  • Work with quantitative developers, data scientists and trading teams to translate business challenges into practical analytical solutions.
  • Develop your understanding of the fundamentals of power, gas and LNG markets and their operational and commercial dynamics.

We are committed to meet the energy needs of a growing population and we are committed to the energy transition. The volatility of the energy trading markets requires excellence in risk management and a culture of innovation. We are fully embracing the digital revolution.
