NEW YORK — Shake Shack announced the latest in a series of leadership appointments and promotions, naming Tara Comonte, chief financial officer, to the expanded role of president and c.f.o.

As president, Ms. Comonte will focus on scaling the burger chain’s infrastructure, broadening support and guidance on day-to-day operations, the company said. She will continue overseeing finance, accounting, technology, internal audit and legal.

Ms. Comonte has more than 20 years of strategy, finance, technology and operations experience, primarily with global media and advertising companies. Since joining Shake Shack in 2017, she has helped lead an increased focus and investment in digital technology as well as diversity and inclusion initiatives.

“We are in the midst of exciting growth and I’m thrilled for Tara to play an even larger role in helping lead Shake Shack to its full potential,” said Randy Garutti, chief executive officer of Shake Shack. “She’s had a tremendously positive impact across the company over the last few years, and combined with her proven track record, Tara’s expanded role will now benefit so many other areas of our business while allowing me to focus even more on where we’re headed.”

Ms. Comonte’s new role reflects Shake Shack’s expansion both domestically and internationally, including first-in-market openings in Mainland China and Mexico. The company has focused on strengthening its leadership team, adding a new chief development officer, chief global licensing officer, chief information officer and chief marketing officer earlier this year.
