Job summary

Alice & Bob is developing the first universal, fault-tolerant quantum computer and seeks an RF Sub Systems Design & Characterization Intern in Aubervilliers, Île-de-France. You will support design, development, integration and validation of RF hardware to control qubits, under senior engineers, gaining hands-on experience with RF instruments and cryogenic components.

Work on three focus topics: cryogenic bias tee footprint reduction, RF readout optimization at room temp and cryogenic temps.

Qualifications

• Engineering or master's student specializing in microwave frequencies, RF electronics, telecommunications, applied physics, computing, instrumentation, or related fields.
• Solid understanding of RF systems, S-Parameters, and wave propagation.
• Experience with RF test equipment, signal characterization and analysis techniques (VNA, Spectrum Analyzer, and oscilloscope).
• Experience with RF CAD tools (HFSS, Keysight ADS,…)
• Familiarity with Python for RF data analysis and post-processing (NumPy, scikit-rf, matplotlib)
• Familiarity with basic lab and prototyping tools (multimeter, torque driver, power tools, soldering iron)
• Excellent communication skills in English, both written and oral. (English level B1/B2)

Responsibilities

• Integrate and test control electronics and instrumentation (RF, DC, etc.) with the help of senior engineers.
• Characterize, simulate, and design RF hardware at room temperature and cryogenic temperatures (bias tees, filters, …)
• Rapidly design and prototype sub-systems for Qubits control, considering the electromechanical integration inside of the cryostat or the racks
• Analyze and compare different RF component manufacturing technologies (substrates, processes, connectors, packaging, cables, etc.) in terms of performance, EMC, accessibility, and feasibility
• Assist with test bench setup, cabling, equipment maintenance and monitoring
• Perform lab measurements using RF bench equipment (VNAs and analyzers)
• Define, optimise, and automate the test programs needed to qualify or validate system hardware conformity
• Preparing complete, well-documented test plans and reports results
• Monitor instrument and component stock
• Collaborate with multidisciplinary teams to develop and integrate systems required to control quantum chip architectures
