Senior Development Engineer, Solid Rocket Motors

Join an aerospace and defense propulsion team as a hands-on engineer responsible for solid rocket motor development across multiple interceptor programs. You will help take motor designs from concept through testing and use test results to refine performance and reliability.

• Drive motor architecture grain design and internal ballistics including dual-pulse designs.
• Collaborate with mechanical propellant and manufacturing engineers on motor designs and propellant development.
• Build motors and conduct ground and flight tests.
• Plan instrumentation prepare test documentation analyze results and update performance models and designs.
• Develop concepts for motor sizes suited to new program and customer needs.

• Five to 15 years of solid rocket motor development experience including at least five years of hands-on work.
• Experience owning a motor from grain concept through ground testing; flight test experience is a plus.
• Background in composite-propellant motor design and rapid development and test cycles.
• Fluency with internal-ballistic and thermochemistry codes CAD tools such as NX and ground-test planning and data reduction.
• Understanding of missile systems and experience meeting performance targets with practical materials and propellant approaches.
• Bachelors degree in aerospace mechanical or chemical engineering physics or a related field.
• Experience in a commercial or corporate engineering environment ideally with a team developing solid rocket motors.
• Comfort using AI-assisted coding tools in day-to-day engineering work.

Base salary: $180000 to $220000 annually. Visa sponsorship is not available.
