About the Role
As a senior technology leader, you will be responsible for driving the strategy, architecture, and technical direction of our modernized cross-platform application ecosystem.
This role blends architectural excellence, hands-on engineering, and cross-functional leadership to unify iOS, Android, and backend interfaces into a scalable Kotlin Multiplatform architecture.
You will lead modernization efforts, establish engineering standards, guide teams through complex technical decisions, and partner closely with product and design stakeholders to deliver a world-class, high-performance app experience.
What You'll Do
Define and own the Kotlin Multiplatform (KMP) strategy and roadmap across iOS & Android teams.
Lead technical steering committees, architecture reviews, and cross-functional planning sessions.
Identify emerging technologies and frameworks to future-proof the mobile ecosystem.
Design and implement a scalable Kotlin Multiplatform (KMP) architecture to unify Android and iOS app development.
Establish architecture blueprints, coding standards, and reusable libraries.
Write production-level code in Kotlin, Compose Multiplatform, and SwiftUI - balancing speed and maintainability.
Work closely with Android/iOS engineers to migrate existing features into shared modules.
Drive modularization, networking, and persistence layers using Ktor, SQLDelight, and shared view models.
Introduce performance benchmarks, observability, and automated quality gates.
Collaborate with product and design teams to build beautiful, performant user experiences.
Set up lightweight CI/CD pipelines and code quality gates that work for a small, nimble team.
Mentor mobile engineers transitioning into KMP development and create internal best practices.
Stay plugged into the latest Kotlin and multiplatform ecosystem updates, experimenting and prototyping fast.

What We're Looking For
10 + years of Software Engineering experience (Android and/or iOS) with at least 5+ years with KMP expertise.
Serve as the technical authority and escalation point for complex design, architecture, and performance challenges.
Mentor engineers across iOS, Android, and Backend to develop strong Multiplatform expertise.
Conduct design reviews, code reviews, and architecture walkthroughs.
Build an engineering culture centered on excellence, ownership, curiosity, and continuous improvement.
Strong Kotlin skills - experience with coroutines, Ktor, SQLDelight, and Gradle builds.
Hands-on experience with Kotlin Multiplatform (KMP / KMM) in production or POC stages.
Understanding of Jetpack Compose and SwiftUI for modern UI architecture.
Comfortable with RESTful APIs, offline storage, and sync mechanisms.
Experience building apps end-to-end - from architecture to deployment.
Startup DNA: you can move fast, prioritize, and deliver with limited process.
Excellent communication and mentoring abilities - you'll be the go-to for multiplatform questions.
Leadership & Strategic Skills
Proven experience leading architecture strategy for large-scale mobile systems or modernization programs.
Ability to influence engineering direction across multiple teams and functions.
Strong decision-making skills, balancing trade-offs between speed, risk, and scalability.
Ability to simplify complex problems and communicate solutions effectively to executives and engineers alike.
Strong mentoring mindset and ability to uplift engineering talent around you.
