VPN & WAN Optimization Tester (3-6 yrs)

Key Responsibilities :

- VPN Protocol Testing : Conduct thorough testing of various VPN protocols (OpenVPN, IPSec, IKEv2, WireGuard, etc.) to ensure proper functionality and performance.

- End-to-End Testing : Execute end-to-end testing on VPN software across different platforms (Windows, macOS, Linux, iOS, Android) to ensure compatibility and stability.

- Performance Testing : Assess VPN performance under varying network conditions, focusing on latency, throughput, and connection stability.

- Security Testing : Identify and evaluate potential security vulnerabilities in VPN implementations, including testing for data leakage, DNS leaks, and other security threats.

- WAN Optimization Testing : Test and validate WAN optimization technologies, including deduplication, compression, protocol optimization, and TCP acceleration to ensure optimal application performance over wide-area networks.

- Optimization Evaluation : Evaluate how WAN optimization solutions impact the performance of VPN connections, and work on improving the overall network efficiency in a high-latency or low band width environment.

- Troubleshooting : Reproduce, debug, and isolate defects related to VPN and WAN optimization connectivity and performance, working closely with developers to fix issues.

- Automation : Develop and maintain automated test scripts to ensure consistent testing for VPN and WAN optimization functionality, load, and performance.

Required Qualifications :

- Bachelor's degree in Computer Science.

- 3+ years of experience in software testing, with a focus on VPN and WAN optimization products and networking technologies.

- Strong knowledge of VPN technologies and protocols (IPSec, PPTP, L2TP, OpenVPN, WireGuard, Cisco VPN, Microsoft Always on)

- Solid understanding of WAN optimization technologies (e.g., Riverbed SteelHead, Cisco WAAS, Silver Peak) and their impact on network performance.

- Experience testing networking protocols like TCP/IP, DNS, HTTP/HTTPS, and routing.

- Proficiency with networking tools such as Wireshark, tcpdump, NetFlow, and others for analyzing network traffic.

- Hands-on experience with testing VPN clients, WAN optimization devices, and servers on multiple platforms (Windows, macOS, Linux, iOS, Android).

- Strong knowledge of firewalls, proxies, and NAT traversal as it relates to VPNs and WAN optimization.

- Experience with performance testing tools such as JMeter, LoadRunner, or similar.

- Knowledge of security testing techniques (pen testing, vulnerability assessments) to identify weaknesses in VPN and WAN optimization implementations.

- Familiarity with automation testing tools like Selenium, Python, or similar scripting languages for network-based testing.
