About Moneytree

Moneytree is a fin-tech start-up founded by three foreign entrepreneurs in Tokyo.

Their Moneytree Link product provides a "utility layer for connecting financial services" that serves banks and other fin-tech companies, but they also have a popular consumer app that helps people manage their finances.

They're an international company with an English-first work environment and a high technical skill level for engineers. Truly a really great place to work!

Salary
Moneytree's salary structure is designed to offer a base salary along with stock options. Stock options are still a relative rarity in Japan, so Moneytree is one of a reasonably small list of Japanese companies offering them.
Japanese Language Policy
Moneytree does not require Japanese language skills for their engineering positions, though it is an advantage.

As a customer-centric company building products for Japanese customers, Japanese fluency is required for product managers and product designers to do user research, product discovery, etc.
Visa Sponsorship
- With the current pandemic, we are only accepting applicants with valid working visas in Japan.
- We offer support for visa renewal to new hires with valid working visas in Japan.
Paid Leave
Moneytree offers 20 paid holidays in addition to 10 sick/care leave days.

The Standard paid leave in Japan is 10 for an employee's first year, so this is what you'll get at the majority of companies. The fact that Moneytree doubles this to 20 really makes them stand out from other companies in Tokyo.

And then there's their sick day policy. Since these aren't legally mandated in Japan, most companies don't have them at all. Moneytree really goes above and beyond here with 10.
