Integrate and test control electronics and instrumentation (RF, DC, etc.) with support from senior engineers.
Characterize, simulate, and design RF hardware at room and cryogenic temperatures (bias tees, filters, etc.).
Rapidly design and prototype subsystems for qubit control, taking electromechanical integration inside the cryostat or rack systems into account.
Analyze and compare different RF component manufacturing technologies (substrates, processes, connectors, packaging, cables, etc.) with respect to performance, EMC, accessibility, and feasibility.
Assist with test bench setup, cabling, equipment maintenance, and monitoring.
Perform laboratory measurements using RF bench equipment (VNAs and spectrum analyzers).
Define, optimize, and automate the test programs required to qualify or validate hardware conformity.
Prepare complete, well-documented test plans and reports of results.
Monitor instrument and component inventory.
Collaborate with multidisciplinary teams to develop and integrate systems for controlling quantum chip architectures.

Solid understanding of RF systems, S-parameters, and wave propagation.
Experience with RF test equipment and signal characterization/analysis techniques (VNA, spectrum analyzer, oscilloscope).
Experience with RF CAD tools (ANSYS HFSS, Keysight ADS, etc.).
Familiarity with Python for RF data analysis and post-processing (NumPy, scikit-rf, matplotlib).
Experience using basic lab and prototyping tools (multimeter, torque driver, power tools, soldering iron).
Ability to work effectively in a team, with a strong innovative mindset.
Excellent written and verbal English communication skills (approx. B1/B2 level).
