Modeling and Simulation Engineer

Reports to: Director, Simulation Core Technology Center (SCTC)

Location: San Jose, California

Eugenus, a global leader in advanced Atomic Layer Deposition (ALD) and Chemical Vapor Deposition (CVD) technology, takes great pride in its people. Our innovations enable the next generation of semiconductor devices used in AI, advanced memory, and high-performance computing. We are seeking a talented Modeling and Simulation Engineer to join our Simulation Core Technology Center (SCTC) in San Jose, California.

In this role, you will develop and apply advanced physics-based and multiphysics models to understand and optimize semiconductor process equipment and deposition environments. You will work at the intersection of hardware design, process development, and advanced modeling
, helping to drive improvements in process uniformity, chamber performance, gas flow dynamics, thermal behavior, and overall tool architecture.

You will collaborate closely with mechanical engineering, process engineering, systems engineering, and product development teams to translate simulation insights into practical improvements in tool performance, scalability, and manufacturability.

As a Modeling and Simulation Engineer in the Simulation Core Technology Center, you will play a critical role in shaping the design and performance of Eugenus’ next-generation deposition systems. Your work will directly influence reactor architecture, gas delivery design, thermal management, and process uniformity for advanced ALD and CVD platforms.

By applying advanced multiphysics modeling and simulation, you will help accelerate product development, reduce design iteration cycles, and enable breakthrough improvements in semiconductor manufacturing performance. The insights generated from your models will guide key engineering decisions and contribute to the development of innovative solutions used in leading‑edge semiconductor fabs worldwide.

This role offers the opportunity to work on complex, real‑world engineering challenges at the intersection of physics, hardware design, and semiconductor process technology
, while collaborating with a highly skilled multidisciplinary engineering team.
