Senior Data Engineer

With around half of KOMOJU’s total members (and around 90% of engineers) coming from outside Japan, teams generally use English for written communication(e.g. Slack, Github).

Verbal communication is also primarily in English.

However, quite a few people can speak both English and Japanese fluently, so Japanese may be spoken at times during meetings, especially when they involve teams other than engineering.

Overall, the language spoken depends on the team. The dev team uses mostly English, but the HR team (for example) speaks primarily Japanese.

KOMOJU sponsors visas for candidates living outside of Japan. KOMOJU also helps out with relocation (searching for apartments etc.) but they don’t have a formal policy for this. The support offered depends on each individual case. They do always pay for flight tickets to Japan in the case that someone moves from abroad.

KOMOJU offers a generous vacation policy. In line with standard practices in Japan, employees begin with 10 days of paid time off (PTO) in their first year, with the number increasing in subsequent years based on Japanese labor law.

In addition to this, KOMOJU provides 5 extra vacation days during the summer and another 5 days for year-end holidays.

Employees also receive a day of birthday leave each year. Altogether, this adds up to 21 vacation days annually, not including Japanese public holidays. KOMOJU also offers maternity leave, paternity leave, and sick leave.

Engineering Roles

KOMOJU aims to keep their hiring process thoughtful and efficient. Typically, it involves 3–4 stages depending on the role:

• Initial Screening
• Take-home Exercise
• Technical Interview (Team Interview)
• Final Interview with Leadership

Throughout the process, the team evaluates technical skills and looks for alignment with team culture and potential for long-term growth.

KOMOJU operates as a remote-first company while placing a strong emphasis on personal connections and close collaboration. The company maintains an office in the Kichijoji area of Tokyo, which employees are welcome to visit for in-person collaboration and company events, such as weekly lunches provided at no cost.

Team members have the flexibility to work from anywhere within Japan, as well as up to three months per year from abroad. KOMOJU also offers flexible scheduling, allowing employees to set their own hours as long as they are available during the company’s core hours, Monday to Friday from 10:00 to 15:00 JST.
