AON3D Job board

Firmware Developer
Montreal, Quebec, Canada


Under the hood AON3D printers are sophisticated robotic platforms which are programmed to produce great results and a seamless user experience. To achieve this we employ a wide range of motion planning, control, and computational algorithms.

We are looking for a Firmware Developer who can fuse high-performance software algorithms and robotic control to build world-class printer control software. We’re working to reinvent additive manufacturing to enable designers, engineers, and researchers all around the world to more easily make their visions a reality. Previous projects have included automatic bed levelling, serial communications optimization, PID control tuning and more. You will have plenty of opportunities to work on all areas of our codebase and make significant changes that will help steer the company growth and make sweeping impacts for our users.


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.
