Mechanical Engineer - Simulation Specialist

About the job

Mercor connects elite creative and technical talent with leading AI research labs. Headquartered in San Francisco, our investors include Benchmark, General Catalyst, Peter Thiel, Adam D'Angelo, Larry Summers, and Jack Dorsey.

Position: Mechanical Engineering & Simulation Expert — Hephaestus
Type: Contract
Compensation: $70–$90/hour
Location: Remote

Role Responsibilities

• Create realistic engineering problems with native geometry, assemblies, materials, loads, boundary conditions, and design requirements.
• Build and debug analysis models in areas such as stress and deformation, thermal behavior, vibration, or fluid flow. Assess mesh quality, convergence, sensitivity, and physical consistency for simulation tasks.
• Produce reference solutions and reproducible CAD, FEA, or CFD workflows using tools like SolidWorks, FreeCAD, CATIA, ANSYS, CalculiX, OpenFOAM, or equivalents.
• Define checks for dimensions, assembly relationships, mass properties, manufacturability, stress, displacement, temperature, pressure drop, or other relevant outputs. Apply numerical checks, artifact inspection, and engineering judgment where appropriate.
• Package native files, solver settings, scripts, and results. Document assumptions and limitations for reproducibility.
• Validate reference outcomes and incorrect cases. Review AI-generated artifacts and diagnose failures from design, model setup, numerical method, or verification logic.

Qualifications

Must-Have

• 5+ years of professional mechanical engineering experience with direct ownership of product designs, engineering analysis, manufacturing processes, or validation.
• Recent hands-on depth in one or more relevant CAD, FEA, CFD, or thermal-analysis workflows.
• Ability to automate analysis or inspect results using Python, MATLAB, shell scripts, or comparable tools.
• Strong judgment about model fidelity, material behavior, boundary conditions, numerical convergence, and physical plausibility.
• Clear technical communication and a disciplined approach to reproducible engineering work.

Preferred

• A professional engineering credential.
• Prior test automation, design documentation, or engineering-training experience.
