Job Summary

Traysar is seeking a highly motivated and experienced Production Engineer with deep expertise in hydraulic systems to join our team. This is a hands-on role focused on designing building integrating and commissioning the hydraulic systems that power our autonomous heavy machinery.

The ideal candidate has extensive experience building hydraulic circuits from the ground up selecting and integrating hydraulic components plumbing complete hydraulic systems and commissioning hydraulic power packs for heavy equipment or industrial machinery. The machines you help build will be deployed to destroy hundreds of miles of tunnels currently used for terrorist activities.

You will work alongside a multidisciplinary team of mechanical electrical and controls engineers and report to the Mechanical Team Lead.

• Own the design build and integration of complete hydraulic systems for autonomous heavy machinery.

• Design and assemble hydraulic circuits including hose routing manifolds valves pumps motors cylinders filters reservoirs accumulators and instrumentation.

• Specify size source and integrate hydraulic power units (HPUs) and power packs to meet system performance requirements.

• Develop hydraulic schematics and ensure they are translated into reliable manufacturable hardware.

• Coordinate the transition from detailed design to manufactured hardware taking full responsibility for bringing hydraulic systems into production.

• Serve as the primary interface with hydraulic suppliers hose manufacturers machine shops fabrication vendors and other external partners.

• Review and approve manufacturing drawings hydraulic schematics BOMs and assembly documentation before release.

• Lead on-site assembly plumbing commissioning bleeding flushing and troubleshooting of hydraulic systems.

• Diagnose and resolve hydraulic issues including pressure losses flow restrictions leaks heat generation contamination and system instability.

• Develop assembly procedures inspection plans test procedures and production documentation for hydraulic systems.

• Track component procurement supplier lead times system weight cost and production schedules.

• Support machine testing validation and field operations incorporating lessons learned into future designs.

• 7 years of professional experience working with hydraulic systems.

• Degree in Mechanical Engineering or a related engineering discipline or equivalent hands-on industry experience.

• Extensive experience designing building plumbing and commissioning hydraulic systems for heavy equipment mobile machinery construction equipment mining equipment agricultural equipment or industrial machinery.

• Strong mechanical background with hands-on experience assembling and troubleshooting hydraulic equipment.

• Experience reading and creating hydraulic schematics and mechanical drawings.

• Experience working from 3D CAD models and 2D manufacturing drawings.

• Extensive experience designing and assembling complete hydraulic power packs (HPUs).

• Strong understanding of hydraulic pumps motors proportional valves servo valves manifolds accumulators pressure control flow control filtration and cooling systems.

• Experience selecting hydraulic components based on pressure flow duty cycle efficiency and reliability requirements.

• Experience routing hydraulic hoses and tubing for serviceability manufacturability and reliability.

• Hands-on experience commissioning hydraulic systems including flushing bleeding contamination control and performance tuning.

• Experience troubleshooting complex hydraulic systems under field conditions.

• Experience working directly with hydraulic suppliers and component manufacturers.

• Strong understanding of manufacturing processes tolerancing and Design for Manufacturing (DFM/DFA).

• Experience working with CNC machining welding fabrication sheet metal and additive manufacturing suppliers.

• Proficiency with NX or SolidWorks.

• Experience taking complex electromechanical systems from prototype through production.

• Strong organizational communication and cross-functional coordination skills.

If there is a mutual fit well schedule two technical interviews. During the second interview youll present a project you are particularly proud of with a strong emphasis on the hydraulic or mechanical systems you personally designed built integrated or commissioned. Candidates who successfully complete the technical interviews will be invited for a final on-site interview.
