Senior Engineer - Frontend（New Product）

Our challenge

UPSIDER is an early-phase startup with less than 40 employees and has been in business for 4 years, and is a product-driven company consisting of approximately 50% engineers. Although it has been less than two years since we released UPSIDER Card, our main business, more than 1,500 companies are currently using our service. We are also very happy that our service is spreading by word of mouth from customers who are satisfied with the quality of our service, and we are currently receiving inquiries a lot of companies, about introducing the service, with almost no marketing costs at this point.

As a new business, we also officially launched "支払い.com”in April 2022, a payment service that accepts credit cards for all bill payments/bank transfers. The service has been used by several thousand companies within two months of its official launch, and is growing rapidly in response to the passionate needs of small and medium-sized businesses. In addition, this business is operated jointly with Credit Saison, which is listed on the Tokyo Stock Exchange Prime Market.

In addition to being an engineer-centered company, we consider UI/UX to be the most important factor in determining the value of our services. In fact, many users have chosen UPSIDER because of its UI/UX, making it an aggressive area that greatly influences the value of our services.

Our challenge has just begun. In addition to the evolution of both businesses, we will continue to launch many innovative new businesses in the BtoB domain and cover the world with the UPSIDER network.
