Primary Responsibilities

• Design and develop power electronics circuits including switching regulators, 3-phase AC-to-DC converters, DC-DC converters, and power distribution architectures for missile and avionics systems.
• Design and develop safety-critical electronics including low-voltage firing sets, initiator safety circuits, power filtering, interlocks, and reliable stimulus sensing systems.
• Design CDU and safety circuits for LEEFI and NSI initiators. Create detailed schematics and PCB layouts using ECAD (Mentor Graphics DX Designer / Expedition or Altium Designer).
• Perform analog circuit design with emphasis on high-reliability, including filtering, protection, sensing, interfacing with A/D converters, and fail-safe architectures.
• Design for grounding, isolation, bonding, shielding, ESD, and EMI/EMC performance.
• Develop cable and harness designs with attention to grounding, shielding, isolation and signal integrity.
• Collaborate on co-design of power systems with embedded processors and FPGAs (Xilinx/AMD Zynq, MicroBlaze, and similar platforms).
• Support environmental qualification testing of avionics power hardware, including thermal cycling, shock and vibration, vacuum / pressure, salt fog and humidity, pyro-shock, resonant plate / beam testing, acceleration, and EMI/EMC testing.
• Design and implement board-level and system-level test setups for developed hardware and safety electronics.
• Perform hands‑on troubleshooting, debug, and validation using oscilloscopes, multimeters, function generators, and related lab equipment.
• Work effectively in a fast-paced, multidisciplinary development environment with evolving priorities and tight schedules.
