Mechanical Engineer Intern I - India

Role Overview

As a Thermal-Mechanical Engineering Intern, you will support the R&D team in developing physics-based engineering models and thermal-management solutions for electronics and high-performance systems. The role involves translating heat-transfer, fluid-flow, and material-behavior problems into practical analytical methods and Python-based engineering tools.

Responsibilities

• Develop physics-based mathematical models for thermal and fluid systems.
• Create Python programs for engineering calculations, parametric studies, sensitivity analysis, and result visualization.
• Model fluid distribution, pressure losses, flow resistance, and heat-transfer coefficients.
• Develop thermal resistance models for heat sinks, cold plates, TIMs, and multilayer assemblies.
• Evaluate deformation, thermal strain, and stress in assemblies.
• Support the development of reduced-order models and digital twins.
• Validate analytical and Python models against CFD, FEA, or experimental data.
• Assist with technical documentation and design summaries.
• Support CAD and simulation activities where required.

Requirements

• Pursuing or recently completed an M.Tech, M.E., or equivalent degree in Mechanical Engineering, Thermal Engineering, or a related field.
• Strong understanding of conduction, convection, radiation, and thermal-resistance concepts.
• Good understanding of fluid mechanics and solid mechanics.
• Ability to derive engineering equations from first principles.
• Hands-on Python programming experience for numerical calculations and data processing.
• Familiarity with NumPy, SciPy, pandas, and Matplotlib.
• Good technical communication and documentation skills.

Nice to Have

• Experience with Ansys Mechanical, Icepak, Fluent, or CFX.
• Familiarity with transient thermal analysis and thermal-stress analysis.
• Experience with Git and version control.
• Basic CAD experience.
