About this position

The National Astronomical Observatory of Japan, part of the National Institutes of Natural Sciences, is seeking an ALMA Project Special Research Fellow to contribute to the ALMA 2 Project and technology research and development for future next-generation receivers.

The researcher will work on the design and performance evaluation of 385–500 GHz receivers, with particular emphasis on the design, verification, and improvement of onboard waveguide circuit components. The project also includes constructing and improving measurement systems for receivers and onboard components, as well as developing and verifying elemental technologies for next-generation receiver systems.

The position is based in the ALMA Project at the National Astronomical Observatory of Japan in Mitaka, Tokyo. The researcher will collaborate with the receiver team and development manager in a specialist radio astronomy environment focused on high-sensitivity receivers, microwave and millimeter-wave components, waveguide technology, and advanced measurement systems.

The appointment is a fixed-term research role beginning in April 2027, with the possibility of renewal subject to project needs, performance, workload, and organizational conditions.

Funding details

This is a salaried fixed-term research position with an annual income of approximately 4–5 million yen; the base annual salary is approximately 4.2 million yen, or about 350,000 yen per month, with the final amount determined by duties, performance, and experience.
