Mechanical Engineer - Structural Simulation

The posting, as DoorDash wrote it

About the Team

DoorDash Labs is the hardware and autonomy innovation engine at DoorDash. We design, build, and deploy custom robotics and autonomous delivery systems designed to operate safely, efficiently, and reliably in urban environments. We are currently kicking off development on our clean-sheet, next-generation robot platform—rethinking the mobility foundation from first principles to dramatically improve efficiency, payload dynamics, and service lifetime.

About the Role

As a Senior Structural Simulation Engineer (Level IC5) , you will be the foundational structural analysis authority for DoorDash Labs. You will own structural finite element analysis (FEA) across our next-generation robotic platform, working directly on core vehicle architecture—including chassis systems, suspension, closures, and sensor enclosures.

This role will be heavily focused on future-forward designs starting from the early concept phase. In your first 90 days, you will drive our architectural exploration, define early vehicle load cases, and make strategic software ecosystem decisions (including standardizing and driving our commercial commitments around simulation tools). As development advances, you will shift from rapid concept modeling to production-intent structural refinement and physical test-to-simulation correlation.

You’re excited about this opportunity because you will

• Build From Day Zero: Lead structural concept validation for a ground-up robotic platform, running high-velocity trade studies alongside chassis, suspension, and closures engineers.
• Define Our Tooling & Workflows: Evaluate, select, and operationalize our primary CAE/FEA software tech stack (with an emphasis on ANSYS-based suites), negotiating capabilities and technical fit directly with vendors.
• Establish Load Cases & Criteria: Formulate first-principles structural load cases, fatigue histories, stiffness benchmarks, and failure criteria for dynamic ground vehicle environments where little historical data exists.
• Simulate Critical Vehicle Subsystems: Execute complex static, dynamic, modal, durability, and fatigue analyses on structural enclosures, cast and sheet-metal subframes, linkages, and moving mechanisms.
• Drive Test-Simulation Correlation: Partner with physical test teams to correlate strain gauge, modal shaker, and dynamic field testing data back into simulation models to maximize predictive accuracy.
• Influence Primary Architecture: Act as the math-first checkpoint for mechanical design decisions, steering CAD geometry toward optimized strength-to-weight ratios before parts hit prototype tooling.

We’re excited about you because

• Deep Structural Domain Expertise: You bring 7+ years of hands-on structural FEA and mechanical simulation experience (or an advanced degree—MS/PhD—with 4+ years) focused on structural integrity, stiffness, fatigue life, and dynamic loading.
• Vehicle & Robotics Systems Background: You have a demonstrated track record analyzi
