What is a stealth startup?

A stealth startup is a new business that operates in secret, keeping its products, services, or business model hidden from the public and competitors during its early development stages. This approach allows the company to protect its intellectual property, avoid early competition, and refine its offerings before a public launch. Stealth startups may also use this period to build a strong team, develop their technology, and seek funding, all while maintaining a low profile.

What are the key skills and qualifications needed to thrive at a stealth startup, and why are they important?

To thrive at a stealth startup, you need a strong entrepreneurial mindset, adaptability, and experience in your area of expertise, often supported by a relevant degree or startup experience. Familiarity with project management tools, collaboration platforms, and, depending on your role, technical stacks like coding languages or design software is common. Initiative, resilience, and excellent communication are critical soft skills in this fast-paced, ambiguous environment. These skills enable you to navigate uncertainty, drive innovation, and contribute meaningfully to early-stage company growth.

What are some common challenges when joining a stealth startup, and how can I prepare for them?

Joining a stealth startup often means working with limited information about the company's product or market until launch, which can create ambiguity in your day-to-day tasks. You may also encounter rapidly changing priorities as the business pivots and iterates on its core idea. To succeed, it's helpful to be adaptable, proactive in seeking clarification, and comfortable making decisions with imperfect information. Strong communication skills and a collaborative mindset are vital, as teams are usually small and cross-functional, requiring frequent collaboration and flexibility.

Job description

Location: San Jose, CA
Employment Type: Full-Time
About the company:
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.
