Principal / Senior Principal Engineer – Solid Rocket Motors

At ReLogic Research, you won't be just another headcount. We're a tight-knit team of engineers, physicists, and technical professionals solving some of the most complex challenges in national defense — and we're looking for a Principal or Senior Principal Engineer who is ready to help transition proven solid rocket motor technologies into real programs now.

As an AS9100D-certified small business supporting the Army, Navy, Air Force, and Missile Defense Agency, we move fast, trust our people, and give engineers meaningful ownership of their work. Unlike larger organizations, you won't be buried in a single program — you'll work across multiple efforts simultaneously with immediate technical impact and direct visibility into technology transition.

The feasibility work is done. The technologies are proven. This role exists to take them across the finish line — advancing low-cost alternative solid rocket motor technologies from advanced development into prototype systems, programs of record, and eventual flight.

If you've spent your career in SRM development and are ready to help move propulsion technologies from proven concepts into operational systems, ReLogic is where you belong.

Leveling for this role will be based on demonstrated experience, technical depth, and prior program responsibilities. Exceptional candidates may be considered at either the Principal or Senior Principal level.

Primary Responsibilities

Lead and support technical transition efforts across multiple active solid rocket motor programs simultaneously, advancing proven low-cost alternative SRM technologies into prototype systems and programs of record

Lead and support development and transition of automated propellant casting, automated motor case fabrication, and alternative thermal protection system materials including rayon alternatives

Develop and execute technology transition plans bridging the gap between proven concepts and program insertion

Support small-scale static fire testing at ReLogic facilities including test planning, execution, instrumentation coordination, and post-test data reduction

Support full-scale static fire testing and eventual flight test activities at government or contractor test facilities

Contribute to test plans, procedures, safety documentation, and post-test analysis in support of technology maturation and transition milestones

Provide senior technical leadership across SRM design, manufacturing, integration, and technology maturation activities

Interface with government customers, program offices, and prime contractors to advance technology maturation and insertion efforts

Support proposal development, technology roadmaps, and program planning for SRM-related efforts

Provide technical mentorship and engineering oversight across propulsion-related efforts

Represent ReLogic as a subject matter expert in SRM technology at customer meetings, technical reviews, and conferences

Required Qualifications

BS in Aerospace Engineering, Mechanical Engineering, Chemical Engineering, or related engineering discipline

8+ years of experience in solid rocket motor development, propulsion manufacturing, or a related propulsion field (additional experience required for Senior Principal level consideration)

Demonstrated expertise in one or more of the following:

Energetics and propellant formulation

Motor case fabrication and manufacturing

Thermal protection systems and insulation materials

Experience supporting technology maturation, transition, or insertion efforts in a defense environment

Experience with solid rocket motor static fire testing including test planning, execution, and post-test analysis

Ability to work across design, manufacturing, testing, and program teams to advance technology readiness and operational implementation

Strong written and verbal communication skills including experience presenting technical information to government customers, program offices, or prime contractors

Active Secret security clearance or ability to obtain and maintain a clearance

Must be a U.S. citizen

Preferred Qualifications

MS or PhD in Aerospace Engineering, Mechanical Engineering, Chemical Engineering, or related field

Experience with automated propellant casting or automated composite case fabrication processes

Familiarity with rayon alternative thermal protection system materials and qualification approaches

Experience with JANNAF, MIL-SPEC, or DoD propulsion standards and processes

Experience supporting programs of record insertion or technology transition across TRL 4-7

Familiarity with SBIR/STTR programs or other defense technology development pathways

Experience supporting flight test activities and associated safety and documentation requirements

Experience at or with government propulsion laboratories such as AFRL, DEVCOM, or NASA Marshall

This is a full-time salaried position with highly competitive compensation based on experience and skills, comprehensive benefits, and opportunities for career growth. Approximately 25% travel is expected.
