In this exciting role, you will participate in the rapidly evolving quantum computing technologies by developing the FPGA-based control systems for a wide range of advanced qubit technologies, which may include superconducting circuits, neutral atoms and trapped ions platforms. You will participate and contribute to multiple projects and programs at LBNL, including the QuantISED Program, the Advanced Quantum Testbed (AQT) project and the Quantum System Accelerator (QSA) center.
The successful candidate must work collaboratively with the scientists, engineers, postdocs, technicians, and students, document and communicate results of work in peer-reviewed journal publications and oral presentation and participate in meetings, conferences, and reviews.
What You Will Do:
Work as a team member to develop and optimize the quantum bit control system (QubiC), including RF and electronics hardware design, printed circuit board design, testing and chassis to system design;
Conduct FPGA gateware design and verification for qubit control signal processing on different FPGA chips and low-level software driver and API development;
Participate in the quantum bit control system test and deployment and be responsible for implementation and supporting of the developed modules in the quantum bit control system;
Perform qubit characterization and gate optimization with the system under development;
Collaborate with other members to implement the state-of-the-art quantum control system;
Document and communicate the results of work in routine reports and oral presentations, including participation in meetings, reviews, conferences and publications in refereed journals.
What is Required:
Ph.D. in Electronic Engineering, Physics or related field plus postdoctoral research experience, or equivalent breadth and depth of experience;
2+ years of experimental experience with Superconducting quantum bit characterization; 4+ years of experimental experience with RF electronics design and testing with standard lab equipment; years of experience with FPGA RTL code development and verification and deployment; years of experience with high speed analog/digital electronics development.
Knowledge on architecting, design and implementing, analog, RF, digital and high-speed circuits;
Knowledge on board bring-up and complex systems debugging tools including network analyzer, oscilloscope, spectrum analyzer, chip scope etc.
Knowledge and experience of programming languages in Python, Verilog, SystemVerilog.
Ability to work independently and in collaboration with scientists, engineers, post-docs and technicians both within and outside Berkeley Lab;
Excellent analytical, organizational, and multi-tasking skills;
Availability to travel and present work at collaboration meetings, workshops and conferences, including international travel;
Excellent communication skills to effectively interact with all members, including other scientists, engineers, technicians, postdocs, and students;
Relevant publication record and demonstration of proficient written and oral presentation of scientific results.
Additional Desired Qualifications:
Experience with open source CAD programs e.g. KiCAD and FreeCAD;
Familiar with Xilinx FPGA development tool chain and the open source simulation & verification (e.g. Verilator, cocotb);
Experience on Beam Instrumentation Development System (BIDS) is preferred.
Comfortable in a Linux environment;
Knowledge of quantum information science from experimental and analytical experience is preferred.
This is a full time, 3 year, career-track term appointment that may be renewed to a maximum of five years and that may be converted to career based upon satisfactory job performance, continuing availability of funds, and ongoing operational needs.

About Lawrence Berkeley National Laboratory
In the world of science, Lawrence Berkeley National Laboratory (Berkeley Lab) is synonymous with excellence. Thirteen scientists associated with Berkeley Lab have won the Nobel Prize. Fifty-seven Lab scientists are members of the National Academy of Sciences (NAS), one of the highest honors for a scientist in the United States. Thirteen of our scientists have won the National Medal of Science, our nation's highest award for lifetime achievement in fields of scientific research. Eighteen of our engineers have been elected to the National Academy of Engineering, and three of our scientists have been elected into the Institute of Medicine. In addition, Berkeley Lab has trained thousands of university science and engineering students who are advancing technological innovations across the nation and around the world. Berkeley Lab is a member of the national laboratory system supported by the U.S. Department of Energy through its Office of Science. It is managed by the University of California (UC) and is charged with conducting unclassified research across a wide range of scientific disciplines. Located on a 200-acre site in the hills above the UC Berkeley campus that offers spectacular... views of the San Francisco Bay, Berkeley Lab employs approximately 4,200 scientists, engineers, support staff and students. Its budget for 2011 is $735 million, with an additional $101 million in funding from the American Recovery and Reinvestment Act, for a total of $836 million. A recent study estimates the Laboratory's overall economic impact through direct, indirect and induced spending on the nine counties that make up the San Francisco Bay Area to be nearly $700 million annually. The Lab was also responsible for creating 5,600 jobs locally and 12,000 nationally. The overall economic impact on the national economy is estimated at $1.6 billion a year. Technologies developed at Berkeley Lab have generated billions of dollars in revenues, and thousands of jobs. Savings as a result of Berkeley Lab developments in lighting and windows, and other energy-efficient technologies, have also been in the billions of dollars. Berkeley Lab was founded in 1931 by Ernest Orlando Lawrence, a UC Berkeley physicist who won the 1939 Nobel Prize in physics for his invention of the cyclotron, a circular particle accelerator that opened the door to high-energy physics. It was Lawrence's belief that scientific research is best done through teams of individuals with different fields of expertise, working together. His teamwork concept is a Berkeley Lab legacy that continues today.
