With a recent $18 million equity round in place, e-learning solutions provider Plateau Systems has hired Steven Roth as senior vice president of sales and marketing. In addition, Plateau announced the appointment of Shelly Heiden as vice president of professional services; Paula Scanlon as vice president of marketing; and Hung Vu as vice president of product engineering.

Roth, whose technology experience spans more than two decades, joins the Fairfax, Va.-based Plateau after serving as vice president of Saba software. His initial focus is to expand the company's reach into the global enterprise market, while deepening its stake among regulated industries. He has served in key management roles at Riverbed Technologies, 3Com Corporation, and Octel Communications, and was a member of the original Sun Microsystems sales management team.

Heiden, who managed national and global practice areas at PSINet Consulting Solutions, will direct Plateau's implementation of e-learning solutions while Scanlon will focus on rapidly growing Plateau's image.

Vu, who managed the QA/QC/Tools division at Proxicom, is overseeing the latest upgrade to Plateau's Enterprise Learning Management System, and will continue to expand Plateau's product offerings.
