Trainee Asset Manager

Hartree Partners is a global merchant commodities firm specializing in energy and its associated industries. We focus on identifying value in the production, refinement, transportation and consumption of tradable commodities and anticipating opportunities in the supply chain where they may be under or over‑valued.

Founded originally as Hess Energy Trading Company LLC (HETCO) in 1997, Hartree has a global reach spanning 8 offices and approximately 75 traders and originators. The company’s rigorous research, analytical approach, and entrepreneurial culture have contributed to its strong track record and growth over that time.

Hartree Solutions is the physical business; we are a leading independent power generation business specialising in flexible gas peaking plants that provide essential balancing services to the UK electricity grid. With a growing portfolio of distributed generation assets across the UK, we play a vital role in supporting the UK’s transition to a low‑carbon energy system by delivering fast‑response, on‑demand power.
