If you are looking for hands-on, interactive, and autonomous work, Cesium Astro is the place for you. We are actively seeking passionate, collaborative, energetic, and forward-thinking individuals to join our team.

We are looking for a highly skilled and experienced Principal EMI/EMC (Electromagnetic Interference/Electromagnetic Compatibility) Engineer II to join our engineering team in the space industry. The ideal candidate will play a critical role in ensuring that our space systems, including spacecraft, satellites, and ground support equipment, 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 the harsh environments of space.

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 space 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, Electromagnetics, Physics, or a related field.
• Minimum of 11 years of experience in EMI/EMC engineering, preferably within the space, aerospace, or defense industries.
• 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 spacecraft systems, satellites, or launch vehicles.
• Certification in EMI/EMC (e.g., Certified EMC Engineer).
• Familiarity with systems engineering practices and tools (e.g., DOORS, SysML).
