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
