JOB VACANCY ANNOUNCEMENTThe National Astronomical Observatory of Japan (NAOJ) announces an Associate Professor
position for Development of Microwave Photonics and Digital Electronics.

1. Job Title: Associate Professor, one position
2. Division and Location: The Advanced Technology Center (ATC), NAOJ, Mitaka (Japan)
3. Area of Expertise: Applied Physics, Electrical/Electronic Engineering, and/or Radio
Astronomy
4. Job Description:
NAOJ has been playing a key role in the forefront of astronomical research worldwide,
as demonstrated in the construction and operation of large-scale astronomical facilities suchas Subaru Telescope, ALMA, and TMT (Thirty-Meter Telescope) as well as in thedevelopment of space-based instruments such as Hinode Satellite for solar observation, in theeffort to promote cutting-edge astronomy utilizing these advanced telescopes. ATC, theresearch center of NAOJ for advanced technology development to support these important
astronomical programs, has been producing successful results in the development of various
astronomical instruments.
Microwave photonics and digital electronics are key technologies for the upgrade ofexisting observatories and the design and construction of the next generation of radiotelescopes. In particular, the ALMA telescope, which is currently the most powerful on-ground
mm/sub-mm wave astronomical facility, will need to be progressively upgraded to continue
in this position towards the 2030s. The upgrade will happen in parallel to stable operations inthe second phase of the project, called ALMA2. The priorities and mid-term opportunities fordevelopment have been outlined in the ALMA Development Roadmap. These include themultiplication of the IF bandwidth and the improvement of the angular resolution. The firstwill pose challenges in the digitization of the IF signal, and related digital and photonic
electronics. For the latter, ALMA will have to increase its longer baselines (currently ~16 km)
to a final goal in between 30-100 km. The increase of the distance between the furthermost
antennas (e.g., > 1000 km) will pose challenges in the distribution of the photonic local
oscillator (LO) to the receivers in the different antennas, which is key to the success ofinterferometric observations.

We invite applications for an associate professor position at ATC. The successful
candidate for this position is expected to lead research and development efforts towards highstability photonic LO systems with time and frequency transfer capabilities, and backend anddata transport systems which can be applied to the upgrade of existing facilities, such as
ALMA, and other future telescopes.
The successful candidate will be a key figure in ATC, and a major player in international
collaborations such as the ALMA Project. The responsibilities of this position require acontinuous demonstration of leadership and outstanding performance in research activities,
and also to foster collaborations among NAOJ scientists and engineers to stimulate
productivity of science and development by making the best use of the strengths of NAOJ.
Fostering of young scientists, engineers and technicians including PhD students is also
required as part of the job responsibility.
As required qualifications for this position, applicants are expected to have a wide rangeof experience and skills in the field of radio astronomical instrumentation, and Time andFrequency transfer instrumentation, in particular in photonic and digital technologies, and tohave good Systems Engineering ability to strongly promote astronomical research anddevelopment keeping up with the demands of the times. Apart from advanced technical andscientific knowledge, the successful candidate must have good communication andnegotiation skills, and be able to work in English in large international teams. It is envisionedthat the successful candidate will raise the state of NAOJ’s presence in the world, as an overalloutcome of the above activities.
5. Terms of Appointment:
The successful candidate should be able to start as soon as reasonably possible after the job
offer has been accepted. The term of the contract will continue up to the end of the Japanese
academic year in which the faculty reaches NAOJ's mandatory retirement age of 65.
The probation period is 6 months.
6. Qualification:
Minimum Educational Requirement: Ph.D. or equivalent
