You will build realistic scenarios with supporting data, explain the reasoning another scientist should follow, and review work for technical accuracy. This is that work, done remotely around your schedule.\nWhat you'll do\nDesign hard problems across structure and properties, processing, characterization, failure analysis, and computational materials\nTurn real materials problems into scenarios with constraints and supporting data that test more than textbook recall\nWrite the sound analysis and make the reasoning clear enough for an independent scientist to check\nCreate objective grading criteria and review other contributors' problems for sound methods and clear grading\nWhy this is worth your time\nGet paid $85-$185 an hour\nApply deep materials science expertise to problems involving metals, ceramics, polymers, composites, semiconductors, thin films, or related areas\nWork directly on AI training tasks by writing solutions, defining correctness, and evaluating technical work\nFully remote and flexible, no fixed shifts, no commute\nWho this is for\nA master's or PhD in materials science, or in a related discipline such as metallurgy, ceramics, polymer science, or condensed matter physics\nPrincipal, staff, or fellow-level work in industrial research or government research labs, or a faculty appointment at a leading university\nDeep expertise in a materials science specialty, with hands-on ownership of the work\nSound engineering and scientific judgment when reading constraints and weighing possible solutions\nCan justify a result clearly enough for another scientist to verify independently\nProfessional fluency in English\nPublications, patents, or technical leadership experience are helpful\nNo AI experience needed. AI or large-language-model evaluation experience is a helpful extra, not a requirement.\nPay and details\n$85-$185 hourly under an independent-contractor arrangement\nPart-time, fully flexible schedule; fully remote, United States\nHow to apply\n1. Apply on OpenTrain with your resume.\n2. Complete the application on the hiring platform.\n3. If shortlisted, take a short AI interview.\nReady to create materials science problems, write verified analyses, and review the technical work used to evaluate AI? Apply today.\nAbout OpenTrain AI\nOpenTrain AI connects experienced professionals with paid, part-time AI training work: shaping and improving the AI systems that companies are building right now.","description_format":"text","description_chars":2790,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":["Flexible schedule"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Materials Science & Nanotechnology","Artificial Intelligence","LLM & Generative AI","Reinforcement Learning"],"lifecycle":[{"event":"open","at":"2026-11-01T09:04:15Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":37,"reasons":["seen:1","velocity","win:early"],"computed_at":"2026-11-03T05:54:40Z"},"pay":{"stated_usd_annual":370000,"is_top_pay":true},"html_url":"https://alion.io/job/opentrain-ai-materials-science-expert-technical-evaluation","json_url":"https://alion.io/job/opentrain-ai-materials-science-expert-technical-evaluation.json","meta":{"generated_at":"2026-11-04T03:11:28Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":4928,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-05T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":4457061},"rest":"https://alion.io/mcp/rest/get_company?id=4457061"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fopentrain-ai-materials-science-expert-technical-evaluation"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fopentrain-ai-materials-science-expert-technical-evaluation"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fopentrain-ai-materials-science-expert-technical-evaluation"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/opentrain-ai-materials-science-expert-technical-evaluation\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fopentrain-ai-materials-science-expert-technical-evaluation"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3584954}},{"tool":"search_jobs","arguments":{"company":"opentrain.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3584954},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
