Process Engineer (New Grad December 2026)

Freeform builds AI-native manufacturing systems that unify software, hardware, and physics to produce industrial-scale parts at the speed of human ideation. By treating manufacturing as a single integrated system, we unlock a new era of innovation where complex hardware is designed, built, and scaled without limits.

As a Process Engineer at Freeform, you will have the unique opportunity to help invent novel processes for the world's most advanced metal 3D printing systems. You will work alongside senior engineers to deep dive into complex, multi physics phenomena, gaining a fundamental understanding of the system and using those learnings to support the creation of new state of the art processes. You will collaborate with an interdisciplinary team of mechanical, software, and simulations engineers to analyze massive in situ data sets as well as post print material characteristics, helping rapidly iterate on improving the printing technology with machine learning.

3D printing experience is not required to be successful here, rather we look for smart, motivated, collaborative engineers who love solving hard problems and creating amazing technology!

• →Support the Process Engineering team in developing a deep understanding of the metal additive process and hardware operation by analyzing massive in situ data sets to gain insight into physical mechanisms of the printing process
• →Assist in the execution of experiments, analyze data, and help develop and optimize processes on a metal additive system
• →Perform post build metrology measurements and analysis of material properties such as tensile strength, surface roughness, and alloy microstructure
• →Generate and track quality metrics of printed customer parts such as dimensional accuracy, defect distribution, and surface roughness

• Based in Hawthorne, our vertically integrated facility brings technology development, R&D, and production together under one roof. We operate at the center of LA’s deep tech ecosystem, surrounded by some of the most ambitious hardware innovation happening anywhere in the country.
• Our fast-paced, cross-functional environment is built on close collaboration, and as such, this role requires full-time onsite presence (five days a week), with very limited exceptions.
