This person has strong fundamentals while bringing a practical and can-do attitude to the role.

Responsibilities:

Structural Analysis

• Guide and inform Energy Storage System structural design:
• Define relevant loading conditions, analysis and validation strategy
• Perform detailed static and dynamic structural analysis of systems and components, determining stress, strain, frequency response, and fatigue characteristics using first principles, hand calculations, and FEA.
• Propose design modifications to enhance structural reliability and performance

Simulation and Modeling

• Develop and validate simulation models for structural analysis
• Utilize advanced computational tools and techniques, such as finite element analysis (FEA)

Testing and Validation:

• Design and oversee experimental tests to validate models and predictions
• Work with test engineers to analyze and correlate test data, and to incorporate findings into simulation model and design improvements

Collaboration and Communication

• Work closely with cross-functional teams, including development, manufacturing, and quality assurance
• Present analysis results and recommendations to technical and non-technical stakeholders
