Seeking a Technical Staff I or II(W658)

Research field and overview

Emergent Soft System Research Team (Team Leader: Dr. Takao Someya) focuses on making full use of the novel soft electronic materials such as novel organic semiconductors in order to fabricate emergent thin-film devices and, subsequently, to realize emergent soft systems that exhibit super-high efficiency. Now we are focusing on establishing photoelectric conversion devices with ultimate flexibility and/or light-weight. The target devices include flexible photodetectors, light-weight solar cells and integrated imaging systems.
We are thus seeking a highly motivated and experienced engineering scientist to join Emergent Soft System Research Team at RIKEN. Candidates must have Ph. D degree and are supposed to have experience related to fabricate organic devices and sensors, and device fabrication/evaluation.

Salary and benefits

  1. A one-year fixed-term employment contract, renewable based on evaluation, to a maximum 10 years*1 from the initial date of hire.
  2. 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 65 years.
  3. The employee’s period of fixed-term employment cannot exceed 10 years from the initial date of hire (or 10 years from April 1, 2013 for fixed-term employees already at RIKEN prior to this date).
  4. When the center to which the Employee is affiliated is scheduled for a final review in FY2022 and it is decided that the Employee's research will not be continued, the provision given above for projects of limited duration applies and the Employee's contract will not be renewed for the FY2023 year that would extend employment beyond the center's final fiscal year.
  5. Technical Staff: When the Employee’s research is scheduled to be reviewed every three years from the original date of hire at CEMS, and when it is concluded that there is reason* to believe it will be difficult for the research (or technology development) to be continued, the employment contract will not be renewed for the next year. (*The reason may relate to the Employee's abilities, performance and/or work attitude.)

The salary system is annual and will be commensurate with qualifications and experience. Commuting and housing allowances will be provided. Social insurance will apply. Mandatory membership in the RIKEN Mutual Benefit Society (RIKEN Kyosaikai) is required.
Days off include public holidays, New year’s holidays (Dec. 29 – Jan. 3), and RIKEN Foundation Day.
These and other provisions are in accordance with RIKEN regulations.

RIKEN promotes a Gender Equity Program by taking various measures to create an equitable workplace where both men and women are able to give full rein to their talents and abilities. When the abilities of candidates are judged to be equivalent through a fair and impartial evaluation process, preference will be given to females.
