Job description

Description

JOB PURPOSE or JOB SUMMARY:

The Principal Application Engineer serves as JEM's technical authority for hydraulic and electro-hydraulic systems, leading the development of innovative products and solving complex customer application challenges. This position provides technical leadership across new product development, advanced application engineering, prototype validation, and field support while establishing engineering best practices and mentoring engineers across the organization.

Working across Sales, Engineering, Manufacturing, Quality, and key customers, the Principal Application Engineer translates emerging market needs into new products, validates advanced hydraulic systems, and resolves the company's most technically challenging application issues.

Unlike a management role, this position leads primarily through technical expertise, innovation, and influence rather than direct personnel supervision.

ESSENTIAL DUTIES and RESPONSIBILITIES:

New Product Development

• Lead development of new hydraulic components, assemblies, and integrated systems from concept through validation and production launch.
• Define technical requirements, system architecture, validation plans, and performance criteria.
• Lead design reviews, technical risk assessments, prototype evaluations, and product validation activities.
• Identify opportunities for new products, technologies, and improvements based on customer and market needs.

Design & Documentation

• Create and review hydraulic schematics, 3D CAD models, 2D drawings, system layouts, and technical specifications.
• Lead integration of valves, manifolds, sensors, actuators, and control components.
• Maintain accurate engineering documentation within PDM and ERP systems.
• Lead or support engineering change processes and development of design standards and best practices.

Machine & Field Support

• Lead troubleshooting of complex customer machine issues, field failures, prototype concerns, and production problems.
• Perform system-level root-cause analysis using hydraulic measurements, data acquisition, schematics, and machine observations.
• Develop and validate corrective actions and design improvements.
• Support customer site visits, commissioning, field testing, and troubleshooting as required.

Technical Leadership & Collaboration

• Provide technical guidance and mentoring to engineers and technicians.
• Lead technical reviews and serve as an escalation point for complex engineering issues.
• Share lessons learned, engineering standards, and best practices across the organization.
• Work closely with sales, quality, operations, manufacturing, purchasing, and customers to align technical and business objectives.
• Engage directly with customers to clarify requirements, provide technical support, and ensure product performance meets expectations.

Other Duties

• Maintain compliance with JEM policies, ISO, OSHA, and AWAIR standards.
• Uphold JEM’s mission, vision, and core values in all interactions.
• Perform additional duties as assigned to support business and engineering needs.

An individual in this position must be able to successfully perform the essential duties and responsibilities listed above. Reasonable accommodations may be made to enable individuals with disabilities to perform the essential functions of this position.
