About The Position

HRL Laboratories’ Qubit Systems Laboratory is seeking an Electronics Development Engineer to contribute to the design, characterization, and validation of cryogenic mixed-signal hardware for qubit control and readout. The work involves low-temperature measurements, RF/microwave techniques, high-speed digital design, and hardware–firmware co-design. The engineer will collaborate with scientists and engineers to develop custom electronics, automate test workflows, analyze data, and address challenges in qubit control performance. The role includes characterizing control electronics and performing laboratory measurements, including measurements involving spin qubits. The engineer will support custom mixed-signal and RF/microwave hardware development, FPGA and ASIC verification, automated testing, data analysis, and debugging. The position requires working safely in a laboratory and being onsite at least four days per week. Applicants must have US Person Status.

Requirements

Bachelor's degree in Electrical Engineering, Physics, or a closely related field.
At least 2 years of industry, research, or graduate-level experience in mixed-signal electronics, with exposure to RF/microwave measurements, high-speed digital design, cryogenic electronics, or low-noise analog signal paths.
Familiarity with electronic measurement techniques, including signal-integrity and power-integrity evaluation, RF characterization, or low-temperature test setups.
Demonstrated troubleshooting and debugging skills across hardware, test equipment, and measurement environments.
Experience with automated testing, lab automation tools, or data analysis using scripting languages such as Python or MATLAB.
Ability to collaborate with teams across physics, computer science, data science, and engineering disciplines.
Strong written and verbal communication skills for documenting measurements, analysis results, and engineering recommendations.
Must be able to climb ladders to use elevated test equipment.
Must be able to work safely in a laboratory environment and be onsite at least 4 days a week.
US Person Status.
