You will be responsible for the strategic direction, technical quality, and regulatory compliance of multiple projects while mentoring junior and mid-level staff. Your role will involve working closely with senior management, clients, and stakeholders to ensure projects are delivered on time, within budget, and in full compliance with environmental regulations.

We are open to having the candidate work from any location within the US Mainland, in what is our preferred work model of a hybrid basis, but we are open to candidates working 100 percent remotely, depending on their current location within the US.  We are also flexible to part time OR full time roles as well.  Whatever situation fits your needs/wants best.

• Regulatory Oversight & Compliance Management:  Ensure compliance with federal, state, and local environmental regulations, including CERCLA, RCRA, and other applicable environmental laws. Lead regulatory negotiations, prepare high-level reports for regulatory agencies, and manage the permit and approval processes for complex remediation projects.
