Sunnyvale, CA

Job Description

As a Signal Integrity power Integrity Design Engineer on Meta’s RL Product Team, you will work directly with the RL design team to influence the design of Meta's RL products and prototypes. You will work on system level signal integrity and Power Integrity design and validation. Work scope includes SI/PI simulation, automation development, bring-up, validation and test in the lab for simulation correlation to improve EMC design quality for all design phases. The individual filling this position is expected to perform independently on multiple projects, work within teams interfacing with other engineers and technicians, and collaborate well with different XFN team engineers and/or outside vendors to complete all necessary tasks. We want people who can take an ambiguous requirement and can create highly constrained solutions into high-volume consumer products. The ideal candidate has a strong SI/PI design background, excellent simulation and lab measurement capability, experience in designing and manufacturing consumer technology products and a great team player can work with XFNs with great communication skills.
