Raytheon Vision Systems is seeking a talented Senior Principal Mixed Signal Design Engineer to join our design team.  

This position will be onsite in Goleta, CA.

What You Will Do

• Collaborate in a fast-paced multidisciplinary team environment to develop cutting-edge image sensor products.
• Participate in mixed-signal ASIC/ROIC development activities with cross-functional teams including chip architecture, specification, design, verification, validation, fabrication, packaging, debugging, test development, failure analysis, and documentation.
• Design, develop, and characterization of Readout Integrated Circuits (ROICs) for advanced sensing systems.
• Evaluate various aspects of the process flow from design to synthesis, place and route, timing and power use. As well as determine architecture design, logic design, and system simulation and define module interfaces for simulation.
• Design mixed-signal integrated circuits for image sensors, including analog signal chain, digital timing and image processing, and low-power 12 – 14 bit on-chip analog to digital converters.
• Guide and coordinate teams of highly skilled engineers in complex, multidisciplinary technical environments. As well as communicate complex technical concepts and program status through briefings and technical reviews with senior government and customer stakeholders, including flag officer–level leadership.
