Senior Additive Manufacturing Engineer

The role

This person will execute and improve metal additive manufacturing workflows for carbon nanomaterial-infused aluminum and copper systems. They will support parameter development, build preparation, print execution, and post-processing.

What you will do

• Support LPBF, DED, and related metal additive manufacturing experiments
• Prepare builds, define build layouts, support orientation and support strategy, and help execute design-for-additive-manufacturing decisions
• Develop and refine print parameters, scan strategies, thermal management approaches, and process recipes
• Support powder and feedstock handling, build setup, machine operation, sample removal, post-processing, and documentation
• Help diagnose print defects including porosity, cracking, distortion, poor bonding, surface quality issues, and inconsistent build outcomes
• Partner with nanomaterials, process, and testing teams to connect print parameters to performance
• Help build and maintain fixture designs, CAD files, build records, process travelers, test plans, and experiment summaries
• Support DOE-style experimentation, repeatability studies, and root-cause investigations
• Work with vendors, machine shops, external labs, and equipment suppliers

Required qualifications

• BS, MS, or PhD in mechanical engineering, materials science, manufacturing engineering, welding engineering, metallurgical engineering, physics, or a related field
• 2+ years of hands-on experience in additive manufacturing, metal processing, powder metallurgy, laser processing, welding, or a closely related field
• Experience with at least one relevant process area such as LPBF, DED, WAAM, powder metallurgy, laser processing, welding, or metal AM post-processing
• Strong hands-on engineering instincts and comfort working in a lab, shop, or manufacturing environment
• Ability to execute experiments, analyze results, troubleshoot problems, and communicate findings clearly
• Strong technical documentation skills, including build notes, test plans, process updates, and experimental summaries
• High ownership, attention to detail, and comfort working in a fast-moving startup environment

Nice to have

• Experience with LPBF or DED metal additive manufacturing (or similar, ie. WAAM, etc.)
• Experience with aluminum, copper, conductors, metal matrix composites, or non-standard material systems
• Familiarity with AM build preparation tools, CAD, slicing, support generation, scan strategy setup, or print simulation
• Experience with powder handling, feedstock preparation, post-processing, sample preparation, or materials characterization
• Familiarity with DOE, statistical analysis, root-cause analysis, or process optimization
• Experience working in a startup, research lab, advanced manufacturing team, or hardware development environment

Benefits

• Competitive cash compensation
• Meaningful equity
• Direct technical ownership over a core manufacturing platform
• The chance to define the playbook for nanomaterial-enhanced metal additive manufacturing
• Relocation support for employees moving from outside the Los Angeles area
