What is a CFD Internship job?

A CFD (Computational Fluid Dynamics) internship involves using simulation software to analyze fluid flow, heat transfer, and related physical phenomena. Interns typically work with engineering teams to develop models, run simulations, and interpret results for real-world applications in industries like aerospace, automotive, and energy. This role helps students gain hands-on experience with CFD tools such as ANSYS Fluent, OpenFOAM, or STAR-CCM+. It also involves validating simulations with experimental data and optimizing designs based on analysis.

What are the key skills and qualifications needed to thrive in the Cfd Internship position, and why are they important?

A Cfd Internship requires a solid background in fluid mechanics, thermodynamics, and numerical methods, typically supported by coursework in mechanical or aerospace engineering. Competence in using simulation software such as ANSYS Fluent, OpenFOAM, or COMSOL Multiphysics is highly valued. Strong analytical thinking, attention to detail, and effective communication help interns excel in team environments and present results clearly. These skills are crucial for conducting accurate simulations, interpreting data, and contributing meaningful insights to engineering projects.

What kinds of projects or tasks can I expect to work on during a CFD internship?

As a CFD intern, you can expect to assist with setting up and running computational fluid dynamics simulations, analyzing simulation data, and contributing to technical reports or presentations. Interns often support senior engineers on real-world industry projects, such as aerodynamic design, thermal management, or process optimization. You’ll likely use specialized simulation software and work as part of a multidisciplinary team, participating in team meetings and project reviews. This hands-on experience helps you build practical skills and exposes you to various aspects of engineering problem-solving.

Job description

About Etched

Etched is building the world’s first AI inference system purpose-built for transformers - delivering over 10x higher performance and dramatically lower cost and latency than a B200. With Etched ASICs, you can build products that would be impossible with GPUs, like real-time video generation models and extremely deep & parallel chain-of-thought reasoning agents. Backed by hundreds of millions from top-tier investors and staffed by leading engineers, Etched is redefining the infrastructure layer for the fastest growing industry in history.

Job Summary

We are seeking a talented Thermo-Mechanical, CFD Simulation Engineering Intern focused on Chip-on-Wafer-on-Substrate (CoWoS) package development to join our Advanced IC Packaging Team in Fall '26, Spring '27, or Summer '27. You'll use tools like ANSYS Mechanical APDL and ANSYS FLUENT to perform critical thermo-mechanical/CFD analysis and contribute to next-generation high-performance computing systems.

Key responsibilities

  • Develop FEA models for CoWoS-based IC packages using ANSYS Mechanical APDL

  • Perform thermo-mechanical stress/strain analysis and thermal cycling simulations

  • Analyze package warpage, solder joint reliability, and interconnect stress

  • Develop CFD models using ANSYS FLUENT for solder reflow modeling

  • Collaborate with design engineering teams on package development

You may be a good fit if you have

  • Education & Experience

    • Pursuing a degree in Mechanical Engineering or related field

    • Academic or project experience with FEA/CFD tools and analysis

  • Technical Skills

    • Proficiency in SOLIDWORKS/NX, ANSYS Mechanical APDL and ANSYS FLUENT

    • Understanding of semiconductor packaging materials and processes

    • Strong grasp on non-linear properties of materials (elastic-plastic, viscoelastic)

    • Familiarity with CoWoS-S/L/R, TSVs, or 2.5D/3D integration concepts

    • Basic programming/scripting skills (APDL, Python, MATLAB)

Strong candidates may have some experience with

  • Knowledge of solder joint reliability and failure analysis

  • Familiarity with JEDEC standards and reliability testing

  • Previous internship in semiconductor industry

We encourage you to apply even if you do not believe you meet every qualification.

Program details

  • 12-week paid internship

  • Generous housing support for those relocating

  • Daily lunch and dinner in our office

  • Based at our office in San Jose, CA

  • Direct mentorship from industry leaders and world-class engineers

  • Opportunity to work on one of the most important problems of our time

How we’re different

Etched believes in the Bitter Lesson. We think most of the progress in the AI field has come from using more FLOPs to train and run models, and the best way to get more FLOPs is to build model-specific hardware. Larger and larger training runs encourage companies to consolidate around fewer model architectures, which creates a market for single-model ASICs.

We are a fully in-person team in West San Jose, and greatly value engineering skills. We do not have boundaries between engineering and research, and we expect all of our technical staff to contribute to both as needed.
