Data & AIScienceFullTime
We’re an AI and physical sciences company building state-of-the-art models to accelerate breakthroughs across materials, energy, and beyond. Backed by world-class investors and growing rapidly, we operate at the pace the frontier requires. Our team brings deep expertise, genuine ownership, and an insatiable drive to push the boundaries of what’s scientifically possible.
Join a world-class team of scientists and engineers pushing the boundaries of materials research in a groundbreaking lab where AI and automation unlock discoveries at unprecedented speed and scale. As a Research Scientist within the Periodic Labs experimental effort, you bring AI predictions into reality through physics and measurement science. In this role, you will both develop new material characterization approaches and be part of the team developing autonomous discovery loops.
This is a senior, hands-on role. You will own the design and execution of high-fidelity property measurements, drive the development of high-throughput characterization schemes, and collaborate closely with AI, automation, and materials science teams to build feedback loops that accelerate discovery. You will set the standard for measurement quality and data integrity across the lab.
Develop and perform high-fidelity thermodynamic, transport, and spectroscopic measurements of materials, including electronic, magnetic, and thermal properties
Design and implement rapid property measurement schemes to scale up the material characterization process and feed AI-guided discovery pipelines
In collaboration with the AI team, implement automated data analysis and reasoning pipelines for screened materials; contribute to feedback loop design between measurement and prediction
In collaboration with the engineering team, develop autonomous systems for property characterization leveraging robotics and programmable instrumentation
Evaluate, procure, and commission new instrumentation; develop custom measurement setups where commercial solutions are insufficient
Define and enforce data standards, metadata schemas, and documentation practices to ensure measurement outputs are reproducible and reusable
Uphold and contribute to lab safety standards, particularly around cryogenic systems, high-field magnets, and hazardous materials
PhD in Physics, Materials Science, or related field, with 5+ years of hands-on experience in physical property characterization
Deep, demonstrated expertise in electronic and magnetic property measurements, including resistivity, Hall effect, magnetometry, and heat capacity
Strong background in cryogenic measurements and low-noise techniques, including lock-in methods, shielding/grounding, and precision instrumentation
Strong track record of highly impactful research demonstrated by publications in top-tier journals and/or inventions, and recognized leadership in the field
Proficiency with data analysis (e.g., Python/Jupyter, familiarity with instrument SDKs a plus) and disciplined data management practices
Excellent scientific writing, cross-disciplinary collaboration, and strong ownership of experiment quality
Ability to communicate measurement requirements and findings clearly to AI, engineering, and materials science collaborators
Experience with automation of physical property measurement platforms (e.g., PPMS, MPMS, custom rigs)
Experience with the computational prediction and experimental characterization design loop
Experience with spectroscopic characterization techniques such as ARPES, neutron scattering, or optical spectroscopy
Experience with lab buildout, instrument commissioning, and process safety
Experience handling and managing data at scale, including LIMS or similar data infrastructure
Previous work at national laboratories or large-scale user facilities
Minimum education: Bachelor’s degree or similar experience
Employment type: Full-time, 12-month term
Location: Our lab is located in Menlo Park and we prefer folks to be located in Menlo Park or San Francisco but can be flexible based on role
Compensation: $225,000-325,000 + equity
Visa sponsorship: Yes, we sponsor visas.
We’re building a team of the world’s best — the scientists, engineers, and problem-solvers who don’t just follow the frontier, they define it. If you’re driven to bring AI to life in the physical world and make discoveries that have never been made before, you belong here.
