Tesla Inc. (TSLA)  is turning to a new kind of engineer to lead its user interface operations. 

Scott Simms is the electric automaker's newest user interface engineering director, according to his LinkedIn Corp. (LNKD) profile. Simms had long been a leader at Microsoft Corp.'s (MSFT) video game engineering unit.

Simms joined Tesla sometime within the last month as "Director of UI Engineering," according to his profile. In his old post at Microsoft, Simms was Principal Software Development Manager and worked on popular titles including the Halo franchise and Microsoft Kinect Sports games.

Simms described on his LinkedIn that he had a part in Microsoft's "AR & 3D reconstruction on mobile devices. Managed computer vision, UI and app teams developing monocular SLAM and 3D reconstruction running real time on resource constrained hardware."

His Tesla post on LinkedIn doesn't yet have a job description, but Tesla is largely expected to implement some advanced applications on resource-constrained hardware similar to Microsoft.

Tesla stock slipped 1.9% to $298.70 in midday trading Thursday. Microsoft shares fell 1.6% to $83.25.
