Job summary

Raven Space Systems, Inc. seeks a Senior Materials Scientist in Colorado to lead development, testing, and optimization of thermoset and ceramic composites for MAD 3D printing platforms.

This hands-on role couples formulation with production-scale considerations and collaborates with hardware and software teams. You will refine mixing protocols, guide extrusion and microwave-curing, support scale-up, and help advance our material stack for aerospace applications.

Qualifications

• Bachelor’s or Master’s in Materials Science, Chemical Engineering, Polymer Science or a related field.
• 4+ years of experience with composite materials, especially thermosets or ceramics
• Hands-on experience with materials mixing, degassing, and rheological control
• Familiarity with techniques such as DSC, TGA, DMA, tensile testing, and microscopy
• Experienced in developing or scaling manufacturing processes for engineered materials
• Comfort working in cross-disciplinary teams with mechanical, software, and operations personnel

Responsibilities

• Develop and optimize thermoset and ceramic composite formulations for MAD 3D printing platforms.
• Design and refine materials mixing protocols and equipment strategies for batch consistency and printability.
• Lead testing and characterization of material properties, including rheology, cure kinetics, and ablation performance.
• Support scale-up of formulations from lab-scale to production-level batches with tight process controls.
• Interface with software and hardware engineers to ensure proper extrusion behavior, curing dynamics, and print reliability.
• Assist in establishing quality control systems for materials and final part validation.
• Maintain documentation of formulations and results to support repeatability and audit readiness.
• Evaluate and qualify raw material vendors and identify new inputs as needed.
• Contribute to intellectual property and technical strategy for Raven’s composite materials stack
