Job description

Company Overview

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 tasks. You will need to be a self-starter and be adaptable to performing many different jobs. Along with these high expectations comes the opportunity to significantly influence the product development, strategy, and trajectory of a fast-growing startup company. Your work will tangibly impact our company and the composites industry, and you will be able to make rapid professional gains in an environment that encourages growth and innovation.

As the first Stress Engineer, you’ll lay the foundation for and own the structural analysis of Hybron’s fiber‑reinforced composites, using a novel material construction. You’ll build and validate advanced FEA models, guide design and material choices, and ensure parts meet demanding aerospace, defense, and energy requirements. Your work will bridge simulation, testing, and manufacturing, directly shaping how our technology is applied and optimized for mission‑critical applications like artillery shells and aerospace structures.

Working in a high-growth company, you will be wearing many hats: project management, requirements identification, simulation/analysis, product design, testing design, test execution, quality inspection, cross-team collaboration, customer engagement, and more.

Growth Opportunities

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

• Demonstrated experience in building and refining an FEA model for a novel material or composition
• Ability to build up an entire FEA system, including software selection and setup, parameter selection, and initial testing and validation
• Ability to utilize FEA to design and optimize composite geometries to minimize weight and optimize performance
• Ability to design mechanical test methods for coupon, representative part, and final part geometriesAbility to oversee the execution of these tests, ideally with experience in performing the tests themselves
• Experience with failure analysis and root cause analysis
• Strong CAD proficiency for part, assembly, and drawing creation with GD&T
