Ideal candidates will have experience in vehicle dynamics and structural analysis, with a preference for those who have worked in railway or road vehicle applications.

Responsibilities:

• Design and analyze vehicle structures, mechanisms, and actuated systems with a focus on dynamics, kinematics, and structural integrity.
• Develop, optimize, and maintain CAD models for mechanical components and assemblies.
• Conduct multibody dynamics simulations to assess system performance under real-world conditions.
• Perform finite element analysis (FEA) for structural, fatigue, and modal performance.
• Investigate and resolve mechanical failures to improve system reliability.
• Support prototype development, testing, and validation of vehicle components as part of a multi-disciplinary team.

Requirements:

• 5+ years of experience in mechanical engineering with a focus on structures, dynamics, simulation, and machine design.
• Strong proficiency in CAD software (SolidWorks, CATIA, Siemens NX, or similar).
• Experience with multibody dynamics (MBD) simulation tools (Simpack, Adams, or equivalent).
• Expertise in finite element analysis (FEA) and computational simulation.
• Strong understanding of mechanical vibrations, fatigue analysis, and structural mechanics.
• Experience working with mechanical systems in transportation, automotive, or railway applications.
• Ability to interpret and apply engineering standards and safety regulations.

Preferred Qualifications:

• Experience in railway vehicle dynamics, bogie design, or track interaction.
• Knowledge of railway industry standards (EN, UIC, APTA, FRA, or similar).
• Experience with prototyping, manufacturing processes, and design for manufacturability (DFM).
• Proficiency in Python, MATLAB, or similar scripting tools for simulation automation.
