• Partner with Quality teams to sustain and continuously improve quality performance metrics and manufacturing outcomes.
• Lead and/or support structured problem-solving initiatives utilizing proven methodologies to identify root causes and implement corrective actions.
• Ensure adherence to Quality Management System (QMS) requirements, audit standards, calibration processes, and product traceability requirements.
• Support full compliance with Lockout/Tagout (LOTO), Personal Protective Equipment (PPE), machine guarding requirements, and safe operating procedures.
• Proactively identify, assess, and mitigate safety risks associated with cylinder block production, industrial chemicals, material handling, lifting operations, and ergonomic factors.
• Foster a strong safety culture through Near Miss reporting, Job Safety Analyses (JSAs), risk assessments, and continuous safety improvement initiatives.
• May oversee a small team of hourly associates and/or provide guidance and direction to Student Workers (STW) and interns.
• Deliver technical coaching, mentorship, and operational support to operators and technicians during shift operations.
• Drive machining optimization efforts through the evaluation and improvement of tooling, cutting parameters, CNC programs, consumables, and manufacturing processes.
• Implement approved cost reduction, productivity enhancement, and operational improvement initiatives.
• Lead and/or support productivity improvement projects focused on efficiency, quality, and cost performance.
• Support New Product Introduction (NPI) activities, product launches, and engineering change implementation as needed.
• Collaborate effectively with Operations, Maintenance, Quality, Engineering, and Health, Safety, and Environment (HSE) teams to achieve business objectives.
• Lead small cross-functional teams in structured problem-solving, continuous improvement, and operational excellence initiatives.
• Communicate effectively across all levels of the organization utilizing clear, professional, and adaptable communication styles.
• Support customer visits, audits, assessments, and plant tours as required.
• Demonstrate strong hands-on machining expertise, with experience in cylinder block, cylinder head, or other large component machining considered advantageous.
