Principal Quantum Materials Engineer

Advanced Heterostructure Growth: 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. Materials-Device Feedback & Experimentation: 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. Tooling & Diagnostics Leadership: 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; 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.
