Job Description

SIMETRI Inc. is currently looking for a Senior Scientist III in Chemistry who is passionate, hardworking, and will work with the Environmental Chemistry Branch, Environmental Processes and Engineering Division at the Environmental Laboratory, US Army Engineer Research and Development Center. The candidate will execute the research, development, and evaluation tasks including fabrication and instrumentation of test articles; coordination and conduct of major field investigations; theoretical studies; and laboratory experimental work and computational modeling. They will provide scientific and technical guidance and coordination among contractors and communicates scientific and technical information through oral briefings and written documents. Has the ability to supervise associate contractors and works beside them in their daily operations and research in analytical chemistry, material chemistry, and computational chemistry. The ideal candidate is familiar with a variety of the field’s concepts, practices, and procedures and relies on extensive experience and judgment to plan and accomplish goals.

Duties and Responsibilities include the following. Other duties may be assigned.

  1. Conducts analytical chemistry research on contaminants and other materiel in a variety of matrices including water, soils, sediments, solids, liquids, and tissues.  Have the ability to extract samples and analyze, collect and report data and provide all sample custodian tasks and maintain laboratory equipment.
  2. Conducts Routine inorganic and organic analyses such as Metals extractions, digestions, TS/TSS/Turbidity, P-FAS/P-FOS, (Polyaromatic Hydrocarbons (PAHs), Organochlorine and Organophosphorous Pesticides and Lipids) and complex analytes (such as Polychlorinated Biphenyls (PCB Arochlors and Congeners) requiring a typical 30 day turnaround time (90 days for congeners) utilizing standard methods.
  3. Performs matrix clean-up and interference reduction procedures to reach project specific reporting limits including the below procedures:
    1. Gel Permeation Chromatography (GPC)
    2. Fluorosil and Silica Gel clean-up columns
    3. Sulfur removal via mercury or TBA methods
    4. Acid treatment
    5. Dilution should only be used as an interference reduction technique as a method of last resort after approval from the project manager or team leader. Dilution is generally only used for analytes that are above the analytical calibration range.
  4. Analyzes, collect, and report instrument data for routine and complex organic analyses; troubleshoot, calibrate, and maintain instruments.
  5. Has previous experience using lab instrumentation such as: GC-MS, LC MS, Fluorescence, Ion Chromatography (IC), colorimetry, nephelometry, potentiometry, High Performance Liquid Chromatography (HPLC), Gas chromatography  (GC), Inductively coupled plasma atomic emission spectroscopy (ICPAES), and  Inductively coupled plasma mass spectroscopy (ICPMS) to extract and analyze environmentally relevant contaminants, elements, and compounds from a variety of matrices.
  6. Experience following EPA SW-846 guidelines, modifications of EPA guidelines, and the ability to follow project-specific Sampling and Analysis Plans (SAP) and Quality Assurance Project Plans (QAPP) for all analyses including appropriate QA/QC and analyte reporting limits.
  7. Experience performing basic and routine calibration, cleaning and maintenance, replacement of consumables, and troubleshooting of scientific instruments as well as the recording of information about calibration, maintenance, and troubleshooting in an instrument logbook.
  8. Experience Developing, modifying, applying, and executing analytical chemistry research and apply modified methods to organic projects; develop, define, and document methodology for analysis of emerging contaminants and in complex matrices; and collect and analyze data from instrumentation and perform routine equipment maintenance.
  9. Conduct analytical chemistry research, including method modifications, on contaminants, compounds, and other materials related to the USACE mission delivered in a variety of matrices, including water, soils, sediments, solids, liquids, and tissues.
  10. Develop, define, and document new or modified analytical methods for determining the concentration and types of emerging contaminants (EC) and/or other analytes at different concentration limits in a range of matrix types, including water, sediment, soil, and tissue. The methods development should include an application for laboratory instruments or rapid field screening techniques and include all relevant QC and documentation. The analysis methods used must meet the needs of the customers and stakeholders in terms of detection limit, time for analysis (generally 30-90 days), resources and instrumentation needed, and validation required. All regulatory requirements must be met. Analyses for a variety of emerging contaminants will be performed as needed.
