Job Description:

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.

Job Responsibility:

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

Requirements:

Bachelor’s Degree in Electrical Engineering, Computer Engineering, or similar
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
Experience working on cross-disciplinary teams with mechanical and RF engineers
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
Ability to obtain an Interim Secret clearance is sufficient to start

Nice to have:

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