Software Development Engineer II (Flutter), Maps SDK
Mapbox is the leading real-time location platform for a new generation of location-aware businesses. Mapbox is the only platform that equips organizations with the full set of tools to power the navigation of people, packages, and vehicles everywhere. More than 4 million registered developers have chosen Mapbox because of the platform’s flexibility, security and privacy compliance. Organizations use Mapbox applications, data, SDKs and APIs to create customized and immersive experiences that delight their customers.
The Maps SDK team builds the public library that powers our mobile maps. Customers of our SDK include apps on Flutter, Android and iOS, small and large. We work with devices of all shapes and forms, from the latest flagship phone to tablets, laptops, smartwatches, HMD, and embedded boards. Our developers build apps, games and navigation experiences that top the App Store and Play Store rankings, and we are constantly working together to help them build what’s next, whether that’s an Augmented Reality game, a popular consumer app, or an autonomous driving experience.
As AI becomes embedded in modern engineering workflows, we value engineers who can thoughtfully integrate AI into design, development, and decision-making. Our interview process will include discussion of how you use AI in your engineering workflow.
