Quantum Engineering Postdoctoral Fellow

Overview

Berkeley Lab's Applied Mathematics Computational Research Division (AMCR) has an opening in the Quantum Information Science and Technology Group (QuIST) for a Quantum Engineering Postdoctoral Fellow under the Advanced Quantum Testbed (AQT) and Quantum System Accelerator (QSA) programs. The position focuses on materials and circuit electric field engineering to study material–performance causality of superconducting qubits, including electromagnetic design optimization and development of new metrology and fabrication techniques.

The fellow will have access to the state-of-the-art superconducting circuit fabrication facility, quantum measurement lab, and advanced material characterization tools at Lawrence Berkeley National Laboratory and will be part of the team developing and fabricating a multiqubit, multilayer quantum processor unit (QPU) for full-stack superconducting QPU research.

• Perform electromagnetic simulation of qubit circuits with novel designs to achieve high coherence qubits.
• Develop cleanroom metrology for superconducting qubit devices, including CMOS in-line metrology, in the lab and in collaboration with industrial partners.
• Fabrication process development and optimization to improve device materials and characterize qubit device performance.
• Fabrication of multiqubit, multilayer quantum processor developed at Berkeley Lab.
• Present and publish experimental results in internal and external meetings and journals.
• Support and lead collaboration projects with quantum computing industrial partners.

• Mentoring graduate students.
• Support or lead writing including program reports, grants, and papers.

• Ph.D. degree in Physics, Applied Physics, Electrical Engineering, Material Science, or a related field.
• Experience in cleanroom/nanofabrication processes with hands-on knowledge of cleanroom metrology for device performance/yield characterization.
• Experience in one or more of the following areas:
  • Solid state quantum computing platforms (e.g., superconducting qubits, spin qubits, semiconductor nanowire/topological qubits, rare-earth qubits, nanophotonic).
  • Microwave circuit design and simulation (EM solvers, network analysis).
  • Complex-structure device fabrication (CMOS multilayer devices, flip-chip devices, microwave air bridges, RF circuit devices).
• Relevant publication record and proficiency in written and verbal communication of scientific results.
• Ability to work effectively in a collaborative environment.
• Ability to mentor and direct the work of students.
• Willingness to travel occasionally to collaborators' sites and conferences.

• Experience in superconducting qubit design, fabrication, and measurement, including surface participation simulation and material loss tangent.
• Familiarity with material–device causality, linking film microstructure and surface chemistry to device physics and performance.
• Experience with surface treatment and surface metrology/measurement.

• We offer a total rewards package including comprehensive health and retirement benefits, tuition assistance, and a supportive culture.
• Vacation, sick time, and an annual Winter Holiday Shutdown; parental bonding leave and additional perks are available.

• Appointment type:
  Full-time, 2-year postdoctoral appointment with possible renewal based on performance, funding, and needs. Less than 3 years of paid postdoctoral experience required. Salary determined by postdoctoral steps.
• Application consideration begins June 15, 2026; rolling basis until the posting is removed.
• Work modality:
  On-site, hybrid, or full-time telework. Primary location is Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA. Work must be performed within the United States. Real  acceptable identification required to access sites.
• Background check required; convictions will be evaluated for relevance to responsibilities. A conviction history will not automatically disqualify an applicant.
• This position is represented by a union for collective bargaining purposes.
