Quantitative Research

Engelhart was founded in 2013 by BTG Pactual Group as a commodities trading company. Our business model is "asset light" and highly diversified – giving us the ability to adapt effectively and nimbly to changing market conditions. We have assembled successful multidisciplinary teams, leveraging advanced fundamental analysis with deep quantitative and weather research capabilities. Our activities are underpinned by strong risk management practices and by powerful technology and operational excellence. We have exceptional teams with diverse global backgrounds and decades of experience, and are driven by a highly collaborative culture, across products and competencies.

In 2024, Engelhart acquired Trailstone, a global energy trading and technology company. The acquisition provides us with new expertise, analytics and proprietary technology which is being used to provide risk management and optimisation services to help maximise the value of our clients' renewable power. The acquisition also expanded Engelhart's capabilities into physical natural gas across North America, a critical fuel to support the energy transition.

Our talented and experienced individuals work together according to its four company values: be bold, be collaborative, be proactive, be your best.

Six-Month Internship Program – Grenoble, France (on-site)

Start Date: 17 February 2026

About the Internship

We are offering three full-time internship opportunities in Grenoble beginning February 2026:

• Two positions in Renewable Portfolio Analytics.
• One position in Quantitative Research.

Our Grenoble office is a small, talent-rich hub, home to a highly skilled and experienced team. Our close-knit environment provides interns with an opportunity to build meaningful, hands-on mentorship relationships with specialists across the business.

All three internships share a common foundation: practical experience, exposure to real-world business challenges, and the opportunity to collaborate with skilled professionals in a supportive environment.

Eligibility: You must be enrolled at a French university or Grande École and able to obtain a convention de stage for a six-month internship starting February 2026.

If you don't meet the French convention de stage requirements, please keep an eye out for our 2026 internship opportunities in Berlin, Geneva, London and the US, which will open in the coming weeks. Follow us on LinkedIn to be the first to hear when applications go live.
