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.
