<How to proceed with development>
■ How can I decide what to make next?
Based on the requirements, the designer creates a design, and based on the design, the CTO, engineers, and designers conduct a review. In the sprint planning, engineers identify issues based on the design and requirements and make an estimate. After that, we implement the issues planned in the sprint, create pull requests, review them by other members, and merge them.

■ Task estimation and schedule management
Task estimates are left to the engineers in each area of responsibility.
The overall schedule is managed by the CTO.

■ Development flow
We have adopted a development flow based on Scrum. The duration of the sprint is 2 weeks.
At the completion of each sprint, we conduct a review and discuss how to proceed with the project and what the team should be like.

■ Code review
It will be carried out in two stages: a peer review between engineers and a review by the CTO.
In addition, we also conduct pair projects and mob programming as necessary, and hold review meetings with the entire engineering team for important functions.

■ Software test
Since there are many additions and changes in functions, software testing is mainly unit testing of important functions.
Test automation is an area that we would like to focus on in the future.

<Discretion of development members>
・Personal environment such as OS, editor, and IDE can be used at your own risk.
・Development members in charge of implementation participate in planning decisions.
・Task estimation is done mainly by members in charge of implementation
・Overall schedule management, while checking the results on the way at any time,
We flexibly adjust the delivery date and the functions to be included.

<Attractiveness of work>
・Development and operation of a large-scale service used by 2 million users
・Engineer-led development system without a director
・ An environment where you can actively participate in fields other than your own specialty and aim to become a full-stack engineer
・ Opportunity to be involved in new business launch " " <Issues as a team>
