Mechanical Engineer
$60–$90 / hourRemote · US
We are hiring experienced mechanical engineers to work directly with a leading AI lab's research and program management teams, improving how frontier AI models reason about real mechanical engineering work.
Join a leading AI lab's cutting-edge GenAI team to be at the core of the AI revolution, where your expertise fuels the development of the most advanced AI models.
1. Overview
We are hiring experienced mechanical engineers to work directly with a leading AI lab's research and program management teams, improving how frontier AI models reason about real mechanical engineering work.
Your engineering judgment is the substance of this role. You will review the quality of mechanical engineering tasks and model outputs, write the instruction specs and reference solutions that define what "correct" looks like, and help build the evaluations that show whether the model is genuinely improving. We are looking for practicing engineers who have owned real designs, analyses, or systems in industry, not generalists.
This is a W-2 employment position with Cincinnatus LLC, with the opportunity to be placed at a leading AI lab as part of their extended workforce. The initial engagement is 2 to 3 months, with a strong possibility of extension based on performance and project needs. You will be provisioned with client-issued accounts and equipment, and will work inside the client's own tools alongside their research teams.
Location: Remote, within the United States.
2. Key Responsibilities
- Data QA and reviews: Vet the quality of mechanical engineering tasks and model outputs, spotting incorrect assumptions, missing constraints, unit and tolerance errors, unsafe design choices, and answers that read well but would not pass a design review.
- Instruction specs and reference solutions: Write clear instruction specs, produce worked reference solutions to mechanical engineering problems, and define new tasks that reflect how engineering work is actually done in practice.
