Engineer Sr.

Sr. simulation Engineer

Key Responsibilities

• Utilize simulation tools (Ansys) and analytical skills to evaluate fluid flow systems and recommend design improvements across various stages of the product development lifecycle.
• Support global engineering teams across the US, EMEA, and APAC with advanced CFD analysis related to filtration systems and exhaust SCR systems.
• Lead efforts to enhance virtual validation and reduce physical testing by developing computational best practices, increasing simulation fidelity, and validating simulations against experimental data (flow benches and analytical tools).
• Build and validate CFD models from CAD (NX/Pro-E) and/or create parametric models to conduct design sensitivity and trade-off analyses.
• Apply optimization methods and surrogate modeling techniques to explore design space and recommend performance-optimal solutions.
• Contribute technical expertise to global product development initiatives and provide actionable design guidance.

Qualifications

• M.E./M.Tech in Mechanical Engineering/ Automotive Engineering/ Chemical Engineering or a related discipline
• Minimum 5 years of hand-on experience with Ansys Fluent for complex fluid systems.

Technical Skills

• Solid foundation in fluid mechanics and computational methods related to fluid flow and heat transfer.
• Hands-on experience in steady and unsteady fluid flow analysis, thermal simulations including conjugate heat transfer, and multiphase modeling (spray, particle tracking, wall film, and Volume of Fluid (VOF) methods).
• Practical experience using Ansys software, particularly in engine exhaust after-treatment systems such as SCR mixing. Exposure to setup, simulation, and interpretation of complex flow phenomena.
• Working knowledge of multi-objective optimization techniques and surrogate modeling approaches for design exploration and performance improvement.
• Proficiency in scripting (e.g., Python, APDL, etc.) to automate simulation workflows.
• Knowledge of distributed computing, job schedulers, and performance tuning for running large-scale simulations efficiently.
• Awareness of

  digital thread concepts

  and simulation data integration in product lifecycle management (PLM) systems.
• Experience working with CAD tools such as Uni-Graphics (NX) and/or PTC Creo (Pro/E) for design modeling and geometry preparation.
• Strong ability to read, interpret, and analyze engineering drawings, specifications, and technical documentation.

Soft Skills

• Self-motivated, proactive problem-solver with a strong sense of ownership.
• Excellent collaboration skills across time zones and cultures.
• Effective communicator and adept at resolving technical queries.
• Willingness and ability to work flexible hours and across multiple time zones as required to meet project demands
