Associate AI / Simulation Engineer, Thermal/CFD

In this role, you will apply strong fundamentals in fluid dynamics and heat transfer to develop and execute simulations addressing real-world electronics and component-level thermal challenges. You will contribute to both internal simulation initiatives and customer-facing engineering efforts, including product development support, field issue troubleshooting, and safety and compliance evaluations.

Working closely with senior technical experts, you will progressively take ownership of model development, simulation execution, results interpretation, and technical documentation, while building the capability to deliver clear, data-driven engineering insights.

Job Responsibilities:

• Develop and execute Computational Fluid Dynamic (CFD) and thermal simulations for electronics cooling applications, including airflow, forced and natural convection, and conjugate heat transfer 
• Support component-, board-, enclosure-, and sub-system–level thermal analysis for electronic products 
• Assist in rapid model setup and simulation turnaround to support internal service requests and customer engineering needs 
• Apply appropriate boundary conditions, material properties, and solver settings under guidance from senior engineers 
• Support steady-state and transient thermal analyses, including power ramp-up, duty cycles, and basic fault scenarios 
• Post-process and interpret simulation results to identify thermal risks, airflow issues, and design improvement opportunities 
• Assist in correlating simulation results with experimental data, lab measurements, or field observations 
• Prepare clear technical summaries and documentation of assumptions, methods, results, and limitations 
• Support verification and validation (V&V) activities by following defined modeling and review processes 
• Engage with senior engineers to understand UL safety considerations, certification objectives, and modeling expectations 
• Learn and apply best practices in mesh strategy, numerical stability, convergence assessment, and result credibility 
• Collaborate effectively with cross-functional teams and contribute to a learning-oriented, supportive team culture 

Qualifications:

• Bachelor’s or Master’s degree in Mechanical Engineering, Thermal Sciences, Aerospace Engineering, or a related field from a reputed institution 
• 2–5 years of industrial or applied experience in Computational Fluid Dynamic (CFD) and thermal-fluid simulations (internships and thesis work may be considered) 
• Strong fundamentals in: Fluid mechanics and basic turbulence modeling, Heat transfer (conduction, convection, radiation), Thermodynamics relevant to electronics cooling, 
• Hands-on exposure to CFD model setup, solution execution, and result interpretation 
• Familiarity with at least one commercial simulation tool such as: ANSYS Icepak, ANSYS Fluent, FLOTHERM, FLOEFD, STAR-CCM+, COMSOL, or similar software
• Basic understanding of: Mesh generation and grid quality concepts, Solver settings and convergence behavior, Ability to follow structured modeling workflows and technical guidelines 
• Good written and verbal communication skills, with ability to explain results clearly 
• Self-motivated, detail-oriented, and comfortable learning in a technically rigorous environment 
• Exposure to electronics thermal management, including ICs, PCBs, heat sinks, fans, vents, and enclosures 
• Awareness of electronics packaging constraints (space, airflow resistance, materials, power dissipation) 
• Basic experience with thermal testing, such as thermocouple placement, temperature measurement, or data acquisition 
• Introductory experience correlating simulation results with test or experimental data 
• Familiarity with transient thermal behavior and power cycling effects 
• Interest in automation, scripting, or AI-assisted simulation workflows
