It is a marketplace where you can purchase fashion items from all over the world from personal shoppers (sellers) from all over the world.

【Job Description】 

■Responsibilities
You will be in charge of developing new and existing functions for the company's services, with a focus on “BUYMA”.
You will be responsible for the entire system life cycle (design, development, testing, release, operation, defect handling, etc.).
In this position, you will develop in collaboration with the director, designers, and business team in order to achieve the business mission and solve the issues that the product has.

・Develop new features and improve existing features mainly using Ruby on Rails
(Some applications in Java, Python, and PHP may require modifications.)
・Design and develop system architecture considering performance, redundancy, maintainability, and ROI.
(This is an ideal environment for those who want to work on the entire project, including the architecture.)

【Project Examples】
Many projects are in progress, including improvement of existing functions, development of new functions, development of new services, API development, support for large-scale campaigns, and product image measures.

・Renewal of product detail pages and seller management screens
・Development of product search function using ChatGPT
・System integration with overseas stores to strengthen product assortment
・System integration with shipping companies and payment services to diversify delivery and payment methods
・Development of a catalog listing function that consolidates product images and product data
・Development of catalog display functions that consolidate product images and product data,
etc.

■Attractiveness of this position
・Data-driven development based on both seller and buyer data and user behavior is possible. In addition, you can directly feel the results of your project through numerical values (sales, CVR, etc.) and user feedback.

・Currently, BUYMA is largely a monolithic system, but is undergoing system modernization, including a shift to microservices. As BUYMA's service expands, traffic and data will continue to increase, so there is a lot of work to be done in addition to functional development, and you will be able to participate in a challenging project.

・For each project, a small team is formed by selecting members from each job category (marketing, engineers, directors, designers, etc.) as needed. Therefore, each member is given a great deal of discretion and can work with a sense of speed beyond the department. In addition, because there is active horizontal communication, there are many opportunities to deepen knowledge and perspectives other than engineering skills, such as planning and marketing.

■Development Environment and Team
・The entire Service Engineering Division, including those who participate as contractors, consists of approximately 60 people, divided into four sections (Infrastructure Group, Data Technology Group, Application Development Group, and Global Team).

・The development structure varies from team to team. Some teams are led by the director, while others are led solely by engineers. From the planning stage, you can be involved in the end-to-end development of web applications from the screen (other than design) to the DB, and can be involved in a wide range of tasks.

・The company engages in scrum development, and each team holds a morning meeting to share the day's work and issues they are facing, and at the end of each sprint, they review their work. Communication via slack is also very active, and development is carried out remotely as much as possible in an environment that is the same as when working at the office.

・The company encourages activities to improve technology, such as writing a tech blog, conducting in-house study sessions, and participating in technical conferences. There is also a support for external seminars.
*In-house study sessions (free participation) are held weekly, including in-house LT meetings and study sessions for young employees. For details, please refer to the company presentation materials.
