Senior EMC Engineer

EMC Engineer

Rochester Hills, Michigan | Onsite | Travel: Less than 10%| Engineering | EMC Product Validation

Your Job

In this role, you will have meaningful technical ownership, work hands-on to solve complex EMC challenges, and directly influence product design decisions for current and future connector platforms.

The methods, design guidance, and engineering knowledge you develop will help strengthen how Molex designs and validates advanced connector systems.

You will work directly with product development teams from early design evaluation through validation and failure investigation.

Rather than simply executing established tests, you will determine whether an issue originates in the product, fixture, calibration approach, contact interface, grounding path, or measurement system.

You will communicate EMC risk, identify the design parameters that matter most, and help engineering teams make informed product decisions.

Molex is seeking a Senior EMC Engineer to own the electromagnetic performance and validation of high-voltage and high-speed automotive connector systems.

This is a hands-on engineering role for an experienced EMC professional who enjoys working in the laboratory, investigating unexpected results, understanding the physics behind connector performance, and translating technical findings into practical design recommendations.

What You Will Do



* Own EMC performance and validation for assigned high-voltage and high-speed automotive connector programs, from early design evaluation through validation, root-cause investigation, design refinement, and technical release recommendations.


* Partner with product engineering teams during design development to identify EMC risks, evaluate proposed concepts, and recommend changes to shielding geometry, interfaces, grounding paths, shield termination, material selection, packaging, and other critical design parameters.


* Develop and execute EMC and shielding-characterization plans for connectors, cable assemblies, shielding interfaces, and related components.


* Perform hands-on laboratory testing using Vector Network Analyzers and other relevant EMC/RF measurement equipment.


* Lead troubleshooting when results are unexpected or inconsistent.

Determine whether the source is the product, fixture, calibration, cable, contact interface, grounding path, noise floor, or broader measurement system.


* Apply electromagnetic fundamentals and controlled experiments to explain why a design is producing a particular result, not simply whether it passed or failed.


* Evaluate transfer impedance, shielding effectiveness, screening attenuation, coupling attenuation, S-parameters, and related performance measures.


* Define calibration, reference-plane, fixture, and de-embedding strategies appropriate to the measurement objective.


* Design controlled experiments to assess the effects of shield termination, seams, apertures, contact interfaces, materials, surf...
