Battery System Engineer, 100% (m/w/d)

ABOUT THE COMPANY

Backed by significant funding, and with teams across Germany and Switzerland, we are partnering with global and European industry leaders to become the category-defining AI Operating System for engineering companies.

ABOUT THE ROLE

This includes leading end-to-end battery pack architecture, hands-on prototype assembly, and data-driven validation workflows. This role demands strong hardware engineering fundamentals, practical lab experience, and analytical curiosity. We are offering more than a job, it is an opportunity to help shape the next generation of battery engineering.

• Lead the end-to-end design and architecture of compact, high-demanding battery packs tailored for non-automotive applications such as robotics, eVTOLs, or other specialized industrial systems.
• Build, assemble, and iterate on small-scale battery pack prototypes hands-on in our lab, ensuring mechanical, electrical, and thermal reliability.
• Design and execute system-level testing and validation protocols to evaluate performance, safety, and durability under real-world operating conditions.
• Analyze test and operational battery data using Python to extract actionable insights, validate models, and drive continuous design improvements.

• Degree in Electrical Engineering, Mechanical Engineering, Materials Science, Energy Systems, or a related technical field with proven industry experience in battery pack design.
• Demonstrated track record in designing compact, high-performance battery packs for demanding applications (e.g., robotics, aerospace/eVTOL, or specialized mobility).
• Hands-on experience in building and assembling battery pack prototypes, including cell selection, mechanical integration, thermal management, and safety considerations.
• Solid background in system-level battery testing and validation workflows, with the ability to troubleshoot hardware and interpret complex test results.
• Strong data analytics skills, particularly in Python, for processing battery test data and collaborating effectively with AI and simulation engineers.
• Fluent in English; German language skills are strongly preferred.

• A high-impact, hands-on engineering role with real responsibility and room for initiative
• The opportunity to drive leading technology solutions in real-world applications
• A collaborative and dynamic work environment that values vision and impact
• High impact by actively contributing to the company's growth
• Flexible working hours and hybrid work models
