Location:
United Arab Emirates (Remote) Employment Type: Full-Time Work Arrangement: 100% Remote — Work From Home Level: Senior

About the Role
We are seeking an experienced Senior Rolling Stock Dynamics Specialist to provide advanced engineering analysis, technical evaluation, and performance optimization for railway vehicles and rolling stock systems. The successful candidate will focus on vehicle dynamics, ride quality, stability, wheel–rail interaction, suspension performance, and vibration analysis to support railway safety, reliability, passenger comfort, and operational efficiency. This fully remote position emphasizes engineering simulations, computational analysis, technical documentation, design reviews, and performance assessments. The ideal candidate will have strong expertise in railway engineering, mechanical dynamics, and simulation tools, with the ability to collaborate remotely with rolling stock manufacturers, railway operators, infrastructure engineers, and multidisciplinary project teams.

Key Responsibilities

Perform advanced rolling stock dynamics analyses to evaluate vehicle stability, ride quality, curving performance, and operational behavior under different service conditions. Develop and review mathematical models and computer simulations of railway vehicles, including bogies, wheelsets, suspension systems, and vehicle–track interactions. Analyze wheel–rail contact mechanics, wheel and rail profiles, contact forces, and their influence on vehicle performance and safety. Evaluate primary and secondary suspension characteristics to optimize ride comfort, vibration isolation, stability, and vehicle handling. Conduct simulation-based assessments of derailment risk indicators, wheel unloading, lateral forces, and other relevant vehicle dynamics performance measures. Assess vehicle behavior under different track geometries, operating speeds, loading conditions, and environmental scenarios. Review and interpret simulation results, test datasets, and operational measurements to identify performance issues and recommend engineering improvements. Support the assessment of compliance with applicable railway standards, technical specifications, and vehicle acceptance requirements. Evaluate the dynamic performance of locomotives, passenger coaches, metro vehicles, high-speed trains, and freight rolling stock, as relevant to project requirements. Perform sensitivity analyses and engineering investigations to assess the effects of design parameters, suspension settings, vehicle mass distribution, and wheel–rail conditions. Collaborate with mechanical, structural, braking, bogie, track, and vehicle design engineers to resolve technical issues affecting rolling stock performance. Review engineering drawings, technical specifications, vehicle configuration documents, and design change proposals from a dynamics perspective. Support virtual validation, simulation-based verification, and technical reviews for new rolling stock designs and fleet modifications. Analyze vibration, noise, and ride comfort data to identify potential causes of excessive movement, instability, or passenger discomfort. Contribute to root-cause investigations involving abnormal vehicle behavior, wheel and rail wear, suspension performance, and dynamic interaction issues. Prepare detailed technical reports, simulation summaries, engineering recommendations, and risk assessments for project stakeholders. Maintain accurate records of simulation assumptions, model configurations, validation results, and engineering decisions. Monitor developments in railway vehicle dynamics, simulation methodologies, and applicable technical standards. Provide technical guidance to junior engineers and support the development of consistent modelling, analysis, and reporting practices.
Qualifications and Experience
Bachelor's degree in Mechanical Engineering, Railway Engineering, Automotive Engineering, Applied Mechanics, or a related engineering discipline. Significant professional experience in rolling stock engineering, railway vehicle dynamics, mechanical simulation, or a related technical field. Strong understanding of railway vehicle dynamics, including lateral and vertical motion, hunting stability, curving behavior, and ride comfort. Knowledge of wheel–rail contact mechanics, wheel and rail profiles, contact forces, and vehicle–track interaction principles. Experience analyzing bogies, wheelsets, primary and secondary suspension systems, dampers, and related mechanical components. Proficiency with multibody dynamics simulation software, such as SIMPACK, VAMPIRE, or equivalent railway vehicle dynamics tools. Familiarity with finite element analysis (FEA), vibration analysis, signal processing, and engineering data visualization tools. Understanding of railway vehicle performance requirements and relevant standards, such as EN 14363 and applicable parts of the EN 12299 series. Experie
