As our Systems Performance engineer, you will be a member of a centralized team and primarily responsible for ensuring superior, end-to-end reliable wireless voice and data services in a large service provider network. These services include current 4G LTE, VoLTE, VoWifi, and TRFO/NNI services as well as future 5G services, SDN/NFV, MEC, and other cloud-native services. Additional responsibilities will include working with various teams on new service integrations/upgrades, defining standard best practices, implementing automation, providing in-depth troubleshooting, supporting field teams, and providing reporting to executive management to help drive business decisions.
This position requires a working knowledge of IP networks and applicants are expected to have demonstrated experience working with or detailed study of network protocols such as TCP/IP, IPv6, MPLS, BGP, DNS, DIAMETER, RTP, and SIP. This engineer will also need an understanding of 3GPP LTE standard EPC network elements including the MME, SGW, PGW, and ePDG as well as interfaces such as S1-U, S1-MME, S10, S11, S5, S2a, S2b, S6a, S6b, Gx, Gy, Rf, and SGi. Additionally, this position will focus on performance of a voice over LTE IMS service and need to be familiar with SIP call flows and elements such as CSCF, SBC, SR, MRFP, HSS, ENUM, TAS, and SCG.
There also is a high emphasis on using various software tools such as network performance managers (SevOne), network protocol analyzers (Netscout, Irisview, Wireshark), data analytic/visualization software (Tableau, R, Hive/Hadoop), and programming languages to proactively identify, automate, investigate, and resolve anomalies with various key performance indicators (KPIs), log messages, call flows, and raw packets.
