About the Job

Requirements

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

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 pre-compliance scans and troubleshoot issues in-house to reduce risk before formal qualification.
  • Support formal EMI/EMC qualification testing at internal and external labs, and lead failure investigations and fixes.
  • Review schematics, layouts, and harness designs for EMC compliance and present E3 status at design reviews (PDR, CDR, and TRR).
  • 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.

Desired Qualifications

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

About the Company

Zone 5 Technologies

Aerospace engineering and high-volume munitions production

Zone 5 designs and builds unmanned aircraft systems and low-cost missiles for defense, serving as a prime DoD contractor with vertical integration from concept to production. Its products, like the Rusty Dagger cruise missile, Paladin UAS for autonomous counter-drone missions, and White Spike for counter-UAS and precision strikes, are engineered for high-volume, low-cost production with modular avionics for fast fielding. It differentiates itself by a production-first approach that aims to cut unit costs and shorten development timelines, delivering a flight-ready system within about four months, and by controlling design and manufacturing in-house as a vertically integrated contractor; in 2026 it became a mostly-owned subsidiary of Kongsberg Defence & Aerospace. Its goal is to provide affordable, scalable munition and counter-UAS solutions for the DoD and allied forces.
