Environmental Engineering Intern

At RES, we’re looking for purpose-driven individuals who are passionate about restoration and sustainability, and who want their work to make a lasting environmental impact. Our team members go above and beyond, bringing initiative, integrity, and a strong work ethic to every project. Collaboration is key—we thrive on teamwork, open communication, and diverse perspectives. In a field that constantly changes, we value those who are resilient, adaptable, and resourceful in the face of challenges.

If you're intellectually curious, eager to learn, and ready to help restore ecosystems and protect natural resources, you’ll find your place here.

At Resource Environmental Solutions (RES), the largest ecological restoration organization in the U.S., environmental engineering interns gain hands‑on experience solving real-world challenges.

• Real‑World Impact: Work on transformative projects restoring wetlands, streams, and habitats while improving water quality and resilience.
• Hands‑On Learning: Apply skills in hydrology, geomorphology, and environmental modeling alongside expert engineers and scientists.
• Professional Growth: Collaborate with multidisciplinary teams, gain mentorship from industry leaders, and develop technical and leadership skills.
• Purpose‑Driven Work: Be part of a company dedicated to sustainability and building a better future.

With operations in 9+ regions across the U.S., RES leads in comprehensive solutions for wetlands, streams, species habitats, and water quality improvements.

RES is looking for driven Environmental Engineering Interns to support our design and engineering team in our Warrenton, VA offices. This role offers you the chance to apply your academic knowledge to impactful projects, focusing on practical applications in ecological restoration, hydrologic and hydraulic modeling, and environmental sustainability.

As an intern, you’ll collaborate with experts across engineering, ecology, and GIS (Geographic Information Systems) teams to gain insights into the integration of ecological design and restoration practices. Your contributions will directly support projects that enhance ecosystems, protect resources, and drive sustainable outcomes.

• Diverse Learning Opportunities: From data analysis and fieldwork to design support, you'll tackle various tasks that deepen your technical and problem‑solving skills.
• Mentorship and Teamwork: Partner with experienced design/engineering professionals who are eager to guide you through real‑world challenges and help you build a foundation for your career.
• Second‑Year Advancement: Returning interns will take on more advanced responsibilities, including exploring regulatory frameworks, completing detailed hydrologic and hydraulic models, preparing construction design plans, contributing to project task management, developing cost estimates and proposals, and applying value‑engineering principles.

This full‑time internship typically runs from May to August (specific dates to accommodate student’s school schedule) and is designed for motivated individuals seeking to make a tangible impact in ecological restoration.

As an Environmental Engineering Intern, your responsibilities will encompass a dynamic mix of fieldwork, data analysis, and design support. By the end of the internship, participants will have assisted with the development of ecological restoration designs and the preparation of components of technical reports. In addition, participants will deliver a presentation summarizing their experiences and contributions during their internship.

Field Surveys and Data Collection: You will collect essential data on stream flow, in‑stream habitat, bank erosion potential, cross sections, longitudinal profiles, and stream bed material. Using GPS, laser levels, and total stations, you’ll conduct stream surveys to support post‑restoration monitoring or…
