Inorganic Materials, Semiconductor & Superconductor Experts

Seoulstart; United States; Remote; USD 95,000 - 136,000; Full time

Job summary

Mercor is seeking experimental scientists and engineers across inorganic synthesis, characterization, superconductors, and semiconductors to support a frontier AI research lab.

This is hands-on, expert-level work: you'll apply deep, specialized knowledge to generate, structure, and evaluate the scientific data these models learn from - and your input will directly shape how advanced models reason about materials, devices, and processes.

Qualifications

• Hands-on experimental experience in inorganic synthesis, superconducting materials, or semiconductors.
• Strong materials or device characterization skills (XRD, SEM, TEM, spectroscopy, electrical/transport measurements).
• Experience with thin-film growth or device fabrication (MBE/epitaxy, MOCVD, CVD, sputtering, IBAD, etch, clean-room microfabrication).
• Advanced degree (PhD/MS) or equivalent hands-on experience in materials science, chemistry, physics, or a related engineering field.
• Clear written English and the ability to explain technical reasoning concisely.

Responsibilities

• Contribute domain expertise across synthesis, characterization, fabrication, and device physics to build high-quality training and evaluation data.
• Review and evaluate AI-generated scientific reasoning, catching errors and improving technical accuracy.
• Design and solve challenging, expert-level problems in your area of specialization.
• Rate and rank model outputs against defined scientific criteria, with clear written reasoning.
• Structure technical knowledge - experimental procedures, characterization results, process data - into well-organized, model-ready data.
• Deliver reliable, high-quality work within defined timelines.
