Chemical Engineer AI Evaluation Specialist

About OpenTrain

OpenTrain AI is the hiring and contracting organization for this role. OpenTrain helps people build careers in AI training and data labeling, where expert contributors teach and evaluate the systems shaping modern artificial intelligence.

As an OpenTrain contractor, you can create a professional AI training profile, apply to relevant projects, and build a durable portfolio of specialized evaluation work.

• Remote contract opportunity
• Flexible, project-based workload
• Hourly compensation of $40-$100 USD
• Part-time schedule requiring 20+ hours per week during active project periods

About AI Training Work

AI training is the human side of building artificial intelligence. Specialists review model outputs, write and refine prompts, rank responses, and provide detailed feedback so AI systems become more accurate, reliable, clear, and safe.

In this role, your chemical engineering expertise will help evaluate whether AI-generated technical content reflects sound calculations, process reasoning, professional judgment, and appropriate safety considerations.

• Help shape how advanced AI explains technical concepts
• Evaluate model responses against real-world engineering standards
• Perform cutting-edge work remotely with a flexible project structure

The Role

OpenTrain is seeking a Chemical Engineer AI Evaluation Specialist to review advanced AI-generated chemical engineering content. You will assess technical accuracy, logical soundness, completeness, clarity, assumptions, unit consistency, safety considerations, and process reasoning.

The work spans material and energy balances, thermodynamics, unit operations, separations, process control, scale-up, and plant troubleshooting. You will also refine prompts, responses, explanations, and step-by-step engineering solutions so they better reflect sound chemical engineering judgment.

• Intermediate experience level
• English-language work
• Remote availability in Bangladesh, Bhutan, Brazil, Cambodia, Germany, India, Indonesia, Malaysia, Nepal, Pakistan, Singapore, Sri Lanka, Thailand, the Philippines, the United States, Timor-Leste, and Vietnam
• Contractor and part-time engagement

What You'll Do

You will challenge AI systems with realistic calculations, scenarios, and process-informed reasoning tasks, then document precise feedback on the quality of their outputs. Your reviews will help improve both technical performance and responsible communication.

• Evaluate AI-generated responses for technical accuracy and completeness across chemical engineering topics
• Review and refine prompts, model responses, explanations, and engineering solutions
• Identify factual errors, flawed assumptions, missing constraints, unsafe recommendations, unit mistakes, consistency errors, and incomplete reasoning
• Assess balances, phase behavior, thermodynamic property use, unit operations, separations logic, and process control
• Evaluate process safety, scale-up, operability, and troubleshooting of plant scenarios
• Help AI explain assumptions, limitations, calculations, and professional judgment clearly
• Recognize when escalation to a licensed engineer or site expert is appropriate

Required Qualifications

This role requires substantial professional chemical engineering experience and the ability to critique technical content with precision. Deep chemical engineering expertise is the primary requirement; prior AI evaluation experience is valuable but not essential.

• At least 4 years of professional chemical engineering experience
• Hands-on experience in process design, plant or operations engineering, process safety, scale-up, manufacturing, utilities, EHS, quality, R&D, or controls and automation interfaces
• Bachelor's degree in Chemical Engineering or a closely related field
• Strong knowledge of material and energy balances, thermodynamics, fluid mechanics, heat and mass transfer, reaction engineering, separations, unit operations, and process control
• Comfort with engineering calculations, assumptions, constraints, uncertainty, safety factors, and defensible reasoning
• Ability to identify flawed assumptions, missing constraints, and unsafe technical recommendations

Preferred Experience

Advanced credentials and familiarity with standard chemical engineering documentation and process tools will strengthen your ability to evaluate complex model outputs.

• Master's degree, doctorate, Professional Engineer license, or Chartered status strongly preferred
• Prior AI data training, annotation, red-teaming, or evaluation of AI-generated technical content
• Familiarity with PFDs and P&IDs
• Experience with Aspen Plus, HYSYS, or CHEMCAD
• Knowledge of process datasheets, PSM documentation, HAZOP, LOPA, or SOPs

Who Should Apply

This opportunity is designed for chemical engineering specialists who are comfortable evaluating assumptions and edge cases, checking technical reasoning, and communicating precise written feedback. It may suit professionals from process design, plant operations, process safety, scale-up, manufacturing, utilities, EHS, quality, R&D, or controls-related environments.

• Chemical engineers with strong process and technical judgment
• Professionals who can assess safety, uncertainty, constraints, and unit consistency
• Experts who enjoy critiquing explanations and improving step-by-step solutions
• Candidates interested in applying chemical engineering expertise to AI training

Compensation and Schedule

This is a remote contract role with hourly pay ranging from $40 to $100 USD. The workload is flexible and project-based, with qualified specialists expected to maintain steady availability for review work during active project periods.

• $40-$100 USD per hour
• 20+ hours per week
• Flexible, part-time project workload
• Remote contract engagement
