Battery System Architect (m/f/d)

To strengthen our ESS team at our Dornbirn location, we are looking for a technically skilled professional who will be independently responsible for our system architecture for stationary battery storage systems, from design through to commissioning.

• System architecture and design of battery storage systems, including inverter technology and transformer stations
• Preparation of single-line diagrams, circuit diagrams, and protection concepts for low-voltage, medium-voltage, and high-voltage connections
• Definition of the network and communication architecture, including integration with the energy management system (EMS) and SCADA
• Coordination of the various trades involved and interface management
• Support for Factory and Site Acceptance Tests (FAT/SAT)
• Commissioning and service calls directly at the customer’s site
• Professional guidance and mentoring for younger team members

What you bring with you:

• Solid knowledge of electrical engineering and control panel construction (a college degree or technical college diploma is preferred)
• Several years of experience (ideally 3+ years) in plant engineering, energy supply, or electrical power distribution
• Experience with medium-voltage technology and the wiring of low-, medium-, and high-voltage systems
• Familiar with the technical connection regulations for low voltage (VDE-AR-N 4100) and medium voltage (VDE-AR-N 4110)
• Expertise in inverter technology, battery storage, and renewable energy
• Proficiency in using CAD/E-CAD tools (e.g., EPLAN, AutoCAD Electrical)
• Proficiency in German and English, as well as a willingness to travel within the DACH region
• A structured, solution-oriented approach to work and a passion for teamwork

This is what we offer you:

• Responsibility for challenging large-scale projects from day one

• The freedom to actively shape architecture and processes
• Flexible working hours (as long as project and service assignments allow)
• A friendly, close-knit team with a flat organizational structure
• Competitive salary, with a willingness to pay above market rate depending on qualifications and experience
