Boston MA

Are you a mechanical engineer with a passion for solving complex structural challenges? Want to shape the future of energy storage systems? We’re looking for a highly skilled Mechanical Engineer with deep expertise in Structural Finite Element Analysis (FEA) to join their dynamic engineering team and help design, validate, and optimize cutting-edge energy storage technologies.

About the Role:

As a core member of the mechanical design team, you’ll lead structural analysis efforts across a range of energy storage products — from cell enclosures to full battery systems. Your insights will directly inform design decisions, improve safety, and ensure the durability and reliability of our products in demanding environments.

Key Responsibilities:

• Perform detailed structural FEA on mechanical components and assemblies of energy storage systems (static, dynamic, thermal, fatigue, crash/load case scenarios).
• Collaborate with cross-functional teams to influence product architecture, material selection, and manufacturing processes.
• Validate simulation results with physical testing and iterate designs accordingly.
• Develop and maintain best practices for FEA modeling, meshing, and boundary conditions specific to battery systems.
• Contribute to design reviews and provide technical documentation to support certification and compliance.

What We’re Looking For:

• Bachelor’s or Master’s degree in Mechanical Engineering or a related field.
• 8+ years of experience in structural FEA (experience with battery or energy storage systems is a plus, but experience in Automotive or Aerospace also considered).
• Proficiency with simulation tools such as ANSYS, Abaqus, or COMSOL.
• Strong understanding of material behaviour, mechanics, and structural failure modes.
• Experience working with CAD tools (SolidWorks, CATIA, or similar).
• Excellent problem-solving skills and attention to detail.
• Bonus: Exposure to thermal or multi-physics simulations.
