Sr. R&D Mechanical Engineer – Systems (Berkeley, CA)

Location: Berkeley, CA 

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 mechanical designer/engineer with five or more years of experience designing complex manufacturing equipment preferably involving composite materials. You are a problem solver with a knack for 3D thinking, experience building advanced systems, and a desire for simplicity and elegance. You should be experienced in developing, prototyping and improving your designs in close collaboration with a skilled R&D team. 

As Our Sr. R&D Mechanical Engineer, You Will:

  • Design and prototype machines and systems with novel composite process methods 
  • Improve current methods and systems by designing more efficient, more effective machines 
  • Hands-on prototyping, fabrication, and testing of new systems and processes working closely with the process R&D lead
