Overview: Dive into the world of telecom protocols, network traffic, and real-time systems. This role focuses on building realistic traffic simulations, testing contact centre systems, and applying automation to network assurance. What You’ll Do: Simulate telecom traffic (SIP, RTP, VoIP) and analyse system behaviour Use tools like SIPp, Wireshark, or Scapy to create and test call flows Create IVR and contact centre load test cases with 5K–10K call capacity Analyse packet flows using Wireshark, tcpdump, and protocol traces (SIP, RTP, HTTP, Diameter) Collaborate on telecom AI assurance and anomaly detection initiatives Develop telecom network lab environments (RAN, Core, OSS, BSS) using open-source tools Explore testing frameworks and open-source automation libraries Contribute to chaos engineering concepts and performance testing What We’re Looking For: Solid understanding of network fundamentals and protocols (SIP, RTP, IMS, VoLTE) Hands-on experience with Linux CLI, scripting (Bash/Python), and packet analysis tools Curiosity about telecom systems, packet behaviour, and system observability Strong documentation habits and attention to detail Bonus Points: Experience with SIPp, Scapy, or IVR testing frameworks Familiarity with Kamailio, OpenSIPS, FreeSWITCH, Asterisk, or PJSIP Exposure to tools like OpenAirInterface, srsRAN, O-RAN SC, Open5GS, Free5GC, UERANSIM, Magma, ONAP Interest in 5G, virtualisation, or telco cloud Familiarity with Jenkins, Python-based automation, or Robot Framework Show more Show less
