Qualifications

• Bachelor’s or master’s degree in electrical engineering, physics, or a closely related field.
• 3+ years of experience in mixed signal electronics with RF/microwave measurements, high speed digital design, cryogenic electronics, or low noise analog signal paths.
• Experience with electronic measurement techniques, including signal integrity and power integrity evaluation, RF characterization, or low temperature test setups.
• Familiarity with PCB design or board bring up workflows, and exposure to hardware–firmware co design or FPGA/ASIC verification is a plus.
• Strong debugging and troubleshooting skills across test equipment, hardware interfaces, 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 integrating physics, computer science, data science, and engineering.
• Clear communication and documentation skills for reporting measurements, analysis results, and design recommendations.

Responsibilities

• Develop a deep understanding of cryogenic electronics and how control and readout signals drive qubit operations at low temperatures.
• Collaborate with scientists and engineers to define qubit control and readout requirements across mixed signal, RF/microwave, and high speed digital domains.
• Design, implement, and document 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 automated test procedures and lab automation workflows using modern instrumentation and scripting tools.
• Execute advanced measurements, including those involving spin qubits, to validate control system fidelity, noise performance, and overall robustness.
• Analyze data, perform root cause debug, and provide clear engineering recommendations for improving hardware performance.
• Work within focused technical teams to address high impact challenges in qubit control, cryogenic electronics reliability, and mixed signal system behavior.
