Electrical Engineer

Your Job

Molex is seeking an experienced Electrical Engineer to join our team in Naperville, IL. This role is responsible for specifying, architecting, designing and verifying electronic devices based on microcontrollers, sensors and radios. These IoT based designs are for the purpose of creating solutions for our customers in the marketplace of thin flexible BLE labels, human machine interfaces (HMI), and skin‑attached medical/wearable sensors.

An ideal candidate will have knowledge of wireless interfaces such as Bluetooth Low Energy (BLE), Near Field Communications (NFC), and Wi‑Fi. The Electrical Engineer will design battery‑powered electronics that utilize very low power modes to extend the life of the battery. We are seeking candidates who can select the components, design the schematic, do board layout, and bench‑level validate the result.

The Electrical Engineer should be able to provide clear directions for a test engineer to validate products. The ideal candidate enjoys the design challenge and investigates issues to improve the design based on design experience.

The Electrical Engineer reports to the Electrical Engineering Manager and works directly with mechanical engineers, costing engineers, quality engineers, test engineers, and technicians. They will lead projects and work hand in hand with mechanical engineering. The ideal candidate understands the importance of producing quality documentation, following a product development process, and utilizing a PLM system to maintain revision control.

Product specific focus areas include BLE smart labels and wearable skin patches. Our design team focuses on developing silver printed electronic devices and flexible polyimide copper circuits. If the product fits into focus areas, it may also utilize a standard FR4 based design. We assist customers in the development of unique flexible hybrid electronics.

• Innovate and work as part of a cross‑functional development team on product architecture, as well as the design implementation of sensor and radio devices.
• Lead the debug process and make design improvements to achieve optimal performance.
• Understand the customer's needs and apply the best technology to achieve it.
• Design electronic circuits using schematic capture and board layout.
• Select components and integrate them with a microcontroller with timers, interrupts, A/Ds, PWM's, etc.
• Study device specifications for electronic parts and select parts based on performance and cost trade‑offs.
• Execute board bring‑up activities to verify the full function of circuit using lab equipment such as oscilloscopes, power supplies, multimeter, etc.
• Utilize knowledge of basic serial communication such as USB, I2C, SPI, UART.
• Utilize experience with wireless communication protocols including Bluetooth and LoRa.
• Document design verification plans. Supports efforts in a reliability lab for execution of design validation (DV) and production validation (PV) tests when needed.
• Provides guidance to a test engineer for creating an End of Line (EOL) test solution.
• Estimate timelines for development work based on requirements and existing project workload and keep track of time spent on various projects.
• Research new technologies and propose ideas to advance our business unit's capabilities to stay ahead in the market.
• Utilize problem‑solving methodologies and Failure Mode Effects Analysis (DFMEA, PFMEA, 8D, and fishbones).
• Checks other engineers' schematics, board layouts, and fabrication drawings for completeness and accuracy.
• Create technical documentation to support product release based on individual project needs.
• Interface with internal departments (manufacturing, quality, lab, sales and marketing) to ensure design objectives are met.
• Utilize effective verbal and written communication skills that demonstrate the ability to express complex technical concepts clearly and concisely.
• Support Molex Quality Management by following approved policies and procedures.

• Bachelor's degree in one of the following:
  Electrical Engineering, Computer Science, or equivalent.
• 3+ years of experience in electrical engineering
• Proficient with circuit…
