Mapbox provides the building blocks that enable our customers to push the boundaries of what’s possible with interactive maps and how people use location technologies in their daily lives. Whether you’re watching the delivery of your grocery order on Instacart, looking at a gym on ClassPass, sending your snaps on Snapchat, tracking your personal best on Strava, monitoring your gas budget on Metromile, or checking today’s forecast on The Weather Channel, Mapbox is the location and maps within those apps. We’re changing how people move by live-mapping the world. We are the developer platform for location.

What We Do

The Core SDK team provides the foundational component that powers Mapbox’s Search, Navigation, and Maps teams SDK products. The work we do makes a big impact in the lives of millions of our customers and their end-users worldwide. Our scope is broad and ranges from maintaining a middleware component providing foundational functionality to our core engines and mobile SDKs, a client-side implementation of our telemetry platform, and a platform bindings generator that exposes our business logic APIs to mobile platforms like Android, iOS, and others.

  • Work with a modern code base, using the best practices of software engineering and tools. You'll also work on establishing platform bindings to all modern mobile platform languages
  • Collaborate with internal teams to ensure best practices for cross-platform API design
  • Seek alignment by proposing new ideas and taking the lead role when necessary
  • Improve the project’s performance, stability, maintainability, and simplicity
  • Design and implement high-priority features
  • Craft expressive and easy to use APIs for developers using our SDKs
  • Dive deep into the underlying cross-platform implementations that power our frameworks

  • Familiarity with iOS native technologies such as Objective-C and Swift. 
  • Experience with APIs and knowledge on how cross-platform code is integrated.
  • Strong communication skills and ability to collaborate effectively with distributed teams.
  • Desire to build frameworks and developer tools.

Helpful experiences that are a plus but not a requirement

What We Value

In addition to our core values, which are not unique to this position and are necessary for Mapbox leaders:

  • We value high performing creative individuals who dig into problems and opportunities.
  • We believe in individuals being their whole selves at work. We commit to this through supportive health care, parental leave, flexibility for the things that come up in life, and innovating on how we think about supporting our people
  • We emphasize an environment of teaching and learning to equip employees with the tools needed to be successful in their function and the company
  • We strongly believe in the value of growing a diverse team and encourage people of all backgrounds, genders, ethnicities, abilities, and sexual orientations to apply
