Principal Quantum Materials Engineer

## About the role * Define, implement, and refine MBE growth protocols for complex superconductor-semiconductor heterostructures * Achieve precise control over interfaces, composition, strain, and defect density that directly impact topological qubit performance * Drive materials improvements such as enhanced spin‑orbit coupling, reduced disorder, and reproducible interface quality * Design and execute principled, data driven experiments that couple growth conditions to structure, materials properties, and device outcomes * Own the growth → structure → properties → device feedback loop, ensuring materials advances translate into measurable qubit improvements * Provide technical judgment on growth tradeoffs that influence fabrication flows and process integration decisions * Design, build, upgrade, and maintain UHV MBE systems and in‑situ diagnostics (e.g., RHEED, spectroscopy) * Develop or integrate new diagnostics and tool capabilities to enable next-generation materials performance * Collaborate closely with nanofabrication, characterization, theory, and device teams to enable coherent, end-to-end process development * Communicate complex materials insights clearly across disciplines and help set technical direction where materials are the limiting factor * Operate effectively in an AI‑first R&D environment, using modern AI tools to accelerate discovery and optimization * Design or leverage AI agents/copilots to assist with experiment planning, log analysis, protocol templating, data interpretation, and knowledge retrieval * Ability to leverage AI tools to drive innovation and efficiency (e.g., performance modeling and analysis, research gathering, day-to-day task automation) * Ability to work in an "AI-first" environment using modern AI tools to accelerate discovery through hardware development ## Requirements * Doctorate in Physics, Engineering, or related field AND 3+ years experience in industry or in a research and development environment * PhD in Physics, Materials Science, Materials Engineering, or a related field AND 2+ years of experience in industry or advanced R&D Experience * Experience with semiconductor-superconductor hybrid materials, III‑V semiconductors, or related quantum‑relevant materials systems ## What we offer * As stated in the job posting, this position requires verification of citizenship or other protected status to meet legal requirements of the role.
