Tech Lead (f/m/d) AI & APIs for energy and sustainability management

About the Role

Moving into a sustainable and carbon‑neutral future will require significant changes in the energy sector. Renewable energy and e‑mobility bring new challenges for the power grids of the future. Climate change is requiring us to save energy in buildings, factories, hospitals and data centers. At the same time, we need to ensure the longevity of electrical assets (transformers, switching cabinets, etc.) and increase their capacity to reduce asset investment needs. To do this, software products require strong data sources exposed via APIs, powerful AI forecasts and smart decisions/recommendations – packaged business capabilities. At Siemens Smart Infrastructure, our team of developers, data and AI experts and product managers are dedicated to advancing our products and driving sustainability.
