Requirements:

  • Bachelors degree in Electrical Engineering or Computer Engineering.
  • Advanced training or graduate study in electronics, signal integrity, power electronics, embedded systems, controls, or avionics is preferred.
  • At least 5 years of progressive electrical engineering experience designing, analyzing, integrating, and testing electronic hardware, preferably in aerospace, defense, or other high-reliability environments.
  • At least 4 years of hands-on schematic development and circuit analysis covering analog, digital, mixed-signal, power, interface, protection, and embedded electronic designs.
  • At least 4 years of experience using PSpice, SPICE, or equivalent tools to model and analyze circuits, electrical signals, loads, power distribution, transients, tolerances, and system or interface behavior.
  • At least 4 years of avionics or aerospace electronics experience involving aircraft electrical interfaces, embedded hardware, laboratory integration, troubleshooting, verification, or qualification.
  • A valid, clear drivers license is required.

Responsibilities:

  • Design, analyze, and integrate avionics electronic hardware, circuit card assemblies, and electrical interfaces for high-reliability aerospace and defense systems.
  • Develop schematics and conduct circuit, signal, power distribution, loading, transient, and interface analyses using PSpice or equivalent modeling and simulation tools.
  • Build electrical models to predict circuit and interface behavior across operating conditions, component tolerances, loads, power states, and system-level electrical environments.
  • Lead hardware troubleshooting, design verification, laboratory integration, and root-cause analysis for analog, digital, mixed-signal, power, and embedded avionics electronics.
  • Advance avionics hardware through requirements development, analysis, design, prototyping, integration, qualification, and technical data delivery in collaboration with multidisciplinary engineering teams.
  • Develop and review schematics, component selections, interface circuits, grounding approaches, power architectures, and electrical design documentation.
  • Perform simulations and develop circuit, signal integrity, power distribution, loading, transient, tolerance, and worst-case electrical models and analyses.
  • Analyze aircraft and subsystem electrical interfaces, including voltage and current margins, grounding, impedance, noise, transients, power quality, distribution, and signal behavior.
  • Support prototype bring-up, bench testing, HIL/SIL integration, troubleshooting, failure analysis, and verification of circuit card assemblies and avionics electronic subsystems.
  • Collaborate with systems, software, firmware, mechanical, test, manufacturing, and qualification engineers to resolve integration issues and ensure hardware meets performance requirements.
