The data we gather, organize, and share enables some of what we think is the most compelling map infra. It is built from real-time events happening globally, historical structured data, and even some things that require creativity to get into usable form (tway IDs?) To us, data eng is about infrastructure, and infrastructure is about reliability. A lot of this role is gathering data, but most importantly being able to organize it and make it simple and something you can easily use to assmble into a form where the data science team can make impact.
