About the Opportunity

YAZIO is on a mission to transform the world through healthy eating, and we're looking for a Senior Mobile Engineer to join our Food Tracking squad. This is the team building the core experience of our product—daily food tracking, AI-driven insights, and features used by millions every day. If you're passionate about crafting high-impact mobile experiences and want to shape the future of health tech, this is your chance.

This role is 100% remote and open to candidates based in Germany, Spain, Portugal, or the U.K.

The Role & Impact

As a key member of the Food Tracking squad, you'll leverage our Kotlin Multiplatform (KMP) stack to deliver high-quality solutions for both iOS and Android. You'll work in a cross-functional team alongside Product Managers, Designers, and Analysts, and you'll have the opportunity to:

Own Features End-to-End: Take ideas from technical design to polished, deployed features. You'll write clean, maintainable code, ensure high quality, and monitor your work's impact in production.
Lead Migration to KMP: Assess, document, and plan the migration of our complex domain from platform-specific code to KMP-first, while continuing to ship features to users.
Integrate AI Features: Collaborate with the backend team to bring scalable AI-powered features to the app, evaluating best practices for an exceptional user experience.
Partner with Product and Design: Contribute to the 'why' and 'what' by assessing technical areas, weighing trade-offs, and helping shape an ambitious yet achievable roadmap.
Elevate the Team: Mentor other engineers, lead by example with thoughtful code reviews, and proactively improve team processes.

Key Focus Areas

Modern Mobile Development: You have significant experience building native Android apps with Kotlin and Compose, ideally with KMP. Experience with iOS (Swift/SwiftUI) is a huge plus, as is a willingness to expand ownership across both ecosystems.
End-to-End Ownership: You have a track record of organizing feature delivery from start to finish.
AI Adopter: You're comfortable using AI tools to automate workflows and maintain high quality. Experience integrating AI-driven features in production is a big plus.
Pragmatic: You know how to build the smallest piece fast to achieve results, prioritize effectively, and maintain high code standards even in fast-paced environments.
True Product Engineer: You're obsessed with user experience and the 'why' behind what you build. You're comfortable with product metrics and driven to see measurable impact.
Excellent Communicator: You can clearly articulate complex technical ideas to both technical and non-technical partners, and you're comfortable documenting technical topics in writing.

Technical Stack

We believe in Kotlin Multiplatform and use it heavily in our modularized monorepo. We share as much code as possible outside the UI layer, while building fully native UI using Compose on Android and SwiftUI on iOS. We use libraries like:

kotlinx.coroutines
kotlinx.serialization
Ktor
SQLDelight
Metro for dependency injection
