Yahoo Mail is the ultimate consumer inbox with hundreds of millions of users. It's the best way to access your email and stay organized from a computer, phone or tablet. With its beautiful design and lightning fast speed, Yahoo Mail makes reading, organizing, and sending emails easier than ever.

Yahoo Mail has an exciting opportunity for a Principal/Staff Mobile Engineer to lead our Mobile platform strategy and explore React Native. As a staff mobile engineer, you will evolve the mobile culture and help build our apps in a scalable fashion. You'll play a key role in our technology decisions and implementation, and you'll see firsthand the impact that we're making.

This is a foundational engineering role: you'll own tech stack, architecture, performance, and product experience end-to-end.

You'll collaborate directly with design, backend, and product to shape how Mail works.
