San Jose, California, United States Stealth Startup Full time $120,000 - $180,000 per year

About the Company:

We are a stealth-mode battery startup developing cutting-edge battery technology. Our mission is to revolutionize battery technology to accelerate the global transition to clean energy.

By leveraging innovative materials, advanced manufacturing techniques, and next-generation energy storage architectures, we are building the future of sustainable energy.

About the Role:

We are seeking a 
CAE Mechanical Engineer
 to lead and execute high-fidelity structural

simulations for lithium-ion battery systems across the cell, module, and pack levels. This role is

integral to bridging design concepts into manufacturable, reliable hardware by modeling how

complex electro-mechanical systems behave under real-world conditions. You will work closely

with mechanical design, test, and manufacturing teams to inform design architecture through

simulation-driven insights and best practices.

Key CAE Responsibilities:

Simulation & Analysis


• Perform mechanical FEA under diverse loading conditions including crush, vibration,

drop, thermal expansion, swelling, crash and underbody impact.


• Build and refine detailed simulation models using CAD and empirical inputs, with rigorous

attention to mesh quality, materials, contacts, and boundary conditions.


• Conduct simulations using Abaqus, ANSYS, LS-DYNA, or similar tools; analyze results

to assess deformation, failure risk, and design sensitivity.


• Correlate simulation outputs with physical test data (e.g., strain gauges, displacements,

fracture behavior) to validate and improve model fidelity.


• Rapidly iterate on design alternatives and provide clear, actionable simulation feedback to

design teams.

Lead CAE Domains

Own analysis workflows for:


• First Mode and Modal Analysis


• Shock and Vibration Evaluation


• Underbody Impact Scenarios


• Side Pole Impact

CAE Development & Infrastructure


• Contribute to the selection and integration of solver tools, pre/post-processors, and overall

CAE infrastructure.


• Define, document, and continuously improve best practices and workflows to ensure

robust, repeatable analysis pipelines.


• Develop and validate material models for CAE use—ideally by designing and executing

custom test programs to generate material cards.

Fatigue & Advanced Simulations (Bonus)


• Support the development of fatigue analysis methodologies, particularly for polymers or

adhesive joints.


• Lay the foundation for in-house battery crash and impact simulation capabilities:


• Model mechanical behavior of cells during impact.


• Collaborate with OEMs on vehicle-level integration and crash safety strategy.

Cross-Functional Collaboration & Product Design

Component Design


• Partner with Product Development on mechanical hardware, especially:


• Underbody protective elements


• Structural enclosures


• Pack framing and load-bearing components

Compression System Innovation


• Contribute to the design and optimization of next-generation battery compression systems,

including advanced "quilted" or pre-formed plate concepts.

Qualifications & Experience


• B.S. or M.S. in Mechanical Engineering, Applied Mechanics, or related discipline.


• 5+ years of experience in mechanical FEA, ideally within battery systems or similar dense

electro-mechanical assemblies.


• Proven proficiency in FEA tools such as Abaqus, ANSYS, or LS-DYNA; deep

understanding of crash, vibration, and non-linear analyses preferred.


• Strong skills in model setup (meshing, contact definition, material property assignment,

boundary condition management).


• Demonstrated ability to correlate simulation to test data and validate model accuracy.


• Excellent communicator—capable of presenting simulation results, limitations, and trade-

offs to multidisciplinary teams.
• Comfortable working in fast-paced, iterative environments with evolving product requirements.

Why Join us?


• Innovative Technology: Work on cutting-edge energy storage solutions that power the

future.


• Career Growth: Opportunities to work on high-impact projects and advance in a growing

industry.
