Offer Description

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.

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