🌱  About the team 

You’ll join Greenly’s Climate Delivery team, a group of customer-obsessed Climate Experts dedicated to guiding clients through their most strategic climate and sustainability challenges. 🤝

We deliver high-quality climate projects — carbon assessments, lifecycle analyses (LCA), SBTi trajectories, CSRD support — and help organizations turn data and regulations into clear, actionable decisions.

As a team, we:

• Combine analytical rigor with a strong customer success mindset
• Act as trusted advisors, not just technical analysts
• Thrive in a fast-moving, collaborative environment, sharing methods, scripts, and lessons learned
• Work closely with Customer Support, Product, Sales, and Marketing to ensure our clients succeed and our methodologies stay robust 💡

It’s one of Greenly’s most influential client-facing teams: high expectations, complex projects, and real impact on both client outcomes and product evolution. 🌍

🌱 About the role 

We’re looking for a Climate Expert (2–8 years experience) who can blend analytical depth, project management, and confident client communication — someone who is as comfortable working with data as they are leading a meeting.

Your mission:
Drive end-to-end delivery of climate projects (GHG, LCA, SBTi, CSRD…), act as a trusted advisor, and help clients understand what to do next — not just what their footprint is. 🌍

In your first months, you will:

• Take ownership of your first GHG assessment projects
• Lead client meetings (kick-off, methodology, results) in French and English
• Conduct data collection, consistency checks, and methodological analysis
• Translate technical outputs into clear, executive-ready recommendations
• Share feedback with our Product team to improve processes and tools 💡

You will drive:

• Smooth, structured delivery of climate projects
• Clear expectations and boundaries with clients (including saying no when needed)
• High-quality documentation that can stand up to audit or regulatory review
• Cross-team alignment by sharing field insight and improvement ideas
• A professional and assertive client posture, even under pressure 💼

🌱 What success looks like in your first year

• You manage a portfolio of complex, multi-stakeholder clients with confidence
• You deliver high-quality GHG, LCA, SBTi, or CSRD-related projects on time
• Clients see you as a trusted advisor, not a technician
• You handle pressure, ambiguity, and conflicting expectations with resilience
• You contribute to improving tools, methods, templates, or processes
• You mentor newcomers or support internal initiatives as you grow 🤝

🌱 Skills to succeed

You’ll thrive in this role if you:

• Have 2–8 years of experience in consulting, project management, sustainability, climate/energy, engineering, or data-driven roles
• Are very comfortable with numbers, assumptions, and calculations
• Have strong project- and stakeholder-management skills 
• Communicate clearly and confidently, simplifying complex topics for non-experts
• Are assertive and comfortable pushing back when needed (scope, delays, data quality) 💬
• Are resilient to change: fast-moving environments, evolving products, multiple priorities
• Are curious about climate regulation and carbon accounting (GHG Protocol, SBTi, CSRD…)
• Are bilingual in French and English (C1/C1), both verbal and written ✨

You may also have:

• Strong Excel skills (mandatory)
• Experience with Python/SQL/BI tools (nice to have)
• Prior exposure to climate frameworks or sustainability consulting 📊

You might not be a fit if:

• You prefer working behind the scenes with minimal client interaction
• You dislike challenging clients or navigating conflicting opinions ❌
• You find fast-paced environments overwhelming

🌱 Perks & benefits

• 💰 €44-54K total annual compensation (incl. variable)


• 📍 Beautiful offices in the heart of Paris (9ᵉ arrondissement)


• 🏠 Flexible remote work options


• ⚒️ Top-notch tools to help you do your best work
