Materials Developer Jobs in Colorado (NOW HIRING)

RavenSpace Systems (Raven) is a venture-backed startup with active governmentprograms and strong commercial momentum, helping revitalize the industrial baseby developing breakthroughs in automated manufacturing to build factories ofthe future and enable the US to compete globally. To meet this critical need, Ravenis building breakthrough composite 3D printing smart factories for thermalprotection, lightweight structures, and more for aerospace and defense. OurMicrowave Assisted Deposition (MAD) innovation unlocks scalable 3D printing ofhighly tailorable, commercial-off-the-shelf thermoset and ceramic compositematerials for the first time. The technology is based on Direct Ink Write (DIW),the most versatile additive manufacturing technology, which utilizes thehighest-performance materials. However, DIW has been stuck in the lab forover 20 years due to its inability to 3D print full-scale composite parts. Raven’s MAD 3Dprinting factories bring DIW to full-scale production of parts and systems. Ourtechnology stack leverages MAD 3D printing, real-time monitoring and controls,and data-driven learning to deploy the most efficient and versatile advancedmanufacturing factories. Our mission is to transform composite manufacturing toalleviate critical supply chain bottlenecks and accelerate innovation.

Position Overview

ASenior Materials Scientist at Raven will lead the development, testing, andoptimization of thermoset and ceramic composite materials used in our MAD 3Dprinting systems. This is a hands-on, foundational role for an experiencedmaterials expert passionate about translating innovative formulations intoreal-world production processes. You will work closely with our hardware andsoftware teams to tune material behavior for extrusion, microwave-curing,ablation resistance, and mechanical performance. You will also help refinemixing protocols and support the scale-up of printable pastes for productionacross thermal protection systems, lightweight structures, and other criticalaerospace applications.
