• Actively collaborate with the Navy CLEAN PFAS SME team through participation in routine meetings and engaging with other PFAS SMEs to support project teams.

• Develop and review PFAS approaches for CERCLA Remedial Investigations, expedited drinking-water evaluations, removal actions, pilot studies, and long-term site-management decisions.

• Evaluate PFAS occurrence, fate and transport, release mechanisms, co-mingled releases, preferential pathways, hydrogeology, surface-water/sediment interactions, and potential off-installation impacts.

• Plan and review sampling and analysis plans, field procedures, laboratory and data-validation requirements, data usability evaluations, and technical reports.

• Support background studies, including evaluation of PFAS sources, geographic or hydrogeologic grouping, sampling design, statistics, and risk communication.

• Provide technical oversight of field investigations, subcontractors, health and safety, quality requirements, and issue resolution.

• Participate in stakeholder meetings; support comment resolution and client-ready recommendations.

• Support community-facing work involving private drinking-water sampling, public meetings, risk communication, notifications, and communication of results to property owners and other stakeholders.

• Use Microsoft Teams, Outlook, SharePoint, and Microsoft Office tools to coordinate distributed teams, manage meetings and action items, maintain document control, and communicate status promptly.

• Mentor staff, share lessons learned, promote consistent technical practices, and contribute to proposals, technical papers, training, and business development.

• Bachelor’s degree in environmental engineering, civil engineering, geology, chemistry, environmental science, or related discipline.

• At least 10 years of progressively responsible technical experience in environmental consulting, investigation, remediation, or related federal-program work, including substantial PFAS experience.

• Strong PFAS technical competency, including ability to interpret analytical data and connect results to release history, conceptual site models, fate and transport, exposure pathways, and response decisions.

• Demonstrated experience leading or supporting remedial investigations or similar delineation investigations

• Strong experience working across multidisciplinary teams, including technical staff, project managers, and regulators.

• Experience preparing or reviewing work plans, sampling and analysis plans, reports, figures, tables, and regulatory response documents.

• Experience coordinating technical teams, subcontractors, deliverables, schedules, quality requirements, and issue resolution.

• Strong written, verbal, facilitation, and interpersonal communication skills, including communication with nontechnical audiences.

• Proficiency with Microsoft Outlook, Teams, Word, Excel, PowerPoint, SharePoint, and related collaboration tools.

• U.S. work authorization and ability to meet applicable Navy, Jacobs, and contract access or background-screening requirements.

Ideally, you’ll also have:

• Professional Engineer registration or another relevant professional certification.

• Demonstrated working knowledge of the CERCLA framework and its application to investigation, risk, regulatory, and site-management decisions.

• Experience leading multi-installation or nationwide PFAS projects, background studies, drinking-water investigations, removal actions, or pilot studies.

• Demonstrated experience leading or supporting remedial investigations and background studies for DoD or Navy environmental programs.

• Experience with PFAS data validation, EPA Method 1633, data usability, statistics, geospatial analysis, dashboards, or PFAS fingerprinting.

• Experience with public outreach, risk communication, Restoration Advisory Boards, or coordination with health departments and local governments.

• Experience mentoring technical staff and establishing consistent program procedures across projects.
