Mechanical Battery Engineer

Carrar is seeking a Product-Oriented Mechanical Engineer to lead the mechanical design and development of battery systems, from concept through production release. This role emphasizes robust, manufacturable design of battery modules and systems, and hands-on support through prototyping, validation, and industrialization. 

Location: Sderot, Israel (on-site, full-time)

Responsibilities

• Design and develop mechanical architectures for battery modules and systems, including enclosures, frames, compression systems, mounts, and safety features. 

• Own mechanical design from concept, detailed design, and prototyping through DVT/PVT and production release. 

• Define and manage mechanical requirements related to strength, vibration, shock, sealing, thermal interfaces, and serviceability. 

• Perform structural and fatigue analysis (FEA) to validate designs against automotive, marine, or industrial standards. 

• Collaborate closely with thermal, electrical, and systems engineers to ensure proper integration of cells, busbars, thermal systems, and electronics. 

• Support battery safety design, including mechanical protection, cell retention, venting paths, and abuse mitigation features. 

• Support prototype builds and root-cause analysis during testing and production ramp-up. 

• Generate and maintain detailed drawings, BOMs, and engineering documentation. 

Qualifications

• Bachelor’s or Master’s degree in Mechanical Engineering.

• 5+ years of experience in R&D roles in battery or energy storage systems. 

• Proficiency with CAD tools (SolidWorks, Creo, CATIA, or similar). 

• Experience with structural simulation tools (ANSYS, Abaqus, or equivalent). 

• Solid understanding of materials, fasteners, tolerances, and manufacturing processes (sheet metal, castings, extrusions, plastics). 

• Hands-on experience with prototype assembly and testing. 

• Ability to work in a fast-paced, product-driven environment with high ownership. 

Preferred Qualifications :

• Familiarity with battery system components and requirements: cells, modules, enclosures, etc. 

• Experience designing for environmental robustness (IP ratings, corrosion, vibration, shock).

• Knowledge of relevant standards (e.g., UN 38.3, IEC, ISO, automotive or marine requirements). 

• Experience working with suppliers and contract manufacturers. 

Personal Attributes :

• Strong sense of ownership and accountability for delivered hardware. 

• Practical, solution-oriented mindset with attention to detail. 

• Comfortable balancing performance, cost, and schedule trade-offs. 

• Clear communicator who works effectively across disciplines.
