• Demonstrated track record of expanding existing accounts and securing multi‑year renewals with enterprise‑scale customers.
• Strong commercial mindset with experience in value‑based selling, contract negotiation, and revenue forecasting.
• Fluent English communication skills (both written and verbal); additional European language proficiency is a distinct advantage.
• Passion for climate action and a solid understanding of carbon markets, carbon credits, or CDR technologies.
• Self‑starter attitude, comfortable thriving in a fast‑moving, early‑stage startup environment.
• Ability to influence senior stakeholders (Director/VP level) and occasionally present to C‑suite executives.
• Willingness to travel across the EMEA region on a regular basis (up to 20 % of the time).

Preferred Qualifications & Experience

• Background in consulting, advisory services, or account management within sustainability‑focused organisations.
• Experience working with climate‑data platforms, carbon‑credit registries, or environmental‑impact reporting tools.
• Familiarity with regulatory frameworks such as the EU Emissions Trading System (ETS), Article 6 of the Paris Agreement, or voluntary carbon‑market standards.
• Advanced degree in environmental science, business, finance, or a related discipline.
• Proven ability to lead complex, multi‑stakeholder projects from inception to delivery.
