Senior Computational Scientist / Software Engineer - Feature Scale Process Simulation

Date: Sep 22, 2026

Location: Waltham, MA, US

Worker Category: On-site Flex

About the Role

We are seeking an experienced Computational Software Engineer to help develop the next generation of physics-based semiconductor process simulation technologies. This position is based in Lam Research's Greater Boston area engineering office, where you will work alongside software developers, computational scientists, and semiconductor process experts developing advanced modeling solutions for next-generation semiconductor manufacturing.

This role focuses on the development of advanced feature-scale simulation software that predicts the evolution of nanoscale semiconductor structures during plasma etch, deposition, and other manufacturing processes.

You will work at the intersection of software engineering, computational physics, and semiconductor process technology. The successful candidate will contribute both to the scientific modeling of plasma-surface interactions and to the design and implementation of high-performance simulation software used by researchers, process engineers, and product development teams.

This position requires a unique combination of strong software development skills and a deep understanding of the physical processes that drive feature evolution during semiconductor manufacturing.

Responsibilities

• Design, implement, and maintain computational software for feature-scale semiconductor process simulation.
