Android Engineer, Seller Growth at whatnot

This role is ideal for a Senior Android Engineer with at least 5 years of experience who thrives at the intersection of product growth and platform stability. You should be an expert in the modern Android stack—specifically **Kotlin and Jetpack Compose**—with a background in building high-quality, responsive UIs. Experience with reactive programming and MVI/MVVM architectures is essential for this fast-paced, experimentation-heavy environment. The compensation is highly competitive ($195k–$290k) and comes with a robust benefits package, including a 4% 401k match, child care allowances, and "dogfooding" credits to spend on the app. While the company values in-person collaboration in their **SF, NY, LA, or Seattle** hubs, they offer a flexible "remote co-located" model that balances home and office time. **You might be a good fit if you...** * Enjoy working on "Seller Growth"—building onboarding funnels, identity verification (IDV), and fraud prevention systems. * Are data-driven and comfortable using SQL or Snowflake to measure the success of your A/B tests. * Want to move beyond just UI to influence backend pipelines and predictive models. * Value a high-growth environment where you can mentor others and ship features that impact thousands of new users weekly.
