• Develop, modify, and optimize laboratory equipment, manufacturing tooling, fixtures, and prototype systems to improve capability, reliability, safety, and throughput.
• Plan, execute, and document engineering experiments that reduce technical uncertainty and generate actionable engineering knowledge.
• Collaborate closely with design engineers, analysts, technicians, software engineers, and operations personnel to rapidly iterate hardware designs.
• Design and implement instrumentation, data acquisition, automation, and control solutions supporting laboratory testing.
• Troubleshoot multidisciplinary hardware systems using first-principles engineering methods, empirical testing, and systematic root cause analysis.
• Produce engineering documentation including design packages, test procedures, operating procedures, technical reports, and design review materials.
• Support commissioning, operation, maintenance, and continuous improvement of laboratory infrastructure and experimental facilities.
• Provide technical guidance to less-experienced engineers and technicians and may coordinate or direct technical tasks within assigned areas of work.
• Other duties as assigned.

Qualifications

• Bachelor's degree in Mechanical Engineering, Electrical Engineering, Mechatronics, Engineering Physics, or related engineering discipline or equivalent demonstrated experience developing complex multidisciplinary engineering systems.
• 5+ years of experience designing, building, integrating, testing, commissioning, or troubleshooting experimental hardware or electromechanical systems.
• Experience developing laboratory equipment, prototype systems, manufacturing tooling, robotics, automation systems, or research infrastructure.
• Demonstrated experience integrating mechanical, electrical, instrumentation, pneumatic, or software systems.
• Experience with CAD and mechanical design.
• Experience with instrumentation, data acquisition, controls, LabVIEW, PLCs, Python, embedded systems, or similar engineering tools is desirable.
• Experience in nuclear, aerospace, robotics, scientific instrumentation, semiconductor, or other advanced technology environments is preferred.

Knowledge, Skills & Abilities:

• Demonstrated ability to solve ambiguous technical problems through a combination of engineering reasoning, experimentation, and hands-on implementation.
• Strong understanding of mechanical systems, fabrication methods, precision assembly, and prototype development.
• Working knowledge of electrical systems, sensors, instrumentation, control hardware, and data acquisition.
• Knowledge of and ability to apply applicable laboratory and engineering safety practices when designing, building, testing, and operating experimental hardware.
• Ability to develop test approaches, evaluate experimental data, and draw technically supported conclusions to inform engineering decisions.
• Ability to rapidly learn unfamiliar technologies and apply them to engineering problems.
• Ability to design, build, test, modify, and optimize multidisciplinary engineering systems.
• Strong troubleshooting and root cause analysis skills spanning mechanical, electrical, software, and process domains.
• Ability to balance analytical engineering with practical implementation and rapid iteration.
• Excellent written and verbal technical communication skills.
• Ability to collaborate effectively with engineers, technicians, machinists, software developers, and operations personnel.
• Demonstrated curiosity, initiative, and sound engineering judgment when working with incomplete information.

Physical Demands

• Remaining in a stationary position, often standing, or sitting for prolonged periods
• Moving about to accomplish tasks or moving from one worksite to another
• Adjusting, moving, transporting, installing, positioning, or removing objects up to 20 pounds in all directions
• Communicating with others to exchange information
• Use hand tools

Environmental Conditions
