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.\nWe 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.\nIf 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.\nAbout the Role\nThis 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.\nAs 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.\nWorking 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.\nGrowth Opportunities\nAs Hybron grows, structural analysis is expected to be a key capability that our company develops. As the first stress engineer on the team, there will be significant opportunity to build and lead Hybron’s composites structural analysis team, with pathways to a manager role, director role, and beyond.\nMake key decisions and spearhead initiatives that will directly shape Hybron’s simulation capabilities and methodology\nIdentify and execute on developing/integrating strategic technological capabilities\nManage a team of structural engineers for product and technology development\nContribute to IP and novel analysis techniques\nAssist with technical business development efforts \nSpearhead, oversee, and deliver on large technology development initiatives\nWhat we’re looking for\nMust be a U.S. Person pursuant to EAR and ITAR definitions\nAbility to work in-person at our facility in El Segundo\nBachelor’s degree in a relevant engineering or science field (Composites, Mechanical Engineering, Aerospace Engineering, Manufacturing, Materials Science, Polymer Science, etc.)\n3+ years of industry experience in composites stress analysis\nDemonstrated experience in building and refining an FEA model for a novel material or composition\nAbility to build up an entire FEA system, including software selection and setup, parameter selection, and initial testing and validation\nAbility to utilize FEA to design and optimize composite geometries to minimize weight and optimize performance\nAbility to design mechanical test methods for coupon, representative part, and final part geometries\nAbility to oversee the execution of these tests, ideally with experience in performing the tests themselves\nExperience with failure analysis and root cause analysis\nStrong CAD proficiency for part, assembly, and drawing creation with GD&T\nStrong problem-solving skills, with a drive to deliver on ambitious schedules, even and especially if unconventional & creative solutions are necessary to do so\nThrives in cross-functional organizations with strong communication and collaboration\nNice to Haves\nExperience with simulating both chopped fiber materials and continuous fiber layups\nExperience with Abaqus simulation software\nExperience with thermal simulations\nComposites manufacturing experience\nExperience in the Aerospace or Defense industry\nExperience simulating projectiles under high g-loads\nExperience with creating and presenting business cases to upper management\nExperience working at or leading a small company/business, or with small teams\nCompensation and Schedule\n$138,000 - $249,000 per year \nSignificant stock options in the company\nPotential additional compensation\nMondays - Fridays in-person\n BenefitsPaid time off\nVacation - 10+ working days per year\nSick - 5 working days per year\nHybron observes US holidays with several additional days off to keep you charged\nDaily lunches provided by the company\n401K with employer-matched contributions up to 4% of salary\nHealthcare benefitsMedical insurance -
