Precise Systems seeks an Analytical and Physical Chemist with 3-5 years of experience in determining the environmental fate of chemicals. This position supports the initial hazard assessment of emerging hazardous and toxic compounds by evaluating stability, transport and partitioning, degradation, persistence, physical, and chemical properties. The incumbent may also assess the environmental impacts, and hazards associated with toxic materials following dissemination or environmental exposure.

Experience with thermal desorption, pyrolysis, gas chromatography (GC), gas chromatography mass spectrometry (GC-MS), liquid chromatography mass spectrometry (LC-MS, and liquid chromatography mass spectrometry-mass spectrometry (LC-MS-MS) a plus. This position requires an emphasis of the chemical analysis of toxic compounds and their extraction from environmental samples. The role requires dedicated problem-solving, keen attention to detail, and a strong foundation in general laboratory skills.

The successful applicant will possess a demonstrated aptitude for working both independently and in collaboration with other team members, as this position supports many scientists across the center, including chemists, biologists, chemical engineers, and material scientists.

This role requires in-person support.

• Support new and ongoing research programs as a technical lead and research team member to meet program goals and objectives.
• Routinely perform instrumental analysis and testing and controlled environmental-exposure experiments of known and suspected toxic compounds.
• Analyze samples from a range of matrices—including vapor, soil, water, and tissue—for target compounds and degradation products using analytical instrumentation and methods such as:
• Thermal desorption
• Pyrolysis
• Gas chromatography with flame photometric detection (GC-FPD)
• Gas chromatography-mass spectrometry (GC-MS)
• Liquid chromatography-mass spectrometry (LC-MS)
• Tandem liquid chromatography-mass spectrometry (LC-MS/MS)
• Determine and evaluate chemical physical properties, including vapor pressure, solubility, density, viscosity, surface tension, flash point, thermal stability, partition coefficient, and acid dissociation constant.
• Develop, revise, and maintain laboratory procedures (IOPs), SOPs, test plans, research documentation, and technical reports.
• Support laboratory management activities, including equipment and supply inventory, chemical tracking, waste-disposal coordination, and maintenance of laboratory procedures and records.
• Prepare monthly progress reports and maintain routine communication with program customers, stakeholders, and internal technical teams.

• Ph.D. in Chemistry, Environmental/Chemical Engineering, Biology, Biochemistry, or a closely related field.

• 3-5 years of practical laboratory experience.
• Hands-on experience utilizing vapor pressure…
