Circuit Designer

**Voice Circuit Designer (100% Remote 12-month Contract)**

Overview:

Optomi, in partnership with a telecommunications client, is seeking a Voice Circuit Designer to support the migration of SS7, 911, and other TDM circuits from third-party transport onto a modern circuit-switched packet network. The network uses Ribbon equipment for circuit emulation and connects markets through an IPVPN cloud.

The designer will determine end-to-end circuit routing across TDM, transport, and packet network facilities; document the required designs; and submit work requests for implementation in TIRKS.

Key Responsibilities:

• Research circuit routing options in TIRKS and review TDM, transport, and packet network diagrams.
• Determine whether circuits can connect directly from a switch or DACS to Ribbon equipment, or need to travel over TDM transport to a neighboring office.
• Design new T1 facilities where needed at either end of the circuit.
• Specify DS0 assignments across the T1s and other facilities along the end-to-end path.
• Assess whether existing T1, DS3, OC-3, OC-12, or OC-48 carrier facilities can be disconnected after migration.
• Document circuit designs and facility impacts in spreadsheets, then create WMS tickets for the team to enter the designs in TIRKS.
• Coordinate with network and implementation teams to clarify design requirements and support circuit migration.

Required Experience:

• Experience designing voice or transport circuits in a telecommunications network.
• Working knowledge of TIRKS and circuit design workflows.
• Familiarity with SS7, 911, TDM, DS0, T1, DACS, and digital transport facilities.
• Ability to interpret network diagrams and determine end-to-end circuit routes.
• Experience documenting circuit designs and submitting work requests or implementation tickets.
• Strong attention to detail and ability to manage a high volume of circuit design work.
