Opto-Mechanical Engineer

As an Opto-Mechanical Engineer for the Facebook Reality Labs(FRL) Eye Tracking team, you will advance the state of human tracking technologies by designing and implementing opto-mechanical systems in a broad range of eye tracking research applications. Working closely with a team of tracking experts, you will manage the integration of complex opto-mechanical system into forms with a wide variety constraints and requirements. You will identify new strategies for integration that enhance the performance of eye tracking systems. You will help build new eye tracking and gaze estimation methods by designing, integrating, building, and testing opto-mechanical systems.
