• Coordinate studies involving wetlands, waterways, threatened and endangered species, cultural resources, hazardous materials, noise, agricultural resources, and other applicable environmental considerations.
• Conduct or support field investigations, environmental assessments, sampling, monitoring, and data collection.
• Coordinate with clients, transportation agencies, regulatory agencies, engineers, planners, scientists, and other technical specialists.
• Support Section 4(f) evaluations, environmental commitments, mitigation tracking, public-involvement activities, and project meetings.
• Develop and manage scopes, budgets, schedules, and assigned tasks while meeting project deadlines and quality requirements.
• Direct or coordinate tasks completed by other technical and field staff.
• Support environmental work for transportation, energy, and other infrastructure clients based on project needs.

Required

• Bachelor's degree in environmental science, environmental studies, biology, ecology, natural resources, environmental planning, or a related discipline.
• 10+ years of relevant environmental experience, including qualifying internship experience.
• Professional experience supporting environmental review and clearance under the National Environmental Policy Act.
• Experience preparing or contributing substantively to NEPA documents and supporting technical studies.
• Understanding of the environmental-clearance process for transportation or comparable infrastructure projects.
• Ability to independently manage defined assignments, identify environmental requirements, and coordinate work across multiple disciplines.
• Strong technical writing, research, organization, communication, and computer skills.
• Ability to perform office and field assignments and travel to project sites and meetings.
• Valid driver's license and ability to meet RETTEW's requirements for operating a company vehicle.
• Ability to perform the essential functions of the position with or without reasonable accommodation.

Preferred

• Experience supporting NEPA clearance for transportation projects.
• Experience working with PennDOT, the Federal Highway Administration, the Pennsylvania Turnpike Commission, or comparable transportation agencies.
• Experience preparing categorical exclusions, environmental assessments, environmental impact statements, reevaluations, or Section 4(f) documentation.
• Experience with wetland, waterway, ecological, cultural-resource, or related environmental studies.
• Experience submitting Chapter 105 permits in PA GreenPort and Keystone Environmental ePermitting System.
• Experience organizing and participating in public involvement activities.
• Professional Wetland Scientist certification or OSHA 40-Hour HAZWOPER training.
• Section 4(f) experience is helpful but is not required at the time of hire.[ES1.1]

Why RETTEW

• Help transportation and infrastructure projects move forward responsibly.
• Take meaningful ownership of environmental-clearance assignments.
• Work with clients, agencies, and multidisciplinary technical teams.
• Expand your experience across NEPA, Section 4(f), environmental studies, and regulatory coordination.
