In this role, you will lead and oversee biological resource assessments, regulatory permitting efforts, and environmental compliance projects across diverse sectors including energy, transportation, utilities, land development, and public infrastructure. You will direct Waters of the U.S. (WOTUS) delineations, jurisdictional determinations, mitigation planning, and protected species habitat evaluations, including focused surveys and regulatory clearances. Responsibilities include preparing and reviewing Biological Assessments (BA), Biological Evaluations (BE), Environmental Assessments (EA), CEQA/NEPA documentation, water quality certifications, sampling programs, monitoring reports, and related environmental compliance documentation.

You will provide senior‑level QA/QC review of technical reports and regulatory submittals while ensuring scientific rigor, regulatory accuracy, and defensible documentation standards.

While primarily operating in a leadership capacity, you will remain actively engaged in field investigations as project demands dictate. This includes conducting or overseeing habitat assessments, wetland delineations, species surveys, compliance monitoring, and sensitive resource evaluations. You will ensure field protocols align with permit conditions and regulatory requirements while maintaining safety standards and data integrity.

You will serve as a primary point of contact for key public and private sector clients, maintaining strong professional relationships and identifying new business opportunities. Responsibilities include leading or supporting proposal preparation, scope development, budgeting, cost estimating, and fee negotiations. You will participate in strategic planning initiatives to expand service offerings and strengthen market positioning while representing the firm at industry meetings, agency coordination sessions, and professional associations.

A core component of this role is maintaining and strengthening relationships with federal, state, and local resource agencies, including the U.S. Fish & Wildlife Service (USFWS), U.S. Army Corps of Engineers (USACE), Bureau of Land Management (BLM), and relevant state wildlife and water quality agencies. You will coordinate permitting strategies, negotiate regulatory pathways for complex projects, and remain current on evolving environmental regulations and policy changes to ensure proactive compliance strategies.

The ideal candidate will hold a Bachelor’s degree in Biology, Ecology, Environmental Science, Natural Resources, or a related discipline (Master’s degree preferred) and bring 10+ years of progressive experience in environmental consulting, natural resources management, or regulatory agency work. Candidates must demonstrate strong technical expertise in WOTUS delineations, species surveys, habitat assessments, and environmental permitting, along with proven experience managing multi‑disciplinary projects.

Established agency relationships, success in client management and business development, experience preparing budgets and proposals, and strong technical writing and QA/QC capabilities are essential. The selected candidate must also be willing and able to participate in fieldwork as necessary to support project execution.

This position offers a rare opportunity to take on a leadership role that balances meaningful, technically complex biological work with strategic influence over business growth and client development. You will have the autonomy to guide project execution, strengthen agency and client relationships, mentor staff, and shape long‑term service offerings within a respected consulting environment.

The ideal candidate values scientific integrity, professional autonomy, long‑term stability, and being part of a firm where their expertise, leadership, and business contributions are recognized and supported.
