THIS POSITION IS LOCATED IN JACKSONVILLE, ILLINOIS

Job Summary

We are seeking a detail-oriented Electrical Engineer / Test Specialist to support our electronics manufacturing and engineering teams. This role focuses on troubleshooting, testing, and validating electrical assemblies and systems. The ideal candidate will bring a strong understanding of electrical and electronic principles, hands-on lab experience, and the ability to analyze and resolve technical issues in a fast-paced manufacturing environment.

Essential Duties and Responsibilities

• Perform testing, troubleshooting, and validation of electronic assemblies and PCBs to ensure functionality and reliability.
• Work extensively with microcontroller-based systems (8-bit to 32-bit) and peripherals including RTC, Timers, ADC, DAC, PWM, Interrupts, DMA, Capture/Compare, and UART.
• Program and configure C compilers, work with and without RTOS environments, and interface with USB, TCP/IP, CAN, and Modbus RTU communication stacks.
• Support design-for-manufacturing activities, including PCB layout review (2–6 layers), component placement, and high-current/high-voltage considerations.
• Operate and maintain engineering pick-and-place equipment, including loading components, adjusting for odd shapes, and verifying placement accuracy.
• Perform fine-pitch SMT soldering and rework down to 0402 components using both leaded and lead-free solder.
• Assemble, test, and debug prototypes and pre-production units, ensuring alignment with engineering requirements.
• Develop and build test jigs, simulators, and fixtures, including wiring schematics, panel layouts, and safe use of hand tools.
• Operate and interpret results from oscilloscopes, logic analyzers, multimeters, waveform generators, spectrum analyzers, and high-voltage power supplies.
• Create and refine Bills of Materials (BOMs) by cross-referencing general components (resistors, capacitors, ICs, diodes, etc.) to in-house part numbers, ordering prototypes, and applying appropriate scrap factors.
• Maintain accurate, repeatable test data and assist in root cause analysis for production or field issues.
• Install and troubleshoot engineering software, firmware tools, and driver issues as needed for testing or production support.
• Perform data collection, feasibility analysis, and assist in process or product improvement initiatives.
• Collaborate with engineering, production, and quality teams to support builds, testing, and continuous improvement.
• Use Outlook, Word, Excel, SolidWorks, CAB, and online databases to locate technical documentation, data sheets, and component specifications.
• Perform other related duties as assigned.

Qualifications

• Bachelor’s degree in Electrical Engineering, Electronics Engineering Technology, or related discipline (or equivalent hands-on experience).
• 3 years of experience in electronics testing, troubleshooting, or manufacturing support.
• Solid understanding of microcontroller architectures, embedded systems, and communication protocols.
• Skilled in use of test and measurement equipment for signal tracing and circuit validation.
• Hands-on experience with SMT soldering, rework, and prototype assembly.
• Strong mechanical aptitude and fine motor skills for working with small components and lab tools.
• Excellent documentation, organization, and communication skills.
• Ability to work both independently and collaboratively in a fast-paced environment.

This role offers a diverse, hands-on experience supporting a wide range of electronic products. The right candidate will thrive in a practical environment that values precision, teamwork, and continuous improvement.
