You Will:

• Design, develop and validate manufacturing processes for the underbody assembly line (front, rear, center and complete) structures.
• Ensure robust process flow, proper cell layout and ergonomic work design.
• Define and optimize welding parameters, gun selection and robot path programming coordination.
• Continuously improve cycle time, process stability and repeatability through data driven analysis.
• Ensure all process documentation (PFMEA, Control Plans, Standard Work, Process Flows) is complete and production ready.
• Coordinate build events, trial runs, and quality audits to confirm process and product stability.
• Collaborate with Operations, ME, and Quality to verify line readiness and address early build issues.
• Specify and approve tooling, jigs, fixtures and welding guns for the underbody line.
• Collaborate with suppliers and tooling engineers during design reviews and buyoffs.
• Support installation and commissioning of new equipment and tooling.
• Maintain equipment documentation and process standards (layout, sequence of operations, torque charts, etc.).
• Define and maintain process parameters to meet dimensional and weld quality requirements.
• Analyze production data to identify process deviations, perform root cause analysis and implement corrective actions.
• Apply lean manufacturing and six sigma methodologies to drive continuous improvement initiatives.
• Capture lessons learned from launches and incorporate them into future programs.
• Ensure process compliance with BIW standards and customer requirements.
• Implement error-proofing solutions and automation enhancements.
• Optimize line balancing to improve throughput and resource utilization.
• Work closely with maintenance, production, quality and automation teams to ensure smooth operation of the underbody line.
• Support daily production meetings and provide process feedback.
• Train production and maintenance personnel on process changes and standard work.
• Interface with product engineering for manufacturability reviews (DFM/DFA).
