Android Engineer

About the role

We're hiring Android Engineers across multiple teams at Whatnot, with opportunities to work on product experiences or mobile infrastructure. On our product teams, you'll build mobile experiences that sit close to our buyers and sellers, shaping how people discover Whatnot, buy and sell, and engage with our marketplace. You'll partner closely with product, design, and backend engineering to solve customer problems and build intuitive, high-quality experiences at scale.

We're also hiring on our App Platform team, where you'll build the mobile infrastructure that powers every Android experience across the app. From developer tooling and app architecture to performance, reliability, and platform foundations, you'll create systems that enable product teams to ship faster while delivering a best-in-class experience to millions of users.

Rather than applying to a specific team, you'll go through a general interview process focused on your technical skills and experience. Throughout the process, we'll learn more about your interests and match you with the team where you'll have the greatest impact.

Responsibilities

• Develop high-quality Android features and systems using Kotlin and Jetpack Compose.

• Build with performance, reliability, scalability, and user experience in mind.
• Uphold engineering excellence through code reviews, documentation, and thoughtful technical discussions that raise the bar across the team.

Qualifications

• 4+ years of experience building and shipping high-quality Android applications.
• Bachelor's degree in Computer Science, a related field, or equivalent work experience.

• Adept at reactive programming with Kotlin Coroutines and Flows.
• Fluent in MVI or MVVM development.
• Care deeply about product quality and performance, creating polished experiences that balance usability and trust.
• Thrive in cross-functional environments, partnering effectively with product, design, and backend peers.
• Are comfortable using data and experimentation (SQL, Snowflake, A/B testing) to guide decisions.
• Communicate clearly and drive alignment across teams in ambiguous, fast-changing environments.
• Have a growth mindset, taking ownership from concept to launch while mentoring others along the way.
