Introduction
Our Mission
Building trust for a seamless society. We challenge ourselves daily to achieve this mission. Merpay's business started as a payment service, but that was just our first step towards achieving the mission we envision. We want to create a society where anyone can realize their dreams through a new ecosystem centered not only on this payment service, but on credit. Let's work together to update society's deinition of "payment," "credit," and society itself.
Our Culture
Mercari’s culture has been central to the company since our founding, with the three core values of Go Bold, All for One, and Be a Pro. In addition, the “Trust & Openness” value was introduced to embody our culture of mutual trust, where information remains transparent and rules are kept to a minimum. Regardless of how big Mercari gets, the culture will remain essential to achieving our mission and is evidenced throughout our organization.
Position Overview
Work Responsibilities
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.”
Merpay has multiple projects moving in different vectors simultaneously, and the teams of 10 or so members which comprise each project have between 1 to 3 iOS engineers on board. Integration with the Mercari app requires our engineers to communicate with the Mercari teams and study the tech used by the Mercari app, calling for a high level of professional skill from our engineers.
In terms of technologies, our development uses simple architecture based on MVVM.
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 AltConf, iOSCon, try! Swift, and iOSDC.
