About The Position

The EMI/EMC Design Engineer V/VI is a senior-level individual contributor responsible for building electromagnetic compatibility into Zone 5 Technologies’ products from the beginning of design. The role leads EMI/EMC practices across electronics, harnesses, and vehicle-level integration, ensuring UAS and weapon systems meet customer electromagnetic environmental effects (E3) requirements and pass qualification testing.

The engineer defines and flows down E3 requirements, creates and maintains control and test documentation, performs analysis and simulation, and conducts in-house pre-compliance testing. The role also supports formal qualification testing, investigates and resolves failures, reviews designs for EMC compliance, communicates E3 status to customers and at design reviews, and mentors electrical engineers.

Requirements

• Bachelor's degree in Electrical Engineering or a related field.
• 10 or more years of EMI/EMC design and test experience in aerospace, defense, or other high-reliability systems.
• Expert knowledge of MIL-STD-461, including CE102, CS101, CS114, CS116, RE102, and RS103, and MIL-STD-464.
• Strong understanding of electromagnetic theory, shielding, filtering, grounding, and PCB layout for EMC, including reviewing layouts in Altium.
• Hands-on experience with EMI test equipment, including spectrum analyzers, LISNs, current probes, and antennas.
• Proven ability to troubleshoot and resolve EMI/EMC failures.
• Excellent communication and technical writing skills.
• U.S. Person status due to export control regulations.

Nice To Haves

• Master's degree in Electrical Engineering.
• iNARTE or equivalent EMC certification.
• Experience with electromagnetic simulation tools such as CST Studio Suite, Ansys HFSS, or EMA3D.
• Experience with lightning, ESD, and HERO requirements for ordnance and weapon systems.
• Familiarity with DO-160 and MIL-STD-704.
• Experience with RF datalinks, antennas, and co-site interference.
• Active U.S. security clearance or ability to obtain one.

Responsibilities

• Lead EMI/EMC design across PCB layout, enclosure design, filtering, shielding, cable design, and bonding and grounding schemes.
• Interpret customer E3 requirements and flow down MIL-STD-461 and MIL-STD-464 requirements to subsystems and suppliers.
• Author and maintain E3 control plans, EMI test plans and procedures (EMITP), and EMI test reports.
• Perform EMI/EMC analysis and electromagnetic simulation to identify and mitigate coupling, emissions, and susceptibility risks early in design.
• Plan and conduct in-house pre-compliance scans and troubleshooting to reduce risk before formal qualification.
• Support formal EMI/EMC qualification testing at internal and external laboratories and lead failure investigations and fixes.
• Review schematics, layouts, and harness designs for EMC compliance and present E3 status at PDR, CDR, and TRR design reviews.
• Serve as the technical point of contact with customers on E3 requirements, test results, and waivers.
• Mentor electrical engineers in EMC design principles and best practices.

Benefits

• Comprehensive benefit package options, including medical, dental, vision, and life insurance.
• 401(k) with company match.
• Three weeks of paid time off each year.
• 40 hours of sick time.
• 12 annual company holidays.
• Professional development and career advancement opportunities.
