About PayPay

With over 30 million registered users (as of June 2020), about a quarter of Japan’s population, PayPay is the country’s most popular mobile wallet.

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.

Free Japanese lessons on company time

Of course, living in Japan, having Japanese skills will help to make your personal life more fulfilling, and so we do offer free Japanese lessons that can be scheduled during normal working hours.

Work remotely and on your own schedule

In response to COVID-19, we moved to working remotely. This proved so successful that we’ve announced our “Work From Anywhere at Anytime” policy. Even after COVID-19 settles down, we’ll continue to allow employees to work from anywhere in Japan, and set their own hours.

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.

Our response to COVID

We’ve transitioned to remote work to ensure employees safety during COVID, and we’ll continue this even after it subsides. While we’re open to considering engineers looking to relocate to Japan, travel restrictions have made it difficult to give a clear timeframe for relocation. Should we extend you an offer, we’ll apply for a certificate of eligibility for you, that will make obtaining a visa trivial once the borders open, and we’re open to making special accommodations, such as starting you on a remote contract.

Hiring Process

  1. Application Review (1-2 weeks). We review your profile based on your submitted materials.
  2. Code challenge (online). We send you a code challenge after reviewing your resume. Please be prepared to take code challenge after submitting your application! It takes at most 3-4 hours to complete.
  3. 1 - 3 Interviews (online). You will have 1 to 3 interviews with our engineers and HR.

About the position

PayPay is looking for a SRE/Platform Engineer to work on our payment system to deliver the best payment experience for our Japanese customers.

Our ideal candidate is a problem solver and a learner at heart. You should have a very high degree of comfort in a programming language of your choice. We offer a flexible work schedule and you get your choice of tools (both hardware and software) and most importantly, the opportunity to work on tough problems with the brightest minds around you.


The mission of our SRE team ( we call “Platform team” at PayPay) is to build and architect stable infrastructure so that we can provide secure service to all the customers with our highest speed.

Our number of transactions as well as users have been increasing day by day since our first product release. The infrastructure/system has to be capable of scale-out, and we need to always consider room for the growth. Since Paypay’s system is a highly mission-critical, handling payment solutions - our top priority for the system is to be able to provide stable service.

From risk-hedge perspective, it is important to assure our infra is maintained properly with high level of usability so that even if our instances get down, we can continue our service.

Our current phase is not yet “maintenance” phase - as a SRE engineer, you will be required to architect the whole system in a scalable manner with employing a variety of technologies.

Main responsibilities:

Architect, maintain and tune our PayPay infra system with the following tech domains:

We rotate roles and responsibilities among those tech stacks, and you will be able to experience a wide range of technologies.
