The Network and Security Compliance Test Engineer will be responsible for validating the network functionality, performance, and security posture of our AI data center infrastructure. This role requires a strong understanding of networking fundamentals, routing protocols, hands‑on experience with traffic generation, and a keen eye for security vulnerabilities. You will be instrumental in ensuring our network adheres to compliance standards and provides a reliable, secure foundation for our demanding AI workloads.

As a Network and Security Compliance Test Engineer, you will be a key contributor to the design, implementation, and validation of our AI data center's network and security posture. You'll leverage your deep expertise in networking, routing protocols, and test automation to identify vulnerabilities, optimize performance, and ensure our systems meet the highest standards of security and compliance. This role requires a hands‑on approach, strong analytical skills, and the ability to drive complex testing initiatives.

• Lead the development and execution of comprehensive test plans and strategies for complex network topologies and devices within our AI data center.
• Drive the design of advanced test cases for L2/L3 functionalities, focusing on performance, scalability, and resilience under high-demand AI workloads.
• Oversee and conduct in-depth testing of routing protocols (e.g., BGP, OSPF, ISIS) to validate network convergence, stability, and optimal traffic flow.
• Analyze and interpret complex test data to identify network bottlenecks, performance degradation, and areas for optimization.
• Architect and implement robust security test methodologies to rigorously validate network security controls and configurations.
• Perform advanced vulnerability assessments, penetration testing, and security audits on network infrastructure to proactively identify and mitigate risks.
• Develop and integrate automated security compliance checks into continuous integration and deployment pipelines.
• Design, develop, and maintain sophisticated test automation frameworks and scripts primarily using Python, significantly enhancing test efficiency, coverage, and repeatability.
• Champion the adoption of automation best practices across the team.
• Develop custom tools and utilities to simulate complex network conditions and analyze performance.
• Provide expert‑level troubleshooting and root cause analysis for complex network and security incidents, collaborating effectively with cross‑functional engineering and operations teams.
• Actively participate in network architecture reviews, offering critical insights to ensure testability, reliability, and security are built into designs from inception.
• Mentor and guide junior test engineers, fostering their technical growth and promoting a culture of quality and innovation.

• Bachelor's degree in Computer Science, Electrical Engineering, or a related technical field.
• 3+ years of progressive experience in network testing, with a significant focus on enterprise or hyperscale data center environments.
• Deep knowledge of network architecture and advanced networking concepts (e.g., VXLAN, EVPN, MPLS).
• Experience with various routing protocols, including advanced configurations and troubleshooting of BGP, OSPF, EIGRP, or ISIS.
• Hands‑on experience with commercial traffic generators (e.g., IXIA, Spirent) and/or advanced open‑source tools (e.g., TRex, Ostinato, DPDK‑based solutions).
• Strong proficiency in Python for automation, including developing complex test scripts, frameworks, and API integrations.

• CCNA certification is required; CCIE is highly preferred.
• Direct, hands‑on experience with SONiC OS in a production or large‑scale test environment.
• Working experience or strong familiarity with OCP (Open Compute Project) networking principles and hardware designs.
• Experience with software‑defined networking (SDN) and…
