As a Power Integrity Engineer on the Facebook AR Product Team, you will work directly with the AR design team to influence design of high-speed interfaces and power systems in Facebook's AR prototypes and future line of consumer products. You will model, simulate, prototype, measure, and evaluate power integrity for design and development of functionally robust AR devices. You will become part of a team exploring new concepts through fast iterative prototyping. You will work cross-functionally with teams that will dynamically change depending on the problem and potentially include mechanical, firmware, software, electrical, and research experts. We want people who work well in teams, can take an ambiguous requirement, and can create elegant highly constrained solutions into high-volume consumer products. The ideal candidate would be comfortable specifying test equipment to evaluate the Power Integrity of systems. The candidate should be able to operate that same equipment with skill to determine root cause of noisy or marginal signaling or power delivery and be able to recommend design changes to create a margined and compliant system.
