Job Description ■Introduction
The company is looking for a server-side engineer for Nulab Apps, which develops the company's accounts, payments, authentication, and other functions.

Accounts are the common infrastructure that supports the company's services (Backlog / Cacoo), including single sign-on, organization and group management, and billing systems.

From 2020, the company has also started offering “Nulab Pass”, which allows accounts to use SAML authentication as well.

You will be responsible for server-side development and operations in this Apps team. The team consists of 14 members including the manager. The team is divided into two teams: the Authentication Team and the Payment Team.

■Purpose of this Recruitment
・Currently, the number of users of each service continues to increase, and there is an increasing number of cases of adoption by large companies.
・The server side of the Apps team is currently under development and operation by 7 to 8 people, but by expanding this to around 10 people, they plan to further strengthen their development and operation structure.

■Responsibilities
・You will be responsible for the development and operation of Nulab Apps in a team whose motto is "Creating teams around the world where everyone can enjoy working together by providing a workspace where people can focus on collaboration in peace".
・Specifically, the functions include single sign-on with SAML authentication, user provisioning, audit logs, and centralized account management, and this is an important position that also involves security and governance of Nulab services.
・Therefore, in this position, you will often collaborate with other product teams such as Backlog and Cacoo to promote development.
・Although development and operations are sometimes carried out under the direction of the product owner, the team members are highly motivated to improve the service by themselves. This is an environment where newcomers can make use of their past experience and ideas.
・You will also be responsible for replacing old technology stacks with modern frameworks. On the server side, rewriting from Java to Kotlin is currently underway.

■Development Environment

Backlog is a tool designed to make projects fun and facilitate communication within a team.

It is a project management tool that supports the work of many people.
