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.\nJOB DUTIES AND RESPONSIBILITIES\nDevelop and implement EMI/EMC control plans, including analysis of designs to identify potential interference issues and suggest mitigations.\nProvide technical guidance to design teams on EMI/EMC considerations, ensuring that all systems comply with relevant standards and performance requirements.\nPlan, 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).\nUtilize 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.\nEnsure that all products meet regulatory requirements and industry standards for EMI/EMC, including documentation, certification, and reporting to stakeholders.\nInvestigate and resolve EMI/EMC-related issues, including conducting root cause analysis and developing corrective actions to address non-compliance or performance shortfalls.\nPrepare comprehensive reports and technical documentation, including test results, compliance matrices, and design guidelines for internal and external stakeholders.\nLead initiatives to improve EMI/EMC design practices, testing methodologies, and tools to enhance overall product quality and performance.\nMentor and train junior engineers, providing guidance on best practices in EMI/EMC design and testing.\nJOB REQUIREMENTS AND MINIMUM QUALIFICATIONS\nBachelor’s or Master’s degree in Electrical Engineering, Physics, or a related field.\nMinimum of 5 years of experience in EMI/EMC engineering, preferably within the aerospace and defense industry.\nDeep understanding of EMI/EMC principles, standards, and regulations (e.g., MIL-STD-461, DO-160, ECSS).\nExperience with EMI/EMC test equipment and tools (e.g., spectrum analyzers, signal generators, antennas).\nProficiency in electromagnetic simulation software (e.g., CST Studio Suite, ANSYS HFSS, FEKO).\nKnowledge of circuit and system-level design for EMI/EMC mitigation, including shielding, filtering, and grounding techniques.\nStrong analytical, problem-solving, and troubleshooting skills.\nExcellent communication and presentation skills, with the ability to explain complex technical concepts to diverse audiences.\nAbility to work independently and collaboratively in a fast-paced, multidisciplinary environment.\nPREFERRED EXPERIENCE\nExperience with EMI/EMC compliance for communication systems, particularly phased arrays.\nStrong experience in EMI/EMC test planning and execution.\nCertification in EMI/EMC (e.g. Certified EMC Engineer).\nFamiliarity with systems engineering practices and tools (e.g. Jama, DOORS).","description_format":"text","description_chars":3377,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Embedded
