About Marbl

Marbl is pioneering the algorithmic flexibility trading layer to navigate the evolving electricity markets, characterized by increased volatility due to the rise of renewables, storage, and flexible demand. Our goal is to facilitate better trading decisions and execution to support a low-carbon power system. We are currently seeking a DevOps Engineer to lead our delivery infrastructure, ensuring the smooth operation of our algorithmic trading systems at scale.

About the Role

We are hiring a DevOps Engineer to design and own the delivery infrastructure that keeps our algorithmic systems running reliably at production scale.

As one of the first team members, you are joining us on a journey of building a company which makes its impact on the world by optimizing renewable assets, building forecasting engines for weather systems and energy markets, and helping to make renewable zero-emission energy sources even more competitive.

In the first year, you will be hands-on advancing our IT infrastructure, helping to set the systems up for scaling while staying performant and available, helping to build a team focused on quality, high availability, and reliable integration of our AI systems with energy markets and our partners and as the company grows you will have the choice start focusing on specific areas.

You will be deeply involved with happenings on the energy market, and exchange directly with the co-founders who have been in energy trading for decades to build the best, most efficient and low cost optimization system for renewable assets in Europe.
