Step into an active core network effort, backfilling a teammate on leave.
Test and troubleshoot core network elements and services from design through deployment.
Define feature requirements directly with the core network vendor.
Support integration between the vendor-delivered core and the company’s own RAN (gNodeB/eNodeB).
What you’ll need
Hands-on experience with 4G/5G core networks and 3GPP standards.
Comfortable testing, troubleshooting and defining feature requirements with vendors.
Working knowledge of RAN integration (gNodeB/eNodeB) — not the primary focus.
High-level networking expertise; no deep certifications required.
Able to start immediately and work Eastern or Central time zone hours.
US-based and eligible to work on ITAR-controlled programs
Nice to have
Background at a major telecom operator or vendor (Nokia, Ericsson, Mavenir).
Prior contract or independent consulting work — you land and add value fast.
