We work closely with product, server engineering, design, marketing, and customer support teams to create new product experiences for our customers.

• Deep understanding of Android UI frameworks, including XML layouts and Jetpack Compose.
• Hands‑on knowledge of software engineering best practices across the full SDLC: coding standards, code reviews, Git workflows, CI/CD pipelines, automated testing, and mobile release operations.
• Familiarity with identity verification, authentication, and authorization protocols.
• Deep expertise in Android development, with a strong commitment to cross‑platform ownership and familiarity with other frontend platforms (e.g., iOS, web or Kotlin Multi‑Platform) to facilitate seamless feature parity and fungibility.
• Experience in AI‑integrated mobile development, including leveraging AI tools for spec‑driven development and prototyping.
• Strong ability to collaborate with Product Managers and Engineering Managers early in the development lifecycle to define technical specifications and build functional prototypes.
