The selected candidate will join a multidisciplinary collaboration between IC designers and Quantum Scientist and Engineers. The candidate will be responsible for agreeing the specifications of the low-noise amplifier (LNA), contributing to the design, test it in isolation at room and deep cryogenic temperatures and demonstrate it operation alongside qubit devices.

• Characterising SiGe microwave low-noise cryogenic amplifiers (LNA) including S-parameters and noise temperature.
• Benchmarking LNAs in conjunction with silicon spin qubit devices.
• Contributing in the schematic design and simulation of next generation LNAs.
• Assisting in the commissioning and optimisation of cryogenic infrastructure, including dilution refrigerator setups, for quantum device testing.
• Writing and maintaining software tools for measurement automation and data analysis.
• Performing rigorous analysis of experimental results to support internal decision-making and technical manuscripts.

The successful candidate will have:

• PhD degree in electrical engineering, physics or related field.
• Proficiency with Python.
• Expertise in radiofrequency or microwave electronics.
• Ability to independently design and carry out complex experiments; perform data analysis and prepare technical reports and presentations.
• Strong collaborative approach with good communication and interpersonal skills.
• An inquisitive nature and logical approach to problem solving.

Additionally, the candidate should demonstrate experience in the following skills :

• Experimental experience with semiconductor quantum dots.
• Experience in the development of software interfaces to hardware/instrumentation.
