Segal began his editorial career as a journalist at In Pittsburgh Weekly and WQED's Pittsburgh Magazine. In 2006, he joined the staff of the long-running fantasy magazine Weird Tales, and was named its editorial and creative director in early 2007 as part of an overall revamp of the publication. The April/May 2007 edition (issue #344) featured the magazine's first all-new design in almost 75 years; subsequently, under Segal's direction, Weird Tales published works by a wide range of strange-fiction authors including Michael Moorcock, Caitlín R. Kiernan, Cherie Priest, Norman Spinrad, Jay Lake, and Carrie Vaughn, as well as artwork by a younger generation of artists such as Molly Crabapple, Steven Archer, and Jason Levesque.

In 2009, Segal and fiction editor Ann VanderMeer won^[1] a Hugo Award for Weird Tales, the first and only time in its 75-year history. Segal and VanderMeer were also nominated^[2] for a 2009 World Fantasy Award for their work at the magazine, and were nominated again for Hugo Awards in 2010 and 2011. In 2010 Segal left the post of editorial and creative director to pursue book editing full-time; he remained Weird Tales' senior contributing editor, while VanderMeer was elevated to editor-in-chief.^[3]

As a freelance book editor and designer, Segal served as chief book-cover designer for the World Fantasy Award-winning publisher Prime Books and the urban fantasy line Juno Books. He also contributes to the Interstitial Arts Foundation,^[4] where he was a board member from 2005 to 2010.

In 2012, Segal was named editor in chief of the Philadelphia Weekly.
