About The Position

Snap Inc. is a technology company focused on improving communication through its camera. The Specs Inc. subsidiary develops advanced eyewear and AR experiences. We are seeking an Electrical Signal Integrity Engineer to join the Specs team. This role involves performing detailed simulations for high-speed signal integrity and power system integrity to ensure the quality performance of Spectacles subsystems. The engineer will simulate and define AC/DC power distribution networks and impedance masks, design complex ICs (SOCs, PMICs, Wireless ICs, sensors) for low-power consumer electronics, and lead/contribute to technical design reviews. Responsibilities also include supervising and reviewing PCB, Flex, and Rigid Flex designs for SI, PI, EMC, EMI, debugging hardware issues with cross-functional teams, analyzing circuit parasitics and tolerances, and testing/validating electrical designs. The role requires close collaboration with mechanical, software, RF, thermal, and industrial design teams, authoring electrical test documentation, and developing electronic prototypes. Support will also be provided during development builds at external contract manufacturers.

Requirements

Strong electrical engineering fundamentals and understanding of best practices.
Experience in electronic design, including component selection, schematic design, and familiarity with schematic capture and layout tools such as Cadence Allegro and OrCAD Capture.
Experience working with various communication interfaces such as USB, I2C/I3C, SPI, UART, MIPI, SWD and PCIE.
Knowledge of layout strategies and tradeoffs for linear and switching power supply circuits, EMI mitigation, high-speed signal integrity and power delivery networks.
Experience with lab equipment such as oscilloscopes, battery simulators, logic analyzers and thermal chambers.
Great interpersonal skills; ability to collaborate across groups through written, verbal and visual formats.
BS/BA degree in Electrical Engineering, Computer Science or related field or equivalent years of experience.
3+ years of experience in electrical or hardware engineering.
Ability to travel internationally 10% of the time.

Nice To Haves

MS or PhD in Electrical Engineering or related field or equivalent years of experience.
Experience defining integrated circuit design power delivery specifications such as impedance masks and DCR targets.
Experience working cross functionally to resolve problematic signal integrity issues including with mechanical, electrical, and firmware teams.
Great interpersonal skills; ability to collaborate across groups.
Excellent process development and documentation skills.
A passion for Snapchat and creativity!
