About AI Training Work
AI training is the human side of building artificial intelligence. Experts review and improve model responses so AI systems can produce more accurate, technically sound, and useful results.
In this project, your materials science and engineering judgment will help evaluate technical answers, identify weaknesses in AI reasoning, and provide feedback that informs future model improvements.
Work directly on the development of advanced AI capabilities
Apply real-world technical judgment to model-generated content
Help improve how AI reasons about specialized engineering problems
Complete work remotely with flexible scheduling
The Role
As a Materials Science Expert, you will evaluate and solve advanced materials science and engineering problems spanning materials selection, failure analysis, testing, and process development. You will review AI-generated technical responses for correctness, accuracy, and overall engineering quality.
The work combines theoretical analysis with practical engineering judgment. You will assess real-world materials selection and failure scenarios, explain your reasoning clearly, and contribute domain expertise that helps refine AI performance in materials science and engineering.
Role focus: Materials science and engineering AI evaluation
Level: Expert
Data formats and tasks include text evaluation, question answering, text generation, and RLHF
Project duration is expected to be under one month
Experts should be ready to begin shortly after onboarding
What You’ll Do
You will analyze technical content and provide precise feedback that meets project specifications. Strong written and verbal explanations are important because your evaluations will help communicate why an AI response is correct, incomplete, or technically flawed.
You will collaborate remotely with a distributed team of experts and project participants while documenting feedback consistently.
Evaluate AI-generated materials science and engineering responses
Assess technical correctness, accuracy, and engineering quality
Solve advanced problems involving materials selection, failure analysis, testing, and process development
Use microstructural analysis, fractography, mechanical testing, and thermodynamic or kinetic modeling
Analyze tensile, fatigue, hardness, thermal, and related test data
Apply root-cause analysis to materials failures and degradation mechanisms
Document feedback and provide clear written and verbal explanations
Contribute expertise that improves AI reasoning and model performance
Collaborate with a distributed remote team
Requirements
This role is intended for an experienced materials professional with strong technical judgment and the ability to communicate complex engineering concepts in professional English.
Bachelor’s degree or higher in Materials Science and Engineering, Metallurgy, or Mechanical Engineering or Chemical Engineering with a materials specialization
At least three years of hands-on experience in materials selection, failure analysis, testing, or process development
Expert knowledge of metals, polymers, ceramics, and composites
Strong understanding of microstructure-property relationships and degradation or failure mechanisms
Proven ability to analyze root-cause failures using fractography, metallography, and mechanical or thermal test data
Familiarity with ASTM, ASM, or ISO materials standards and process qualification requirements
Professional fluency in English with exceptional written and verbal communication skills
Availability for less than 20 hours per week
Ability to meet minimum weekly task submission requirements
Preferred Experience
Experience with materials characterization equipment or process development in a manufacturing environment is a plus. The project also strongly prefers evidence of rigor in authoring or evaluating challenging technical problems.
Experience with SEM, XRD, TEM, DSC, or TGA
Materials process development in a manufacturing environment
Service on an olympiad problem committee
Textbook problem-set or solutions-manual author credit
Item-writing experience for an NCEES or academic qualifying-exam committee
Service on an ASTM, ASM, or ISO materials standards committee
Top placement or team leadership in the TMS Materials Bowl, ASM International undergraduate design competition, or an MRS student award
Best-paper recognition at TMS Annual Meeting, MS&T, or MRS
Publication in Acta Materialia or Nature Materials
Acta Materialia Silver Medal, NSF CAREER, DOE Early Career, Sloan Fellowship, TMS Young Leader, or MRS Outstanding Young Investigator recognition
