Backend Engineer (User facing app)|Backend Engineer (User facing app)

  • Manufacturer, Manufacturer-Automotive, Micromobility, Software platform, Transportation, Trafic
  • IT, Product Engineer (Hard/soft)
  • Tokyo
  • ¥8,000,000~¥15,000,000

A startup company that provides electric kickboards and electric bicycle sharing services with the aim of popularizing micromobility.
The company has set up stations mainly in urban areas and is developing a system that makes short-distance travel easy and efficient.
The service is easy to use via a dedicated app and is attracting attention as a sustainable means of transportation.
We are developing sustainable mobility services that reduce environmental impact and solve urban transportation issues as well as rural transportation issues.

Our software development is divided into two areas: for users (iOS and Android apps) and for back operations that support operations.

For users, we develop functionality for mobile applications, primarily for customers who ride. We will develop the UX to deliver the best ride experience through the mobile application. The product team, consisting of product managers, designers, OS engineers, Android engineers, and QA team, will continue to make improvements based on user feedback obtained from user interviews and data analysis.
The team is mainly responsible for the development of APIs for applications, but collaboration with various systems is also essential for the stable supply and safety and security of the mobile infrastructure. We will work with IoT modules installed in vehicles, sensors, operation functions to link reports from users to staff, and external systems for route guidance, etc. We will also develop API development peripheral functions. We may also develop management tools for functions for users as well as API development peripheral functions.

The backend is developed mainly in TypeScript, with CloudFunctions for infrastructure and Firestore for database. Refactoring is performed to eliminate technical debt and bottlenecks throughout the system in collaboration with the client apps and IoT teams. In the mid- to long-term, the team may also adjust the rearchitecture, etc., without assuming the existing configuration.

Job Description

  • Responsibilities
    About the Server Team]
    ◆Features
    Our server team utilizes many managed services such as CloudFunctions and Firestore, and has constant metrics maintained by the SRE team, making it easy to focus on writing application code.
    With this behind us, we have been working to centralize the business logic of multiple client applications for consumer and back-office operations on the server. Therefore, it is not easy to implement complex specifications in a concise and robust manner on the server, but it is an environment where it is easy to deliver value to the product due to the breadth of influence and mobility.

    In addition, while the product manager organizes the requirements and priorities for the specifications, there is a lot of discussion and adjustment to the specifications and requirements from a technical perspective. This is an environment where product growth is considered from a long-term perspective rather than forcing implementation and creating technical debt.

    We use Firestore, which has multi-tenant characteristics, as our main DB. Therefore, in order to manage not only the backend but also client applications with a common DB schema, we are developing web applications and backend with mono-reporting.

    ◆Scale and structure
    The server team consists of 7 full-time employees and about 10 outsourced workers. (As of 2025/01)
    The team consists of backend engineers and frontend engineers, who are in charge of consumer and back-end operations, as well as infrastructure development.

    We usually collaborate with 3 product managers, 2 designers, 5 app engineers, and 4 QA members, and sprint once every 2 weeks to meet the release cycle of the app.

    -Experience developing with TypeScript (approx. 2+ years)

    -Experience in an organization that does agile or lean development, etc.
  • Preferred
    Experience focusing on process improvement for teams such as scrum masters
    - Experience promoting and implementing spontaneous refactoring outside of feature development
    - Experience developing products using Firebase products
    - Experience with Google Cloud Platform certifications and use
