Facebook Reality Labs is building products that make it easier for people to connect with the ones they love most. We are a team of world-class experts developing and shipping products at the intersection of hardware, software, content, and health. Our team has the responsibility for taking breakthrough concepts and delivering them to market at scale. We are seeking an SI/PI Engineer who has experience in SiP development, consumer electronics, and battery operated mobile products.

As a SIPI (Signal Integrity and Power Integrity) Engineer at Facebook, you will take a critical role in developing next generation Consumer Hardware Systems. You will be part of the EE design team, and responsible for building SIPI simulation process for boards/FPCs/SiPs, validating results in the lab for correlation to improve SIPI design quality. The person in this role is expected to work independently and lead projects, as well as work within teams interfacing with other engineers, technicians and/or outside vendors to complete all necessary SI/PI tasks. In particular, the role entails close collaboration with EE designers, system validation engineers, and vendors to help establish/validate system requirements and hardware specifications. We want people who work well in teams, can brainstorm big ideas, work in new technology areas, are able to drive a concept into a prototype, and can envision how a prototype could transition into a high-volume consumer product. Our ideal candidate has a strong SIPI design background, excellent simulation and lab measurement capability, and experience in designing and manufacturing space constrained consumer technology products.
