Parallel Wireless is seeking an experienced and hands-on Technical Lead QA Engineer with a deep understanding of telecommunication or networking systems (4G/5G or Routing/Switching) and strong expertise in Linux-based debugging and system integration.
The ideal candidate will lead QA efforts for complex multi-component environments, ensuring stability, reliability, and fast recovery in CI and Nightly setups.
This position focuses on practical problem solving, system-level analysis, and cross-team collaboration to ensure smooth operation and high quality of network software releases.
What you'll do:
Lead QA activities for complex CI/Nightly environments, including multi-node network or 4G/5G setups.
Perform deep debugging and failure analysis across distributed Linux-based systems — including log correlation, packet tracing, process monitoring, and system resource analysis.
Design, build, and maintain end-to-end lab setups integrating various network elements (Core, RAN, routers, switches, simulators, and management systems).
Investigate and resolve integration and stability issues between system components and software releases.
Collaborate with Dev, DevOps, and Automation teams to ensure the health and reliability of CI pipelines and test environments.
Analyze and correlate logs from multiple systems (e.g., Jenkins, Kubernetes, syslog, SNMP, or network captures).
Contribute to test planning and validation activities for new network or feature deployments.
Maintain high operational uptime of CI/Nightly test environments by identifying and mitigating recurring issues.
Provide mentorship and guidance to QA engineers on debugging techniques, Linux diagnostics, and test environment maintenance.
Optional: assist with minor scripting (Python/Bash) for log analysis, setup verification, or test monitoring.
What you should have:
6+ years of QA, Integration, or System Validation experience in telecom or networking (Routing/Switching) domains.
Expert-level Linux skills - system services, networking, log analysis, performance monitoring, and shell scripting.
Proven ability to debug and stabilize complex, multi-component network systems.
Hands-on experience with CI/CD tools (e.g., Jenkins, GitLab CI) - understanding logs, pipelines, and test orchestration.
Strong understanding of networking protocols (IP, VLANs, BGP, OSPF, MPLS, GTP, S1, X2, NG, etc.) or 3GPP architectures (EPC, 5GC).
Experience working with network or UE simulators, routers, or switches in lab environments.
Familiarity with containerized environments (Docker, Kubernetes) and cloud-based test systems.
Excellent analytical, troubleshooting, and communication skills.
Scripting ability in Bash or Python for diagnostics, environment setup, or automation support.
Education:
Bachelor’s degree in Computer Science, Telecommunications, or a related field (or equivalent hands-on experience).
