  • Overview

    Sierra Lobo, offers customers a full range of professional and technical capabilities, including Test and Evaluation, Systems Engineering, and Advanced Technologies.  We also develop products and processes related to Cryogenic Fluid and Thermal Management Systems, Densified Propellant Management Systems, and Prototype Extreme Pressure and Temperature Systems.  Our customers include the Department of Defense (DoD), the U.S. Air Force, U.S. Navy, U.S. Army, Missile Defense Agency (MDA), and the National Aeronautics and Space Administration (NASA).


    This position is located on the ETIS II contract at NASA’s Goddard Space Flight Center, Greenbelt Maryland.







    Works under supervision of the Chemical Analyst Manager and Contamination Control (CC) Supervisor and continues to build on skills and abilities in chemical analysis, CC, and cleanroom materials/processes.
    Will provide intermediate level of expertise in performing chemical analysis, utilizing instrumentation for the identification and reporting of organic compounds and chemical species related to contamination studies (routine or investigative). In addition, will provide cleanroom/CC support and intermediate level of expertise in materials/processes review and approval of consumables materials, cleanroom garments, and usage of industrial/commercial/aerospace grade materials in contamination sensitive areas.
    The goal is to evolve into a senior engineer expertise level in chemical analysis, CC, and cleanroom materials/processes.



    1. Obtain routine sampling for chemical analysis support such as swabs, wipes, solvent rinses, or direct material identification. Sampling may be from direct spacecraft components, critical ground support equipment, consumables, garments, proposed cleanroom materials, foreign object debris (FOD), or unknown contaminants from any surfaces encountered. Have the ability to train personnel on sampling techniques.
    2. Perform sample preparation for Fourier Transform Infrared (FTIR) Spectroscopy and Gas Chromatography-Mass (GC-MS) Spectrometry operation. Have the ability to train personnel on FTIR and GC-MS sample preparation techniques.
    3. Operate the FTIR and GC-MS instrumentation for obtaining chemical analysis data, either routine or investigative, to support CC studies.
    4. Ability to perform calibration/tuning and in-house maintenance of the FTIR and GC-MS instruments.
    5. Ability to interpret (intermediate level) FTIR spectral and GC-MS chromatographic/spectral data and report findings to CCL Manager, project personnel and customers of all departments.
    6. Ability to convey/report findings from chemical analysis for assisting in identifying contamination sources and providing recommendations to mitigate contamination infiltration and general consulting on CC issues.
    7. Ability to create chemical analysis reports to project personnel and various customers in written form.
    8. Ability to review, write and maintain documentation for the CC Department.
    9. Provide support in all aspects of CC facilities including, but not limited to, molecular and particulate cleanroom monitoring, off-gassing/out-gassing effects in contamination sensitive areas cleanrooms and thermal vacuum testing chambers or ovens, witness foil and witness plate deployment/monitoring, and review/approval of proposed materials for cleanroom use
    10. Participate on a Materials Review Board team which specializes in review/approval of proposed materials/processes for cleanroom usage/build, providing any required chemical analysis, materials expertise, or materials test recommendations.
    11. May also perform temporary duties in other areas or other duties associated with area of assignment.
    12. May also perform Lab Management initiatives as it relates to contamination control.


    1. Selects and incorporates the proper methods of chemical analysis in order to support spacecraft project requirements and customer’s CC concerns.
    2. Accurately reports chemical analysis data and findings and is able to resolve contamination issues.
    3. Reviews, analyzes and integrates the technical work created in the laboratory and creates and maintains databases for all pertinent data collected.
    4. Capable of developing stronger skill sets to achieving a goal of senior engineer/analyst level expertise.
    5. Ability to adapt to weekend and holiday support on short notice and extended hours as required.
