Description du poste

About Weastem – Finance x Strategies for the New Climate Era

Weastem is a finance & strategy firm for the New Climate Era. We support financial institutions, asset managers, private equity firms, and corporates across Europe to navigate systemic risks, climate disruption, and emerging sustainability mandates. Founded in 2025 in Paris, as the spin-off of a seasoned team with a strong track record and a recognized expertise, we are a growing ecosystem of 20+ professionals located at the intersection of strategy, finance, and sustainability. We hold one conviction: finance must shift from being a lever of extraction to a force of transformation rooted in long-term value, resilience, and responsibility.

Our ambition is clear

→ Help shift the economy from an extractive model to a regenerative one — by positioning finance as a strategic accelerator of that transition.

This Translates Into

• Developing strategies and frameworks that move beyond compliance into transformation
• Cultivating systemic thinking and cross-sector collaboration
• Training the next generation of finance professionals to work with purpose and vision
  
  

Weastem is expanding — and we are currently seeking our next intern, ready to play a key role in delivering and shaping missions that matter.

Your mission

As a Strategy & Sustainability consultant, you will be an integral part of our consulting teams — not an observer, but a contributor. Under the guidance of experienced consultants and managers, you will gain firsthand exposure to how finance, strategy, and sustainability intersect through real client work.

You Will

• Contribute to client engagements under the supervision of consultants and managers
• Conduct research on ESG regulations, climate and biodiversity dynamics, and market trends
• Support the preparation of client deliverables such as benchmarks, analyses, interview guides, and presentations
• Assist in structuring methodologies for sustainability assessments and impact measurement
• Participate in internal knowledge development and knowledge-sharing initiatives
• Contribute to the internal develpment of the Team, such as organizing events or implement new tools
  
  

To ensure your learning and development, you will be supervised and coached with regular feedback, and your work will evolve as your skills grow. Our goal is to help you become a thoughtful, rigorous and impact-driven professional.

Core Types of Missions You Might Support

• Strategic ESG / sustainability due diligence
• Portfolio risk & resilience analysis (climate, biodiversity, social dynamics)
• Design of adaptation, climate, and regenerative finance strategies
• Transformation roadmaps for financial and non-financial institutions
• Development of investment methodologies that embed sustainability into value creation
• Direct support to portfolio companies through GHG emissions assessments, risk analyses, tranings and other customised missions.
  
  

What We Look For

We are looking for students or recent graduates with intellectual curiosity, strategic thinking, and a desire to contribute to meaningful work.

You Are

• a student or recent graduate with a background or clear interest in finance, economics, strategy, or sustainability
• A dynamic candidate who brings curiosity, analytical rigor, research skills—and the ability to synthesize complex information
• A quick learner who enjoys problem-solving and teamwork
• Passionate about sustainability
• Motivated to explore the role finance can play in shaping a sustainable, regenerative economy
• Willing to engage not just in project work, but also in building Weastem’s collective knowledge and internal culture
• Communicates clearly in English and ideally French (advanced level necessary); other European languages are a plus
  
  

What You'll Find At Weastem

• A collective working environment where every voice matters — combining a core team and independent partners into a living ecosystem
• A structured and supportive onboarding and mentoring process
• Exposure to intellectually rich, cross-sector challenges that require both thoughtful rigor and courage to act
• Support for learning, growth, and inquiry — regular internal reflections, training, mentorship
• A values-driven culture anchored in collaboration, integrity, courage, and systems thinking
• A central Paris office in the 9th arrondisement
• A paid internship (1800€/month), with access to all team activities and shared resources
