Job Description

We have an immediate opening for an SDN NETCONF Developer/Radio Network Designer-Tester to work full-time onsite in Middletown, NJ.   You will be part of a group that is responsible for certifying new radio equipment and systems for integration into service provider carrier grade cellular backhaul networks.  Work includes:

  • SDN Layer 2 Ethernet testing
  • Network Virtualization; deploying virtual machines and networking
  • SDN NETCONF Development
  • Layer 2 & 3 Ethernet switch routing provisioning and testing
  • Millimeter wave microwave radio network design and test
  • Developing and conducting test plans
  • conducting bench and field experiments to characterize radio performance
  • collecting, processing, and analyzing data
  • documenting results – developing Network Design Requirements; Configuration Requirements, Deployment Guides, and Product Change Notices
  • determining the impact of results as they relate to future technology investigation
  • supporting physical simulations of this technology in the field
  • performing experiments using multiple radio profiles and frequency bands as new radio software/hardware is acquired and as the research direction dictates
  • responsible for Tier-4 field support once equipment is deployed, which may require immediate hands-on re-configuration of hardware

Travel will be rare, but may be required to support field trials around the United States when equipment is first deployed after completing lab testing.  The ideal candidate is someone who likes to work on leading-edge technologies, likes to learn new techniques and capabilities, and keeps current in radio and interconnecting optical technologies, and someone who is also willing to accept short-term, expert assignments as requested by the team.

Required Skills

  • SDN NETCONF development experience
  • Solid experience with VMWare KVM
  • Experience with layer 2/3 Ethernet switch routing provisioning and testing
  • Experience with millimeter wave microwave radio technologies
  • Direct hands-on experience with RF testing and debugging along with radio network design
  • A broad background in radio engineering and Ethernet performance characterization is required (with knowledge of governing deployment issues such as RLAG and adaptive modulation correlated with throughput)
  • Background in NLOS, and Point to Multi-Pont and RDAS is highly desirable
  • Must be familiar with measurement techniques and test equipment, data acquisition interfaces, and issues relevant to connectivity to carrier grade cell site backhaul networks
  • Must have hands-on experience with the Spirent Test Center, knowledge of basic routing protocols (like OSPF, RSTP, BDF), and knowledge of PDH technology and associated test gear
  • Should have proficiency in design, provisioning, and maintenance of networks
  • Must have specific knowledge of Layer 2 Ethernet performance testing RFC 2544
  • Must have excellent writing skills in English


Co-residency with the hardware is required to change ports/cards/cables, confirm configurations when test results are negative, and to generate specific alarm conditions when testing Element Management Systems.  Exposure to multiple vendor relationships and intellectual property requires individuals to have a high standard of integrity and a strong sense of professional ethics. Individuals must have the flexibility to participate in and make progress on multiple projects at the same time as ad-hoc requests for test results are occasionally made by other organizations within AT&T.

Desired Skills

Candidates should be able to interact well with other team members and equipment vendors.  Hands-on experience with radio link management tools and radio provisioning is desirable. Strong knowledge of configuring and building L2/L3 networks is a plus.
