Applied Physics

Alignerr; 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

Job description

About The Role

What if your expertise in quantum mechanics, electrodynamics, and thermodynamics could directly shape how AI understands the physical world? We're looking for PhD-level Applied Physicists to stress-test cutting-edge AI models — exposing the gaps in their physical reasoning and helping ensure they never violate the fundamental laws of the universe.

Applied Physics (AI Training)

What if your expertise in quantum mechanics, electrodynamics, and thermodynamics could directly shape how AI understands the physical world? We're looking for PhD-level Applied Physicists to stress-test cutting-edge AI models — exposing the gaps in their physical reasoning and helping ensure they never violate the fundamental laws of the universe.

This is a fully remote, flexible contract role built for researchers and academics who want to do meaningful, intellectually stimulating work on their own schedule. No prior AI experience required — just deep domain mastery and a rigorous, analytical mind.

• Organization: Alignerr
• Type: Hourly Contract
• Location: Remote
• Commitment: 10-40 hours/week
  

What You’ll Do

• 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
  

Who You Are

• Holds a PhD (completed or near-completion) in Applied Physics, Physics, Engineering Physics, or a closely related field
• Deep mastery across the core pillars: Classical Mechanics, Electrodynamics, Statistical Mechanics, and Quantum Mechanics
• Exceptional analytical writing skills — you can explain a complex derivation in clear, structured prose without losing rigor
• Uncompromising precision when it comes to units, scientific notation, dimensional analysis, and the logical flow of a proof
• Self-motivated and reliable when working independently and asynchronously
• No prior AI or data annotation experience required
  

Nice to Have

• Experience with data annotation, scientific dataset evaluation, or quality assurance for research outputs
• Proficiency with computational tools such as MATLAB, COMSOL, Python (NumPy/SciPy), or similar
• Background in experimental or computational physics research
• Familiarity with AI or machine learning concepts as an end user or researcher
  

Why Join Us

• Work on high-impact AI projects in collaboration with the world's leading AI research labs
• Fully remote and flexible — work when and where it suits you, on your own schedule
• Freelance autonomy with the intellectual depth of meaningful, research-level work
• Gain direct exposure to how frontier large language models are trained and evaluated
• Contribute to AI development that could shape how technology understands the physical world for decades to come
• Potential for ongoing work and contract extension as new projects launch
