• Anticipate, identify, and mitigate project risks through proactive planning and technical problem-solving.
• Provide clear, persuasive communication to regulatory partners, community groups, and executive leadership.
• Act as a strategic advisor on project direction, regulatory matters, and engineering decisions.

What You Bring

• Bachelor’s or Master’s degree in Environmental Engineering, Geology, Environmental Science, or related field.
• 10+ years of progressive environmental project management experience, including CERCLA/Superfund or complex remediation projects.
