Digital Twin Engineer

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 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. What we’re looking for You’ll join our Digital Twin team, consisting of software engineers, digital twin engineers, and data analysts. We’re at the intersection of software development and engineering, aiming to maximize our sustainable impact through our SaaS platform. You’ll be working on a layer of intelligence (a combination of physics, mathematics, and machine learning) that simulates, analyses, and optimizes heat networks. You’ll be tasked with building generalized software that can be configured by our colleagues in the Customer Solutions & Operations team. You’ll focus on improving our models, control strategies, parameter estimation, and optimization strategies. Our high-level stack Python, GCP, UbiOps, DuckDB, MongoDB, Parquet, Polars. What you'll be doing Develop a deep understanding of the hydraulic and thermodynamic behaviour of heating systems and translate this knowledge into scalable software solutions. Design, build and optimise high-performance Python applications where efficiency, reliability and maintainability are critical. Apply and extend our digital twin technology across innovative, state-of-the-art projects. Drive research and development initiatives, exploring new ideas and transforming them into practical product features. Collaborate closely with software engineers, solution engineers and domain experts to deliver robust, high-quality solutions. Take ownership of your work, planning and managing your tasks independently and, where appropriate, leading the development of a product component.
