Job Description & Details
If you know your way around legacy TDM networks and have spent time wrestling with SS7 and 911 circuits, this 12-month contract with a major telecom player is right in your wheelhouse. You'll be working behind the scenes to map out complex routing paths, keeping critical infrastructure connected while the business modernizes. It's a heavy-duty documentation and inventory tracking gig that requires deep telecom fundamentals.
What You'll Actually Be Doing
Expect to spend a good chunk of your day digging through internal circuit inventory systems like TIRKS and studying dense network diagrams. You'll figure out how to bridge third-party transport straight into the core network, mapping out DS0s onto new and existing T1s across multiple switches. When you aren't designing new paths, you'll be auditing older carrier circuits to see what can be safely decommissioned and spinning up internal work-management tickets to keep the deployment moving.
The Core Tech Stack
You need absolute fluency in traditional telecom infrastructure, specifically TDM circuits, SS7, 911 routing, and transport technologies ranging from T1s up to high-capacity OC-level circuits. Systems proficiency with TIRKS and the ability to interpret intricate network diagrams are non-negotiable here because your entire day revolves around tracing paths and documenting precise signal flows.
Interview Expectations
Expect the hiring team to test your deep understanding of circuit routing by presenting you with a hypothetical failure scenario involving an SS7 or 911 circuit and asking how you'd reroute it using available T1 or transport assets. They want to see how methodically you check inventory systems and evaluate switch constraints under pressure. They'll also likely probe your familiarity with TIRKS and carrier transport hierarchies to ensure you can hit the ground running without hand-holding.
Application Advice
Skip the generic IT buzzwords and tailor your resume to scream telecom infrastructure. Make sure terms like SS7, 911, TDM, TIRKS, circuit design, and transport hierarchies are front and center so the ATS flags you immediately. Give concrete examples of past projects where you managed complex circuit inventories, designed multi-hop T1 paths, and successfully cut over or decommissioned legacy carrier links.
