Composites Stress Engineer

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.

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 need to be a self‑starter and 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.

As Hybron grows, structural analysis is expected to be a key capability the 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.
