About AI Training Work

AI training is the human side of building artificial intelligence. Specialists provide examples, solve challenging questions, and review model-generated responses so AI systems become more accurate, useful, and reliable.

In this role, your engineering judgment will help evaluate whether AI-generated technical content is correct, complete, clearly explained, practical to manufacture, reliable in use, and aligned with relevant industry standards.

• Work directly on cutting-edge AI development
• Apply real-world technical expertise to model evaluation
• Improve the quality and usefulness of AI-generated engineering content

The Role

OpenTrain is hiring a Mechanical Engineering Subject Matter Expert to support AI training through advanced problem solving and technical content evaluation. You will work across engineering mechanics, thermodynamics, fluid mechanics, heat transfer, vibrations, and manufacturing.

The work requires practical engineering judgment, careful analysis, and the ability to explain technical decisions in detailed written feedback. The role is listed as entry level, while the project requires substantial knowledge across core mechanical engineering disciplines.

• Role focus: Mechanical Engineering Review
• Data type: Text
• Task types: Question answering and evaluation or rating
• Engagement: Part-time contractor
• Workload: 20+ hours per week
• Location: Worldwide

What You’ll Do

You will analyze complex mechanical engineering scenarios and assess AI-generated answers against real-world engineering expectations. Your feedback will help identify errors, strengthen explanations, and improve the usefulness of model outputs.

The role combines technical review with detailed communication. You will need to explain your reasoning clearly and provide practical recommendations for design and analysis decisions.

• Analyze complex problems in engineering mechanics, thermodynamics, fluid mechanics, heat transfer, vibrations, and manufacturing.
• Review AI-generated engineering content for accuracy, clarity, completeness, and feasibility.
• Evaluate proposed solutions for manufacturability, reliability, and industry standard compliance.
• Write detailed rationales supporting engineering decisions and recommendations.
• Apply practical judgment to real-world design and analysis scenarios.
• Collaborate remotely and communicate clearly with a multidisciplinary team.

Requirements

This opportunity is intended for candidates with broad mechanical engineering knowledge and the ability to assess technical work rigorously. Strong English communication is essential because the role involves detailed written and verbal feedback.

• Deep knowledge of mechanical engineering fundamentals across mechanics, thermodynamics, fluid mechanics, heat transfer, vibrations, and manufacturing.
• Ability to evaluate AI-generated technical answers for accuracy, clarity, completeness, and feasibility.
• Experience applying manufacturability and reliability judgment to design scenarios.
• Strong written and verbal English communication skills.
• Background in mechanical design, product development, analysis, or research and development.
• Comfort collaborating remotely with multidisciplinary teams.
• Experience delivering mechanical products or systems through production is a plus.

Who Should Apply

This role may suit mechanical engineers and technical specialists who enjoy solving complex problems, reviewing explanations, and translating engineering judgment into clear written guidance. It is especially relevant to people with experience in design, product development, analysis, R&D, or production-oriented engineering work.

You should be comfortable examining both the technical correctness and practical implications of a proposed solution, including whether it can be manufactured, relied upon, and applied appropriately.

• Mechanical engineering specialists with broad cross-disciplinary knowledge
• Professionals experienced in design, product development, analysis, or R&D
• Engineers who can provide precise, constructive technical feedback
• Candidates with strong English communication skills
