About the role
Key responsibilities & impact- Lead the definition and development of holistic test strategies, test plans, and test cases for complex data center network solutions, including Layer 2/3, SDN, DCN, EVPN/VxLAN, and high-performance fabrics (e.g., RDMA/RoCE).
- Work closely with network architecture and engineering teams to understand design specifications and translate them into effective test methodologies.
- Identify key performance indicators (KPIs) and scalability metrics for network validation.
- Hands-on execution of complex network tests, including functional, performance, scalability, stability, and reliability testing.
- Analyze test results, identify defects, conduct root cause analysis, and work with development teams to resolve issues.
- Perform deep-dive packet analysis and network protocol debugging using tools like Wireshark, tcpdump, and network analyzers.
- Design, develop, and maintain advanced test automation frameworks and scripts (e.g., Python, Ansible, Terraform, Robot Framework) to accelerate testing cycles and improve efficiency.
- Evaluate, recommend, and integrate new testing tools and technologies into our CI/CD pipelines.
- Drive the adoption of best practices in test automation and continuous integration.
- Lead and mentor a small team of networking test engineers, providing technical guidance, code reviews, and fostering a culture of excellence and continuous improvement.
- Act as a technical subject matter expert for network testing within the organization.
- Drive innovation in test methodologies and processes.
- Collaborate cross-functionally with network architecture, development, operations, and product teams to ensure comprehensive test coverage and high-quality deliverables.
- Clearly communicate test progress, risks, and results to stakeholders at all levels.
- Contribute to documentation, runbooks, and operational guides.
Requirements
What you’ll need- Bachelor's or Master's degree in Computer Science, Electrical Engineering, Network Engineering, or a related technical field.
- 8+ years of experience in network engineering, network operations, or network testing roles, with at least 3 years focused specifically on data center networking.
- 3+ years of experience in a lead or senior technical role, mentoring junior engineers or leading test initiatives.
- Expert-level understanding and hands-on experience with Layer 2 and Layer 3 networking protocols in large-scale data center environments (e.g., BGP, OSPF, ISIS, MPLS).
- Extensive experience with modern data center interconnect technologies (EVPN/VxLAN).
- Strong knowledge of high-performance networking, including RDMA over Converged Ethernet (RoCE) and associated congestion control mechanisms (PFC, ECN, DCQCN).
- Familiarity with network operating systems like SONiC (preferred), Cisco NX-OS, Arista EOS, and Juniper Junos.
- Proficiency in at least one scripting language (e.g., Python, Go) for test automation, API integration, and data processing.
- Experience with network automation tools (e.g., Ansible, Terraform, Netmiko, NAPALM).
- Experience building and maintaining test frameworks (e.g., Robot Framework, Pytest).
- Proven experience designing and executing various types of network tests: functional, performance (throughput, latency, jitter), scalability, reliability, and security.
- Expertise with network testing tools (e.g., IXIA, Spirent, Keysight, TRex, Ostinato, SmartBits).
- Strong packet analysis and troubleshooting skills using Wireshark, tcpdump, or similar tools.
- Strong proficiency in Linux/Unix operating systems.
- Understanding of virtualization (VMware, KVM) and containerization technologies (Docker, Kubernetes).
