## About the Role

This engineer will support the development and testing of baseband hardware and PCBAs for advanced communications systems. The hardware in question is highly SWaP-C constrained and spans RF to digitization. The first 3–6 months of the role will be primarily in the lab testing and debugging existing hardware, after which the role transitions into more design work for follow-on hardware in different form factors and configurations. A strong background in both design and test is required., * Experience with part selection, schematic capture, layout, and test of complex mixed-signal boards targeting SoCs or FPGAs, including clocking, power, and high-speed interfaces

 * Experience working in desktop and embedded Linux
 * Experience with one or more scripting/embedded programming languages such as Python, C/C++, or Bash
 * Experience with lab equipment including high-speed oscilloscopes, bench power supplies, spectrum analyzers, and signal generators
 * Bachelor’s Degree in Electrical Engineering, Computer Engineering, or similar
 * Experience working on cross-disciplinary teams with mechanical and RF engineers, * Experience designing cost- and size-sensitive baseband hardware for commercial, cellular, or defense applications
 * Experience with high-reliability design for aerospace or defense applications
 * Experience designing for medium-rate production (up to thousands per year)
 * Understanding of RF communication systems and digital signal processing, and ability to translate these into hardware requirements for data converters, processing, and RF performance
 * Experience with NXP i.MX or similar processors
 * Experience with baseband processors
 * Experience with Xilinx/AMD FPGAs, MPSoCs, or ACAPs
 * Experience with ADI transceivers
 * Experience with Mentor Graphics Xpedition
 * Experience with Altium
 * Experience with SERDES (e.g., PCIe Gen 2+)
 * Experience with DDR (e.g., LPDDR5), Must Have
 * Bachelor’s Degree
 * 5+ years of hardware design (schematic capture, layout, routing, and bring-up)
 * 5+ years designing and evaluating complex electrical systems
 * 3+ years programming (e.g., Python, C/C++)
 * 1+ year experience with embedded Linux
 * 3+ years experience with test equipment (oscilloscopes, logic analyzers, emulators, digital multimeters)
 * 5+ years of experience with testing frameworks and debugging tools

Nice to Have

 * High-reliability design (aerospace/defense)
 * Communication hardware design experience
 * Experience with Xilinx/AMD FPGAs, MPSoCs, ACAPs
 * Experience with Mentor DxDesigner/Xpedition
 * Proficiency with Altium

## Description

* Test and debug of miniature hardware spanning RF front-end, transceivers, SoCs, and baseband processors
 * Design of communication hardware targeting miniature form factors
 * Writing and support of design validation and test plans
 * Collaboration with RF engineers, software engineers, mechanical engineers, and signal processing teams
