AON3D Job board

Senior Mechanical Engineer
Montreal, Quebec, Canada


At AON3D, we are working hard to make additive manufacturing with high-performance engineering plastics a more accessible technology for engineers in all industries. As a Senior Mechanical Engineer you will be defining and creating tools for people just like you. We're excited to build devices that not only perform remarkably and create beautiful parts but also reflect careful user experience design. You will be architecting, prototyping, building, and designing the hardware systems of our next generation 3D printers. You will be responsible for key system decisions that affect the final performance and reliability of the products. The ideal person for this role is a problem-solver with a thorough understanding of mechanical and kinematic systems and someone who will take the lead on projects to drive innovation. If you want to lead the design and create the tools you would love to use yourself, we want you as a Senior Mechanical Engineer.


AON3D makes affordable industrial 3D printers designed for printing high performance thermoplastics, including PEEK, PEKK, ULTEM™ 9085, polycarbonate and more. The AON-M2, its flagship 3D printer, is a direct response to demands for hotter print conditions and the careful thermal control needed for producing strong and dimensionally stable parts from advanced materials. Most importantly, it offers an open filament platform that empowers users to choose the right materials for their project and slash costs by avoiding expensive proprietary materials and license fees.

AON3D is dedicated to ensuring designers and engineers have greater access to cutting edge materials and affordable 3D printers so they can drive tomorrow's innovation today.
