Heven Aero Tech is hiring a Hydrogen Test Engineer in Winchester, Virginia to verify that our hydrogen production systems — electrolyzers, compression, storage, and fueling equipment — perform to specification before leaving the factory and after field installation.

You’ll design, execute, and document Factory Acceptance Test (FAT) and Site Acceptance Test (SAT) procedures; instrument test setups with electronic loads and data acquisition hardware; and partner with engineering, production, and quality teams to troubleshoot failures and drive corrective action. In doing so, you’ll build the test discipline underpinning the hydrogen systems that power our long‑endurance UAS platforms for defense, public safety, and commercial customers.

• Develop, document, and execute Factory Acceptance Test (FAT) and Site Acceptance Test (SAT) procedures for hydrogen production systems, including electrolyzers, compressors, storage, and fueling equipment.
• Maintain test setups using electronic loads, data acquisition (DAQ) hardware, and sensors to characterize performance, efficiency, and safety margins.
• Execute performance, endurance, and environmental test campaigns, and record, analyze, and report results against system specifications and acceptance criteria.
• Perform leak checks, pressure testing, and commissioning procedures on high‑pressure hydrogen systems prior to customer delivery and installation.
• Support on‑site SAT activities at customer or field locations, coordinating logistics, safety planning, and troubleshooting for installed systems.
• Troubleshoot test failures and non‑conformances in collaboration with fuel cell and hydrogen systems engineering, driving root‑cause analysis and corrective action.
• Maintain and calibrate test equipment, DAQ systems, and instrumentation, and support development of new test fixtures and stands as product lines expand.
• Support hazard analyses (HAZOP, FMEA) and ensure test procedures and facilities comply with applicable codes and standards, including NFPA 2, ASME, and CGA.
• Maintain detailed test records, data packages, and certificates of conformance to support quality, program, and customer requirements.

• Bachelor’s degree in mechanical engineering, Electrical Engineering, Chemical Engineering, or related technical discipline, OR equivalent hands‑on test engineering experience.
• 3–6+ years of experience testing electromechanical, fluid, or power systems, including developing and executing formal test procedures (FAT/SAT, qualification, or acceptance testing).
• Hands‑on experience with electronic loads, power supplies, and data acquisition (DAQ) systems for capturing and analyzing test data.
• Experience with high‑pressure gas or fluid systems (300+ bar), including pressure testing and leak detection methods.
• Experience reading and working from engineering drawings, P&IDs, and test specifications.
• Working knowledge of relevant codes and standards (ASME B31.2/B31.3, CGA guidelines, or similar).
• Strong troubleshooting skills and comfort working hands‑on with hardware in a lab or production environment.
• Clear, disciplined documentation habits, with the ability to produce test reports and data packages that others can rely on.

• Direct experience testing electrochemical and/or hydrogen equipment.
