Software Engineer, Backend - Trust and Safety - US App

Introduction

Our Mission

Mercari has sought to expand overseas from the outset. This led us to enter the US market in 2014, the year after Mercari’s founding. The US is home to people of diverse backgrounds, of many different races, nationalities, and religions. Laws and culture also differ from state to state. Growing our US service requires grappling with complex problems and issues. This is exactly why we think of the US as a microcosm for our future global expansion. It’s an extremely important country for us, where we cannot afford to fail. While this makes it much more difficult than our Japan-side operations, our US business contributes greatly to achieving Mercari’s mission, and we will continue to face the challenges of the US market going forward.

Our Culture

To achieve our mission at Mercari, our organization and each of our employees share the same values and perspectives. Our individual guidelines for action are defined by our three values: Go Bold, All for One, and Be a Pro. Our organization is also shaped by our four foundations: Sustainability, Diversity & Inclusion, Trust & Openness, and Well-being for Performance. Regardless of how big Mercari gets, the culture will remain essential to achieving our mission and something we want to preserve throughout our organization.
