Senior Process Development Engineer Jobs in Chino, CA

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 Manufacturing Development Engineer at Freeform, you will design the processes, tooling, and fixturing behind some of the most geometrically complex metal parts in production today. Tight tolerances, intricate internal features, and multi-step post-processing paths are the norm, not the exception, and these parts are headed for some of the world's most advanced hardware systems. You'll be building processes that don't exist yet, where precision and scale have to work together from day one.

This is a greenfield engineering problem, not an optimization exercise. You'll think in systems, bring a craftsman's eye to your work, and make pragmatic tradeoffs that compound in the right direction over time. If you've thrived in high-velocity hardware environments where the processes didn't exist yet and the stakes were real, this role was built for you.

Responsibilities:  

• Work closely with senior engineers to design and implement scalable manufacturing processes for new hardware and printed parts
• Design, build, and iterate on tooling, jigs, and fixtures to support reliable, high-throughput production
• Develop and refine test procedures and post-processing steps to improve part flow through the factory
• Develop lightweight documentation and process standards to support scaling production without slowing engineering iteration
• Help identify bottlenecks and inefficiencies in how parts, materials, and data move through the factory, and work with cross-functional teams to improve them
• Support the transition of new processes and tooling from R&D into production, partnering with the production team to ensure a smooth handoff

Basic Qualifications:  

• Bachelor's degree in mechanical, manufacturing, or related engineering field
• Internship or professional experience in manufacturing, development engineering, or build engineering
• Experience working with hand tools, machinery, or complex hardware assembly

Nice to Have:  

• 2+ years of experience in a hands-on manufacturing or production engineering role
• Experience with manufacturing process development in a fast-paced hardware environment
• Understanding of GD&T and/or how to read drawings
• Experience with metal additive manufacturing or precision post-processing
• Exposure to fixturing, DFM, or process validation
• Familiarity with MRP/ERP tools and production tracking systems
• Ability to translate high-level engineering goals into practical factory processes

Location: 

• 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.
