An advanced degree is strongly preferred. * Minimum 15 years of experience leading ecological risk assessments under CERCLA and/or RCRA regulatory framework, or highly relevant related experience. * Demonstrated understanding of ecological risk assessment concepts, including the scientific basis of media-specific screening values, parameters that impact bioavailability, and site-specific evaluation of toxicity and bioaccumulation. * Experience with PFAS chemicals is highly preferred. * Exemplary technical writing and verbal communication skills. * Excellent critical thinking, deductive reasoning, and problem-solving skills. * Attention to detail. * Solution-oriented mindset. * Experience in terrestrial and aquatic ecosystems. * Familiarity with specialized federal law (e.g., Endangered Species Act, Wetlands Regulations) is a bonus. * Understanding multiple state and federal regulatory frameworks is a plus.
