Job summary

Hybron in El Segundo is seeking a Materials & Process engineer to bridge chemistry and manufacturing for high-performance composites. You will move between lab bench and production floor, guiding material selection, formulation changes, and process development to scale Hybron’s fiber-reinforced composites.

You’ll run material characterization tests (TGA, DMA, DSC, rheology), design experiments, and work with suppliers to qualify new materials, while building lab SOPs and scalable testing

Qualifications

• Bachelor's degree in engineering or science with strong chemistry background.
• Experience in materials science and process optimization.
• Ability to design and execute material characterization and mechanical testing.

Responsibilities

• Connect material chemistries to process-structure-property relationships in Hybron’s composites.
• Guide material selection, formulation changes, and process development for aerospace/defense needs.
• Run and interpret material characterization tests (TGA, DMA, DSC, rheology) and mechanical coupons.
• Collaborate with suppliers and build lab SOPs and testing protocols for scale.

Job description

About the job

Hybron is an advanced manufacturing company that is building lightweight composites at mass production scale. At Hybron, we have pioneered a new composites manufacturing process that enables complex, high performance composite parts to be produced 10-100 times faster than traditional manufacturing, at a fraction of the cost.

We recently closed an oversubscribed $25M seed round, are backed by the Northrop Grumman Technology Accelerator, and are rapidly growing to commercialize and mass produce composite products at a scale never seen before. Our current focus is applying our proprietary process to composite artillery shells, solid rocket motor nozzles, gas turbine engine components, and airframes.

If you want to join a rapidly growing company working on cutting edge composites technology while building capabilities for the warfighter and reshoring U.S. manufacturing, then we want to speak with you.

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

• Experience and advanced knowledge with composite manufacturing methods
• Experience with chopped and continuous fiber materials and manufacturing
• Experience with Design of Experiments (DOE) or statistical process optimization tools (e.g., JMP, Minitab)
• Experience scaling a process from lab/pilot scale to production volume
• Familiarity with quality systems relevant to aerospace/defense manufacturing (AS9100, NADCAP, MIL-SPEC)
• Experience with adhesives and various resin chemistries, including but not limited to epoxy, BMI, cyanate ester, vinyl ester, phenolics
• Experience scaling a process from lab to pilot+ scale
• Experience in the Aerospace or Defense industry
• Experience working at or leading a small company/business, or with small teams

Growth Opportunities

As Hybron grows, Materials & Process function is expected to be a key technological enabler for our company’s future. There will be significant opportunity for you to build and scale Hybron’s Materials & Process team, with pathways to a manager role and beyond.

• Make key decisions and spearhead initiatives that will directly shape Hybron’s process capabilities and methodology
• Identify and execute on developing/integrating strategic technological capabilities
• Manage a team of engineers for product and technology development
• Contribute to IP and novel manufacturing techniques
• Assist with technical business development efforts
• Spearhead, oversee, and deliver on large technology development initiatives

Compensation and Schedule

• $105,000 – $167,000 per year
• Significant stock options in the company
• Potential additional compensation
