Billing Manager
About The Position
Security Industry Specialists, Inc. (SIS) provides security solutions to recognized companies and brands, emphasizing innovation, process improvement, and attracting and retaining strong talent.

The position is based 100% on-site in Culver City, California, and requires occasional travel to other SIS offices.
