Job Description

Our Tokyo engineering team is hiring a backend software engineer to contribute to the development of our Warehouse Management System (WMS) and its companion Handy Terminal device, both of which are integral to our logistics product suite. These systems are designed to seamlessly integrate with our state-of-the-art ASRS systems. The team’s mission is to build and maintain a robust, tested, and high-performance backend architecture, including databases and APIs, shared across all deployments. While the role emphasizes strong software development and engineering practices, we also value open communication and a collaborative team spirit. 

In this role, you will: 

• Design, develop, and maintain a key component that supports the efficient flow of supply chain operations. 

• Enhance code quality and ensure comprehensive test coverage through continuous improvement. 

• Collaborate effectively with cross-functional development teams to integrate solutions and align best practices. 

Requirements

Minimum Qualifications: 

• 3-5 years of professional experience with Python, with a focus on versions 3.10 and above. 

• Practical experience working with web frameworks such as FastAPI or Django. 

• Strong understanding of SQL database principles, particularly with PostgreSQL. 

• Proficiency in testing and building automation tools, including pytest, GitHub Actions, and Docker. 

Bonus Points: 

• Experience with NoSQL databases, particularly with Redis. 

• Practical experience with asynchronous programming (e.g., asyncio) or message bus systems. 

• Ability to clearly articulate technology choices and rationale (e.g., Tornado vs. Flask). 

• Experience presenting at conferences or meetups, regardless of scale. 

• Contributions to open-source projects. 

• Familiarity with WMS concepts and logistics-related processes. 

Is This the Right Role for You? 

• You are motivated by the opportunity to make a tangible impact and deliver significant business value. 

• You appreciate APIs that are thoughtfully designed with clear, well-defined objectives. 

• You thrive on understanding how your work integrates and contributes to a larger, cohesive system. 

• You are proactive and self-directed, identifying potential issues and gaps before they become problems in production. 

Benefits

• Competitive salary package. 

• Opportunity to work with a highly talented and diverse team. 

• Comprehensive visa and relocation support.
