This role requires multidisciplinary expertise spanning mechanical design, electrical systems, and PLC/automation programming, with a strong automation mindset and advanced proficiency in risk management tools including Process FMEA (PFMEA), Machine FMEA, Assembly FMEA, Poka Yoke error-proofing, Risk Priority Number (RPN) management, and Control Plan governance. The incumbent operates in a challenging manufacturing environment characterized by unstructured legacy processes, outdated documentation, heavy manual handling operations, and budget and safety constraints that demand creative engineering solutions.ESSENTIAL DUTIES and/or RESPONSIBILITIES: Design, develop, and commission mechanical and automated equipment to eliminate manual heavy-handling operations in membrane manufacturing; apply DFM and DFS principles to produce safe, cost-effective, and maintainable solutions within defined capital budget constraints.Lead and facilitate Process FMEA (PFMEA), Machine FMEA, and Assembly FMEA sessions across new and existing manufacturing equipment and processes; assign Severity, Occurrence, and Detection ratings; calculate and manage Risk Priority Numbers (RPN); and drive corrective actions to target RPN thresholds prior to production release.Apply Poka Yoke (mistake-proofing) principles to equipment and process designs including fixture-based error-proofing, sensor interlocks, visual management systems, and assembly verification mechanisms to eliminate defect escape and ensure consistent product quality in membrane production operations.Develop, maintain, and govern Control Plans aligned with PFMEA outputs; define process control parameters, inspection frequency, measurement methods, and reaction plans; ensure Control Plans are sustained and updated as processes evolve.Program, configure, and troubleshoot PLC-based automation systems (Allen Bradley, Siemens, or equivalent), HMI interfaces, servo/stepper drives, pneumatic controls, and vision inspection systems to support new equipment commissioning and ongoing production reliability.Assess, document, and formalize legacy and underdeveloped process flows, SOPs, work instructions, and engineering standards; establish a structured documentation and engineering change control system to support process repeatability, operator training, and audit readiness.Conduct risk assessments including Job Hazard Analysis (JHA) and machine safety reviews for all new and modified equipment; ensure compliance with OSHA 29 CFR 1910, NFPA 70, ANSI B11 machine guarding standards, and Hydranautics EHS policies; integrate safety engineering controls (guarding, interlocks, E-stop systems) into all designs.Lead small cross-functional project teams (engineers, technicians, contractors) through full project lifecycle: scoping, design review, procurement, installation, qualification, and production handoff; manage project schedule and budget with regular status reporting to Engineering Director.Develop capital project business cases including ROI analysis, cost-benefit justification, and phased implementation plans for management approval; manage vendor quotes, contractor oversight, and procurement activities within approved budget frameworks.Partner with production, quality, maintenance, and EHS teams to resolve equipment reliability issues using structured root cause analysis methodologies (5-Why, Fishbone, DMAIC); implement and verify sustainable corrective and preventive actions.Other duties as assigned.SUPERVISORY RESPONSIBILITES:This position leads small project teams of 2–5 engineers, technicians, or contractors on a project basis. No direct supervisory authority over permanent headcount.MINIMUM EDUCATION and/or EXPERIENCE: Bachelor's degree in Mechanical Engineering, Mechatronics, Electrical Engineering, or a closely related engineering discipline and 8–12 years' experience in a manufacturing engineering or automation engineering role, or equivalent combination of education and experience.KNOWLEDGE, SKILLS and/or ABILITIES:Expert-level mechanical design proficiency using 3D CAD software (SolidWorks, AutoCAD, or equivalent); ability to produce and manage engineering drawings, GD&T specifications, tolerancing analysis, and BOM documentation for complex mechanical assemblies and automated systems.Hands-on electrical and controls engineering competency: panel wiring, PLC programming (Allen Bradley/Rockwell, Siemens, or equivalent), HMI configuration, servo and stepper drive commissioning, pneumatic system design, and sensor/vision system integration.Advanced mastery of FMEA methodologies: ability to independently lead and facilitate Process FMEA (PFMEA), Machine FMEA, and Assembly FMEA sessions; assign Severity, Occurrence, and Detection ratings; calculate RPN scores; prioritize and drive risk mitigation actions to defined target thresholds before production release.Expert application of Poka Yoke (mistake-proofing) design principles: fixture-based error-proofing, sensor-based detection and rejection interlocks, visual management and color-coding systems, and assembly verification mechanisms to prevent defect escape in membrane manufacturing operations.Proficiency in Control Plan development and ongoing governance: linking PFMEA outputs to process control parameters, measurement system requirements, inspection frequency, reaction plans, and SPC monitoring triggers; ability to train operators and technicians on Control Plan requirements.Strong working knowledge of Lean Manufacturing and Six Sigma tools including VSM, DMAIC, FMEA, 5S, SMED, and Kaizen facilitation; Six Sigma Green Belt certification or equivalent applied project experience required.Demonstrated ability to develop, formalize, and govern engineering documentation in legacy or underdeveloped environments: SOPs, work instructions, process flow diagrams, engineering change orders, and equipment qualification and validation records.Read and comprehend highly complex engineering specifications, regulatory standards, and technical documentation; write technical reports, engineering proposals, and capital justifications; effectively present recommendations to cross-functional stakeholders and management in one-on-one and group settings.Strong project management skills: ability to manage multiple concurrent engineering projects, vendor relationships, and contractor activities within approved budget and schedule; proficiency in MS Project or equivalent project management tools.Advanced Microsoft Office Suite skills (Word, Excel, PowerPoint, Outlook); working knowledge of ERP/MRP systems (JD Edwards or equivalent) for materials planning, requisition management, and project cost tracking.CERTIFICATES and/or LICENSES:Six Sigma Green Belt (required); Black Belt preferred. OSHA 30-Hour General Industry certification preferred. PLC Programming certification (Allen Bradley/Rockwell or Siemens equivalent) preferred.PHYSICAL DEMANDS and/or WORK ENVIRONMENT: (Typical physical demands and the work environment characteristics an employee must meet and encounter while performing the essential functions of the job. Reasonable accommodations may be made to enable individuals with disabilities to perform the essential functions.) Works in a manufacturing production floor environment with regular exposure to noise, chemical agents, moving automated equipment, and varying temperatures; appropriate PPE (safety glasses, gloves, steel-toed footwear, hearing protection) required in designated areas.Regularly required to stand, walk, and work on the production floor for extended periods during equipment installation, commissioning, troubleshooting, and operator training activities.Occasional lifting, pushing, or carrying of items up to 35 lbs during equipment setup, component handling, and inspection activities.Availability and willingness to travel to vendor sites, supplier facilities, or other Nitto Group locations domestically when required as part of equipment procurement, qualification, or business support activities.Must be able to work extended hours including evenings or weekends during critical equipment commissioning phases or production support events per the demands of the business.
