Electrical Engineer 3 - Mixed Signal and PCB

Electrical Engineer 3 - Mixed Signal & PCB

Location: Illinois (On-site)

We're partnering with a leading engineering, manufacturing, and technology company looking for an experienced Electrical Engineer III. In this role, you'll design and develop high-reliability mixed-signal electronic hardware for advanced electromechanical actuation systems, working across schematic design, PCB development, hardware verification, and product validation in a collaborative engineering environment.

• Design analog, digital, and mixed-signal circuits and multilayer PCBs.
• Develop schematics, PCB layouts, and engineering documentation.
• Perform signal integrity, EMC, thermal, and reliability analysis.
• Support hardware verification, validation, HIL testing, and troubleshooting.
• Collaborate with mechanical, systems, and software engineering teams.
• Participate in design reviews, FMEAs, and support compliance with industry standards.

• Bachelors degree in Electrical Engineering or a related discipline.
• 5+ years' experience in electrical design for aerospace, defence, or other high-reliability electromechanical systems.
• Strong proficiency with Altium Designer or similar PCB design software.
• Experience designing complex multilayer mixed-signal PCBs.
• Strong knowledge of analog and digital circuit design, including microcontrollers, FPGAs, ADC/DAC interfaces, and communication protocols (CAN, RS-485, ARINC-429).
• Understanding of EMC mitigation techniques and aerospace hardware development standards (DO-160, DO-254).
• Excellent troubleshooting skills using laboratory test equipment.
• Strong communication skills and the ability to work within cross-functional engineering teams.

• Experience with safety-critical actuation systems or flight-control hardware.
• Familiarity with reliability engineering, embedded firmware, or FPGA development.
• Experience with MATLAB/Simulink, NI LabVIEW, or electronic simulation tools.
