One-stop platform to manage your personal investments.

Pafin provides an investment management platform for individual investors in Japan, known as Cryptact Grid. The first service launched on Grid is Japan’s largest service for profit/loss calculation and tax assistance in cryptocurrencies. The second service, Ideabook, in which you can openly share investment ideas, is gaining attention from financial institutions for its possibility.

We communicate internally in English, so no Japanese ability is required. However, we are currently looking for candidates already based in Japan.

Technical cofounders

Two of our three co-founders have an engineering background. They join the development of our products on a daily basis, and contribute via things like coding, reviewing, and testing, together with the engineers.

International engineering team

Our engineering team is made up almost entirely of international people from places such as France, Belgium, US, China, India, Italy, New Zealand, and Nepal.

Working environment

  • The office is 3 minutes walk from Kojimachi station, Chuo-ku, Tokyo, Japan.
  • Upon onboarding, you can choose your preferred development environment (an OS of your choice, PC, monitor, mouse, etc) within a certain budget.

Free Japanese lessons

Depending on your level of Japanese, you’ll be able to enroll in a Japanese lesson held onsite by inviting a teacher. We regard this as a necessary business skill, thus the lesson is done during business hours, and the firm fully covers the cost. The same would apply to non-native English speakers to take English classes.

Visa renewal support

When it is time to renew your visa, you don’t have to go to Shinagawa, since we’ll take care of the whole process with an external specialist.

Other benefits

  • A housing rent program after the probation period.
  • Employee referral program
  • Annual performance review, including 360-degree evaluations.
