Why work for us

Empirix Inc. is a privately held company which designs and manufactures service assurance testing and monitoring equipment for IP-based communications networks such as Voice-over-Internet-Protocol (VoIP), IP Multimedia Subsystem (IMS)-based, next generation network and 4G wireless networks. Empirix offers enterprise and carrier grade products as well as quality assurance products for network equipment manufacturers. Empirix is headquartered in Billerica, MA. Empirix’s Hammer test technology was originally developed at Hammer Technologies, Inc. Hammer Technologies was founded by Steve Gladstone and John Kuenzig in late 1991. Hammer was originally called Transaction Environments, Inc., but changed its name to Hammer Technologies based on the success of their initial "Hammer" test products. The company started by developing test systems for enhanced telecom services (such as voice mail and IVR), but later moved into VoIP, then a new communication technology. The methodologies developed proved viable for testing, and subsequently monitoring, other IP communications applications such as data, video, web and mobile services. Hammer Technologies was purchased by Teradyne in 1995 as part of Teradynes effort to diversify into more software-oriented test systems. On September 6, 2000, the Hammer test technology was spun out of Teradyne and became Empirix Inc. Alex d’Arbeloff, co-founder of Teradyne, was appointed Chairman of the Board.
