Expert Battery System Engineer

Conteúdo do emprego

Vaar Systems is an ambitious and fast-growing startup on a mission to revolutionize marine propulsion with high-performance, clean energy systems. At Vaar, we don’t just build batteries—we engineer integrated energy solutions that electrify the future of marine transport.

We’re currently looking for a talented and driven Expert Battery System Engineer with a strong background in medium-voltage (MV) design to join our core MARINEPOWER development team. Based in our Andenne office, you will be part of a multi-disciplinary team developing one of the first fully integrated MV battery + converter systems for direct ship propulsion.

This is a unique opportunity to work at the frontier of marine electrification, help define the technical architecture of a next-generation battery system, and shape a fast-moving company from the inside.

Responsibilities:

As the lead engineer for MV battery design, you will be responsible for:

● Architecting and validating the electrical and physical design of a medium-voltage battery system for maritime applications (+5,000 VDC).

● Defining insulation, thermal protection, fault containment, and grounding strategies.

Conducting safety and failure mode analyses (FMEA, arc flash, etc.) in line with marine certification standards.

● Collaborating with BMS and converter engineers to ensure safe and reliable system-level operation.

● Selecting and qualifying cells and components that meet MV electrical and maritime mechanical requirements.

● Supporting lab integration, test planning, and type approval documentation (e.g., DNV, BV, ABS).

● Providing input into the manufacturing and industrialization plan for MV battery modules.

Qualifications:

● MSc or PhD in Electrical Engineering, Power Systems, or related discipline.

● Minimum 5 years of experience in high-voltage or medium-voltage energy storage systems

● Proven experience in battery module design, especially in high-reliability or safety-critical environments (marine, rail, aerospace, etc.).

● Familiarity with shipboard electrical architectures, maritime standards (IEC 60092, IEC 62485), and classification body requirements.

● Strong command of tools for electrical simulation CAD (SolidWorks/EPLAN), and safety analysis.

● Excellent analytical skills and a hands-on, solution-driven mindset.

● Strong communication skills in English & French

Bonus Points:

● Experience working with MMC converters or hybrid marine propulsion systems.

● Prior exposure to type approval processes for maritime or offshore systems.

● Experience with fire suppression, mechanical integration, and naval safety constraints.

Benefits:

● Competitive salary and benefits package.

● Bonus based on performance.

● Opportunity to work on cutting-edge battery technology.

● Collaborative, supportive, and fun work environment!

● Potential for professional growth and development.
