About Periodic Labs

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.

About the Role

As a Research Engineer, Semiconductor, you’ll own device-level validation of our materials work, taking novel thin-film stacks from deposition through patterned test vehicles to measure electrical performance. You’ll design and run short-loop experiments that demonstrate how materials and interfaces translate into device behavior, leveraging both internal and external lab resources. You’ll also contribute technical expertise to customer-facing engagements, and this role blends deep hands-on capability with the flexibility to work across teams and partners to solve hard materials problems.

What You’ll Do

• Design, fabricate, and characterize short-loop device test vehicles that demonstrate material and device performance against clear electrical targets.

• Build patterned devices end-to-end using photolithography, direct-write laser lithography, or e-beam lithography, integrated with deposition, etch, and metrology.

• Deposit thin-film stacks with engineered, complex interfaces using PVD, PLD, MBE, and ALD/CVD techniques.

• Perform electrical characterization on probe stations, and design and build custom measurement test benches where commercial tools fall short.

• Connect materials and interface properties to device outcomes, feeding insights back into film-stack and process development.

• Contribute technical expertise to customer-facing engagements, translating customer needs into experimental plans and results.

• Document experimental methodology, results, and learnings to feed both internal knowledge and AI training infrastructure.
  

You Will Thrive in This Role If You Have

• MS or PhD in Materials Science, Electrical Engineering, Physics, or a related field, plus relevant industry experience.

• Semiconductor industry experience in device development or process integration, background at an IDM, foundry, or memory manufacturer strongly preferred.

• Strong command of device physics and integration flows, with a track record of demonstrating device performance in short-loop test vehicles.

• Hands-on fabrication experience spanning lithography (photo, laser direct-write, or e-beam), thin-film deposition, etch, and metrology.

• A deep understanding of how materials selection and interface quality drive device performance.

• Proficiency in probe-station device measurement, plus the ability to architect and assemble custom electrical test setups.

• A strong condensed matter physics foundation, spintronics, magnetic materials, or quantum phenomena, is a plus.

• Working knowledge of emerging memory and logic device architectures is a plus.

• Startup-ready mindset: able to operate effectively in a fast-paced, ambiguous environment while implementing industry-standard best practices.
  

Mechanics

• Minimum education: Master’s degree with relevant experience

• Location: Menlo Park, CA

• Compensation: $220k - $300k + equity

• Visa sponsorship: Yes, we sponsor visas and will do everything we can to assist in this process with our legal support.
  

About Periodic Labs

Periodic Labs is building an autonomous laboratory for high-throughput materials discovery. Our work combines advanced chemistry, robotics, automation, AI, and materials science to accelerate scientific discovery while maintaining high standards of environmental, health, and process safety.

We are seeking a hands-on, highly organized EHS Technician to support day-to-day laboratory safety operations, hazardous waste management, chemical inventory, compliance activities, and laboratory readiness.

The Role

Working closely with the EHS Engineer, Facilities team, scientists, and technicians, you will help execute the laboratory’s EHS programs and keep the facility safe, compliant, organized, and inspection-ready.

Responsibilities

• Receive, inspect, label, inventory, and properly store incoming chemicals and compressed gases.

• Maintain accurate chemical inventory, SDS, hazard classification, and storage-location records in the laboratory inventory or LIMS system.

• Monitor chemical, compressed-gas, PPE, spill-response, and other EHS supply inventories and reorder as needed.

• Collect, label, package, move, and stage hazardous waste, including flammable solvents, corrosives, toxic and heavy-metal waste, pyrophoric and reactive waste, universal waste, electronic waste, sharps, used oil, vacuum pump oil, and contaminated PPE.

• Change satellite waste containers and support handling of larger containers, including 55-gallon drums, using approved procedures and equipment.

• Maintain satellite and central accumulation areas, ensuring containers are closed, compatible, properly labeled and dated, and managed within applicable storage limits.

• Coordinate hazardous waste pickups with disposal vendors and maintain manifests, profiles, disposal records, and related documentation.

• Perform routine laboratory safety inspections and compliance audits; document findings, assign or track corrective actions, and verify closure.

• Inspect and maintain spill kits, eyewash stations, safety showers, first aid supplies, fire extinguishers, oxygen monitors, gas detection equipment, PPE stations, emergency signage, and evacuation routes.

• Support gas detector bump testing, calibration coordination, maintenance records, and user training.

• Coordinate EHS onboarding, required safety training, respirator medical evaluations and fit testing, and other employee safety programs.

• Support regulatory, fire department, insurance, and internal inspections, including preparation of records and follow-up actions.

• Collect wastewater, process water, air, wipe, or other environmental samples and coordinate testing with external laboratories.

• Support chemical inventory reconciliation, CERS reporting, regulatory documentation, laboratory cleanouts, equipment moves, shutdowns, and decommissioning.

• Maintain strong laboratory housekeeping and proactively identify safety, storage, labeling, or compliance issues before they affect operations.

Qualifications

• Associate degree, technical certification, bachelor’s degree, or equivalent experience in EHS, chemistry, environmental science, occupational health, industrial technology, or a related field.

• At least 1–2 years of experience in laboratory operations, hazardous waste, chemical management, industrial EHS, semiconductor, biotechnology, manufacturing, or a related technical environment.

• Familiarity with laboratory chemical handling, hazard compatibility, and hazardous waste management.

• Strong organizational skills, attention to detail, and comfort maintaining accurate records.

• Able to safely move containers, handle supplies, and work throughout an active laboratory environment.

• Comfortable working independently while coordinating closely with scientists, engineers, vendors, and regulators.

Preferred Qualifications

• Experience with RCRA and California hazardous waste requirements, including DTSC, CUPA, or CERS.

• Experience with chemical inventory systems, environmental sampling, DOT hazardous-materials requirements, or TSDF coordination.

• HAZWOPER, CPR/First Aid, forklift, pallet jack, or related safety training.

• Experience supporting semiconductor, advanced materials, chemical, or research laboratories.

Mechanics

• Minimum education: Bachelor’s degree or similar experience
