobile apps on Android with Kotlin and Compose, ideally with KMP. Experience on iOS with Swift and SwiftUI is a huge plus as well as the willingness to expand ownership across both ecosystems. End-to-End Ownership. You have a track record in organizing delivery of features end-to-end. AI Adopter. You're comfortable using AI tools to automate your daily workflows and achieve results while maintaining a high bar of quality and safety. Experience in integrating and shaping AI-driven features in production environments is a huge plus. Pragmatic. You know how to build the smallest piece fast to achieve results. You know what to build first and what to leave for later. You have high standards for code quality and leave it better than you found it even when things move quickly. True Product Engineer. You are obsessed with the user experience and the "why" behind what you're building. You're comfortable with product metrics and are driven to see your work make a measurable impact. Excellent Communicator. You can clearly articulate complex technical ideas to both technical and non-technical partners. You’re comfortable documenting technical topics in written form to your peers.
