Description
As a Sr Network Test Engineer , Data Center Fabrics, you will design, build, and execute test plans for functional/feature validation, customer use cases, and proof-of-concept engagements on data center switching platforms.
You will work primarily from an HPE office and collaborate with development teams to reproduce issues and verify fixes.
Key responsibilities:
- Design, develop, and execute comprehensive test plans to validate Junos/Sonic functionality on Broadcom-based switching platforms.
- Replicate customer network architectures in the lab, including multi-stage IP Clos fabrics.
- Perform functional, interoperability, scale, and convergence testing of BGP-based underlays and EVPN-VXLAN overlays.
- Test AI/ML data center fabric use cases, including RoCEv2 traffic profiles and lossless Ethernet behavior.
- Validate IPv4 and IPv6 unicast/multicast forwarding, dual-stack designs, and IPv6-only fabric use cases.
- Configure and troubleshoot routing and overlay protocols.
- Use traffic generators to build traffic profiles, measure throughput, latency, packet loss, and convergence times.
- Identify, isolate, and document software defects.
- Author clear, detailed test plans, test reports, and PoC summary documents.
- Automate repetitive test workflows using Python, pytest, Ansible, or similar frameworks.
- Present test findings and demonstrations to customers during PoC reviews and technical deep-dives.
Requirements:
- Bachelor’s or Master’s degree in Electronics, Computer Science, or a related field.
- 7-10 years of experience in network software/testing/engineering/TAC/escalation role.
- Strong understanding of IPCLOS fabric architecture, AI/ML fabric, BGP, EVPN-VXLAN, and IPv6 networking protocols.
- Strong hands-on CLI experience with at least one major data center NOS.
- Strong hands-on traffic generation and analysis tools.
- Strong troubleshooting methodology.
- Strong analytical, debugging, and documentation skills.
Preferred qualifications:
- Experience running customer PoC labs or certification/qualification/functional testing.
- Hands-on experience with AI fabric benchmarking and validation tools.
- Familiarity with emerging standards such as Ultra Ethernet.
- Familiarity with 100G/400G/800G optics.
- Scripting and automation experience.
- Exposure to telemetry and monitoring.
