• 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.
• Possess in-depth knowledge of cutting tools, cutting parameters, machining processes, and tool life optimization strategies.
• Exhibit strong analytical thinking, problem-solving capabilities, and a results-oriented approach with a focus on execution.
• Demonstrate CNC programming and operational proficiency, including G-code and M-code; experience with 3-axis CNC machines is preferred, while Siemens 840D SL experience is advantageous.
• Apply the ability to read and interpret technical drawings, Geometric Dimensioning and Tolerancing (GD&T), and datum structures.
• Utilize precision measurement and metrology tools, including micrometers, calipers, indicators, and other inspection equipment, with the ability to interpret Coordinate Measuring Machine (CMM) reports.
• Demonstrate expertise in machine setup and tooling, including fixture setup, tool changes, tool offsets, and establishing accurate touch-off points.

To be successful in this role, you will need the following: 

• Strong manufacturing and machining expertise to interpret drawings, select materials and tooling, program machines, and implement equipment and process changes that improve quality, cost, and operational performance.
• Commitment to health, safety, and compliance by applying machine guarding standards, dimensional metrology, and safe work practices to create a reliable, injury‑free manufacturing environment.
• Process discipline and technical rigor to design measurement systems, document standardized manufacturing procedures, and ensure consistent execution across equipment, processes, and stakeholders.
• Effective collaboration, communication, and problem‑solving skills to work cross‑functionally, leverage diverse perspectives, make sound decisions, and drive continuous improvement results.
