Team’s Mission / Work Responsibilities

Team mission and expectations of the role

• Build a Global Crossborder e-commerce product with a large selection of unique items from individual sellers and businesses from around the world, and expanding to over 100 countries worldwide.

Specific work responsibilities include the following: 

• Design and implement solutions for both individual users and businesses
• Work extensively with stakeholders external to the team to enhance solutions from the existing product and architecture owned by other teams
• Contribute to the product roadmap and its execution, working closely with product managers, designers, quality assurance and other stakeholders

Unique and Bold Challenges

• Mercari has been operating marketplaces localized in two countries, Japan and the United States, and the Crossborder team aims to develop a new product that can be deployed globally, enabling deployment in over 100 countries. For requests from each region, it must be developed with a global perspective, including standardization and consolidation to avoid excessive localization, enabling/disabling features on country-based feature flags, and implementing internationalization (i18n) capabilities.
• Additionally, to realize Crossborder e-commerce and local business integration, collaboration with numerous third-party vendors is necessary. This experience will help you gain diverse business knowledge and apply it to engineering in cooperation with the Business Development, Legal team, and other departments.
• The Global Product Project itself is currently in the startup phase. Several directions and solutions are being considered. Several existing projects have yet to be finalized. Trade-offs will have to be made to build a strong foundation while assuring a reasonable time to market. The team must balance short-term initiatives and the long term goal for the Global Product. Constructive discussions that transcend individual job roles, whether you are an engineer or a Business Developer, are essential for moving forward effectively.
