Remote PhD-Level Applied Physicist for AI Validation

Alignerr Corp.; Cambridge; Remote; GBP 55,000 - 165,000; Full time

Job summary

Alignerr Corp. is seeking PhD-level Applied Physicists for a remote, hourly-contract role focused on stress-testing AI models against physical laws. You’ll work asynchronously 10–40 hours per week, applying deep physics knowledge to craft rigorous problems and solutions that probe AI reasoning.

You’ll design multi-step problems across QM, E&M, classical mechanics, and thermodynamics, and provide disciplined feedback to guide researchers toward physically grounded AI systems.

Qualifications

• Holds a PhD (completed or near-completion) in Applied Physics, Physics, Engineering Physics, or a closely related field.
• Deep mastery across Classical Mechanics, Electrodynamics, Statistical Mechanics, and Quantum Mechanics.
• Exceptional analytical writing skills — explain complex derivations with clarity and rigor.
• Uncompromising precision in units, notation, dimensional analysis, and logical flow of a proof.
• Self-motivated and reliable when working independently and asynchronously.

Responsibilities

• Design Advanced Physics Problems — Craft PhD qualifying exam-level problems spanning quantum mechanics, electrodynamics, classical mechanics, and thermodynamics that demand multi-step logical reasoning and mathematical derivation
• Author Gold-Standard Solutions — Develop rigorous, step-by-step 'golden responses' where every physical constant, unit conversion, and logical step is unimpeachable
• Audit AI Reasoning — Evaluate AI-generated proofs and simulations for physical consistency, identifying where models hallucinate physics that violates first principles
• Provide Structured Feedback — Coach AI systems to reason correctly about boundary conditions, conservation laws, and real-world physical constraints
• Document Failure Modes — Systematically record how and where AI reasoning breaks down so that research teams can build better, more physically grounded models
