The Senior Manufacturing Engineer drives improvements in complex manufacturing processes to achieve safety, quality, delivery, and cost goals, while providing technical leadership and cross-functional support.

• Own assigned manufacturing processes/value streams, acting as the primary technical contact for production issues, non‑conformances, and process questions.
• Monitor process performance (scrap, rework, OEE, throughput, changeover time, labor productivity) and drive corrective actions when performance deviates from target.
• Lead structured problem solving (5‑Why, Fishbone, DMAIC, PDCA) to address chronic issues in safety, quality, delivery, and cost.
• Support operators and technicians with clear standard work, work instructions, and training.

• Lead capital equipment projects from concept through validation: requirements definition, vendor selection, design reviews, FAT/SAT, installation, and production ramp.
• Develop and execute equipment validation plans (process capability, gauge checks, safety, and reliability) to ensure readiness for production use.
• Design, specify, or improve tooling, fixtures, and gaging to enhance throughput, ergonomics, quality, and ease of use.
• Partner with Maintenance on preventive maintenance (PM) plans, critical spares strategies, and equipment reliability improvements.
• Identify, prioritize, and lead continuous improvement projects that reduce scrap, improve yield, increase capacity, and reduce conversion cost.
• Champion Lean manufacturing principles (5S/6S, visual management, standard work, flow, pull, SMED, error‑proofing) within assigned areas.
• Evaluate and deploy automation and digital solutions (e.g., robotics/cobots, automated inspection, data collection, SCADA/MES, AMRs) where they provide clear safety, quality, or cost benefits.
• Develop robust business cases (benefits, CAPEX, payback, IRR) and track realized savings.

• Support New Product Introduction (NPI) and transfers by defining manufacturable processes, layouts, and equipment for new designs.
• Participate in or lead PFMEA, Control Plan, and process capability work for new or changed processes.
• Own engineering changes (ECR/ECO) impacting manufacturing, ensuring risk is understood and changes are implemented with appropriate validation, documentation, and training.

• Partner with Quality to ensure processes consistently meet internal specifications, customer requirements, and agency/industry standards.
• Support root cause and corrective actions (RCCA/CAPA) for internal and customer issues, including documentation and communication.
• Ensure equipment, processes, and documentation comply with relevant safety, regulatory, and audit requirements (e.g., machine guarding, LOTO, calibration, record retention).

• Strong knowledge of manufacturing processes and methods relevant to the site (e.g., machining, welding, assembly, thermal processes, testing, automation, vision systems).
• Proficient in engineering tools such as CAD, GD&T, statistical analysis (SPC, capability), and basic programming/configuration for relevant controls or data systems.
• Working knowledge of industrial electrical and controls systems (PLCs, HMIs, VFDs, safety circuits, sensors) sufficient to specify requirements, review designs, and support troubleshooting with Maintenance, vendors, or controls specialists.
• Demonstrated ability to plan, validate, and sustain robust manufacturing…
