Job Description: The Senior Analog Electronics Engineer works alongside the Senior Digital Electronics Engineer to complete system-level and board-level hardware design for cameras and digital image/video processing and storage systems on interplanetary orbiters, landers, and rovers and earth-orbiting space systems. The cameras will use a variety of sensors, including CCDs, CMOS active-pixel sensors, and microbolometer arrays for imaging in the visible spectrum and beyond. The electronics design team also includes the Lead Designer/Systems Engineer, Mechanical/Thermal Engineer, Software Engineer, and PCB Layout Designer. Required Skills: • Architect signal chains for buffering and digital conversion of high-dynamic range, low noise, video outputs from analog image sensors. • Implement and analyze/optimize linear and switching power supplies for your own analog circuits and to meet the requirements of digital circuits; Validate control loop stability and other power integrity parameters. • Design analog clock drivers and motor driver circuits. • Design power distribution networks for digital designs to minimize ground bounce. • Evaluate and select radiation-tolerant components. • Use schematic capture tools (Altium Designer) to capture designs. • Simulate analog circuits using PSpice (or equivalent) tools. • Produce power estimates for all analog loads in the system and characterize power converter efficiency; integrate power estimates from the Digital Electronics Engineer and work with the Thermal Engineer to mitigate thermal concerns. • Perform worst-case analysis for all analog and power circuits. • Perform electronic parts stress analysis to validate derating margins across entire design. • Specify and direct EMI/EMC testing in-house and at third-party vendor sites. • Design cable harnessing to support thermal and thermal-vacuum tests. • Work alongside PCB Layout Designer to specify PCB stack-ups and provide feedback on component placement and routing. • Evaluate susceptibility of design to cumulative and single-event radiation effects and develop mitigation where needed. • Write reports and presentations for design, validation, and analyses. • Present and defend all aspects of design and analysis at internal peer reviews, and customer reviews.
