What is an EMI EMC engineer?

EMI/EMC engineers are professionals who specialize in addressing electromagnetic interference (EMI) and ensuring electromagnetic compatibility (EMC) in electronic devices and systems. They work to design, test, and troubleshoot products so that they do not emit excessive electromagnetic noise and are not susceptible to interference from other sources. Their role is critical in industries such as automotive, aerospace, telecommunications, and consumer electronics, where meeting regulatory standards for EMI and EMC is essential for safety and product reliability.

What skills and qualifications are needed to thrive as an EMI EMC engineer?

To thrive as an EMI/EMC Engineer, you need a solid background in electrical engineering, understanding of electromagnetic theory, circuit design, and relevant industry standards, typically supported by a bachelor’s degree in engineering or a related field. Familiarity with EMI/EMC testing equipment, simulation tools such as CST or HFSS, and certifications like iNARTE EMC Engineer can be highly advantageous. Strong analytical thinking, attention to detail, and effective communication skills set top professionals apart in this role. These skills are crucial for ensuring products meet regulatory requirements, function reliably, and prevent costly compliance issues.

What are common challenges faced by EMI EMC engineers during product development, and how can they be addressed?

EMI/EMC Engineers often encounter challenges such as identifying and mitigating sources of electromagnetic interference early in the design process. These issues may arise from circuit layout, component selection, or enclosure design. To address these challenges, engineers collaborate closely with design and hardware teams, conduct pre-compliance testing, and implement shielding, filtering, and grounding strategies. Staying updated with changing regulatory standards and maintaining thorough documentation are also crucial for successful compliance.

What is the difference between Emi Emc vs Electrical Engineer?

AspectEmi EmcElectrical Engineer
Required CredentialsCertification in EMI/EMC testing, technical trainingBachelor's degree in Electrical Engineering, possibly PE license
Work EnvironmentTesting labs, manufacturing facilities, R&D centersDesign offices, manufacturing plants, project sites
Industry UsageElectronics, telecommunications, automotive, aerospacePower systems, electronics, control systems, telecommunications

Emi Emc specialists focus on electromagnetic compatibility testing and compliance, often working in labs and testing environments. Electrical Engineers design, develop, and oversee electrical systems across various industries. While both roles require technical knowledge, Emi Emc professionals specialize in ensuring devices meet electromagnetic standards, whereas Electrical Engineers handle broader electrical system design and implementation.

How to become an EMI EMC engineer?

To become an EMI EMC engineer, typically a bachelor's degree in electrical engineering or a related field is required. Gaining experience with electromagnetic compatibility testing, understanding relevant standards, and obtaining certifications such as Certified EMC Engineer can enhance job prospects. Proficiency with testing tools and knowledge of circuit design are also important for this role.

Job description

About the job EMI EMC Engineer
About Castelion
Castelion is redefining defense development through rapid iteration, aggressive testing, and modern commercial manufacturing at scale. We design, build, and test next-generation long-range strike weapon systems to give the United States and its Allies a decisive advantage and deter future conflicts.
EMI/EMC Engineer
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.
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

Basic Qualifications
  • 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

Preferred Skills and Experience
  • 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

Key Outcomes
  • Avionics systems pass EMI/EMC validation and qualification. Own the electromagnetic compatibility performance of avionics hardware and ensure systems meet internal requirements and external standards prior to flight and production.
  • EMI risks are identified and mitigated early in hardware design. Partner with PCB, harness, and mechanical engineers to prevent interference issues before hardware reaches late-stage testing, reducing redesign cycles and accelerating hardware maturation.
  • Rapid diagnosis and resolution of electromagnetic interference issues. Lead root-cause analysis of EMI failures during integration and testing, implement mitigation strategies, and establish internal design guidelines to improve electromagnetic robustness across future avionics builds

Leadership Qualities
  • Bias to Action and Creative Problem Solving. Desire and experience questioning assumptions in ways that lead to break through ideas that are ultimately implemented. Successfully bring in applicable processes/concepts/materials from other industries to achieve efficiency gains. Ability to personally resolve minor issues in development without requiring significant support.
  • High Commitment, High Initiative. A successful candidate will have a genuine passion for Castelion's mission and consistently look for ways to contribute to the company's technical goals and prevent hardware blockers. Ability to work in a fast paced, autonomously driven, and demanding atmosphere. Strong sense of accountability and integrity.
  • Clear Communicator. Proactively communicates blockers. Trusted in previous roles to be voice of company with regulators, suppliers, gate keepers and customers. Capable of tactfully managing relationships with stakeholders to achieve company-desired outcomes without compromising relationships. Emails, IMs and verbal interactions are logical, drive clarity, and detailed enough to eliminate ambiguity.

ITAR Requirements

    Employment with Castelion is governed on the basis of competence and qualifications and will not be influenced in any manner by race, color, religion, gender, national origin/ethnicity, veteran status, disability status, age, sexual orientation, gender identity, marital status, mental or physical disability or any other legally protected status.
