comma.ai is bringing ghostriding to the masses. We have over 7,000,000 miles of 20+ FPS video from thousands of users driving with our dashcam app, chffr, and more than one thousand developers around the globe driving with our open source driving agent, openpilot.
openpilot currently supports more than 5 million cars in US alone, including more than 50 different makes, models and model years. We also sell EON Dashcam DevKit, which integrates with the comma ecosystem and can run openpilot.
We're looking for motivated and intelligent engineers to join our team in our San Francisco office. Bonus if you've done well at math competitions (USAMO, IMO, PUTNAM) and competition programming (IOI, ACM, USACO, Code Jam, Topcoder). We offer competitive salaries and typical startup perks, including a gym membership, chef-cooked meals and unlimited snacks.
We're always open to hiring software engineers. Know things a computer engineering graduate would know and send one of the solutions with your application to either programming challenge below. Good luck!
Below are trips from our dash cam users in the SF Bay Area, each of which is a JSON file containing an array of coordinates and speed (m/s) sampled at once per second. Build a performant web app containing an interactive map visualizing the distribution of speeds among these trips. All trips should be simultaneously visible on the map.
