Why Box needs you?
We're looking for a Staff Engineer to join our Mobile team in Warsaw and lead a strategic platform transformation. Our mission is to deliver a world-class mobile experience that keeps pace with our web product — and to do that, we're moving to React Native as our cross-platform foundation.
You will be the technical anchor of this multi-year initiative: setting the architectural direction, driving the adoption of React Native across the team, and enabling us to ship the same features on iOS, Android, and web from a single codebase. Mobile is a high-visibility surface used by millions of Box customers, and this role sits at the heart of how we evolve it.
This is not a solo contributor role. We have firepower in the team. What we need is someone who can coach engineers, build engineering culture, and make the transformation stick — not just close the gap once, but establish a sustainable, scalable way of building cross-platform products at Box.
