A Snapshot of Your Day

Join Siemens Energy as a Design Engineer for Medium Voltage Transformer Stations and shape the future of energy infrastructure. You’ll design and optimize both prefabricated and site-built MV/LV substations for utilities, industry, and data centers—ensuring every solution meets international standards and exceeds customer expectations. Imagine your detailed single line diagrams, protection schemes, and cable layouts powering critical infrastructure and supporting the general energy transition.



You’ll collaborate with sales, project management, and manufacturing teams to deliver reliable, cost-efficient and scalable transformer stations. Step into a role where your designs drive innovation, sustainability and customer satisfaction every day.

How You’ll Make an Impact
- Design MV/LV transformer stations (10–36 kV / 0.4–1 kV), preparing single line diagrams, protection schemes, and cable layouts.
- Specify key components like power transformers, MV switchgear (AIS/GIS/RMU), and LV switchboards, performing load flow, short-circuit, and voltage drop calculations.
- Optimize layouts for footprint, cooling, accessibility, and safety, integrating enclosures, cable entry systems, and fire protection.
- Ensure compliance with IEC standards, local grid codes, and support certification and type testing.
- You collaborate with sales, project management, and suppliers, reviewing drawings,
