Sr Cell Design Engineer

We are seeking a Product Design Engineer with deep experience in pouch cell design, productization, and manufacturing scale‑up to lead the mechanical design and integration of next‑generation pouch battery systems. This role will own cell architecture, engineering drawings, and BOM strategy from concept through pilot and production. The ideal candidate will bring strong technical leadership, cross‑functional influence, and hands‑on battery design expertise to deliver robust, scalable, and high‑performance products.

• Lead design and release of pouch cell assembly drawings, specifications, CAD models, and BOMs
• Own electrode layout, stack architecture, and mechanical containment design
• Drive design‑for‑manufacturability and scale‑up readiness
• Lead DFMEA/PFMEA, tolerance stack‑up, and engineering change management
• Resolve complex assembly and integration challenges (tabs, sealing, electrolyte distribution, swelling)
• Translate manufacturability into robust design rules
• Lead DOE planning and statistical analysis to optimize performance
• Establish in‑process quality control and inspection criteria
• Drive root‑cause analysis and corrective actions
• Collaborate cross‑functionally with manufacturing, quality, and supply chain
• Support supplier technical reviews and cost reduction initiatives
• Mentor junior engineers and provide technical leadership

• MSc in Mechanical Engineering, Chemical Engineering, Materials Science, or related field
