The Senior Structural Simulation Engineer at DoorDash Labs will be a key authority in structural analysis for the next-generation robotic platform. This role focuses on structural finite element analysis (FEA) and involves working on core vehicle architecture, including chassis systems and sensor enclosures. The engineer will lead early concept validation and define vehicle load cases while making strategic decisions regarding simulation tools. The position requires a blend of deep technical expertise and the ability to thrive in an ambiguous, fast-paced environment.

• 7+ years of hands-on structural FEA and mechanical simulation experience, or an advanced degree with 4+ years of experience.
• Demonstrated track record analyzing moving vehicle architectures such as automotive body-in-white, chassis frames, or robotics.
• Advanced user of industry-standard finite element solvers, with a preference for ANSYS Mechanical/Workbench.
• Strong mathematical and classical mechanics fundamentals.
• Ability to thrive in early-stage product definitions with fluid requirements.

• Lead structural concept validation for a ground-up robotic platform.
• Evaluate, select, and operationalize the primary CAE/FEA software tech stack.
• Formulate first-principles structural load cases and failure criteria.
• Execute complex static, dynamic, modal, durability, and fatigue analyses.
• Partner with physical test teams to correlate testing data back into simulation models.
• Act as the math-first checkpoint for mechanical design decisions.
