Responsibilities

Lead a portfolio of complex, cross-functional Black Belt projects from charter through control, delivering committed financial and operational benefits
Apply the DMAIC methodology rigorously: define problem and scope, validate measurement systems, analyze root cause with statistical evidence, pilot and implement solutions, and establish sustainable controls
Partner with site and functional leadership to identify, scope, prioritize, and charter improvement opportunities aligned to business objectives
Manage project scope, timeline, resources, and risks; escalate barriers and report status to the Vice President, Operational Excellence and site leadership
Quantify and validate project benefits with Finance, tracking hard savings, cost avoidance, and capacity gains through realization
Perform advanced statistical analysis including capability studies, DOE, MSA/Gage R&R, hypothesis testing, regression, and control charting to drive fact-based decisions
Design and deploy statistical process control for critical process parameters and quality attributes, establishing limits, monitoring plans, and reaction rules
Lead structured root cause investigations for chronic yield loss, downtime, rework, scrap, right-first-time failures, and repeat deviations
Build and maintain operational dashboards and metrics — OEE, throughput, yield, RFT, changeover time, cost per unit — to expose performance gaps and improvement opportunities
Facilitate value stream mapping, kaizen events, and rapid improvement workshops across manufacturing, packaging, warehouse, and laboratory value streams
Deploy Lean tools including 5S, standard work, SMED/changeover reduction, TPM, visual management, and material flow optimization
Support development and sustainment of the site's daily management system, tiered accountability meetings, and problem-solving routines
Drive waste elimination and cycle time reduction while protecting product quality, compliance, and patient safety
Identify, scope, and lead improvement projects that leverage computer systems and digital tools to eliminate manual processes, reduce transcription error, and improve data availability across operations
