Job Description / 業務について
We are looking for senior backend engineers to build, or rebuild, rock solid services with a laser focus on scalability and maintainability.
PayPay Card aims at revolutionizing the credit card industry, making payment easier than ever, from two different angles:
Bring the credit card experience to the next level: we have many functionalities in the pipe to improve our product, not to mention the integration into the PayPay ecosystem as PayPay Card is part of the PayPay Group.
(Re-)architect our systems landscape: we want to reassess and fix the behind-the-scenes to power a top-notch user experience. It is bundled with difficult design challenges to solve: we simply want to get it right.
As a fast-paced company leading the payments industry, we need our engineers to be versatile and enthusiastic to take on new challenges in order to stay at the forefront. Indeed, we strive for continuous improvement within our systems as well as outside our systems. Additionally, we value communication, to smoothly cooperate with other teams, and inclusivity, to efficiently navigate in a multicultural environment.
私たちは、スケーラビリティ(拡張性)とメンテナビリティ(保守性)に徹底的にこだわり、極めて堅牢なサービスを構築、あるいは再構築していただけるシニアバックエンドエンジニアを募集しています。
PayPayカードは、これまでにない最高のユーザー決済体験を提供することを目指し、次の2つのアプローチからクレジットカード業界に革命を起こそうとしています。
クレジットカード体験を次のレベルへと進化させる:プロダクトの体験向上や機能拡張のために、数多くの開発ロードマップが控えています。また、PayPayグループの一員として、「PayPayエコシステム」とのシームレスな統合・連携も強力に推進しています。
システムアーキテクチャの再構築:最高のユーザー体験を裏側から支えるために、現在のシステム構造を再評価し、根本から最適化(刷新)したいと考えています。解決すべき技術的難題は非常に多いですが、私たちは小手先の修正ではなく、アーキテクチャとして「あるべき姿」を愚直に実現することを目指しています。
業界をリードする圧倒的なスピード感の中で、常に最前線に立ち続けるために、エンジニアには領域にとらわれない柔軟性と、新しい挑戦に意欲的に取り組む姿勢が求められます。私たちはシステムの内外を問わず、絶え間ない改善を追求しています。また、他チームと円滑に連携するためのコミュニケーション力や、グローバルな環境で最大のパフォーマンスを発揮するための多様性を重視しています。
