• Bachelor\'s or Master\'s degree in Mechanical Engineering, Manufacturing Engineering, Industrial Engineering, Chemical Engineering, Materials Engineering, or a related technical discipline.
• 6+ years of experience in manufacturing engineering, process engineering, production engineering, equipment engineering, or a related industrial environment.
• Hands-on experience owning and improving complex manufacturing processes or production equipment.
• Strong experience with root-cause analysis, process optimization, equipment troubleshooting, and implementation of corrective and preventive engineering solutions.
• Experience specifying, commissioning, qualifying, and ramping manufacturing equipment or production systems from installation through stable operation.
• Ability to use production data, process capability, engineering experimentation, and structured problem-solving to drive measurable manufacturing improvements.
• Proficiency with engineering drawings, GD&T, CAD, equipment specifications, manufacturing documentation, and design-for-manufacturing principles.
• Proven ability to independently drive complex technical work from problem definition through implementation in a fast-moving manufacturing environment.
• Able to lift up to 50 lbs and wear a respirator for extended periods of time.

Responsibilities

• Own the technical performance and continuous improvement of critical manufacturing processes, driving improvements in throughput, yield, reliability, quality, safety, and cost.
• Lead the design, development, and implementation of tooling, fixtures, equipment modifications, and manufacturing systems to scale production capabilities.
• Diagnose complex equipment and process failures, lead root-cause investigations, and implement permanent corrective actions for long-term stability.
• Define manufacturing process requirements, operating windows, control strategies, and engineering standards to transition technologies to reliable production.
• Lead the specification, design review, installation, commissioning, qualification, and ramp-up of new production equipment and systems.
• Develop and execute engineering trials, process validation plans, and scale-up studies to reduce risk and establish repeatable methods.
• Use production data and process capability analysis to identify capacity constraints and prioritize improvements.
• Drive design-for-manufacturing decisions for new equipment and process technologies to improve scalability and maintainability.
• Serve as a technical resource on manufacturing engineering decisions, providing guidance on equipment design and troubleshooting.
