- Configure routers, managed switches, VLANs, inter-VLAN routing, NAT, DNS, DHCP, firewalls, VPNs, WAN/MPLS concepts, and relevant 4G/5G or CGNAT scenarios.

- Create network simulation and automation scripts for latency, jitter, packet loss, bandwidth constraints, disconnections, NAT behavior, and recovery scenarios.

- Develop network-focused V&V; plans, test cases, execution evidence, reports, regression coverage, and defect records.

- Validate performance, reliability, resilience, connectivity, audio/video streaming, signaling, remote access, and screen-sharing behavior.

- Use packet captures, application logs, metrics, and structured troubleshooting to isolate root causes.

- Coordinate with infrastructure, cybersecurity, engineering, product, verification, and customer-facing teams.

Required Qualifications and Skills

- Bachelor's or Master's degree in Computer Science, Electronics, Telecommunications, IT, or a related field.

- 7-10 years of relevant network engineering, system validation, test engineering, or infrastructure engineering experience.

- Solid knowledge of TCP/IP, routing and switching, VLANs, NAT, DNS, DHCP, firewalls, VPNs, MPLS/WAN, and network performance analysis.





- Hands-on experience with Cisco, MikroTik, Fortinet, pfSense, Juniper, or equivalent platforms, together with managed switches, routers, and firewalls.

- Experience with Wireshark, packet capture analysis, Linux, connectivity troubleshooting, latency, packet loss, jitter, and log analysis.

- Ability to automate tests or simulations using Python, Bash, or PowerShell.

- Experience establishing and managing physical labs and test environments.

- Ability to work in person from the Bengaluru office.

Preferred Qualifications

- WebRTC knowledge, including ICE, STUN, TURN, and audio/video streaming concepts.

- Experience with LiveKit, Microsoft Teams, Zoom, or similar real-time communication platforms.

- AWS infrastructure, cybersecurity, enterprise network architecture, healthcare or medical-device experience.

- Experience supporting customer deployments and field investigations.

Recruiter Screening Priorities

- Validate that the candidate is a network engineer first and has a practical verification mindset.

- Confirm hands-on configuration experience with firewalls, VLANs, VPNs, routers, switches, and network simulators.

- Ask for examples of customer-environment reproduction, packet-level diagnosis, automation scripts, and lab ownership.
