Product Functional Test Technology Engineer

About the role

We are looking for a talented JTC Test Engineer to join our team in Jamestown, NY. In this role, you will plan, coordinate, and execute engine and vehicle component testing programs that drive heavy-duty product development and validation. You will own testing end to end — from test planning and hardware procurement through test article build, execution, data analysis, and post-test closure — while ensuring every phase meets established engineering procedures, standards, and safety requirements. Success in this role calls for a strong grounding in diesel engine performance fundamentals and the confidence to troubleshoot complex issues spanning engines, test systems, instrumentation, controls, and facility infrastructure. Working alongside engineering teams, technical specialists, and test operations personnel, you will lead investigations, diagnose root causes, and implement corrective actions that keep testing safe, efficient, and on schedule. Familiarity with Cyflex, Calterm, and data acquisition systems will allow you to validate data quality quickly and deliver CTRs, teardown reviews, and technical recommendations that engineering can act on.

Responsibilities

• Develop and execute test plans that support heavy-duty product development and validation.
• Coordinate hardware procurement, instrumentation requirements, and test article builds to keep scheduled testing on track.
• Ensure all testing is conducted in accordance with established engineering procedures, standards, and safety requirements.
• Monitor test progress and validate data quality, resolving technical issues before they compromise results or schedule.
• Analyze test data and deliver CTRs, summaries, and technical recommendations that inform product decisions.
• Lead and document post-test activities, including teardown inspections and review meetings.
• Troubleshoot and repair issues across engine systems, test cell equipment, instrumentation, controls, and facility systems to minimize downtime.
• Collaborate with cross-functional engineering teams to advance validation outcomes and continuous improvement initiatives.
• Apply sound engineering judgment to identify root causes and implement effective corrective actions.
• Maintain accurate test documentation and communicate project status, risks, and results to stakeholders.

Requirements

• A working knowledge of diesel engine performance fundamentals and engine systems, applied to real test outcomes.
• Hands-on experience with engine testing, instrumentation, controls, data acquisition systems
