(DSOC) Backend Engineer – Sansan

 

Job Description

We seek a knowledgeable and experienced software engineer to work in DSOC’s Nayose Group.

The Nayose Group is responsible for analysis and integration of Sansan’s digitized business card data and other contact data from various sources. Principally, it is responsible for recognizing which data corresponds to which individuals and companies, and effectively integrating them into our proprietary management system.

This process is essential to both of Sansan’s two main businesses; the B2B product Sansan, and the B2C product Eight. Sansan is Japan’s leading business card-based contact management solution for corporations with over 7000 corporate customers, while Eight has over 2.5 million individual users.

With Sansan’s global expansion underway, in order to further improve the efficiency and quality of integration of non-Japanese people and companies, we seek a non-Japanese engineer to join the Nayose Group. The role will involve UI and Web API development, as well as data handling and transactions, in close collaboration with DSOC’s R&D Team and Sansan’s Global Product Group.

We are driven by innovation, and are looking for a passionate and intelligent engineer who will demostrate initiative and ambition, devise new solutions and help drive the project ever forwards. We combine data, technology and operational acumen to generate unrivalled value and quality. We aim to be the best not only in Japan, but the world.
