Castelion Corporation•Torrance, CA
•Onsite
About The Position
We are hiring an EMI/EMC Engineer to own electromagnetic compatibility across our avionics hardware stack. This role is responsible for ensuring that avionics electronics, including flight computers, sensors, communications systems, and power electronics, operate reliably without causing or suffering from electromagnetic interference.
Requirements
- Bachelor's degree in Electrical Engineering or related field
- Hands-on experience with EMI/EMC testing, troubleshooting, or mitigation in electronic hardware systems
- Strong understanding of grounding, shielding, filtering, and electromagnetic coupling mechanisms
- Experience using lab instrumentation such as spectrum analyzers, oscilloscopes, signal generators, and current probes
- Ability to diagnose hardware interference issues and translate findings into practical design improvements
- Experience working closely with electrical hardware or PCB design teams
- Strong troubleshooting and problem-solving skills in lab environments
- Ability to work cross-functionally with hardware, test, and manufacturing teams
Nice To Haves
- Experience supporting EMI/EMC compliance testing such as MIL-STD-461 or DO-160
- Familiarity with avionics, RF systems, or high-speed digital electronics
- Experience working with cable harnessing, connectors, and shielding strategies in aerospace systems
- Experience debugging EMI issues at board, subsystem, or platform level
- Experience collaborating with external EMI compliance laboratories
- Familiarity with PCB design tools such as Altium or similar ECAD tools
- Experience with electromagnetic modeling or simulation tools
Responsibilities
- Integrate EMI/EMC considerations early into avionics hardware design, working closely with PCB designers and hardware engineers
- Review schematics and PCB layouts to ensure proper grounding, filtering, shielding, and return path integrity
- Develop mitigation strategies including filtering, cable shielding, bonding, and enclosure design
- Support system-level EMI risk analysis and identify potential interference sources across avionics subsystems
- Plan and execute EMI/EMC validation testing including radiated and conducted emissions and susceptibility testing
- Troubleshoot electromagnetic interference issues at the board, cable harness, and system levels
- Analyze test data to identify root causes of EMI issues and drive corrective design actions
- Collaborate with avionics test engineers to build and refine test setups for EMI validation
- Develop internal design guidelines and best practices to reduce EMI risk in future hardware iterations
- Document test results, mitigation strategies, and engineering recommendations
Benefits
- Comprehensive medical, vision, and dental insurance
- Four weeks of paid time off per year
- Long-term stock incentives
