Key Responsibilities

• Perform DMSMS assessments and identify risks associated with obsolete or soon-to-be-obsolete electronic components.
• Develop mitigation strategies, including alternate component selection, technology refresh, FPGA redesign, and Last Time Buy recommendations.
• Design FPGA-based replacements for obsolete ASICs, CPLDs, PLDs, and discrete logic.
• Develop and maintain qualified replacement Bills of Material.
• Support schematic updates, PCB design reviews, signal integrity, power integrity, and hardware verification activities.
• Evaluate design and interface impacts related to DO-254, DO-160, ARP4754A, and ARP4761.
• Support laboratory testing, hardware integration, troubleshooting, and configuration management.
• Develop certification-quality engineering documentation.
• Support engineering change implementation and communicate technical recommendations to customers and internal stakeholders.
• Assist with ASIC-related design activities when required.

Qualifications

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Aerospace Engineering, Systems Engineering, Computer Science, or a related technical discipline.
• 10+ years of professional experience with FPGA or embedded hardware development.
• FPGA development experience using at least one of the following: AMD/Xilinx Vivado, Intel Quartus, or Microchip Libero.
• Experience programming in VHDL, Verilog, and/or SystemVerilog.
• Experience with DO-254 and DO-160 requirements or certification activities.
• Knowledge of digital electronics, PCB design reviews, signal integrity, power integrity, and EMI/EMC considerations.
• Experience with one or more avionics or embedded communication interfaces, such as: ARINC 429, MIL-STD-1553, Ethernet, PCIe, SPI, I²C, CAN, or UART.

Preferred Skills

• Master’s degree in Engineering, Systems Engineering, or a related discipline.
• Experience performing DMSMS or electronic component obsolescence analysis.
• Experience developing replacement Bills of Material and evaluating alternate components.
• Experience supporting FPGA technology refresh or ASIC-to-FPGA redesign efforts.
• Familiarity with ARP4754A and ARP4761.
• Experience with FACE architecture or standards.
• Experience working within commercial or military avionics development environments.
• Background supporting flight displays, mission computers, navigation systems, flight controls, radar, engine controls, UAV/UAS platforms, or space electronics.

Benefits

• Competitive pay, comprehensive medical/dental/life and disability coverage.
• 401(k) with employer match.
• Professional development support.
• A flexible, friendly workplace.
