We believe that by circulating all forms of value, not just physical things and money, we can create opportunities for anyone to realize their dreams and contribute to society and the people around them. Mercari aims to use technology to connect people all over the world and create a world where anyone can unleash their potential.

Working at Merpay

Merpay is home to some of the greatest experts within Mercari Group. Our commitment to a culture of openness allows members to discuss architecture on Slack channels organized by business domain, send pull requests to each other on GitHub, and share knowledge on the internal Wiki. We hold “Go Friday” and other weekly study groups for engineers but open to all, encouraging engineers to help one another grow. Some members have no experience developing in Go before they join, but we help turn them into Go enthusiasts early on through involvement in our internal Go community and “Gopher Dojo,” our short-term, intensive training. Members further develop their expertise while demonstrating their abilities at both internal and external engineering community events.
