About AI Training Work

AI training is the human side of building artificial intelligence. Specialists create, review, and evaluate examples that help AI systems produce more accurate and useful results. In technical projects, this can include assessing engineering models, calculations, simulations, schematics, and written problem statements.

Your engineering judgment will help evaluate whether technical assets are correct, complete, reproducible, and supported by clear assumptions. This work offers a way to apply professional expertise to cutting-edge AI development from a remote setting.

• Contribute expert judgment to the development of AI systems
• Work with technical assets such as models, simulations, calculations, and schematics
• Apply engineering experience to evaluation and documentation tasks

The Role

OpenTrain is seeking a CAD and Simulation Engineer for AI Training to support work involving aerospace, mechanical, and electrical engineering. You will create and review CAD models, simulation models, calculations, schematics, engineering problem statements, and related technical assets.

The role requires clear, reproducible engineering solutions and careful technical judgment. You will translate technical requirements into structured simulation workflows, evaluate results, and communicate assumptions and decisions clearly.

• Focus area: aerospace electrical simulation review
• Languages: English
• Worldwide remote eligibility

What You'll Do

You will develop CAD models and perform simulation and analysis for aerospace, mechanical, and electrical components. You will define the technical structure needed to make engineering work reproducible and assess submissions for correctness and completeness.

The work includes collaboration with engineering teams, analytical validation, design optimization, and thorough documentation of methodologies, processes, outcomes, and engineering decisions.

• Create and review CAD models for engineering components
• Develop simulation models and workflows from technical requirements
• Define inputs, assumptions, constraints, and operating conditions
• Specify output metrics and acceptance criteria
• Validate simulation results through analytical checks
• Optimize designs using simulation findings
• Review engineering submissions for technical correctness and completeness
• Document methodologies, outcomes, processes, and engineering decisions
• Perform design trade-off analysis and communicate assumptions clearly

Requirements

This assignment is intended for an experienced CAD engineering and simulation professional with strong aerospace, mechanical, or electrical engineering fundamentals. Practical experience with modeling, simulation, or design projects is required.

You should also bring professional proficiency with relevant engineering tools and the ability to apply sound analytical judgment when reviewing technical work.

• At least 10 years of experience in CAD engineering and simulation-focused organizations
• Ability to develop reproducible CAD models, simulation workflows, calculations, schematics, and technical problem statements
• Strong fundamentals in aerospace, mechanical, or electrical engineering
• Practical expertise in at least one electrical specialization, such as circuit analysis, power systems, electrical machines, power electronics, control systems, protection, grounding, instrumentation, or electronics design
• Professional proficiency with MATLAB, Python, KiCad, ANSYS, CATIA, SolidWorks, COMSOL, or comparable platforms
• Ability to define assumptions and acceptance criteria and validate results analytically
• Strong technical documentation, peer review, problem-solving, and communication skills

Schedule and Engagement

This is a remote contractor assignment lasting 8 weeks. The expected commitment is 20 to 40 hours per week, with at least 4 hours of overlap during Pacific Time.

Compensation is not disclosed for this role.

• Engagement type: Contractor and part-time
• Expected availability: 20 to 40 hours per week
• Required overlap: At least 4 hours in Pacific Time
• Duration: 8 weeks
• Work location: Remote and worldwide
