Build Engineer

Freeform is deploying software-defined, autonomous metal 3D printing factories around the world, bringing the scalability of software to physical production. Our proprietary technology stack leverages advanced sensing, real-time controls, and data-driven learning to produce digitally-verified, flawless parts at unprecedented speed and cost. Our mission is to make the transformative power of 3D printing available to all industries at scale and unlock the future of innovation. 

As a Build Engineer at Freeform, you will take ownership of building, assembling, and integrating complex, custom mechanical systems from scratch for our next gen printing factory. You’ll work hands-on to bring high-performance hardware to life, supporting the transition from prototype to production. This role sits at the intersection of design, manufacturing, and system integration—where you’ll work closely with mechanical, electrical, and software engineering teams to develop and refine new technologies. You will be at the tip of the spear of bringing the world’s first high-volume metal 3D printing factory online and into full-scale production. 

3D printing experience is not required to be successful here—we look for smart, motivated engineers who love solving hard problems, working hands-on, and creating incredible technology! 

Responsibilities:

• Own the assembly, integration, and bring-up of complex mechanical and electromechanical systems for an integrated, automated metal 3D printing factory. 
• Work closely with design and manufacturing engineers to optimize mechanical system builds for performance, precision, and repeatability. 
• Support design efforts by providing real-world build feedback and making modifications to CAD models as needed. 
• Create and iterate on mechanical designs, including custom tooling, test fixtures, and build jigs. 
• Lead alignment, calibration, and precision tuning of mechanical systems to achieve demanding operational requirements. 
• Identify and troubleshoot issues in mechanical and electromechanical subsystems, working with cross-disciplinary teams to resolve problems rapidly. 
• Assist in transitioning builds from R&D into high-reliability production systems. 
• Develop and document scalable manufacturing and assembly procedures. 
• Conduct hands-on testing and validation of mechanical performance, including integration with high-power lasers, high-speed imaging systems, and proprietary motion control hardware. 
• Contribute to continuous improvement efforts by identifying opportunities for increased efficiency, reliability, and scalability in build processes. 

Basic Qualifications:

• Bachelor’s degree in mechanical engineering, aerospace engineering, or manufacturing engineering.
• 2+ years of professional, post-graduation experience in hands-on mechanical system assembly, manufacturing, or prototype development.
• Strong mechanical engineering fundamentals with an ability to troubleshoot and solve mechanical challenges in real time. 

Nice to Have:

• CAD experience (e.g., SolidWorks, NX, or CATIA) including GD&T and drawing documentation. 
• Experience building engines, rockets, drones, robots, machines, satellites, or similar complex mechanical systems for the first time at the prototype stage. 
• Knowledge of metallic manufacturing techniques, including machining, welding, bonding, and fastening. 
• Experience transitioning designs from R&D to production. 
• Familiarity with automation, robotics, or industrial manufacturing systems. 
• Hands-on experience with tooling design, fixture development, or custom fabrication. 
• Experience with design for manufacturability (DFM) and design for assembly (DFA). 
• Experience with metal 3D printing. 

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.
