As an Electronics Development Engineer, you will contribute to the design, characterization, and validation of cryogenic mixed signal hardware used for qubit control and readout. This role involves low temperature measurements, RF/microwave techniques, high speed digital design, and hardware-firmware co design. Working closely with scientists and engineers, you will help develop custom electronics, automate test workflows, analyze complex data, and solve high impact challenges in qubit control performance.
Key Responsibilities:• Build an understanding of cryogenic electronics and how control and readout signals enable qubit operations at low temperatures
• Collaborate with scientists and engineers to help define qubit control and readout requirements across mixed signal, RF/microwave, and high-speed digital domains
• Assist in the design, implementation, and documentation of measurement techniques for characterizing qubit control electronics, including low temperature characterization, signal and power integrity, and RF/microwave performance
• Contribute to the design, specification, and validation of custom mixed signal and RF/microwave hardware, including PCB design, board bring up, and silicon bring up
• Support hardware-firmware co-design efforts, including FPGA and ASIC verification focused on timing, waveform fidelity, and interface correctness
• Develop and maintain automated test procedures and lab automation workflows using modern instrumentation and scripting tools
• Perform laboratory measurements, including those involving spin qubits, to evaluate control system fidelity, noise performance, and overall robustness
• Analyze test data, support root cause debugging, and provide engineering recommendations to improve hardware performance
• Work closely with cross-functional technical teams to address challenges in qubit control, cryogenic electronics reliability, and mixed signal system behavior
Required Qualifications:• Bachelor's degree in Electrical Engineering, Physics, or a closely related field
• 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
• Exposure to PCB design or board bring-up workflows; familiarity with hardware-firmware co-design or FPGA/ASIC verification is a plus
• 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 work collaboratively 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
Physical Requirements:• Must be able to climb ladders to use elevated test equipment
• Must be able to work safely in a laboratory environment and be on-site at least 4 days a week
