Junior Material Scientist

Location: On-site in Montréal, Quebec, Canada

Company

A venture capital-backed additive manufacturing company developing hardware, software, and materials for high-performance 3D printing.

What you will do

• Operate high-temperature industrial 3D printers and develop expert-level knowledge of their operation.
• Study polymer extrusion behavior, including die swell, viscoelasticity, layer welding, and crystallinity formation.
• Design and run experiments to quantify the phenomena that drive print quality.
• Work with software engineers to convert validated hypotheses into process-control software.
• Develop testing workflows, evaluate software improvements, and scale validated methods across supported materials.
• Help train technicians to expand experimentation across the target material range.

Requirements

• Master’s or PhD in Materials Science, Polymer Science, or Mechanical Engineering.
• Strong understanding of polymer behavior during extrusion processing.
• Theoretical knowledge of polymer rheology, extrusion processing, and thermodynamics.
• Experience with 3D printing, preferably FFF/FDM.
• Experience with high-temperature performance polymers such as Ultem 9085, Ultem 1010, PEEK, or PEKK-A.
• Scientific experience using experimental methods and statistical models based on self-collected datasets.

Culture & Benefits

• Full-time, permanent employment.
• Cross-disciplinary collaboration among polymer scientists, mechanical engineers, and software engineers.
• Opportunity to contribute to tools that make printed parts faster, stronger, and more reliable.
• AI-supported tools may be used during parts of the hiring process, with the option to request human review after an automated rejection.
• Accommodation is available during the application process upon request.
