• Support development of machine architecture, system requirements, and performance specifications.  
• Work closely with mechanical design, software, and test engineers to integrate and validate machine systems.  
• Investigate and resolve machine performance issues through root cause analysis and engineering problem-solving techniques.  
• Translate customer, operator, and field feedback into measurable product improvements.  
• Support product development efforts from concept, prototyping, and validation through production launch.  
• Create engineering documentation, test reports, validation plans, and system performance summaries .

Requirements

• Bachelor’s degree in Mechanical Engineering, Electrical Engineering, Agricultural Engineering, Robotics, or a related engineering field.
• Understanding of machine systems including hydraulics, powertrains, drivetrains, thermodynamics, or vehicle dynamics.  
• Experience through internships, co-ops, academic projects, or professional engineering roles involving mechanical systems, testing, or product development.  
• Familiarity with engineering analysis, modeling, and simulation tools such as MATLAB, Simulink, ANSYS, Amesim, or similar platforms.  
• Experience collecting, analyzing, and interpreting engineering test data.  
• Strong analytical, troubleshooting, and mechanical problem-solving skills.  
• Ability to communicate technical concepts and work effectively within multidisciplinary engineering teams. 

Desired Attributes

• Experience developing or validating mobile equipment, agricultural equipment, construction equipment, automotive systems, or other off-highway machinery.
• Knowledge of hydraulic system design, performance analysis, and troubleshooting.  
• Familiarity with powertrain systems, vehicle dynamics, transmission systems, or machine implement controls.  
• Experience conducting laboratory, field, or vehicle testing.  
• Proficiency with data acquisition systems, instrumentation, sensors, and machine diagnostics.  
• Exposure to control systems development, machine automation, or robotics.  
• Experience with MATLAB/Simulink, Simscape, Amesim, CANalyzer, CANape, or similar engineering tools.  
• Hands-on experience operating, testing, or evaluating heavy equipment and machinery.

Visa sponsorship is NOT available for this position.

Pay Range: $70,000-$100,000 – Commensurate with experience
