Principal Quantum Materials Engineer

About the role

Advanced Heterostructure Growth: Define, implement, and refine thin film deposition protocols for complex superconductor-semiconductor heterostructures and semiconductor-dielectric interfaces; Achieve precise control over interfaces, composition, strain, band offsets, and defect density.

Materials-Device Feedback & Experimentation: Design and execute principled, data driven experiments that couple thin film deposition conditions to structure, materials properties, and device outcomes; ensure materials advances translate into measurable qubit improvements; provide technical judgment on materials tradeoffs that influence fabrication flows and process integration decisions.

Tooling & Diagnostics Leadership: Design, build, upgrade, and maintain thin film deposition systems and in‑situ diagnostics (e.g., RHEED, spectroscopy); develop or integrate new diagnostics and tool capabilities to enable next‑generation materials performance; Cross Functional Technical Leadership: 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.

AI Accelerated Materials Development: 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.
