Job Description

Job Summary

We are seeking a talented Simulation Engineer to join our team, specializing in Digital Twin Simulation and Network Optimization. This role involves designing and implementing simulation models and optimization solutions to enhance warehouse logistics, resource allocation, and network efficiency. The ideal candidate will bring strong technical expertise in Python, simulation modeling, and optimization techniques, along with a passion for solving complex operational challenges.

Responsibilities

Develop and maintain digital twin simulations for warehouse and logistics systems, modeling system states, events, and resource interactions. Create and optimize network models to improve flow, resource allocation, and operational performance. Collaborate with stakeholders to integrate simulation and optimization solutions into existing workflows. Analyze simulation outputs to pinpoint inefficiencies and recommend actionable improvements. Write modular, testable, and efficient code to support simulation and optimization projects. Document processes, methodologies, and findings for technical and non-technical audiences.
