As a Materials Engineer, you will be at the forefront of expanding the materials portfolio of Markforged systems and expanding the possibilities of what our customers can accomplish. You will continuously improve our existing fused filament fabrication (FFF) material set and bring new FFF materials through development into manufacturing and onto the market. To do this, you will use your materials knowledge to investigate structure-process-property relationships, develop processes for manufacturing readiness, and build new methods for testing next generation materials. You will utilize your know-hows to improve material performance and troubleshoot production issues. You will work directly with a team of material scientists, print engineers, manufacturing engineers and hardware engineers to contribute to a collaborative and engaging work environment.
