Senior Python Engineer

Gradyent is a Dutch climate technology company that develops a real-time Digital Twin Platform designed to optimize and decarbonize heating, cooling, steam, and CO₂ grids. By creating a dynamic digital replica of physical thermal energy networks, the platform enables grid operators to monitor, simulate, and optimize their systems from energy production through the network to end users, all in real time. The company serves district heating operators, industrial facilities, and utilities seeking to modernize their infrastructure and reduce operational costs.

About Gradyent 

Providing heating and cooling for homes, buildings, and industry accounts for nearly 50% of global final energy consumption. As these systems become increasingly interconnected with multiple energy carriers, their complexity will grow significantly. 

Traditional software is no longer sufficient to manage this level of complexity. This increases the need for digital and data-driven solutions to improve efficiency, enable smarter decision-making, and ensure reliable energy delivery. 

With our real-time Digital Twin Platform, we create a digital copy of the entire grid from production through distribution to end-users, combining geographical, weather, and sensor data with physics-based models and AI. It allows energy providers to optimise their systems in real time, improve operational control, and run simulations of future situations. 

Our team consists of 150+ energy specialists, engineers, data scientists and top-tier consulting alumni and is backed by investors Blue Earth Capital, SEB Greentech Venture Capital, Capricorn Partners, Eneco Ventures, Helen Ventures, and Energiiq.
