Why We Hire 

GATD is strengthening HR Business Partnering for its teams in Japan. This role gives managers and employees in Japan a dedicated HR partner who understands both the business and the local context, with a focus on performance management, talent management and talent development. 

It suits someone early in their HRBP journey who wants to grow quickly. You will own real work from the start, get close coaching from your manager, and work with HR colleagues across Japan, Singapore, India and China. We value frank conversations: you will hear clearly what is working and what is not, and we want you to tell us the same. 

Candidates with HR generalist, talent management, learning and development or HR operations experience who want to move into business partnering are welcome. 

Position Details 

This role is the day-to-day HR partner for GATD managers and employees in Japan, reporting directly to the business unit HR lead based in Singapore. You will own agreed HR activities for the Japan teams, handle most people matters independently, and work with your manager and the relevant Japan HR teams on complex or sensitive cases. The main focus is performance management, talent management and talent development, helping managers grow their people and teams. 

Key responsibilities are below. You will be developed into the full scope step by step, with coaching and support from your manager. Related duties may be added as business needs evolve.

Work Environment
