We have a truly global team!

Our people come from more than 23 different countries from all over the world. Through our differences, innovative ideas are born to challenge the status quo and redefine the future of energy trading.

At Cobblestone Energy, we have a flat organisational structure. We avoid formal hierarchy except where it is essential for business control and good governance. Candour is essential and we value rigorous debate. Decisions are made quickly and rooted in responsibility.

Chief Technology Officer

We don’t artificially manage and create a diverse and inclusive workplace. We just are. While our people come from more than 23 different nationalities we don’t apply superficial labels to them. We see diversity as the broad range of life experiences, opinions, thought processes and unique set of perspectives we bring to every aspect of our business. We focus on talent and strong cultural compatibility, recognizing that this can come from anyone from anywhere.
