Work directly with customers to understand the use case and define technical requirements including gas species, working pressure, required storage capacity, temperature range, fill and discharge profiles, service life, packaging envelope, interfaces, mounting, mass, cost, and environmental requirements. Perform and/or coordinate engineering analyses including pressure-load calculations, stress and strain assessment, fatigue and pressure-cycle life, thermal effects, tolerance stack-ups, material compatibility, permeation, weight, volumetric efficiency, and system-level load cases.
