  • 0-6 years of engineering experience in product development, design, testing, or manufacturing environments
  • Experience creating 3D models and engineering drawings using CAD tools
  • Understanding of geometric dimensioning and tolerancing (GD&T) and tolerance analysis principles
  • Experience supporting design, build, and test development cycles
  • Familiarity with requirements management, documentation, and verification processes
  • Knowledge of Design Failure Mode and Effects Analysis (DFMEA) methodologies
  • Experience with Computational Fluid Dynamics (CFD) and/or Structural Finite Element Analysis (FEA)
  • Knowledge of seal and gasket design principles
  • Fundamental understanding of fluid dynamics, heat transfer, mechanics of materials, and mass transport
  • Experience with electrochemical technologies such as electrolyzers, fuel cells, batteries, or related energy systems is preferred
  • Strong problem-solving skills with a willingness to challenge assumptions and seek innovative solutions
  • Self-motivated, hands-on, and able to work effectively in a fast-paced, highly collaborative environment
  • Demonstrated ability to take initiative, identify opportunities for improvement, and drive solutions forward
