The Solid Rocket Propulsion Engineer is responsible for the design, analysis, development, testing, and production support of solid rocket propulsion systems and related hardware across the product lifecycle.

The position reports to the Engineering Manager and is part of the Engineering Department. This role is onsite based in Reno, Folsom, Long Beach, Huntsville or Remote. Relocation assistance may be provided to qualified candidates.

In this role, the essential functions are:

- Design, analyze, and develop solid rocket motor and propulsion system components, subsystems, and integrated hardware from concept through qualification and production.

- Perform engineering analyses related to motor performance, internal ballistics, combustion, thermal environments, structural integrity, insulation, nozzles, grains, cases, and other propulsion hardware as applicable.

- Develop and execute engineering requirements, analyses, drawings, specifications, test plans, procedures, and technical reports.

- Support propulsion development and qualification testing, including test planning, instrumentation requirements, data review, anomaly investigation, and root-cause/corrective-action activities.

- Work cross-functionally with manufacturing, quality, test, systems, program management, and suppliers to mature designs and resolve technical issues.

- Support design reviews, risk assessments, failure investigations, and configuration changes throughout the product lifecycle.

- Apply engineering judgment and technical rigor to balance performance, manufacturability, reliability, cost, schedule, and safety requirements.

- Depending on experience level, independently lead technical work packages or provide technical leadership and mentorship to less experienced engineers.Join Our Talent Community
