Product Line Application Engineer – Custom Test Systems

The position is part of the Product Line organization and serves as the technical bridge between Product Management, R&D, Sales, and the field organization. It is neither a sales role nor a development role, but a customer-facing technical leadership position that ensures effective collaboration across all functions and translates application insights into successful products and solutions.

Key Responsibilities

• Support customers and internal teams with technical product questions, system sizing, configuration recommendations, and application-related inquiries.
• Assist in translating customer requirements into practical technical solutions and system concepts for a variety of power electronics applications.
• Contribute to customer-specific projects by helping define requirements, preparing technical documentation, and supporting solution development.
• Collaborate with Product Management, Engineering, Sales, and Service teams to address technical challenges and support successful project execution.
• Design, build, maintain, and deliver product demonstrations, proof-of-concept setups, and application-focused presentations for customers and industry events.
• Support the operation and continuous improvement of the applications laboratory, including test setups, equipment maintenance, safety procedures, and verification testing.
• Create and maintain application notes, technical documentation, training materials, and reference examples to support customers, sales teams, and partners.
• Assist with test automation, software integration, and industrial communication interfaces while supporting customer test systems and application environments.

Qualifications

• Degree in electrical engineering, power electronics, mechatronics or comparable.
• Several years in applications engineering, test engineering, commissioning or system integration — with genuine hands-on experience on high-power and high-voltage equipment (hundreds of volts and tens of kilowatts and above).
• Sound understanding of power electronics: converter topologies, regenerative/bidirectional operation, control loops and dynamic behavior, protection concepts, grid interaction and power quality.
• Practical knowledge of at least one target application field (battery test, e-mobility, energy storage, or data center / high-power DC distribution).
• Qualification and mindset for safe work on electrical installations (Elektrofachkraft or equivalent); willingness to take on responsible-person duties for the lab.
• Programming/scripting ability for test automation (Python or equivalent) and comfort with instrument remote-control interfaces.
• Ability to work customer-facing and to present technically to both engineers and decision makers.
• German and English, both business fluent.
