We are not your typical engineering firm. We’re a team that provides a diverse range of engineering solutions on a person-to-person level. At approximately 100 employees, our size allows us to have expertise in many disciplines, but our team also knows each other. It’s an increasingly rare trait, and something we’re proud of. Duffield provides many regular opportunities for staff to truly get acquainted outside our walls through projects that make it easier for them to communicate and collaborate across disciplines for the benefit of our clients. We find that actively staying in touch with the community, specifically through events and outreach, helps our employees to further develop these relationships and reminds us all why we entered this technical career in the first place: to make a difference in the world around us. 

Because of our unique culture and environment, Duffield has been recognized as a Top Work Place in Delaware in 2018!
