As an Application Developer Intern, you can expect to collaborate on real-world projects such as building web or mobile applications, automating business processes, or enhancing existing software. Interns often use languages and frameworks like Java, Python, JavaScript, React, or .NET, depending on the company's tech stack. You'll work alongside experienced developers, participate in code reviews, and contribute to team meetings, gaining exposure to agile development practices and version control systems like Git. This hands-on experience is designed to help you build technical skills, understand industry workflows, and prepare for a full-time developer role.

Job description

Pennoni is seeking an Engineering Intern to join our Leesburg, VA office and support a variety of public and private land development projects throughout the region. This is an excellent opportunity for a civil engineering student to gain hands-on exposure to site layout, grading, utility design, stormwater management, permitting, construction documents, and engineering reports while working closely with experienced engineers and project managers. In this role, you will support project teams through various stages of design, from early planning and conceptual layouts through detailed design and permitting support.
Primary Responsibilities:
  • Assist project engineers with the preparation of civil engineering plans for public and private land development projects.
  • Support site design tasks, including site layout, grading, stormwater management, erosion and sediment control, and utility design.
  • Help prepare permit application materials, exhibits, calculations, and supporting documentation for agency review.
  • Assist with reviewing local municipal ordinances, county requirements, and state regulations applicable to assigned project tasks.
  • Contribute to engineering reports by organizing technical information and documenting project assumptions, design criteria, and regulatory requirements.
  • Work in a collaborative, multi-disciplinary team environment under the guidance of experienced engineers and project managers.
  • Additional tasks may be assigned, as needed.

Required Qualifications:
Enrollment in a Civil Engineering or related engineering program, such as Environmental Engineering or Construction Engineering, at an ABET-accredited institution. Candidates should have completed or be actively pursuing coursework related to site/civil design, land development, water resources, transportation, utilities, or related civil engineering topics.
Preferred Qualifications:
  • Prior internship, co-op, academic project, or work experience related to land development, site/civil design, stormwater management, water resources, utilities, or construction is a plus.
  • Familiarity with AutoCAD Civil 3D, Bluebeam Revu, and related engineering or design tools.
  • Proficiency with basic office software applications, especially Microsoft Office 365 and Adobe PDF applications.
  • Exposure to stormwater management design concepts, erosion and sediment control, grading, utility design, or Hydrology and Hydraulics (H&H) coursework is helpful.
  • Strong organizational skills, attention to detail, and willingness to learn in a fast-paced project environment.
  • Ability to communicate clearly, ask questions, take direction, and work both independently and as part of a team.

Why Pennoni?
Founded more than 50 years ago, Pennoni is a multi-disciplinary consulting engineering firm with a long-standing commitment to delivering practical solutions for public and private clients. In our Leesburg office, interns can gain meaningful hands-on exposure to site layout, grading, utility design, stormwater management, permitting, and construction documentation while supporting land development projects throughout the region. You will work closely with experienced engineers and project managers, learn how civil engineering coursework is applied to real projects, and develop practical skills that can support future internship, graduate engineer, and professional development opportunities.
