Key Responsibilities

• Develop EMI/EMC requirements, design guidelines, and validation plans for new and existing products.

• Perform electromagnetic compatibility analysis and simulations to predict system behavior in noisy environments.

• Conduct hands-on EMI/EMC testing (radiated/conducted emissions and immunity) in accordance with relevant military, commercial, and internal standards (e.g., MIL-STD-461, DO-160, FCC, CE).

• Collaborate with hardware and systems engineers to design shielding, filtering, grounding, and layout strategies to mitigate EMI issues.

• Interface with test labs and compliance agencies as needed to support formal certification and qualification processes.

• Troubleshoot EMI-related failures and provide corrective actions for product improvements.

• Generate technical reports, test plans, procedures, and documentation to support design reviews and compliance audits.

• Bachelor’s or Master’s degree in Electrical Engineering, Physics, or a related field.

• 3+ years of relevant experience in EMI/EMC engineering (preferably in aerospace, defense, or high-performance systems).

• Strong understanding of EMI/EMC principles, design practices, and mitigation techniques.

• Experience with EMI test equipment (spectrum analyzers, LISNs, TEM cells, antennas, etc.).

• Familiarity with industry standards such as MIL-STD-461, IEC 61000 series, and FCC/CE requirements.

• Proficiency in simulation tools (e.g., CST, HFSS, or similar) for EMI/EMC modeling.

Preferred:

• Experience working in military or defense-related projects.

• Knowledge of PCB layout best practices for EMC.

• Ability to interpret system schematics and harness diagrams.

• Hands-on experience in troubleshooting EMI/EMC issues during design and validation phases.

Why Join Mach Industries?

• Be part of a mission-driven team redefining the frontier of energy and defense tech.

• Work in a fast-paced, innovative environment with real-world impact.

• Competitive salary, benefits, and career growth opportunities.
