Job descriptionMercor is seeking experimental scientists and engineers across inorganic synthesis, characterization, superconductors, and semiconductors (including advanced packaging) to support a frontier AI research lab building models for materials science and the physical sciences. 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. **Key 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. **You're a strong fit if you have:** - Hands-on experimental experience in one or more of: inorganic synthesis (solid-state, solution, solvothermal, sol-gel), superconducting materials, or semiconductors and advanced packaging. - 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) — a plus. - An 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. **Role Details:** - Type: Long-term, ongoing engagement - Engagement: Up to 40 hours/week (minimum 10) - Work arrangement: Remote (US-based)
