Principal Quantum Hardware Engineer

Experimental Execution: Plan and execute cryogenic quantum hardware experiments, including device bring-up, characterization, calibration, data analysis, and iterative troubleshooting of low-temperature measurement systems. Cryogenic Systems: Operate, maintain, and improve dilution refrigerators systems, including cryogenic wiring, vacuum systems, thermal anchoring, filtering, shielding, and related infrastructure required for reliable low-temperature measurements. Instrumentation & Measurement: Configure and debug RF/microwave control and readout chains, DC electronics, data acquisition systems, signal generators, digitizers, amplifiers, and custom test setups used in quantum device experiments. Automation & Data: Develop scripts, procedures, and analysis workflows for experiment automation, data collection, system monitoring, and reproducible measurement execution. Hardware Integration: Partner with scientists, engineers, vendors, and systems architects to integrate devices, packages, interconnects, cryogenic components, control hardware, and software into stable experimental platforms. Lab Readiness, Safety & Compliance: Support safe operation of cryogenic, electrical, vacuum, and export-controlled lab environments; contribute to procedures, documentation, change control, and readiness for internal and external milestones. Doctorate in Physics, Engineering, or related field AND 3+ years experience in industry or in a research and development environment OR Master's Degree in Physics, Engineering, or related field AND 6+ years experience in industry or in a research and development environment OR Bachelor's Degree in Physics, Engineering, or related field AND 8+ years experience in industry or in a research and development environment OR equivalent experience. These requirements include, but are not limited to the following specialized security screenings: Citizenship & Citizenship Verification: This role will require access to information that is controlled for export under export control regulations, potentially under the U.S. International Traffic in Arms Regulations (ITAR) or Export Administration Regulations (EAR), the EU Dual Use Regulation, and/or other export control regulations. As a condition of employment, the successful candidate will be required to provide either proof of their country of citizenship or proof of their U.S. permanent residency or other protected status (e.g., under 8 U.S.C. § 1324b(a)(3)) for assessment of eligibility to access the export-controlled information. To meet this legal requirement, and as a condition of employment, the successful candidate's citizenship will be verified with a valid passport. Lawful permanent residents, refugees, and asylees may verify status using other documents, where applicable. Ability to work in an “AI-first” environment using modern AI tools to accelerate discovery through both hardware and software development. Ability to use and help build AI agents/copilots that assist with experimental workflows — e.g., instrument configuration, maintenance tracking, safety/readiness checklists, protocol templating, logbook summarization, and knowledge retrieval from instrument manuals, install guides, and configuration documentation. Experience designing, building, operating, or troubleshooting experimental systems involving cryogenic, vacuum, RF/microwave, or low-noise measurement infrastructure. Experience standing up, operating, or improving experimental quantum, cryogenic, condensed matter, superconducting device, semiconductor, or related low-temperature measurement laboratories. Deep hands-on experience with cryogenic systems, dilution refrigerators, vacuum systems, RF/microwave wiring and I/O, filtering, shielding, low-noise electronics, and related low-temperature measurement infrastructure. Experience with export‑controlled or government‑program environments (ITAR/EAR), including compliance, configuration management, and document/records control. Experience integrating complex experimental hardware systems, coordinating with vendors, and managing components, spares, calibration, and logistics for cryogenic or precision measurement platforms. Proficient background in Python or similar scripting languages, Linux-based systems, experiment control, lab automation, data acquisition, and analysis of experimental measurement data. Excellent organizational, verbal, and written communication skills, and the judgment to set the operational foundation for a new facility. Ability to partner across science, hardware engineering, systems architecture, program management, facilities, vendors, and government/ecosystem stakeholders in a fast-paced, interdisciplinary experimental environment.
