We are looking for a highly skilled and experienced Senior EMI/EMC (Electromagnetic Interference/Electromagnetic Compatibility) Engineer I to join our engineering team in the aerospace and defense industry. The ideal candidate will play a critical role in ensuring that our phased array communication systems meet all EMI/EMC requirements and standards. You will work closely with cross-functional teams, including design, test, and systems engineering, to develop, analyze, and implement EMI/EMC control strategies that ensure the integrity and performance of our products in harsh environments.
JOB DUTIES AND RESPONSIBILITIES
- Develop and implement EMI/EMC control plans, including analysis of designs to identify potential interference issues and suggest mitigations.
- Provide technical guidance to design teams on EMI/EMC considerations, ensuring that all systems comply with relevant standards and performance requirements.
- Plan, coordinate, and conduct EMI/EMC testing for electronics modules and phased array communication systems, including preparing test plans, defining test setups, and performing tests in accordance with relevant standards (e.g., MIL-STD-461, DO-160, ECSS).
- Utilize simulation tools (e.g., CST Studio Suite, ANSYS HFSS) to model electromagnetic fields and predict potential interference issues at the component, subsystem, and system levels.
- Ensure that all products meet regulatory requirements and industry standards for EMI/EMC, including documentation, certification, and reporting to stakeholders.
- Investigate and resolve EMI/EMC-related issues, including conducting root cause analysis and developing corrective actions to address non-compliance or performance shortfalls.
- Prepare comprehensive reports and technical documentation, including test results, compliance matrices, and design guidelines for internal and external stakeholders.
- Lead initiatives to improve EMI/EMC design practices, testing methodologies, and tools to enhance overall product quality and performance.
- Mentor and train junior engineers, providing guidance on best practices in EMI/EMC design and testing.
JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS
- Bachelor’s or Master’s degree in Electrical Engineering, Physics, or a related field.
- Minimum of 4 years of experience in EMI/EMC engineering, preferably within the aerospace and defense industry.
- Deep understanding of EMI/EMC principles, standards, and regulations (e.g., MIL-STD-461, DO-160, ECSS).
- Experience with EMI/EMC test equipment and tools (e.g., spectrum analyzers, signal generators, antennas).
- Proficiency in electromagnetic simulation software (e.g., CST Studio Suite, ANSYS HFSS, FEKO).
- Knowledge of circuit and system-level design for EMI/EMC mitigation, including shielding, filtering, and grounding techniques.
- Strong analytical, problem-solving, and troubleshooting skills.
- Excellent communication and presentation skills, with the ability to explain complex technical concepts to diverse audiences.
- Ability to work independently and collaboratively in a fast-paced, multidisciplinary environment.
PREFERRED EXPERIENCE
- Experience with EMI/EMC compliance for communication systems, particularly phased arrays.
- Strong experience in EMI/EMC test planning and execution.
- Certification in EMI/EMC (e.g. Certified EMC Engineer).
- Familiarity with systems engineering practices and tools (e.g. Jama, DOORS).
