KabuK Style Inc.のProduct Analyst / Associate Product Manager - Payments / Integrationsの求人

KabuK Style is a travel tech company that provides the travel wallet service "HafH" with the mission of "Creating infrastructure for a society that embraces diverse values as they are."

As the first step toward building this world-changing infrastructure, we launched HafH in April 2019.

Currently, we have partnered with over 10,000 accommodation facilities across 130 countries and regions, with more than 120,000 members using our service.

We continue to expand as a platform that supports diverse lifestyles while revolutionizing the travel and hospitality industry, making travel easier, more convenient, and more affordable.

This is a hybrid role combining data analysis and product ownership. You will not only analyze data and surface insights, but also help define product behavior, shape requirements, and drive improvements across the platform.

You will start as an individual contributor, working closely with Product, Engineering, and Finance. Over time, you will take on increasing ownership of specific product areas and play a key role in shaping how our platform evolves.

We care more about your ability to work with complex systems and data than specific titles or years of experience.
