What You'll Do

• Perform design, analysis, and development of rocket motor and pyrotechnic articles.
• Conduct in-depth data and performance analysis with a focus on iterative design and improvement.
• Prepare technical reports, qualification matrices, and compliance documentation in alignment with military and aerospace standards.
• Develop tools and methodologies for the analysis and performance estimation of our rocket motors.
• Support the development of Thermal Protection Systems (TPS), nozzle, and rocket motor sizing tools.
• Assist in the design and certification of rocket motors in accordance with MIL-STD and STANAG standards.
• Collaborate closely with design engineers on motor hardware design, insulation, and igniter integration to ensure certifiability from the outset.
• Support failure investigations, root cause analyses, and updates to design or test procedures to maintain compliance.
• Work with internal teams and external partners to synchronize design validation and certification timelines.

Requirements – What You’ll Need

• A Master’s degree in Aerospace, Mechanical, or Propulsion Engineering.
• A minimum of 4-5 years of experience in rocket motor development.
• In-depth knowledge of design and sizing of rocket motors and thermal protection systems.
