Overview

Aerojet Rocketdyne is seeking a Specialist Engineer/Ballistician to join our Huntsville, AL office. With minimal direction, you will apply technical expertise to directly contribute to the development of new concepts and techniques. This position exercises considerable latitude in determining objectives and approaches to assignments.

 

As a Specialist Engineer, your expertise in combustion, grain design and performance analysis of solid rocket motor and igniter propellant grains will be utilized. In conjunction with program requirements, develops the motor preliminary designs through a series of trades for the optimum system solution. Develops methodologies and models for the performance prediction of sub and full scale solid rocket motor test firings and conducts subsequent post firing correlation analysis. Evaluates post fire analysis data for rocket motor combustion characteristics. Prepares inputs for Engineering Drawings and Specification Documentation relating to solid rocket propellant grains and dispositions loaded motor and/or propellant related issues. Coordinates pertinent design requirements for solid motor grains with manufacturing personnel and assists in the definition of associated tooling and manufacturing processes. Evaluates material obsolescence issues related to propellant and motor performance.

Essential Job Functions (Including % of Time for Each)

55% - Perform ballistic modeling activities:

  • Perform trades for grain design that meet performance requirements.
  • Conduct grain design, performance analysis, pretest predictions with established methodologies for motor test firings.
  • Conduct post firing data correlations and/or burning rate analysis with established methodologies.
  • Analyze ballistic and propellant data for model updates.
  • Prepare technical reports and presentations documenting all activities.

35% - Continuous Improvement activities:

  • Update current or proposed ballistic models/methodologies to improve technical fidelity and/or design cycle time.

10% - Design and Manufacturing Support:

  • Prepare inputs for engineering drawings and specifications relating to solid rocket propellant grains. Coordinates design requirements of these grains with manufacturing personnel.

Requirements

Requires a Bachelor's degree in Engineering (Mechanical, Aerospace or Chemical Engineering) and at least 9 years of engineering experience with solid rocket motor design and/or analysis or an equivalent combination of experience and education.

 

Additional Requirements:

  • US Citizenship required. Must be able to obtain and maintain a U.S. Security Clearance at the appropriate level (U.S. Citizenship required). Must also be able to satisfy federal government requirements for access to government information, and having dual citizenship may preclude you from being able to meet this requirement.

  • Demonstrated experience in performing design and/or analysis of solid rocket motor propulsion systems is required.
  • Requires proficiency using ballistics models, SPP (or equivalent).
  • Proficiency in Microsoft Office products (Word, Excel and PowerPoint) is expected.

Preferred Qualifications:

  • A Master's or Doctorate degree in a field of engineering that relates to solid rocket motor phenomenology is preferred.
  • Knowledge and experience with aerospace product development efforts is desired.
  • Experience in software development is a plus.

 

Work Environment and Physical Requirements:

Employees in these positions must possess mobility to work in a standard office setting and to use standard office equipment, including a computer; stamina to sit or stand and maintain attention to detail despite interruptions; may occasionally lift/carry/push/pull up to 25 pounds; may require occasional walking, climbing, stooping, crouching, and/or bending; and vision to read printed materials and a computer screen, and hearing and speech to communicate in person and over the telephone. May require the ability to travel by air or auto. May require the use of personal protective equipment such as safety glasses, safety shoes, and shop coat. These positions may be expected to work varying shifts and hours to ensure successful operation of activities in the organization.
