Job description

We are sharing a full-time opportunity for experienced Mechanical Engineers with strong expertise in mechanical design, engineering analysis, manufacturing, thermal and fluid systems, structural evaluation, and technical problem-solving to support advanced AI research and model-evaluation initiatives.

Selected professionals will apply real-world engineering judgement to review mechanical-engineering tasks and AI-generated outputs, develop instruction specifications and reference solutions, and create challenging evaluations grounded in authentic industry practice. The role is designed for practising engineers who have owned real designs, analyses, or systems rather than generalist reviewers.

Key Responsibilities

Mechanical Engineering Review & Quality Assurance

• Review mechanical-engineering tasks and AI-generated outputs for technical accuracy
• Identify incorrect assumptions, missing constraints, unit errors, and tolerance issues
• Flag unsafe or impractical design choices
• Assess whether proposed solutions would withstand professional design review
• Provide precise written feedback explaining technical weaknesses and corrections

Instruction Specifications & Reference Solutions

• Write clear instruction specifications for mechanical-engineering tasks
• Develop worked reference solutions demonstrating correct engineering approaches
• Define assumptions, constraints, calculations, and expected outputs
• Create realistic problems reflecting professional engineering workflows
• Translate practical engineering judgement into explicit evaluation criteria

Mechanical Design & Engineering Analysis

• Develop and evaluate tasks involving mechanical design and product development
• Apply expertise across thermal, fluid, structural, stress, and manufacturing scenarios
• Review FEA, CFD, drawings, specifications, and engineering calculations where relevant
• Assess design choices against real-world performance and production requirements
• Apply appropriate engineering standards and design-review practices

Benchmarks & Technical Evaluation

• Design challenging benchmarks that test advanced mechanical-engineering reasoning
• Develop evaluation sets spanning design, manufacturing, controls, and system analysis
• Identify edge cases that distinguish robust reasoning from plausible but incorrect answers
• Support development of domain-specific engineering evaluation toolsHelp measure model performance against professional engineering standards

Research Collaboration & Calibration

• Collaborate with researchers and specialists across adjacent engineering disciplines
• Participate in calibration activities to maintain consistent evaluation standards
• Explain technical decisions, trade-offs, and failure modes clearly
• Convert tacit engineering experience into repeatable assessment criteria
• Support continuous refinement of engineering tasks, benchmarks, and reference materials

Ideal Profile

• Bachelor's degree or higher in Mechanical Engineering or a closely related engineering discipline
• 5+ years of hands-on professional mechanical-engineering experience
• Experience in areas such as product development, thermal and fluid systems, HVAC, structural or stress analysis, manufacturing, automotive, aerospace, energy, robotics, or medical devices
• Demonstrated ownership of real engineering designs, analyses, components, or systems
• Experience with FEA, CFD, engineering drawings, specifications, testing, or production workflows
• Working proficiency with tools such as SolidWorks, CATIA, NX, Creo, AutoCAD, ANSYS, Abaqus, or MATLAB
• Familiarity with relevant standards such as ASME, ASTM, ISO, and GD&T per ASME Y14.5
• Clear progression toward senior or lead engineering responsibility
• Professional Engineer (PE) licensure is advantageous but not required
• Hands-on professional use of large language models and ability to distinguish strong reasoning from plausible technical errors
• Excellent written communication and structured technical-feedback skills
• Strong practical engineering judgement grounded in industry experience

Engagement Details

• Full-time engagement
• Remote — United States only
• Compensation: $60-$90/hour
• Expected commitment is 40 hours per week
• Initial engagement is approximately 2-3 months
• Work will involve mechanical-engineering review, reference-solution development, benchmark design, technical evaluation, and research collaboration
• Assignments may span mechanical design, thermal and fluid systems, structural analysis, manufacturing, controls, and related engineering domains
• Client-issued accounts and equipment may be provided for project work
• Strong real-world engineering ownership and practical design-review experience are central to this role
• Project scope, engineering domains, evaluation criteria, and technical priorities may evolve depending on research requirements
