About Position

We are hiring for Network QA engineer, will lead functional and system testing for carrier-grade networking products and platforms. The role spans L2/L3 protocol validation, MPLS & Traffic Engineering scenarios, NMS functional testing, and SDN controller feature validation?ensuring stable, standards-compliant releases at scale.

• Role: Network QA
• Location: All Persistent Location
• Experience: 5+ years
• Job Type: Full Time Employment
  
  

What You'll Do

• Design, execute, and maintain functional test plans, test cases, and regression suites for L2/L3 protocols and MPLS features.
• Validate Traffic Engineering scenarios (e.g., RSVP-TE/segment routing use-cases, path constraints, protection/restoration).
• Perform NMS/EMS functional testing (fault, performance, configuration, inventory) and validate northbound/southbound integrations (e.g., SNMP/NETCONF/REST).
• Validate SDN Controller workflows: topology discovery, intent/policy, service provisioning, path computation, and rollback behavior.
• Build and execute test topologies (multi-vendor if applicable) using routers/switches/virtual network elements; generate and analyze traffic.
• Log defects with clear repro steps, traces, and packet captures; drive issue isolation and verification of fixes.
• Create test reports, coverage metrics, and sign-off criteria; contribute to release readiness decisions.
• Automate repetitive scenarios where feasible (Python + tools/APIs of NMS/SDN/traffic generators).
• Collaborate with development, architecture, and product teams to refine requirements and acceptance criteria.
  
  

Expertise You'll Bring

• Strong hands-on experience in functional testing of networking products, with a focus on L2/L3 protocol validation including VLAN, STP, ARP, OSPF, BGP, and routing behaviors.
• Solid knowledge of MPLS technologies such as LDP, RSVP?TE, L2/L3 VPNs, label operations, and protection mechanisms.
• Experience in testing Traffic Engineering scenarios including path computation, constraints, reroute, protection, and failure handling.
• Practical exposure to NMS/EMS platforms, including fault, configuration, performance, and topology validation.
• Understanding of SDN controller testing?device onboarding, topology sync, intent workflow, service provisioning, and REST/NetConf/GNMI interactions.
• Proficiency with packet-level debugging using tools like Wireshark/tcpdump and analyzing PCAP traces.
• Experience using traffic generators (Ixia/Spirent/TRex) for performance and feature validation.
• Ability to design robust test plans, test cases, and regression suites, covering positive, negative, and boundary scenarios.
• Familiarity with automation basics using Python/API testing (optional but preferred).
• Strong analytical, problem-solving, and defect-triaging skills with clear documentation and reproducible findings.
• Effective collaboration and communication skills to work closely with development, QA, and product teams.
  
  

Benefits

• Competitive salary and benefits package
• Culture focused on talent development with quarterly growth opportunities and company-sponsored higher education and certifications
• Opportunity to work with cutting-edge technologies
• Employee engagement initiatives such as project parties, flexible work hours, and Long Service awards
