Electrical Integration Engineer / Elektrokonstrukteur - BESS (m/f/d)

Your Role

We are looking for an Electrical Integration Engineer / Elektrokonstrukteur (m/f/d) to support the development of our containerized Battery Energy Storage System (BESS) platform. You will focus on electrical documentation, switching cabinet design, cable routing, and the interface between ECAD and mechanical design , helping ensure a smooth workflow from EPLAN through SolidWorks Electrical into SolidWorks Mechanical .

You will work closely with the mechanical team, system engineering, and others to deliver robust, implementation-ready design data and integration concepts. The role is part of the BESS development team and supports system integration within STABL’s BESS architecture, including STABL’s multilevel inverter technology .

Your mission

• Create, maintain, and improve electrical schematics, wiring documentation, and design packages in EPLAN for BESS products and subsystems.
• Support the design and layout of switching cabinets / electrical cabinets , including component arrangement, wiring concepts, and implementation-ready documentation.
• Support the integration workflow from EPLAN through SolidWorks Electrical into SolidWorks Mechanical , ensuring consistent and usable design data across disciplines.
• Define and coordinate the electrical-mechanical interface , including connection points, installation requirements, space claims, and integration constraints.
• Develop and optimize cable routing, cable packaging, and installation concepts within containerized BESS systems.
• Support the definition and integration of cables, connectors, fuses, protective devices, and related electrical hardware .
• Work closely with the mechanical engineering team to ensure that electrical design inputs are correctly transferred into the mechanical environment.
• Support design iterations, prototype implementation, and product improvement by resolving practical integration issues between electrical and mechanical design.
• Contribute to documentation quality, engineering standards, and efficient handover into prototype build and industrialization.

Note: This role is focused on in-house product development and integration within the BESS platform.

Your profile

• Engineering degree in Electrical Engineering, Mechatronics, Mechanical Engineering , or a similar technical field.
• 3–8 years of experience in a related technical field such as ECAD design, electromechanical integration, switching cabinet design, electrical design, or product development of complex technical systems .
• Strong hands-on experience with EPLAN and experience working with SolidWorks Electrical in an interdisciplinary engineering environment.
• Good understanding of switching cabinet / electrical cabinet design , electrical documentation, and implementation-oriented design.
• Good understanding of the interface between ECAD and mechanical design , ideally including collaboration with SolidWorks Mechanical workflows.
• Experience with cable routing, electrical packaging, and electrical/mechanical interface definition .
• Structured and pragmatic working style with the ability to coordinate across multiple technical disciplines.
• Experience in industrial equipment, energy systems, machinery, switchgear, or other complex engineered products is beneficial.
• Knowledge of EU Low Voltage Directive (2014/35/EU) compliance and application of harmonized standards/documentation for CE conformity; familiarity with relevant VDE/DIN EN standards for low-voltage switchgear/controlgear assemblies and machine/control panel electrical equipment (e.g. DIN EN IEC 61439-1/-2 (VDE 0660-600-1/-2) , DIN VDE 0100 (low-voltage installations) , DIN EN 60204-1 (VDE 0113-1) electrical equipment of machines , DIN EN IEC 60664-1 (VDE 0110-1) insulation coordination ; EN/IEC 61140 protection against electric shock ).
