Data Scientist – Power Markets M/F – Paris

At Qair, we have chosen an organization that promotes versatility among our employees and allows the company to constantly adapt to market needs.

Our corporate culture is inspired by the entrepreneurial spirit that has driven Qair since its inception. Far from traditional hierarchical management, we encourage initiative and autonomy, fostering an environment conducive to innovation and creativity.

We are an independent renewable energy company. Our 800 employees operate and build over 1.7 GW of assets in the 20 countries where we are present and are developing a pipeline of more than 35 GW.

Our culture, based on trust and mutual respect, allows our employees to thrive professionally and actively contribute to the company's success. By unleashing the potential of each individual, we boost collective performance and equip ourselves to meet the challenges of a constantly evolving market.

You will join Qair's Energy Management team, which is developing a new sales and trading activity on electricity markets. At the intersection of data, renewable asset optimization, and trading, the team drives the valuation of multi-technology portfolios (solar, wind, storage) and supports the evolution of Qair's energy model toward a more integrated, market-driven approach.

As a Data Scientist – Power Markets, you will contribute to building forecasting models, analytical tools, and market analyses that support Qair's activities in the energy markets. This role offers hands-on immersion in how electricity markets function, as well as the opportunity to apply quantitative methods to real operational challenges.

The position is based in Paris, with no travel required. Following the end of the trial period, a planned on-call arrangement will be implemented, involving one Saturday and one Sunday per month, with equivalent compensation.

You are looking for a stimulating and empowering challenge, where innovation is rewarded?

Join us and unleash your potential!
