Expertise in statistics, environmental fate modeling, field sampling, human health risk assessment, and population ecology or field biology a plus. Must possess solid technical and communication skills and be capable of designing, writing, and coordinating reports on all size projects. Position requires MS/PhD in environmental sciences or engineering.



Environmental Chemist

Rewarding opportunity for an environmental chemist to provide technical support and critically review, analyze, and interpret laboratory data and provide data quality assurance/quality control (QA/QC) oversight. Knowledge and experience with data validation of both inorganic and organic data is preferred. Must possess solid technical and communication skills and be capable of designing, writing, and coordinating reports on all size projects. Position requires a minimum of a BS or MS in environmental sciences or chemistry. Prior environmental laboratory and/or consulting experience desired.



Environmental Air Modeling Scientist/Engineer

Excellent opportunity for experienced scientist or engineer with strong air modeling capabilities. Candidates should be proficient with industry standard air models, and be capable of applying them creatively to a wide range of environmental project work: source emission characterization, environmental forensics, air dispersion, multi-media risk assessment, toxic torts, accidental releases, vapor intrusion/indoor air, and air permitting. The ideal candidate will also possess a multi-disciplinary skill set with demonstrated abilities in one or more of the following areas: environmental site assessment, data analysis tools (including statistics), site remediation, and the ability to model chemical fate & transport in other media. Candidates must have excellent writing and oral communication skills, as well as exceptional quantitative skills. An advanced degree and demonstrated experience are required.


Qualifications for this position include:

  • Masters or Doctorate degree in a relevant engineering or scientific discipline;
  • 2-3+ years consulting experience;
  • Strong scientific or engineering background related to air modeling;
  • Working knowledge of industry standard air models such as AERMOD, MOBILE6.2, CALPUFF, RPM-IV, VISCREEN, and PLUVUE;
  • Excellent written and oral communication skills;
  • Understanding of CAA and other relevant regulations – a plus.


Senior Toxicologist/Risk Assessor

Seeking driven, high energy individual to assist colleagues and clients by applying knowledge of toxicology and human health risk assessment. Requires statistical skills and data management experience. Project work will include litigation support, regulatory comment, product safety assessments, and site-specific human health risk assessment. Position requires M.S./Ph.D. in toxicology, environmental health, or related field. Candidates must have excellent writing and quantitative skills, and the ability to work independently in a challenging and fast-paced work environment. Requires at least two years prior consulting experience, including managing projects with multiple staff.



Epidemiologist/Toxicologist

Focus on environmental and human health risk assessment issues by performing epidemiology, toxicology, and statistical analyses for interesting, science-based evaluations. Enjoy technically-challenging work for projects that involve regulatory comment, litigation support, product safety assessments, and human health risk assessment. Position requires M.S./Ph.D. in epidemiology, environmental health, toxicology, or related field as well as strong organizational and written communication skills. Applicants must have strong statistical skills and the ability to critically evaluate epidemiology data. Prior consulting experience and knowledge of environmental regulations, air modeling, and other exposure assessment techniques a plus.
