We have spent time with Mapbox APIs ourselves and been genuinely impressed: the developer experience is smooth, the docs are clear, the tooling is flexible, and the product just works. That is not something you can say about every platform, and it matters when you are deciding where to work. Here, you will be building something that other developers actually enjoy using. Mapbox has pulled in more than $500 million from investors, is valued at over $1 billion, and counts 4 million+ developers and nearly 40% of the Fortune 500 among its users. Glassdoor reviews tend to repeat the same themes: smart, friendly colleagues, interesting technical challenges, competitive pay, and a remote-first culture with real work-life balance. There are offices in the US, Finland, Germany, the UK, and Japan, but most roles can be done remotely. Still, the Glassdoor rating is 3.6, so opinions are mixed. There is also some frustration around leadership style, shifting priorities, and a performance review process that can feel a bit rigid. However, if you are looking to work on technology with a global dependency and want to be proud of what you ship, Mapbox could be a great fit.

• Work fully remotely from the UK. • Work on navigation services used by millions of people across consumer, automotive, and logistics. • Access supportive healthcare, parental leave, and flexibility for life events. • Join a team that emphasises teaching, learning, and mentorship. • Work at the intersection of distributed systems, geospatial technology, and real-time traffic data.

Mapbox is the leading real-time location platform for a new generation of location-aware businesses, with over 4 million registered developers. The Navigation Traffic team develops and maintains the web services powering virtually all of Mapbox's strategic navigation initiatives — spanning distributed systems on AWS, geospatial localisation, traffic telemetry, and mapping — across consumer, automotive, and logistics use cases.
