Senior Mobile Engineer (KMP)

YAZIO

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. OUR CORE TECH STACK We believe in Kotlin Multiplatform and use it heavily in our modularized monorepo. We share as much code as possible outside of the UI layer, while building the 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. WHY US? * An exciting product with millions of users in over 150 countries, driven by our mission to transform the world through healthy eating * A remote-first setup: work 100% from home, join a co-working space, or work abroad for several weeks per year * 30 vacation days to relax and recharge, plus 5 child sick days if your little one needs you * A focus-driven culture that values efficiency over long hours - no overtime expectations, and if it happens, you get that time back! * A high-impact environment where your work drives real change - short decision-making processes and no micromanagement * A team culture where ambition and balance go hand in hand, supported by strong connections - from our fully covered company retreat to team meetups and virtual coffee breaks * Tools and support to do your best work: MacBook, monitor, and €1,000 annual learning budget, plus regular feedback and career development * A truly international team with English as our company language and a shared commitment to growth and well-being - supported by Sunday Supplements and Nilo Health DIVERSITY AND INCLUSION At Yazio, we believe that diversity fuels innovation. We are committed to fostering an inclusive environment where everyone, regardless of gender identity, race, religion, age, sexual orientation, or ability, feels valued and empowered. We celebrate different perspectives and actively encourage individuals from all backgrounds to apply. READY TO JOIN US?

Knowunity

ABOUT THE ROLE Foundation is the team that makes every product team at Knowunity faster, we own the core backend in Go, the Flutter mobile foundation, infrastructure, and the agentic/AI setup that's central to how we ship. We're hiring a Senior Platform Engineer to help define and evolve the systems everything else is built on, and to operate where product engineering and AI tooling meet. You'll work on the systems the rest of engineering depends on, and help shape how AI fits into our day-to-day work. Your Impact * Core backend platform: Design, build, and maintain Go services and the patterns other teams depend on. * Mobile foundation: Own foundational parts of the Flutter app, including shared components, performance, and build tooling. * Developer experience: Drive end-to-end DevEx, CI/CD, local dev, internal frameworks, faster feedback loops. * Infrastructure & operations: Strengthen reliability and operational maturity across observability, and deploys * Agentic & AI infrastructure: Build out how AI tools integrate into our codebase, our workflows, and eventually our product. YOUR BACKGROUND * Multiple years shipping production software at meaningful scale, ideally including time on platform, infrastructure, or core systems work. * Strong background in backend and/or mobile development, depth in one with curiosity about the other. Ideally existing experience in Go and Flutter. * Solid grounding in DevOps, CI/CD, and modern infrastructure practices. * Genuine interest or background in AI, you don't need to have trained models, but you should be excited about agents as a serious engineering surface. * You enjoy fixing the things that slow other people down. You think clearly about tradeoffs, communicate well across teams, and don't need your name on a feature to feel the work mattered.
