Software Engineer - Perceptual Science

Come invent the future. At Facebook Reality Labs (FRL), software development is vital to turbocharging our scientific explorations and generating viable paths to the consumer products people will use for decades to come - products that will literally give people super powers. If you're a C/C++ expert with deep knowledge of real-time systems, a love for solving novel problems from first principles, and an aptitude for graphics or computer vision, you'll thrive in our collaborative environment. Join the world-class Applied Perception Science (APS) research team, whose work informs AR/VR systems by learning about the limits of human perceptual performance. APS conducts research to help define the requirements of future AR and VR devices. Partner with expert research scientists, mechanical engineers, electrical engineers, and other brilliant software minds to build cutting-edge prototypes, as we make science fiction real and change the world.
