Aerojet Rocketdyne is a world-recognized aerospace and defense leader providing propulsion and energetics to its space, missile defense, strategic, tactical missile and armaments customers throughout domestic and international markets.

Aerojet Rocketdyne offers a complete line of propulsion products for launch vehicles, missile defense, and advanced hypersonic propulsion.

Aerojet Rocketdyne seeks a Sr. Mechanical Design Engineer to join our engineering design team in our Canoga Park location. This position requires mechanical design skills that will be applied in designing and solving issues in the development and integration of high pressure and extreme temperature Mechanical Engineering hardware; such as Injectors, Igniters, Combustion Chambers, and Nozzles, for large liquid rocket engines. Working under the guidance of senior staff and subject matter experts, the candidate will support and produce the innovative designs and design changes necessary to be used in these high pressure, extreme environment applications.


This position may be filled at this level or one level higher

Essential Job Functions (Including % of Time for Each)

The selected candidate will perform mechanical design engineering assignments requiring application of advanced engineering principles, theories and concepts to develop propulsion hardware for spacecraft and missile programs.


50% - Perform design tasks that create mechanical design components and their higher level systems for high pressure and extreme environment applications. Interpret engineering models and drawings and perform tolerance studies. Evaluate technical input from hardware suppliers and work with cross functional teams on producibility improvements and cost savings. Candidate will participate in trade studies and preliminary designs using 3D CAD modeling software tools.


20% - Performs or coordinates thermal and structural analysis for predicting component and system level performance in the design of the products. Interacts with manufacturing to assure hardware is producible.


20% - Prepares engineering drawings with associated geometric dimensioning and tolerancing in accordance with ASME Y14.5 standards. Actively participates in team meetings to assure design content for new or modified engineering designs. Prepares CAD files for team approval and monitors design release.


10% - Prepare presentations for internal and external customers. Responsible for preparing engineering reports to support tolerance studies, engineering analyses, or failure investigations, including technical close-out reports.


  • A Bachelor's degree in Mechanical Engineering, or an appropriate discipline, and five (5) years of directly related experience, or an equivalent combination of education and experience.
  • An advanced degree or coursework toward an advanced degree is a plus.
  • Working knowledge of CREO Pro-Engineer CAD geometry-based modeling is desired.
  • Experience in the design and development of mechanical systems and working knowledge of ANSI Y14.5 is desired.
  • Strong mechanical engineering background with knowledge and understanding of fluid flow principles.
  • Experience with aerospace hardware is beneficial.
  • General component and system level knowledge of rocket propulsion hardware is desirable.
  • General understanding of manufacturing processes (welding, brazing, machining, heat treating) is necessary.
  • Proficient with Microsoft Office products (Word, Excel and Power Point) is also needed.
  • US Citizenship required. Must be able to obtain and maintain a U.S. Security Clearance at the appropriate level (U.S. Citizenship required).
