Composite Process Engineer

About Us

From a team that has been instrumental in the development of leading 3D printing and advanced manufacturing technologies comes the biggest development yet. At higher strength and lower density than titanium, carbon fiber composites hold the potential to change the world by unlocking novel design architectures that deliver unparalleled performance at lighter weights. Despite this potential, the complexity and cost of designing and manufacturing these anisotropic materials has limited their use to high-end, niche applications. Arris Composites has solved this problem and some of the top companies in the world have taken notice. New design latitude and improved performance provides competitive advantages for leaders across the industrial and consumer markets. Your view of composites is about to change.


Arris Composites is seeking an experienced composite process engineer with five or more years of experience using composite materials to produce parts.  You are a problem solver with a knack for 3D thinking, experience building working mechanical devices, a deep intuitive sense of Newtonian physics, and a desire for elegance. You should be experienced in developing, prototyping and improving your designs in close collaboration with a skilled team.


  • Optimize process of using composite materials to create end-use parts
  • Select the proper starting materials to achieve the target specifications (e.g. mechanical, thermal, dimensional, surface finish, etc.)
  • Determine the processing conditions needed to achieve target specifications (e.g. mechanical, thermal, dimensional, surface finish, etc.)
  • Hands-on prototyping, fabrication, testing of new composite materials
  • Work collaboratively with technical and non-technical team members to achieve shared goals.
  • Estimate technical risk and time to complete tasks
  • Work with a multidisciplinary team in a dynamic work environment


  • Minimum MS in mechanical engineering, industrial engineering, operations research, or materials science
  • 5+ years experience working with thermoplastic composite materials
  • Experience in bonding, welding, melting, and processing of thermoplastic composite materials
  • Experience in correlating out-of-specification parts to process, material, and/or design issues
  • Experience in controlling thermal contraction and expansion of thermoplastic composites during processing
  • Experience with impregnating and wetting out fibers with thermoplastic resin
  • Knowledge of composite laminate theory and optimal fiber alignments
  • Excellent attention to detail
  • Good written and verbal communication skills.  You can sketch well enough to communicate complex ideas.
  • You have vision and can respectfully disagree when you see things differently than others. But you also can recognize when your concept isn’t the one that we’re moving forward with, and you can get 100 percent behind the new direction.
  • Great references


  • Benefits include health, vision, dental, and life insurance, and snacks including but not limited to peanut butter pretzels.


  • This position is in Berkeley, CA. It’s within walking distance to Amtrak, ~1.5 miles from BART, and ~ 1 mile from the Marina Ferry (direct from SF Ferry Building)
