• Track trainee certifications and maintain training records
• Serve as the day-to-day technical point of contact for assigned DoD customers and program offices regarding hydrogen ground systems
• Gather and communicate customer requirements, operational feedback, and field observations back to the Heven AeroTech engineering team
• Support program reviews, site visits, and government-led evaluations as the hydrogen ground systems subject matter expert
• Build and maintain strong working relationships with military counterparts, contracting officers, and program managers
• Work with hydrogen equipment vendors to understand best practices and maintenance procedures.
• Provide on-site technical support and troubleshooting for hydrogen generation, storage, and fueling systems at customer locations, including CONUS and potential OCONUS deployments
• Perform scheduled maintenance, inspections, and pre/post-operation checks on expeditionary hydrogen systems per established procedures
• Identify recurring field issues and work with the engineering team to develop corrective actions and procedure updates
• Maintain accurate field service records, equipment logs, and maintenance documentation

• Ability to repeatedly load, unload, assemble, and disassemble hydrogen ground support equipment, hoses, fittings, cables, storage vessels, and associated field systems
• Ability to safely operate around compressed gases, pressurized systems, electrical equipment, and industrial machinery while adhering to OSHA, NFPA, and DoD safety protocols
• Ability to wear required personal protective equipment (PPE), including flame-resistant clothing, eye and hearing protection, gloves, respirators, and safety footwear, as required by operational conditions
• Ability to visually inspect equipment, read gauges and instrumentation, identify leaks or hazards, and distinguish color-coded indicators, warning lights, and labeling systems
