Senior Kotlin Multiplatform Engineer | Remote Europe (UTC 0 to +6) | Cryptocurrency

About the Company

Albert Bow is partnering with a product-led team building multi-platform apps used by millions of users. Their focus is on creating a truly shared codebase across Android and iOS without sacrificing performance, usability or native behaviour. You’ll join a small, senior engineering group who care about clean boundaries, high-quality code and scalable architecture.

About the Role

This role goes beyond writing Kotlin. You will own the Multiplatform strategy end to end, defining what belongs in shared modules and what must stay native. You’ll make architecture decisions that prevent tech debt, reduce debugging overhead and keep delivery fast and clean. Your work will directly shape how the team scales.

What You’ll Do

• Design the shared architecture and decide what is native vs common
• Build and optimise the KMP build system and dependencies
• Solve complex interoperability challenges with Swift and Objective C
• Ensure structured concurrency and performance across Android and iOS
• Act as the technical gatekeeper for standards, testing and documentation
• Mentor engineers transitioning into Kotlin Multiplatform

What You’ll Bring

• Strong Kotlin experience and confidence writing production Swift
• Deep understanding of KMP internals, memory models and debugging
• Experience working with Gradle, complex dependencies and CI pipelines
• Pragmatic approach to what should not be shared
• Ability to lead architecture decisions and mentor others

If you are interested please apply with your CV!

Thanks,

Chloe
