Overview
Applied Physics Specialist Jobs in Toronto, Ontario, Canada at Alignerr
Title: Applied Physics Specialist
Company: Alignerr
Location: Toronto, Ontario, Canada
Applied Physics Specialist (AI Training)
About The Role
What if your years of physics training could directly shape how AI understands the physical world — from quantum mechanics to thermodynamics? We're looking for PhD-level Applied Physicists to stress-test cutting-edge AI models, expose the gaps in their physical reasoning, and help ensure they respect the fundamental laws that govern our universe.
This is a fully remote, flexible contract role built for serious scientists. No prior AI experience needed — just deep domain expertise and the ability to think rigorously.
- Organization: Alignerr
- Type: Hourly Contract
- Location: Remote
- Commitment: 10–40 hours/week
What You'll Do
- Design PhD-level physics problems — craft complex, open-ended challenges requiring multi-step logical reasoning, mathematical derivation, and mastery of first principles across quantum mechanics, electromagnetism, thermodynamics, and more
- Author rigorous ground-truth solutions — produce precise, step-by-step "golden responses" with flawless handling of physical constants, units, and logical flow
- Audit AI-generated physics — evaluate model outputs for physical consistency, identifying where AI "hallucinates" results that violate conservation laws, boundary conditions, or established theory
- Refine AI reasoning — provide structured, expert feedback that helps AI models develop more accurate, physics-informed reasoning and better handle real-world constraints
- Document failure modes — systematically record where and how AI reasoning breaks down so these gaps can be systematically addressed
Who You Are
- Holds a PhD (completed or in final stages) in Applied Physics, Physics, Engineering Physics, or a closely related field
- Deep mastery of core physics pillars: Classical Mechanics, Electrodynamics, Statistical Mechanics, and Quantum Mechanics
- Exceptional analytical writer — able to explain complex derivations and physical phenomena in clear, structured English
- Uncompromising precision when it comes to units, scientific notation, dimensional analysis, and logical proof structure
- Self-motivated and comfortable working independently on challenging, open-ended problems
- No prior AI or machine learning experience required
Nice to Have
- Experience with scientific data annotation, dataset quality evaluation, or research benchmarking
- Proficiency with computational tools such as Python (NumPy/SciPy), MATLAB, or COMSOL
- Background in research-level problem design, such as qualifying exam authorship or peer review
Why Join Us
- Work at the frontier of AI development alongside world-leading research labs
- Fully remote and flexible — set your own hours and work from anywhere
- Freelance autonomy with access to genuinely interesting, intellectually demanding work
- Direct, meaningful impact on how AI models understand and reason about the physical world
- Exposure to cutting-edge large language models and the methods used to train them
- Potential for ongoing work and contract extension as new projects launch
