Principal EMI/EMC Engineer

Responsibilities

• Establish comprehensive EMI/EMC requirements, specifications, control plans, and design guidelines for the launch vehicle and all subsystems, flowing down from platform-level needs to hardware.
• Perform analyses for conducted/radiated emissions & susceptibility, bonding/grounding, lightning direct/indirect effects, electrostatic discharge (ESD), triboelectric charging, multipaction, and spacecraft charging.
• Collaborate closely with avionics, RF, power, propulsion, structures, and software teams to integrate EMI/EMC best practices and mitigations early in the design cycle.
• Develop and execute EMI/EMC test plans and procedures, including pre-compliance screening, formal qualification, and system-level testing.
• Lead troubleshooting and root-cause investigations for EMI/EMC problems, implementing corrective actions and verifying effectiveness.
• Create and maintain all EMI/EMC documentation (requirements, analyses, test reports, verification matrices, and certification packages) to support internal reviews and external approvals.
• Define, procure, and/or oversee EMI/EMC test facilities and equipment; coordinate with external labs when needed.
• Ensure full compliance and certification against relevant standards, including MIL-STD-461G, MIL-STD-464D, NASA-STD-4003, NASA-HDBK-4002B, and applicable range safety / launch vehicle requirements.

Qualifications

• 5+ years of work experience in EMI/EMC engineering with direct involvement in aerospace systems (launch vehicles, spacecraft, or aircraft).
• Advanced degree in electrical engineering, physics, or related fields.
• Previous work experience with MIL-STD-461, MIL-STD-464, NASA-STD-4003 documentation.
• Knowledge of in-atmosphere and in-space EMI/EMC including effects of space plasma, charging, grounding, bonding, shielding, design for low radiated emissions, lightning, electromagnetic field coupling, Maxwell's equations, boundary conditions, image charge/current, and lumped element modeling.
• Knowledge of materials and their electrical properties including paint, anodize, alodine, surface finish, electrical conductivity, volume resistivity, surface resistance.
• Demonstrated experience troubleshooting EMI events from system to board level.
• Proficiency with EMI/EMC test equipment (spectrum analyzers, EMI receivers, antennas, LISNs, current probes, etc) and familiarity with simulation tools (SPICE, HFSS, CST, etc).
• Strong knowledge of RF principles and RF engineering.
• Experience in fast-paced work environment with flight hardware.
• Excellent verbal and written communication skills.
• Must be available to work primarily on-site in person from Stoke’s HQ in Kent, WARK.
