We're looking for a Mobile Software Engineer (SDK) to help build and evolve a cross-platform SDK used across mobile and web applications. This is a hands-on role where you'll develop high-quality SDK features, improve developer experience, and ensure reliable releases through robust automation and CI/CD practices.

You'll work closely with a highly technical engineering team to design scalable solutions, support external developers with SDK integrations, and contribute to the architecture of a client-facing product. Alongside writing clean, maintainable code, you'll help shape technical decisions, improve documentation, and leverage AI-assisted development tools to deliver high-quality software efficiently.

Requirements

  • 3+ years of software engineering experience, ideally in mobile development
  • Experience with iOS, Android, React Native, Flutter, or Unity
  • Strong knowledge of Kotlin, Swift, JavaScript/TypeScript, C#, or Go
  • Experience building and maintaining CI/CD pipelines
  • Strong understanding of networking fundamentals and software architecture
  • Excellent communication skills and a pragmatic, product-focused mindset

Nice to have:

  • Experience developing SDKs or developer tools
  • Familiarity with AI-assisted development workflows
  • Experience supporting external developers and API integrations
  • Passion for building high-quality developer experiences
