🌱  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 (2–5 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.

Based on your previous experience and performance during the application process, you will be selected for either the Scale or Professional Services team. Climate Experts in the Scale team focus on guiding customers through their climate journey, supported by the features and workflows available on the Greenly platform. Climate Experts in the Professional Services team work with more complex clients who require deeper project management, tailored support, and additional professional services.

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 2–5 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

• 💰 Salary package: €38.000 - €51.000 per year (total package, 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

• 🩺 Private medical insurance with Alan (including mental health support), 100% covered

• 🚅 50% Navigo reimbursement for public transport

• 🥗 Sustainable lunch vouchers via Ekip

• 🤸 Partial coverage of your Gymlib subscription

• 🤝 A culture of autonomy, transparency, and collaboration — with a team of highly talented, committed people

🌱 The recruitment process 

• Meet one of our Team Leaders for an introduction to the role

• Prepare and present a case study exercise to your future team

• Meet Ianis and/or Antoine, our Heads of Delivery

• Provide us with 2 references to complete the recruitment process

• We welcome you during our onboarding week! 🥳

We’re a team shaped by diverse experiences and ideas. If you’re excited about the role but don’t match every requirement, we still encourage you to apply — you may be the right person for the team. 🙏
