Climate Consultant / Project Manager (Sustainability Engineer)

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.

You are joining our Professional Services (PS) team, where you will manage our more complex accounts. Your role will focus on providing the deep project management, tailored support, and specialized services these clients need to succeed in their climate journey.

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

• 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

• 1–3 years of experience in consulting, project management, sustainability, climate/energy, engineering, or data-driven roles
• Very comfortable with numbers, assumptions, and calculations
• Strong project- and stakeholder-management skills
• Communicate clearly and confidently, simplifying complex topics for non-experts
• Assertive and comfortable pushing back when needed (scope, delays, data quality)
• Resilient to change: fast-moving environments, evolving products, multiple priorities
• Curious about climate regulation and carbon accounting (GHG Protocol, SBTi, CSRD)
• Bi-­lateral in French and English (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: €42,000 - €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
