Post-doctoral Researcher

to work on

SiGe-based cryogenic amplifiers for quantum computing

NanoGUNE is a research center devoted to conducting world-class nanoscience research for a competitive growth of the Basque Country. NanoGUNE is a member of the Basque Research and Technology Alliance (BRTA) and is recognized by the Spanish Research Agency as a María de Maeztu Unit of Excellence.

We are pleased to offer a Postdoctoral position in the field of Cryogenic electronics for Quantum Computing at nanoGUNE. The project is part of a collaborative effort between academic and industrial partners to develop low-noise, low-power cryogenic amplifiers for solid-state qubits. 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. 

The position is offered in the Quantum Hardware Group, led by Gonzalez Zalba, Fernando (f.gonzalez@nanogune.eu). More information can be found at https://www.nanogune.eu/en/research/groups/quantum-hardware.

The functions of the role are:

• 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.

We promote teamwork in a diverse and inclusive environment and welcome all kinds of applicants regardless of age, disability, gender, nationality, race, religion, or sexual orientation.

The position can start on 04/01/2027 and for a total length of up to 24 months. The contract will be funded by the Basque Government’s IKUR 2030 – Quantum Technologies research and innovation programme.

 Candidates should apply by completing the form below and attaching the following documents:

1. A complete CV 
2. A cover letter and at least two reference letters grouped in a single PDF file

The deadline for applications is 04/12/2026.
