• Performance Debugging: Perform deep-dive analysis into performance bottlenecks at the kernel and hardware-abstraction layers including control plane.
• Design and evolve scalable test frameworks, test automation, and validation pipelines for both software and hardware.
• Collaborate with engineering leaders, product management, hardware, and TAC teams to define quality goals, test scope, and execution plan.
• Contribute to customer demos and technical presentations to showcase product and solution capabilities.
• Represent the test organization in multi-functional forums to influence release decisions, risk assessment, and quality metrics.
• Modern Test Practices: Apply modern Test workflows, including AI-assisted coding tools (such as GitHub Copilot, Claude, or Codex) and integrated development environments like VSCode, to accelerate the development lifecycle and improve code quality.

Minimum Qualifications and Requirements:

• Bachelor’s degree in electrical engineering, Computer Science, or an equivalent technical field (BE/ME/CS/AI/ML).
• 8-12 years of proven industry experience in testing Layer 1, Layer 2, and Layer 3 networking products, platform validation, and product development.
• Solid understanding of the Software Development Life Cycle (SDLC), with expertise in requirements analysis, test plan creation, execution, and release validation.
• Extensive experience in platform testing, PHY/MAC layer validation, and high-speed interface integrity testing, which you will use to validate our Next-Gen engineering platforms.
• Demonstrated ability to architect robust test plans and map them to critical platform testing areas, including port validation, Datapath/control path validation, FPGA, ROMMON, and environmental/hardware functional testing (e.g., power supplies, LEDs, fans).
• Deep technical knowledge and hands-on experience conducting deep-dive testing of MACsec, Port-Channels, Flow Control, and Quality of Service (QoS).
• 6+ years of experience and strong proficiency in driving test automation development using Python and REST APIs to execute longevity, soak, and stress testing.
• Expert-level troubleshooting and root cause analysis skills, applying advanced debugging techniques, kernel logs, and system traces.
• Solid foundation in Linux operating systems and hands-on experience with virtualization technologies, such as KVM and ESXI.
• Hands-on expertise with industry-standard network traffic generators (Ixia, Spirent) and protocol analyzers (Wireshark).
• Proficiency in utilizing Git for source code and version control management.
• Exceptional analytical, problem-solving, and communication skills, with a demonstrated ability to collaborate effectively across multi-functional teams.
• Proven track record of mentoring junior engineers, fostering teamwork, and a strong passion for talent development.

Preferred Qualifications:

• Industry-recognized certifications such as CCNP Enterprise Infrastructure or equivalent.
• Solid understanding of optical networking, various cabling technologies, and advanced routing concepts.
• Prior experience conducting Interoperability, Performance, Scale, and Convergence testing, as well as reproducing and resolving complex customer issues.
• Practical experience working within Agile development methodologies and fast-paced engineering environments.
