Design Engineering Expert

Overview

The Stationary Cell – Design Engineering role leads product design, engineering validation, and industrialization of lithium‑ion cells for stationary applications (ESS/utility, C&I, residential). The focus is on robust electrochemical design, safety and reliability, cost competitiveness, and seamless manufacturability.

Responsibilities and Duties

• Own the cell product design (format selection, capacity class, voltage window, separator and electrolyte selection) for stationary applications.
• Define electrode architecture (active materials, loading, porosity, thickness, density) and current collector specifications for long cycle life and high calendar life.
• Establish electrochemical performance targets (capacity, DCIR, rate capability, cycle/calendar life, safety) and acceptance criteria.
• Run design studies and DOE to optimize trade‑offs among energy density, life, safety, and cost; maintain design rules and golden parameters.
• Develop design documentation (PFDs, DFMEA, CTQs, drawings, BOMs) and interface control documents.
• Lead prototype builds and EVTs/DVTs/PVTs; plan test matrices, sample sizes, and statistical analysis of results.
• Define formation/aging recipes and grading criteria aligned to stationary duty cycles and storage profiles.
• Collaborate with Manufacturing Engineering to ensure design‑for‑manufacture (DFM), yield, and throughput on LFP/NMC lines.
• Partner with Quality for APQP/PPAP deliverables; ensure IATF/ISO/BIS/IEC compliance for stationary cells.
• Drive supplier qualification for materials (cathode/anode powders, binders, solvents, foils, separators, electrolytes) with incoming specs and change‑control.
• Lead safety engineering (abuse tests, nail/overcharge/thermal ramp) and support BMS interface requirements.
• Ensure cost targets via material selection, form factor optimization, and process simplification; maintain should‑cost models.
• Manage engineering change (ECN/ECR), configuration control, and lifecycle management for released designs.
• Coordinate customer qualification programs and technical responses; support field returns analysis and corrective actions.
• Mentor design engineers and collaborate cross‑functionally with R&D, Process Technology, Operations, O&M, and Supply Chain.

Basic Qualifications

• B.Tech/M.Tech in Chemical Engineering, Materials Science, Mechanical Engineering, or related discipline
• 12–18 years in lithium‑ion cell design engineering or advanced electrochemical product design.
• Minimum 5 years designing cells for stationary/ESS applications with proven industrialization outcomes.
• Hands‑on experience with APQP/PPAP, DFMEA/PFMEA, and validation testing for stationary duty cycles
• Electrochemical modeling, electrode/mechanical stack design, and separator/electrolyte selection.
• Design‑for‑manufacture (DFM), tolerance and stack‑up analysis, and CTQ/CTP control.
• DOE/SPC, statistical analysis, and reliability engineering (life modeling, calendar/cycle life).
• Safety engineering and standards familiarity (IEC, BIS, UL for ESS).
• Strong documentation, cross‑functional collaboration, and vendor interface skills

Role KPI

• Achievement of performance targets (capacity, DCIR, cycle/calendar life) for stationary cells.
• Design release on schedule with APQP/PPAP milestones met.
• First‑pass yield and Cpk of CTQs at mass production.
• Cost per kWh improvement through design optimization.
• Safety/abuse test pass rates and incident‑free qualification.
• Customer qualification success and reduced field returns..
