CAD / Mechanical Design Specialist Full Time

About Ambitus AI:

Ambitus AI is an applied-AI product and research company. Our work helps frontier labs and top enterprises train, test, and deploy AI agents that automate high ROI tasks.

We’re a highly technical team based in San Francisco with backgrounds from Mercor, Google, Stanford, and more.

As a CAD / Mechanical Design Specialist, you’d help us create training data for a project with one of the world’s top AI labs.

Your role:

As a CAD / Mechanical Design Specialist, you will apply your professional experience in parametric modeling and mechanical design to help design, execute, and evaluate realistic CAD workflows. The core objective of this role is to translate real, day-to-day mechanical design reasoning into structured tasks and evaluations, enabling AI systems to learn how experienced engineers and product designers model functional, manufacturable parts.

Compensation:

• Compensation: $40-60/hour
• Commitment: 15-40 hours per week
• Type: Contract, part-time
• Location: Fully remote

What you’ll do:

• Execute tasks within FreeCAD to validate feasibility and establish ground-truth solutions
• Write detailed task specifications for mechanical design workflows, including clear prompts, expected outputs, and grading criteria
• Model parametric parts and assemblies, apply dimensional constraints, and produce technical drawings
• Define grading rubrics that assess both technical execution (e.g., correct sketch constraints, valid feature trees) and engineering judgment (e.g., manufacturability, appropriate tolerancing, wall thickness)
• Provide clear, written documentation of your workflows, reasoning, and quality assessments

What we’re looking for:

We are specifically seeking experienced mechanical designers and product engineers with strong parametric CAD skills and hands-on production experience.

Relevant Backgrounds:

• Proficiency and fluency with FreeCAD, SolidWorks, Fusion 360, Onshape, or similar parametric CAD tools
• Mechanical designers, product engineers, or manufacturing engineers working in industry
• Freelance CAD designers with a portfolio of fabricated parts or assemblies
• Hands-on experience with sketching, parametric modeling, assembly constraints, and technical drawing generation
• Familiarity with manufacturing processes and design-for-manufacturability principles
