## Job description

## About Us

AON3D is a venture capital-backed, Montréal-based additive manufacturing hardware, software, and materials company. Our solutions drive innovation for hundreds of businesses in 25+ countries worldwide, ranging from small businesses to multinational Fortune 500 corporations.

Our mission is to create intelligent tools that automate and optimize the additive manufacturing process, enabling anyone to manufacture high performance parts, in any material, with the touch of a button.

## About The Role

Printing high temperature high performance polymers isn't magic, it's science turned into complex machinery and process control. In the R&D team we focus on understanding polymer behavior, quantifying it and then turning it into process control to guarantee strong and reliably printed parts for our customers

## What You Will Do

- Operate AON's high temperature industrial 3D printers to the point of becoming an expert
- Understand and formalize key polymer extrusion behaviors like die swell, the effects of viscoelasticity on print quality, layer welding, crystallinity formation and many more.
- Propose ways of quantifying driving phenomena experimentally, then running the experiments and finally working with the software side of our team to turn validated hypothesis into concrete software.
- Devise test workflows, run tests, give feedback on what parts of our software platform needs to be improved
- Once you prove your hypothesis for one materials, you will scale it to all materials we support.
- You will help train technicians to scale experimentation across the material range we care about.

## What We Are Looking For

- Masters or PhD in Material Science, Polymers Science or Mechanical Engineering
- Strong intuition on polymer behavior during processing through extrusion
- Theoretical knowledge of polymer rheology, extrusion processing, and thermodynamics
- Experience in 3D printing, preferably in FFF/FDM
- Experience working with high temperature performance polymers (Ultem 9085, Ultem 1010, PEEK, PEKK-A, etc)
- Scientific mindset and background – proven examples of using the scientific method to study a phenomenon
- Experience building statistical models to predict physical or chemical phenomena, based on self-collected datasets
- Initiative, driven and independence – you take ownership of your projects and have the experience to prove it
- Open to learning cross-disciplinary skills. Our team is composed of polymer scientists, mechanical engineers and software engineers. We like working together to build useful tools that make our prints faster, stronger and more reliable.
