Scientist II Gas and Material Science Laboratory

Applies professional scientific knowledge and techniques research or testing programs.  Performs well-defined experiments to studies of a complex nature within a specific scientific discipline.  The Scientist II is responsible for completing tasks, solving most of the associated technical problems independently, and may be required to coordinate the assignment with others working on related phases of a problem.  Must use judgment to evaluate and adapt laboratory requirements/guidelines to customer specifications and testing needs.  Because of the critical nature of the support provided, extended working hours (including weekends and holidays) are often mandatory.     

Job Duties and Responsibilities (Essential Functions)

The Scientist II  Gas and Material Science Laboratory operates with a degree of independence under established policies and procedures. Normally receives sufficient guidance from Laboratory Lead, Scientist IV and/or Scientist III to assure coordination of efforts with other personnel working on related phases of the program.  Maintains infrequent technical liaison with customers, their representatives, and contact with other laboratory professional/scientific personnel. Knowledge of chemical principles, theories, practices, and established methodology in performing lab analyses with emphasis on gas and materials testing ( e.g, failure analysis of metals).    Responsible to identify unknown materials / contaminants associated with rocket engine and propulsion systems.  Applies professional scientific knowledge and techniques to the investigation, study, analysis, and reporting of testing samples or research programs.  Performs well defined experiments or studies ranging from simple to moderate complexity.  Must be competent in the use of computer and computer software.  May be required to coordinate their assignment with other laboratory scientists. 

Successful candidates for this position will have:

In depth experience using Scanning Electron Microscopes, X-ray and IR spectrometers, Gas Chromatographs and Material / Mechanical Testing equipment (e.g., hardness, tensile strength, etc.,). Knowledge and experience to determine root cause failure of hardware - strong problem solving skills and able to work independently as well as in a team setting - capable of handling multiple projects and meeting deadlines (e.g. unplanned overtime). The ability to analyze and monitor trace levels of gaseous contaminants in propellant and pressurant systems. Develops analytical methods and techniques for gas and cryogenic analysis. Utilizes various lab equipment to conduct gas analysis for rocket propulsion testing that includes ( paramagnetic and zirconium O2 analyzers for O2 purity determination, electrochemical fuel cells for measuring trace oxygen levels, non-dispersive hydrocarbon analyzers for CO and CO2 determination, flame ionization analyzers for measuring volatile hydrocarbons, gas chromatographs equipped with TCD and Helium Ionization detectors for separating and measuring low concentration of gas components in permanent gases including para and ortho hydrogen) These techniques may involve adaptation or modified techniques to new situations, or new approaches. Must be able to setup new analytical processes and analyze various fluid samples ( e.g. natural gas analysis for H2S, mercaptans, purity determination,  GN,   hydraulic fluids for impurities using X-Ray spectroscopy.) Excellent written, verbal, and interpersonal communication skills - to effectively extract and analyze data to generate comprehensive technical and failure analysis reports. Efficient computer skills, including knowledge of the Microsoft software suite – image processing (combining and editing multiple image signals) Successful history of performing maintenance and inspections on lab equipment.

Major Duties:

Performs professional assignments within a specific scientific discipline.  Applies scientific knowledge and methodology to experiments or studies designed to yield solutions to testing or development problems.  Pursues investigations into new or promising scientific fields, to assess their applicability to existing programs or potential areas of company activities. Evaluates, and implements process plans and methods for techniques suitable for day-to-day use on a routine basis.  These techniques may involve adaptation of classical techniques to new situations, or new approaches.  Performs assignments independently or with others under general guidance from higher-level scientists or management. Receives technical guidance on unusual or complex problems. Change out k-bottles as needed. Participates in providing innovative approaches to technical problems, contributes to the overall increase in lab efficiency through adaptive thought and information exchanges. Guides and trains assigned personnel as required and advises supervisory personnel of their progress. Reviews the results of tests in relation to the reliability, completeness, and accuracy of the test and methods employed.  Submits dispositions relative to the results of this analysis. Performs light repairs, maintenance, and preventive maintenance on complex equipment as necessary to keep in good stable working condition. Consults on matters relating to an acquired scientific specialty.  Participates in resolving technical problems and collaborates with colleagues in methods development and validation. Assist other departments when required. And all other duties as assigned.
