Seeking a Research Scientist or a Postdoctoral Researcher (25-1697) Part-time

Research Scientist Or Postdoctoral Researcher

Quantum Energy Conversion RIKEN ECL Research Team RIKEN Pioneering Research Institute (RIKEN ECL Team Leader: Miyabi Imai)

The structure and properties (functions) of materials are closely related, yet investigating both aspects at the atomic scale has remained a significant challenge. Our laboratory advances atomic-scale spectroscopy based on photon scanning tunneling microscopy (Photon-STM) to directly correlate the local structure and energy conversion properties of single molecules. Furthermore, we strive to develop novel energy conversion functionalities by precisely controlling local molecular structures.

This position involves experimental research focused on the development and advancement of Photon-STM. The project aims to investigate and control the local structure, conductive properties, and optical responses of single molecules and thin films at the atomic scale. Through this work, we seek to uncover the correlation between local structures and energy conversion functionalities, ultimately establishing the fundamental principles of a new field in nanoscale energy conversion science.

Research Scientist or Postdoctoral Researcher: 1 position. In principle, Postdoctoral Researcher is defined as those with a doctoral degree of 5 years or less. Research Scientist is defined as those with a doctoral degree more than 5 years. The applicant will be assigned to an appropriate position based on his/her ability, aptitude, etc.

The difference in positions is as follows:

• Research Scientist Carries out research and other work in accordance with laboratory research themes.
• Postdoctoral Researcher Carries out research and other work in accordance with laboratory research themes under the mentorship and training of supervisors.

Applicants should possess strong communication skills and the ability to collaborate effectively with both internal and external research partners.

Postdoctoral researchers must have obtained a Ph.D. in a relevant field within the past five years, or be expected to obtain the degree by the start date.

Research scientists should have obtained a Ph.D. in a relevant field more than five years prior to the start date.

RIKEN Wako Campus (2-1 Hirosawa, Wako, Saitama 351-0198). RIKEN may order the employee to change work locations, if necessary.

A one-year fixed-term employment contract, renewable based on evaluation, within a period of 3 years from date of hire. RIKEN may adjust the above maximum period of renewability based on a) the employee's abilities, work load at the time of contract completion, performance and work attitude and b) the continuation of the employee's center, laboratory or project and RIKEN's management situation and budget at the time. In principle, employment contracts will not be renewed for individuals older than 70 years.

In principle, the first two months of employment are considered a trial period. Salary will be an annual salary based on experience, ability, and performance, and will consist of a base salary and a variable salary. The variable salary will be determined each fiscal year based on experience, ability, and performance. Discretionary work, commuting and housing allowances will be provided. Social insurance will be applied.

The approximate amount of salary at the time of employment: The total amount of monthly discretionary work allowance and monthly salary at the time of hiring will be 431,790JPY or more for Research Scientist and 367,925JPY or more for Postdoctoral Researcher.

RIKEN has a telecommuting system, but this position requires attendance at the work location. Therefore, the telecommuting system is not available for this position, in principle.

This position falls under the specialized duties discretionary work system; one working day will be calculated as 7 hours and 30 minutes. Days off include public holidays, New Year's holidays (Dec. 29 – Jan 3), and RIKEN Foundation Day. Paid leave includes annual paid leave (up to 20 days depending on the month of employment), special paid leave (caring for a sick child, family nursing care, etc.), and work life balance holidays (up to 7 days depending on the month of employment). There are also additional leave systems such as maternity leave, childcare leave, and family nursing care leave. Smoking is entirely prohibited on site. These and other provisions are in accordance with RIKEN regulations. Mandatory membership in the RIKEN Mutual Benefit Society (RIKEN Kyosaikai).

Eligible to apply for the MEXT Grants-in-Aid for Scientific Research (Kakenhi).

RIKEN is actively undertaking initiatives to promote gender equality and diversity, and moving forward with the establishment of a diverse and vibrant research environment. If multiple candidates are found to have the same aptitude following a fair assessment, active efforts will be made to recruit female candidates.

The Wako Campus has an on-site daycare, RIKEN Kids Wako. For details, please send an email to kids@riken.jp.
