About Mercoin
At Mercoin, we are dedicated to planning and developing services associated with cryptoassets and blockchain technology. In our pursuit of the cryptoasset business, we aim to make it more convenient for users to access financial services within Mercari. This involves enabling users to receive payments for Mercari sales in bitcoin and offering a comprehensive wallet function that encompasses not just Merpay's payment and remittance services but also credit, cryptoassets, and asset management features.
Furthermore, Mercari has embarked on initiatives involving blockchain technologies, which open up new possibilities for individuals to exchange value. Our company's vision is to redefine the concept of buying and selling, making it easy for everyone to exchange value in various forms, including not only physical possessions and currency but also services and digital content, such as non-fungible tokens (NFTs).
Work style
The Mercari Group has assembled some of its most renowned experts into teams that are organized according to specific business domains. Our commitment to fostering an open culture allows team members to engage in architectural discussions through Slack channels, send pull requests to one another on GitHub, and share knowledge via our internal Wiki. We actively promote knowledge sharing and growth by hosting events like "Go Friday" and other weekly study groups, which are open to all, thereby encouraging engineers to support each other's professional development.
It's worth noting that some of our members may not have prior experience in Go development when they join, but we facilitate their transition into Go enthusiasts. This is achieved through their participation in our internal Go community and our "Gopher Dojo," a short-term, intensive training program. As they further hone their skills, our members also have opportunities to showcase their expertise at both internal and external engineering community events.
