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

The mission of our SRE team (which 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 must be capable of scale-out, and we need to always consider room for the growth. Since Paypay's system is highly mission-critical, handling payment solutions - our top priority for the system is to be able to provide stable service.

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