We dare to believe that we do not need a clear vision to create a future beyond our imagination. PayPay will always stay true to our roots and realize a vision (future) that no one else can imagine by constantly taking risks and challenging ourselves. With this mindset, you will be presented with new and exciting opportunities on a daily basis and have the opportunity to grow and reach new dimensions that you could never have imagined. We are looking for people who can embrace this challenge, refresh the product at breakneck speed and promote PayPay with professionalism and passion.

OUR VISION IS UNLIMITED_

我々は自分たちの想像を超える未来を創るためにあえて明確なビジョンは必要ないと考えています。常にDay1であるスタンスを忘れずに、誰もが想像できないようなビジョン（未来）を実現していくのがPayPayです。

この壮大なビジョンに前向きに取り組み、他社に真似できない圧倒的なスピードでプロダクトを磨き上げ、日本のキャッシュレス決済、またそれを使用した金融ライフプラットフォームとしての普及を一気に推進することにプロフェッショナルとして情熱を持って取り組み、自ら課題発見し、周囲と協力して新しい価値創出を共に推進する仲間を募集します。
