Demonstrated ownership of large-scale process improvement, capital equipment, automation, factory expansion, or manufacturing transfer projects.
Strong experience with equipment implementation, troubleshooting, process validation, SPC, PFMEA, yield improvement, and structured root cause analysis.
Working knowledge of ERP/MRP systems, change control processes, and data analysis tools such as Excel, JMP, or Minitab.
Lean manufacturing and Six Sigma experience required.
Strong written and verbal communication skills, including the ability to influence cross-functional teams, train operations personnel, and present recommendations to leadership.

Nice To Haves

Familiarity with Oracle, Agile, or similar systems is preferred.
Green Belt or Black Belt certification strongly preferred.

Responsibilities

Lead manufacturing engineering initiatives that improve safety, quality, yield, throughput, cost, and overall operational performance across existing and future production lines.
Own or co-lead capital projects tied to plant growth, including line expansion, equipment scoping, vendor selection, specification development, purchasing support, installation planning, commissioning, and production ramp-up.
Define manufacturing process requirements for new equipment and new lines, ensuring readiness for capacity, process capability, ergonomics, safety, maintainability, and operator usability.
Drive root cause analysis and corrective action for process, equipment, and yield issues using structured problem-solving methods and data-driven decision making.
Partner with Product and Process Engineering to support transfer to production, and design-for-manufacturability improvements.
Lead or support validation activities including IQ, OQ, and PQ for new equipment, new processes, and significant process changes.
Develop and standardize manufacturing documentation including work instructions, SOPs, PFMEAs, control plans, process flows, validation protocols, and training materials.
Establish process monitoring methods, SPC approaches, and yield dashboards to identify opportunities for continuous improvement and sustain gains over time.
Coordinate engineering changes and process changes to minimize production disruption, scrap risk, and impact to customer delivery commitments.
Collaborate with Maintenance and Quality to define preventive maintenance, calibration, spare parts, and equipment control strategies for critical production assets.
Work with Supply Chain and external suppliers to manage technical requirements, equipment build progress, FAT/SAT support, installation readiness, and issue resolution.
Mentor junior engineers, technicians, and operations personnel while helping build a strong continuous improvement culture across the site.
Serve as a key engineering voice in capacity planning, factory layout discussions, and long-range manufacturing strategy.
