Waymo, Google’s former self-driving car project that’s now an independent business unit under Alphabet, is expanding its presence in the eastern U.S. The company said Thursday it would be opening offices in Pittsburgh, joining a growing suite of companies developing and testing autonomous vehicle technology in the Steel City.

The company will start by hiring around a dozen engineers, a source familiar with the move told TechCrunch, and they’ll co-locate in Google’s existing offices in the Bakery Square district. As of Thursday, only around three open positions for the Pittsburgh area were listed on Waymo’s website, but the company will be adding more roles soon.

Some of the new team will come from Pittsburgh-based RobotWits, a tech startup focused on autonomous vehicle decision-making. That includes RobotWits’ founder and CEO Maxim Likhachev, and other members of its engineering and technical team. While Waymo did not technically acquire the startup, it did acquire RobotWits’ IP rights, the source said.

There are no current plans to deploy the so-called Waymo Driver, its autonomous driving platform, in Pittsburgh, the source added. Instead, the new team will work on motion planning development, real-time route planning and developing Driver. Thus far, Driver has seen deployment in the Phoenix, Arizona metro area. Its Waymo Via trucking and cargo service will be deployed in a test run with trucking logistics company J.B. Hunt Transport Services in Texas.

AV tech rivals Aurora, Motional, Argo AI have already established offices in the city; combined with talent at Carnegie Melon University, the city has established itself as a bona fide hub for autonomous engineering development. Pittsburgh is also home to many smaller AV startups, including Locomation, which is working on autonomous trucks.

Waymo’s Pittsburgh location will join its network of offices in Mountain View, San Francisco, Phoenix, New York, Dallas, and Hyderabad, India.
