Introduction

Circulate all forms of value to unleash the potential in all people

"What can I do to help society thrive with the finite resources we have?" The Mercari marketplace app was born in 2013 out of this thought by our founder Shintaro Yamada as he traveled the world. 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. For more information about Mercari Group’s mission, see Mercari's Culture Doc.

Equal Opportunity Hiring

Here at Mercari, we work to realize a world in which no one’s potential is limited by their background and everyone has the opportunity to freely create value. We also firmly believe that a mindset of Inclusion & Diversity is essential for us to achieve our mission. This, of course, extends to our hiring practices as well.

Mercari is committed to eliminating discrimination based on age, gender, sexual orientation, race, religion, physical disability, and other such factors so that anyone who shares our mission and values can join us, regardless of their background. For more details, please read our I&D Statement.

Team’s Mission / Work Responsibilities

Team mission and expectations of the role

We are looking for a professional iOS engineer to work on everything from planning to development for Merpay’s new payment and finance services, based on the company’s mission of “building trust for a seamless society.”
At Merpay, each business area is organized into a unit called a program. Each program has several iOS engineers and promotes our respective businesses.
In terms of technologies, our development uses architecture based on MVVM for UIKit, and Redux inspired architecture for SwiftUI.
We work on implementation of unit tests and UI tests, while also working to constantly test these with CI and improve coverage. While naturally the team is involved with developing features for projects, our company culture encourages engineers to proactively improve development processes, automate processes using CI, and other tasks. We believe that this culture allows our software engineers to improve their abilities not only in iOS, but in many other domains as well.
Aside from that, we also encourage and look very favorably on external output. This includes:
- Speaking at conferences both in Japan and abroad, such as try! Swift, and iOSDC.
- Writing for the Mercari Engineering Blog
- Contributing to open source software (OSS)
