Our vision is to simplify the logistics system in order to onboard Mercari systems for both local and global shipping. We are currently working with multiple shipping partners in order to provide reliable shipping experience for our users. Managing all these partners and their operations is challenging.

Work Responsibilities
- Design and develop solutions for internal users and external partners.
- Working closely with product managers and business development teams to help them plan and execute the product roadmap.
- Work closely with external partners and understand their problems and system limitations and design solutions which can serve both Mercari and partners.
- Work with internal teams and stakeholders for designing solutions and enhancing existing features which depend on teams across the organization.
Unique Challenges
- Mercari is a leading C2C marketplace in Japan and aims to provide excellent services to our customers. Shipping is one crucial system which relies on external partners and has dependencies on their systems. And we are always looking for ways to expand our business by providing innovative features. In order to do that we also need to make sure our backend systems are capable of managing additional feature development and load from other services. This is a unique challenge for us to manage the expectations of our stakeholders and partners and make sure our systems don’t have limitations or become bottlenecks.
- Additionally we are expanding our business globally and by having more partnerships with shipping companies. Which means that backend systems should be able to integrate with external and global partners. Partner systems as well keep evolving and changing to accommodate changing business needs which means we also need to develop our systems in a way which can accommodate such changes coming from partners.
- We manage many services and in order to keep it sustainable, we keep iterating and thinking on how and what services we can merge or migrate in order to keep our life and day to day work easy.
