Materials And Process Engineer

About the Role

This is a full-time, in-person role at our El Segundo facility. As you will be working at an early-stage deep tech startup, this role will span many different responsibilities. You'll need to be a self-starter who's comfortable moving between the lab bench, the manufacturing floor, and cross-functional coordination in the same day. In exchange, you'll have real influence over the product development, strategy, and trajectory of a fast-growing company, and the chance to make rapid professional gains in an environment built for growth.

As a Materials & Process engineer, you’ll connect materials chemistries to the process-structure-property relationship of Hybron’s fiber-reinforced composites, using a novel material construction. You'll guide material selection, formulation changes, and process development to meet the demanding requirements of aerospace, defense, and energy applications — bridging material characterization, manufacturing process, and final part performance across a wide range of material families and processing domains.

Day to day, this looks like running and interpreting material characterization (TGA, DMA, DSC, rheology, mechanical, and similar), designing and executing process and mechanical test campaigns, diagnosing and root-causing part or process failures, and translating findings into process changes that hold up at production scale. You'll work closely with external suppliers and collaborators to source, evaluate, and qualify new material options. You'll also help build the systems such as lab organization, SOPs, and test protocols as we scale.

Working in a high-growth company, you will be wearing many hats: project management, requirements identification, materials characterization, part manufacturing, testing design, test execution, quality inspection, cross-team collaboration, supply chain engagement, and more.

What we’re looking for

• Must be a U.S. Person pursuant to EAR and ITAR definitions
• Ability to work in-person at our facility in El Segundo, Monday-Friday
• Bachelor's degree in a relevant engineering or science field (Composites, Materials Science, Chemistry, Polymer Science, Mechanical Engineering, Aerospace Engineering, Manufacturing, etc.), with a strong chemistry background; advanced degree preferred
• 3+ years of post-graduate industry experience in composite materials design and manufacturing for Mid-level candidates; 5+ years, with demonstrated technical leadership, for Senior-level candidates
• Strong fundamental knowledge of materials science, with demonstrated experience connecting material composition to process-structure-property optimization
• Ability to design and execute material characterization (TGA, TMA, DMA, DSC, rheology) and mechanical coupon testing
• Experience working with external suppliers, customers, and collaborators to identify, procure, and analyze relevant materials
• Experience with failure analysis and root cause analysis
• Experience with lab management, organization, and SOP development
• Comfortable working in a lab and manufacturing environment.
• Strong problem-solving skills, with a drive to deliver on ambitious schedules, including unconventional and creative solutions when needed
• Thrives in cross-functional organizations with strong communication and collaboration
• Must be able to routinely lift, carry, push, and pull objects weighing up to 25 lbs

Nice to Haves
