Call for applications for PFN summer internship 2018


Preferred Networks (PFN) is looking for enthusiastic interns who can work with us in our Tokyo office this summer. Students who participated in the previous programs are also eligible to apply. We welcome students who want to help us develop new technologies, software, and services in a wide range of computer science areas including machine learning.  


Important notice:

Note that this program is only for students who already have visa eligibility to work as an intern this summer in Japan. We are not accepting applications from students who need support for obtaining the designated activity visa to work as an intern because the due date for processing such applications has already passed.


Guidelines for applicants


● Characteristics of PFN Internship

  • Over the two-month period, PFN engineers will be assigned to work with each of you as a mentor. You will have opportunities to discuss and study your theme with specialists in various fields including deep learning, computer vision, natural language processing, robotics, bio-healthcare, reinforcement learning, and distributed processing.
  • After the internship, you can make public your research result by writing a paper or making it OSS, to the extent possible.  


● Period

Start date:Between late July and early August depending on your schedule

End date:Friday, Sept.21, 2018

※You can choose to continue to work in the week of Sept. 24-28 under the same terms and conditions.

Note that this year’s internship will end on Sept. 21 in consideration of the fact that many schools start their fall semester in late September. If you need more time to finalize your research or want to spend more time with our staff, you can continue to work until the end of September under the same terms and conditions. We understand you may have school or family commitments during the internship which might range from lab activities to attending academic conferences, to returning home. We are very flexible about your need to take days of absence due to these reasons.


● Key Qualifications

PFN is seeking highly motivated and skillful individuals who can develop applications, tools, etc. on your own. Having knowledge or development experience in the themes listed below is a plus but not a must. Minimum requirements are:

  • Currently enrolled in high school, technical college, university, or graduate school. Negotiable for those attending other higher educational institution
  • Fluency in Japanese or English
  • Strong communication skills
  • Prior experience in programming (any language)
  • Willingness to come to work in our Tokyo office on weekdays

Do not hesitate to apply even if you don’t have prior experience in full-scale development.
