Note: The job is a remote job and is open to candidates in USA. Hydrogen Group is seeking a Senior Simulation Engineer to support early-stage manufacturing engineering and factory planning for a new vehicle production program. This role involves developing and analyzing discrete event simulation models to optimize manufacturing system design and capacity planning before equipment procurement and detailed factory design.

Responsibilities

• Develop discrete event simulation models (FlexSim preferred) for manufacturing and material flow applications, including inter-shop buffers, automated storage and retrieval systems (ASRS), autonomous guided vehicle (AGV) traffic, and production line throughput
• Translate high-level manufacturing requirements-including production demand, shift schedules, product mix, first-pass yield (FPY), mean time between failures (MTBF), and mean time to repair (MTTR)-into simulation-ready assumptions and scenarios
• Perform scenario analysis and sensitivity studies to: Validate production throughput against target jobs per hour (JPH) Quantify overspeed requirements, overall performance metrics (OEE/TEE), and buffer capacities Evaluate jobs-per-shift (JPS) consistency and production risk scenarios
• Present simulation findings through concise reports and executive-ready presentations, clearly communicating trade-offs related to throughput, manufacturing risk, equipment utilization, and facility space
• Collaborate with manufacturing engineering, industrial engineering, facility layout, and material flow teams to ensure simulation models accurately reflect production requirements and operational constraints
• Maintain simulation models in accordance with established modeling standards, documentation practices, and handoff procedures

Skills

• Bachelor's degree in Engineering or a related technical discipline, or equivalent practical experience
• 3+ years of experience supporting automotive or advanced manufacturing environments with direct responsibility for discrete event simulation projects
• Advanced proficiency with Autodesk FlexSim
• Demonstrated experience modeling: Multi-line manufacturing systems with buffers, rework, and production variability; Stochastic processes including equipment failures, repairs, and cycle time variability; Throughput analysis, capacity planning, and bottleneck identification
• Strong understanding of manufacturing performance metrics including JPH, JPS, OEE/TEE, MTBF, MTTR, work-in-process (WIP), and buffer sizing
• Experience organizing, validating, and preparing manufacturing data for simulation analysis
• Excellent communication skills with the ability to translate complex simulation results into clear, actionable recommendations for technical and non-technical stakeholders
• Experience developing custom simulation logic using FlexScript, C++, or Python
• Experience supporting greenfield manufacturing facilities, new production launches, or major factory capacity expansion projects
• Familiarity with cross-functional manufacturing engineering disciplines including body, paint, general assembly, battery, drive unit, or material flow systems
