1d•$95,000 - $115,000•Hybrid

About The Position

Barr is seeking a senior environmental toxicologist to support complex, multidisciplinary projects involving contaminated sediment, surface water, groundwater, and ecological risk assessment. The role includes conducting ecological risk assessments; developing toxicity and exposure evaluations for contaminated sediment projects; interpreting environmental chemistry and toxicology data; preparing technical reports, study designs, sampling plans, and quality assurance documentation; and contributing to work conducted under CERCLA, RCRA, NEPA, NRDA, and other federal and state environmental programs. The position applies advanced environmental toxicology principles to evaluate chemical exposure and effects across sediment, water, and biological systems and to support remedial decision-making. The successful candidate will lead or support project and task delivery, develop scopes, schedules, and budgets, manage teams, prepare technical documents, and build client relationships. The role also involves developing scientifically defensible approaches aligned with applicable regulatory programs, communicating complex concepts to technical and non-technical audiences, collaborating with multidisciplinary teams and clients, and mentoring junior staff. The position may be based in Barr's Seattle, Washington, or Denver, Colorado, office, with a hybrid work arrangement potentially available. Travel and periodic schedule adjustments may be needed to meet project needs. Fieldwork may be available depending on project needs, interests, and experience, and may involve out-of-town travel. Work may take place outdoors on rough terrain, at construction or waste-disposal sites, at hazardous-material cleanup sites, and in industrial facilities with limited accessibility or moving machinery. An OSHA-mandated physical exam may be required; safety training will be provided, and specific clients may request participation in a drug-screening program. Candidates must be able to perform job duties with or without reasonable accommodation. The anticipated annual compensation range is $95,000–$115,000, varying with relevant experience, education, skill level, and other compensable factors. Employees may also be eligible for a discretionary cash bonus based on team and individual performance. The role is classified as exempt (salaried) under the Fair Labor Standards Act.
