Hey there! As a Mobile Staff Engineer, you are the org-wide technical leader for Mobile. You partner with Engineering Managers, Product Managers, and the Platform squad to define and evolve the KMP foundation that powers all squads. Your impact is measured by faster delivery, higher quality, and better developer experience across the entire mobile organization - not by individual feature output. In this role, you will set the technical vision for building, testing, and shipping our Kotlin Multiplatform application at scale. You'll ensure architectural integrity, boost developer velocity, and solve cross-cutting challenges to unblock teams and improve user value delivery. We’re looking for a Staff Engineer ready to multiply their impact across YAZIO’s entire mobile organization. This job is 100% remote and can be based in Germany, Spain, Portugal or the U.K. Your Mission Architectural Vision & Strategy: Define and drive the multi-year technical roadmap for our KMP mobile platform. This includes establishing the core architectural principles, patterns for data flow, modularization, and testing that all mobile engineers at YAZIO will follow. Developer Leverage & Experience: Own and improve the developer experience by optimizing build times, creating robust shared libraries, refining our CI/CD pipelines, and providing tooling that makes writing high-quality code the path of least resistance. Driving Cross-Functional Technical Decisions: As the lead architect and advocate of our mobile platform, you will guide teams toward scalable and maintainable technical solutions.Through mechanisms like RFCs, architecture reviews, and deep-dive design sessions, you will guide teams toward coherent technical solutions and ensure our platform remains scalable and maintainable as we grow. You'll spend less time on day-to-day code reviews and more time shaping the foundational PRs that set new patterns. Mentorship & Influence: You will mentor our Senior engineers across the organization, elevating the technical bar for all of YAZIO. Your influence will be felt through your writing, your technical guidance, and your ability to bring multiple teams to a consensus on complex technical decisions. Our Core Tech Stack Kotlin Multiplatform (KMP) Jetpack Compose (Android) SwiftUI (iOS) Kotlin-Inject(KMP) Dagger (Android) Ktor (KMP Networking) Sqldelight (KMP Persistence) Your Profile Deep Technical Expertise: You have extensive, hands-on experience architecting and shipping complex mobile applications to millions of users, with a significant track record in native mobile development (Android or iOS) and demonstrated expertise in the Kotlin Multiplatform ecosystem. You can debate the intricate trade-offs of different KMP architectural patterns from firsthand experience. Proven Technical Strategist: You have experience defining and executing a technical roadmap for a product area or platform that spans multiple teams. You can point to specific examples where you've reduced technical debt, improved developer velocity, or scaled a system to meet new business demands. Influence Without Authority: You excel at aligning technical stakeholders from different teams and disciplines around a common vision. You communicate complex technical ideas with clarity and conviction, both in writing (e.g., RFCs, design docs) and in person. A Multiplier Mindset: Your proudest achievements aren't just the code you wrote, but how your work enabled and accelerated the work of others. You think in terms of systems and leverage, constantly seeking out opportunities to solve problems for the entire engineering organization, not just one team. AI as a Strategic Lever: You see AI not just as a personal productivity tool, but as a fundamental and growing component of modern software development. You understand what it takes to responsibly integrate AI and have a clear vision for its role in modern engineering, whether through code generation, CI/CD efficiency, or enhanced developer workflows. You’re excited about using AI as a force multiplier for the entire engineering team. Why us?
