The role is based in a New Jersey office that operates as a full-service design/build firm with architects, engineers, and construction professionals working together under one roof. The team works in the office five days per week and offers flexible start times, typically between 7:00 a.m. and 9:00 a.m. The environment is casual and collaborative, with a "small firm" mindset and minimal bureaucracy, despite being a well-established firm with a long history in the market. The office supports a wide variety of project types, including public projects such as schools and municipal buildings, as well as private projects such as pharmaceutical labs, industrial facilities, and corporate offices. Project sizes range from small assignments to large, complex designs, and each project is treated as unique rather than standardized or repetitive. Staff benefit from working alongside a tenured team with significant senior talent and strong emphasis on mentorship, professional development, and continuous career growth. The firm operates as a true design/build organization, allowing engineers to see projects from inception through completion and to collaborate closely with in-house disciplines using tools such as AutoCAD, Revit, Trane Trace, and other HVAC modeling software.
