• Candidate must have expertise in digital PCB design and troubleshooting including embedded processor, microcontroller, or FPGA-based designs.
• Candidate must have proven experience in design, test, troubleshooting, and manufacture of complex multi-layer electronic circuit card assemblies.
• Candidate must have hands-on laboratory experience with instrumentation, test equipment, and debug/test methods.
• Candidate must have experience with technical problem solving and root cause analysis.
• Candidate must demonstrate an ability to decompose system-level considerations (i.e. requirements) to lower design levels.
• Candidate must have the ability to interpret schematics, wiring diagrams, and system block diagrams.
• Candidate must have demonstrated experience effectively communicating within a team environment.
• Candidate must be a resident of the North Alabama area or willing to relocate to the Huntsville - North Alabama, AL area.

Preferred Qualifications.
• Preference shown to candidates who possess a Master's Degree in Electrical Engineering, Computer Engineering, or equivalent degree from an ABET-accredited university
• Preference shown to candidates who have experience and/or working knowledge of:
• Experience with military/aerospace environmental testing and qualification, autonomous flight safety systems, or similar applications.
• Experience designing low-voltage firing sets, initiator safety electronics, and reliable stimulus sensing circuits.
• Familiarity with FPGA/SoC platforms (Xilinx/AMD Zynq family, MicroBlaze, etc.).
• Python and/or C programming for test automation, scripting, or board bring-up and debug.
• Hands-on soldering, board-level rework, and hardware debug skills.
• Cable and harness design experience.
• Experience designing automated or semi-automated test systems for safety electronics boards.
• Prior work on missile, munitions, or high-reliability avionics power systems.
• Multiple high-speed serial communication standards and memory interfaces (e.g. GigE, 10 GigE, Aurora, DDR2, DDR3, DDR4, JESD204B, PCIe, SATA).
• High-speed design analysis tools such as HyperLynx.
• Rigid-flex, microvia, blind via, and buried via printed circuit board design.
