Our typical clients are European, American and Japanese startups and small-to-mid sized companies working with our teams as permanent and equal extensions to their own software departments.

On behalf of our Client from Japan we are looking for a React Native Developer (with React.js).

About project:
Our client is a fast-growing fintech company based in Tokyo. The company offers its real-time monthly consolidated credit service all across Japan. Our client started Japan’s first instant post-pay credit service for e-commerce customers in October 2014. The main product is an online payment platform which requires no pre-registration or credit card to use; via this service the customers can purchase products online using only a mobile phone number and email address and settle a single monthly bill for all their purchases, either at a convenience store, by bank transfer or auto debit. Customers can use credit funds during a month and then return the balance to zero without paying credit interests.

This service also supports multi-pay installments and subscriptions. There are currently over 4 million accounts in use. This service got the largest investment to date in the Japanese financial tech industry, including PayPal Ventures investment.

• You have a high bar for producing clean, maintainable and testable code
• You have at least strong intermediate level of English

• You love learning and are not afraid to jump in

It’s not expected that you’ll have deep expertise in every dimension above, but you should be interested in learning any of the areas that are less familiar

• Familiarity with creating B2C user experiences
• Experience with financial or payment product

Joining the team you will get

• No open-spaces setup – separate rooms for every team’s comfort and multiple lounge and gaming zones on all of the 3 floors
