New York, NY—Hatfield Group, the New York-based structural engineering firm founded by Erleen Hatfield, has hired Rebecca Jones, SE, PE, LEED AP BD+C as Principal and Cori Kwitkin, PE, LEED Green Associate as Associate Principal. Jones and Kwitkin will oversee and manage the design and delivery of innovative structural solutions for Hatfield Group’s institutional, mixed-use, stadium, and multi-family residential projects across the United States and worldwide.

“As two of engineering’s leading professionals, Rebecca and Cori will advance our mission to deliver design-driven structural solutions for some of the world’s most complex buildings,” says Erleen Hatfield, Managing Principal of Hatfield Group. “More, as two of the most widely recognized women in the AEC industry, Rebecca and Cori further our vision as an engineering firm founded by women, led by women, and committed to cultivating the talent women bring to the field.”

“Hatfield Group is among those leading the charge to break our profession’s glass ceiling and showing women in engineering that they can be industry leaders,” says Jones. “It is essential for young women to see firms like Hatfield Group, where we are celebrated and can advance our careers.”

Jones and Kwitkin have led some of the most high-profile design and engineering projects around the world. Jones previously served as Senior Associate at Thornton Tomasetti, where she oversaw projects including the 1.8-million-square-foot tower 10 Hudson Yards and Al Faisaliah, a 100-meter tall hotel and commercial building in Riyadh, Saudi Arabia. Kwitkin served as Associate Principal at Thornton Tomasetti, where she led award-winning projects, including the Physical Sciences Building at Cornell University and Seoul International Finance Center, a 5.4-million-square-foot mixed-use development.

Throughout their careers, Jones and Kwitkin have supported and mentored . In 2014, Jones co founded The Knitting Club with Diana Zakem (now Director of Construction at Brookfield Properties), a professional networking and mentorship group for women in New York City’s architecture, engineering, construction, and real estate industries.

At Thornton Tomasetti, Jones created the National Women Advancement Committee of Women@Thornton Tomasetti (W@TT), a program that fosters the professional success, advancement, and visibility of women engineers. The committee established $8,000 in grants for women in engineering and co-developed the Mastermind Pilot program, a company-wide training initiative for women associates. Jones also started and chaired the W@TT Local Chapter in Seattle and has participated in AIANY’s Women in Architecture Committee and AIA Seattle’s Diversity Roundtable.

Kwitkin volunteered as a mentor for Women@TT during her time at the firm, working closely with an up-and-coming engineer to support her professional development.

“Becoming a mentor has been extraordinarily rewarding,” says Kwitkin. “By fostering a supportive environment, the process allowed my mentee and I to openly discuss navigating the challenges of being a woman in a traditionally male-dominated industry—everything from advancing in our field to balancing work- and home-life.”
