募集要項

A fast-growing digital platform powering large-scale online communities is expanding its engineering team as it continues to scale its product and user experience. The business operates a subscription-based platform with a significant and growing user base, creating meaningful technical challenges around performance, engagement, and product evolution.

As an Android Engineer, you will take ownership of key features from concept through release, working closely with product managers and designers to turn ideas into high-quality mobile experiences. This role is focused on native Android development with Kotlin, where you will contribute to architecture decisions, improve technical quality through refactoring and code reviews, and help shape the future direction of the Android application.

What makes this role stand out is the level of ownership and influence. You will have the opportunity to drive technical modernization, explore new Android capabilities, contribute to architectural decisions, and apply AI-augmented development practices to increase productivity and product quality. Your work will directly impact a high-traffic consumer platform used by a large and engaged community.

If you have strong native Android experience, hands-on knowledge of Google Play Billing, and enjoy building products in collaboration with cross-functional teams, we’d love to hear from you.
