Additive Manufacturing Summer Intern Jobs in California

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 Engineering Intern at Freeform, you'll be at the forefront of scaling production for high-performance metal 3D printed parts. You'll work with a talented engineering team from some of the world's most innovative companies across a range of projects to develop and refine the processes, tooling, and CNC machining workflows that enable precision manufacturing at speed and scale. This role is hands-on and fast-paced, ideal for someone eager to learn and contribute to the development of our autonomous metal 3D printing factories. You'll focus on optimizing post-processing and machining operations, helping to bridge the gap between R&D and production.  

3D printing experienceis not required tobe successful here - rather we look for smart, motivated, collaborative individuals who love solving hard problems and creating amazing technology!  

Responsibilities:  

• Support the design and implementation of scalable manufacturing processes for new hardware and printed parts  
• Assist with fixturing, test procedures, and post-processing steps to improve part flow through the factory  
• Help develop documentation and process standards to support production scaling  
• Build and iterate on tooling, jigs, and test setups for reliable, high-throughput production  
• Identify bottlenecks and inefficiencies in part, material, and data flow- and work with cross-functional teams to improve them  
• Support early production efforts and help transition R&D into high-rate manufacturing 
• Contribute to CNC machining workflows, including programming, setup, and optimization of multi-axis operations for post-processing of printed parts 

Basic Qualifications:  

• Currently enrolled in a bachelor's degree in mechanical, aerospace, or manufacturing engineering from an ABET accredited university or college 
• Hands on manufacturing or build experience from internships or engineering clubs such as FSAE, Baja SAE, solar car, rocket club, robotics club, or similar 
• Experience working with hand tools, machinery, or complex hardware assembly 

Nice to Have:  

• Advanced degree (Master's, PhD) in mechanical, aerospace, or manufacturing engineering 
• Experience with CNC machining, including 3 or 5-axis programming and/or setup 
• Experience with metal additive manufacturing or precision post-processing 
• Exposure to fixturing, DFM, or process validation   
• Experience scaling early-stage R&D into production 
• Familiarity with MRP/ERP tools and lightweight production tracking systems 
• Familiarity with manufacturing process development in a fast-paced hardware environment  
• Ability to translate high-level engineering goals into practical factory processes  
• Comfortable working in fast-paced, ambiguous environments and iterating quickly (comfortable building the plane as we fly it) 
• Strong communicator who collaborates across disciplines and proactively seeks support when needed 
• Willing to take ownership of tasks big and small, with a hands-on, problem-solving mindset 
• Strong work ethic with a refuse-to-fail mindset 
• Demonstrated indicators of excellence and/or achieving success against adversity (i.e. top academic performance, leadership in engineering clubs, first-generation college student, or other examples of resilience and achievement) 

Location: 

• We are located in Hawthorne, CA in a 35,000 square foot, state-of-the-art facility featuring large open spaces for team collaboration, R&D, and production, as well as easy access to the 405, 105, and 110 freeways.Our facility is in the heart of Los Angeles' vibrant emerging tech ecosystem alongside many other high growth startups and enterprises. 

What We Offer:  

• We have an inclusive and diverse culture that values collaboration, learning, and making deliberate data-driven decisions 
• We offer a unique opportunity to be an early and integral member of a rapidly growing company that is scaling a world-changing technology 
• Compensation and Benefits 
  • The compensation for this role is $30/hour 
  • Relocation assistance 
  • Free daily catered lunch and dinner, and fully stocked kitchenette 
  • Casual dress, flexible work hours, and regular catered team building events
