PayPay

With over 70M million registered users (as of July 2025), PayPay is the country’s most popular mobile wallet used by approximately one out of every two smartphone users in Japan.

Our international origins make us diverse at the core

PayPay started as a collaboration between Paytm, SoftBank, and Yahoo Japan, bringing together teams in Canada, India, and Japan. As we’ve grown, we’ve continued to embrace this diversity, and about 50% of our engineers are non-Japanese.

Japanese NOT required

Despite having a product aimed at the Japanese market, we’ve built our company so that English-speaking engineers can contribute at all levels, and a lack of Japanese ability will not hold you back. About 80% of our product team speaks English, and we have interpreters who can provide simultaneous translation when necessary.

If you’re an international engineer, we’ll also assign you a dedicated HR person who can help you with any Japanese translation or bureaucracy that comes up in your day to day.

Incredible scale using the latest technologies

PayPay launched on October 5th, 2018, making us still quite a young service. Despite this, we have built a system that handles over 1000 transactions per second. This combination of both scale and modern technologies makes working with us a rather unique opportunity.

Make your own decisions

Despite our scale, our engineers still have a great deal of autonomy, both from the perspective of the choice of technologies you apply, and also your role within the company. If you see something that can be improved, you’re encouraged to take it on. There’s no need to be constrained by an overly restrictive job description, and you can easily change roles within the company.
