About Green Project Technologies

Using Green Project’s platform, businesses of any size can begin tracking and monitoring their footprints. Ultimately, our platform provides the tools our customers need to begin tracking and reducing their corporate carbon footprint in compliance with the GHG Protocol.

About the role 

Join Green Project as a Customer Success Representative, Sustainability and be a part of a fast-growing climate tech company that's making a positive impact on the environment. As a crucial member of our team, you'll be at the forefront of helping our clients better understand their carbon footprint. With end-to-end communication and close collaboration, you'll be a trusted advisor providing guidance on how to best utilize our suite of digital solutions across carbon accounting and supply chain engagement. 

In essence, your role involves:

• Own a portfolio of customer accounts, managing the full post-sales lifecycle: onboarding handoff, adoption, renewals, and expansion
• Guide customers through supplier engagement campaigns — helping them mobilise their supply chains to collect emissions and decarbonisation data on the Green Project platform
• Build strong relationships with sustainability, procurement, and ESG stakeholders at customer organisations
• Conduct regular business reviews to track programme performance, surface insights, and identify growth opportunities
• Act as the regional voice of the customer internally, feeding back product and process improvements to the wider team
• Support commercial outcomes by identifying upsell opportunities and managing your customers' renewals
• Contribute to localising CS playbooks, templates, and communications for the Japanese and broader APAC market

• 3–6 years of experience in Customer Success, Account Management, or a client-facing role in a SaaS environment
• Native or business-level Japanese; business-level English (written and spoken)
• Genuine interest in sustainability, ESG, or supply chain — you don't need to be a carbon accounting expert, but you should care about the mission
• Strong relationship-building skills and cultural fluency in Japanese business contexts (keigo, stakeholder hierarchy, consensus-based decision-making)
• Comfortable managing multiple accounts and complex, multi-stakeholder programmes simultaneously
• Experience working with CRM tools; HubSpot experience is a plus
• Collaborative and comfortable working across time zones with distributed global teams

Nice to Have

• Experience at a foreign-owned or international company operating in Japan
• Background in sustainability, climate tech, or supply chain management
• Familiarity with Scope 3, GHG reporting frameworks (GHG Protocol, CDP, CSRD), or supplier engagement programmes
