Job Summary
We are looking for a senior Propulsion Engineer to serve as the Subject Matter Expert and team lead for propulsion systems on next-generation hypersonic and missile programs. The ideal candidate will architect clean-sheet designs, perform and oversee propulsion analysis, develop manufacturing and test processes, and deliver flight-ready systems that include solid rocket motors, cold-gas systems, and mono- and bi-propellant reaction control systems. This position demands extensive hands-on experience and the ability to lead a team through design, integration, and test under demanding schedules.

Responsibilities

• Architect and design clean-sheet propulsion and reaction control systems using a lean requirements approach.
• Create detailed 3D models, assemblies, and technical drawings to support manufacturing and integration.
• Perform and lead propulsion analysis for solid, cold-gas, mono-propellant, and bi-propellant systems.
• Develop processes and procedures for manufacturing, integration, and testing of propulsion systems.
• Develop integration and test plans for hardware-in-the-loop (HWIL) propulsion systems.
• Select and source propulsion components from both traditional and non-traditional suppliers.
• Lead a team through design, build, test, and delivery of propulsion systems to customers on accelerated timelines.
• Collaborate with multidisciplinary teams to ensure seamless integration of propulsion systems into hypersonic and missile platforms.

Basic Qualifications

• Active DoD Secret Clearance required
• Work in person at our corporate headquarters in Huntsville, AL.
• One of the following:
  • Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related field with relevant industry experience
  • Master’s degree or Ph.D. in Mechanical Engineering, Aerospace Engineering, or a relevant field with experience applying knowledge to real-world systems
• A minimum of 20 years of industry experience in propulsion systems for aerospace or defense applications.
• Strong proficiency in cold-gas systems, water hammer analysis, and solid rocket systems.
• Hands-on experience with thermal analysis tools such as Thermal Desktop.
• Demonstrated experience testing various propulsion systems.
• Knowledge of the current U.S.-based propulsion supply chain.
• Excellent problem-solving skills and attention to detail.
• Strong communication and leadership skills to lead multidisciplinary teams.
• Experience with aerospace regulatory standards and certification processes is a plus.

Preferred Qualifications

• Knowledge of Missile Defense Agency (MDA) requirements and processes.
• Familiarity with Finite Element Analysis (FEA) for coupled thermal-structural simulations.
• Knowledge of high-temperature materials (ceramics, composites, ablative coatings) as they relate to propulsion systems.
• Experience in high-temperature testing or simulation of aerospace components.
• Understanding of orbital mechanics and space environment effects on propulsion systems.

What we offer

• The opportunity to lead development of next-generation hypersonic and missile propulsion systems with real-world impact.
• A collaborative and fast-paced work environment with passionate engineers.
• Top-tier salary and benefits package.
• Continuous learning and growth opportunities.
