Role Overview We are seeking a detail-oriented and technically robust Lithium Battery Assembly Engineer to lead, optimize and ensure the quality of the assembly process of lithium battery modules and packs. The role involves hands-on engineering work, process design, quality control, collaboration with R&D, and continuous improvement.

Key Responsibilities :

• Design, develop, and document assembly processes for lithium battery cells, modules, and packs, ensuring they meet safety, performance, and manufacturing efficiency criteria.
• Develop/implement Standard Operating Procedures (SOPs), Work Instructions, process flow charts, and assembly jigs/fixtures.
• Oversee and optimize cell interconnection (welding / tabbing), module assembly, module testing, pack integration, battery management system (BMS) integration.
• Select appropriate materials, adhesives, insulators, cooling mechanisms; ensure all components used are compliant with relevant safety and quality standards.
• Conduct risk analysis (e.g. thermal runaway, mechanical stresses, electrical stability) and incorporate mitigation methods in assembly design.
• Monitor and improve assembly yields; troubleshoot manufacturing defects or failures; perform root cause analysis and corrective/preventive actions.
• Collaborate with R&D, quality engineering, procurement, supply chain, and testing teams to validate prototypes, test batches, and scale up to mass production.
• Ensure compliance with regulatory & safety standards (UN-38.3, IEC 62133, UL, etc.), environmental and health & safety norms.
• Maintain documentation for traceability (batch history, component sourcing, manufacturing parameters).
• Train assembly operators, oversee shop floor implementation of processes, ensure hygiene, safety, and clean room / controlled environment protocols (if applicable).
• Continuously evaluate new tools, equipment, technologies, and assembly methodologies to improve cost, time, safety, and product performance.
• Required Qualifications & Skills Bachelor’s degree (or higher) in Electrical Engineering, Chemical Engineering, Materials Science, Mechanical Engineering, or a related field.
• Prior experience (1+ years) in lithium battery assembly / manufacturing / energy storage systems.
• Strong knowledge of lithium battery technologies (cell types, chemistry, form factors), battery module/pack architecture.
• Hands-on experience with welding/tabbing, spot welding / laser welding, ultrasonic welding, sealing, potting, adhesives, insulation materials.
• Understanding of BMS (Battery Management System) integration, test & measurement equipment.
• Proficiency in drafting SOPs, process documentation, and quality tools like FMEA, root cause analysis, statistical process control.
• Familiar with safety / regulatory standards relevant to lithium batteries (IEC, UL, UN38.3, etc.).
• Familiarity with clean room / controlled environment assembly, hazard assessment, safe handling of chemicals / cells.
• Strong problem-solving skills; attention to detail.
• Good communication skills; ability to coordinate among cross-functional teams.
• Desirable Attributes Experience scaling from prototype to high volume production.
• Experience using automated / semi-automated assembly equipment.
• Knowledge of thermal management, mechanical enclosure design.
• Familiarity with quality certification processes (ISO 9001, ISO 14001, etc.).
• Lean manufacturing / Six Sigma or similar continuous improvement experience.
• Performance Metrics Yield rate of battery modules / packs (defect / failure rates)
• Assembly throughput (units per time) and production cycle time reductions
• Safety compliance record (zero safety/quality incidents)
• Time to scale up new designs from prototype to production
• Cost per unit (material, labour, tooling) improvements
• Reporting & Collaboration Reports to: Head of Manufacturing / Operations / Engineering (depending on org structure)
• Works closely with: R&D Engineering, Quality Assurance, Supply Chain / Procurement, Production / Shop Floor, Safety / EHS
• What We Offer Competitive salary & performance incentives
• Opportunity to work on cutting edge energy storage technologies
• Involvement in end-to-end product lifecycle: from concept to production
• Learning and development opportunities (technical training, certifications)
• A collaborative, innovation-driven work environment
