Position Overview:

Inversion's reentry vehicles depend on thermal protection materials that perform like the state of the art but cost far less. As the Principal Materials Scientist, you will lead the development of a family of high-performance, low-cost ablative TPS materials — owning them from formulation through automated production at scale. In this role, you will: 

• Develop new ablative TPS material formulations optimized for performance and cost 
• Characterize material response across harsh thermal environments 
• Prototype material fabrication at small scale and mature it toward flight quality 
• Automate fabrication at large scale, drawing on composite manufacturing methods such as automated tape winding, mandrel tooling design, and elevated-temperature curing 
• Plan and execute material characterization campaigns spanning thermal response testing and mechanical property testing across a wide temperature range 
• Work with outside vendors, test facilities, and suppliers to bring new materials, capabilities, and processes in-house at Inversion 
• Mentor senior and early-career engineers across the organization   

Required Qualifications: 

• Bachelor's degree in Materials Science, Materials Engineering, Chemical Engineering, Mechanical Engineering, Aerospace Engineering, or equivalent experience in a relevant field 
• Typically, 12+ years of professional experience developing, formulating, or producing materials for extreme temperature environments 
• Experience with at least one of: carbon phenolic ablators, reinforced carbon/carbon, or refractory ceramic matrix composites 
• Experience with material characterization testing, including both thermal response testing and material strength testing across a wide temperature range 
• Experience prototyping and scaling material fabrication processes 
• Proven ability to work effectively in a fast-paced environment, including prototyping and rapid iteration of new products 
• Must have the ability to obtain and maintain a U.S. government Secret/Top Secret security clearance. 

Desired Qualifications: 

• PhD in Materials Science or a related field 
• Hands-on background with woven, felted, or needled high-temperature fiber preforms and material architectures 
• Experience organizing and executing arc jet material response test campaigns 
• Experience with large-scale composite manufacturing automation (automated tape laying/winding, filament winding, mandrel tooling, autoclave or oven cure development) 
• Experience with ablation and thermal response modeling tools (e.g., FIAT, CHAR, PATO) 
• Experience with thermophysical and thermochemical property measurement (TGA/DSC, laser flash, dilatometry) 
• Experience taking a new material from laboratory formulation through qualification for flight 
• Familiarity with non-destructive evaluation methods for composite and ablative structures 
• Prior experience working in startups and/or small independent teams
