Senior Network and Security Compliance Test Engineer
Celestica, San Jose, California, United States, 95199
Overview
Senior Network and Security Compliance Test Engineer. The role focuses on validating the network functionality, performance, and security posture of our AI data center infrastructure. This requires a strong understanding of networking fundamentals, routing protocols, hands-on traffic generation, and a keen eye for security vulnerabilities. You will help ensure the network adheres to compliance standards and provides a reliable, secure foundation for demanding AI workloads. Req ID: 125022 Remote Position: No Region: Americas Country: USA State/Province: California City: San Jose Responsibilities
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. Ensure strict adherence to internal security policies and external regulatory compliance standards (e.g., NIST, ISO 27001, GDPR) relevant to data center networking. 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 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. Required Qualifications
Bachelor's degree in Computer Science, Electrical Engineering, or a related technical field. 7+ 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). Extensive experience with various routing protocols, including advanced configurations and troubleshooting of BGP, OSPF, EIGRP, or ISIS. Expert-level 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. CCNP certification is required; CCIE is highly preferred. Preferred Qualifications
Direct, hands-on experience with SONiC OS in a production or large-scale test environment. Working experience or strong familiarity with Open Compute Project (OCP) networking principles and hardware designs. Experience with software-defined networking (SDN) and network function virtualization (NFV) concepts and testing. Proven experience with network security tools and methodologies (e.g., firewalls, IDS/IPS, access control, encryption). Familiarity with cloud networking concepts (AWS, Azure, GCP). Experience with Linux system administration and container orchestration (Docker, Kubernetes). Compensation
Salary Range: $109,000 – $162,000 annually. Note: the posted range is an estimate and may change based on duties, credentials, experience, or geographic jurisdiction. Notes
