• Develop and optimize hydraulic systems, including pump/motor selection, circuit design, and performance tuning.
• Ensure seamless electrical integration of powered accessories with truck OEM or aftermarket power and control systems.
• Create and maintain detailed engineering documentation: drawings, BOMs, engineering change orders, and test reports.
• Support validation testing, including environmental, fatigue, load, and field testing.
• Engage with suppliers and customers to define requirements, resolve technical challenges, and ensure product compatibility.
• Support continuous improvement in product performance, cost, and manufacturability.

• Experience and success designing heavy duty industrial products.
• Knowledge of design principles particularly related to large multicomponent assemblies (5-15 years of experience).
• Engineering knowledge to evaluate test results to determine if design meets functional and performance specifications.
• Experience evaluating and solving design related issues that arise within manufacturing and/or production assembly.
• Excellent communication skills and proven experience interacting with other groups to finalize product designs.
• Disciplined, motivational personality who is self-motivated, results oriented, and capable of sustained and continuous effort.
• Hands-on approach and mechanical aptitude.
• Pride and commitment to accuracy, detail, and well thought out designs.
• Thorough and consistent documentation habits paired with excellent organizational and management skills.
• Ability to work effectively within a fast-paced product design team.

• Bachelor's in Mechanical Engineering or related field.
• Proficient in CAD, with a strong emphasis on Creo.
• Background in Mechanical Engineering and New Product Development.
• Experience designing heavy-duty truck mounting assemblies is a strong plus.
• Experience doing 3D designs in Creo is a strong plus.
