Manager Simulation Modeler Engineer

Johnson & Johnson • Raritan, NJ

12h • Hybrid

About The Position

This is a leadership-focused engineering role dedicated to building and delivering high-impact discrete-event simulations using Simio. The primary mission is to drive process understanding, improvement, and adoption through rigorous simulation study, robust change management, and cross-functional collaboration. Knowledge of pharmaceutical manufacturing processes is preferred. The Manager will work in a matrix environment, both within Johnson & Johnson and with our CAR-T collaboration partner, Legend Biotech. The role is located in Raritan, NJ, and is an onsite/hybrid position. The team is focused on positively impacting patients' lives by ensuring high quality in cell therapy products.

Requirements

• Minimum 5 years of hands-on experience in discrete-event simulation, preferably with Simio; a track record of delivering impact through simulation in complex environments.
• Strong capability in modeling, data analysis, and storytelling with data; able to translate complex models into clear, actionable business recommendations.
• Proficiency with programming/scripting to support models and data processing (e.g., Python, R, or equivalent) and familiarity with data visualization tools.
• Excellent communication, presentation, and leadership skills; proven ability to lead multi-functional teams and drive organizational change.
• Bachelor's degree in Engineering, Operations Research, Industrial Engineering, Chemical Engineering, Computer Science, Statistics, or a related discipline.

Nice To Haves

• Master’s degree preferred.
• Experience with pharmaceutical manufacturing processes and GMP/quality systems is highly desirable.
• Exposure to optimization concepts (e.g., LP, MILP, MINLP) and their integration with simulation; while optimization is a secondary focus, familiarity is advantageous.
• Experience implementing simulation-driven solutions across manufacturing floors or large-scale operations.
• Knowledge of process improvement methodologies (e.g., Lean, Six Sigma) and their application via simulation.
• Strategic thinker with the ability to connect simulation outcomes to business goals and financial impact.
• Change-agent mindset: comfortable driving adoption, training, and stakeholder alignment.

Responsibilities

• Lead the design, development, and delivery of end-to-end discrete-event simulation models in Simio to analyze and optimize complex manufacturing and operations processes.
• Drive process improvement programs using simulation to identify bottlenecks, quantify benefits, and define implementation roadmaps.
• Guide change management activities to ensure successful adoption of simulation insights, including stakeholder engagement, training, and communication plans.
• Architect, build, validate, and maintain discrete-event models in Simio to represent current and future-state production and logistics processes.
• Lead process improvement projects from scoping through execution, capturing clear value propositions (capacity, throughput, cycle times, quality, cost) and driving realization plans.
• Develop and maintain modeling standards, templates, and documentation to enable repeatable, scalable simulation work across teams.
• Lead change initiatives associated with simulation-driven improvements, including stakeholder communication plans, training material, and adoption tracking.
• Facilitate decision-making forums by delivering clear, data-driven narratives and visuals; produce executive-friendly reports and dashboards.
