Responsibilities
BS Degree in engineering with 4-8 years relevant work experience
Strong command of network design principles and engineering practices, including the implementation and management of core L2/L3, routing protocols, VLAN segmentation, and Quality of Service (QoS) in high-bandwidth Ethernet environments
Hands-on experience architecting and stress-testing high-performance, lossless fabrics. Proven ability to validate and benchmark network behavior, meticulously analyzing throughput, latency, and congestion patterns within complex, multi-rack deployments
Proficient in optimizing Linux systems through kernel tuning and NIC driver configuration. Leverages Python, Bash, and Ansible to automate infrastructure provisioning, configuration management, and validation workflows, enhancing efficiency and repeatability
Acknowledged for exceptional troubleshooting acumen, with a demonstrated ability to diagnose and resolve multifaceted performance, connectivity, and integration challenges by systematically isolating faults across the entire hardware and software stack
M.S. Degree with minimum 3-5 years experience
Proven experience designing, configuring, and validating RoCEv2 (RDMA over Converged Ethernet) fabrics. This must include hands-on work with Priority Flow Control (PFC) and Explicit Congestion Notification (ECN) on data center switches
Deep expertise in configuring and tuning the Linux network stack for high-performance workloads, including direct experience with RDMA drivers (e.g., NVIDIA OFED), kernel bypass methods, and optimizing network performance through CPU affinity and interrupt handling
Demonstrated ability to root-cause performance bottlenecks across the entire stack. This includes using tools to measure and analyze application-level throughput, RDMA-level latency and correlating it with system metrics (CPU, memory) and network-level statistics (packet drops, PFC pause frames)
Experience troubleshooting elusive integration issues that manifest as network problems, but originate in server hardware or firmware. This includes debugging interactions between BIOS/UEFI settings, PCIe lane allocation, NIC firmware and OS driver behavior
Experience using Ansible or Python to configure multi-vendor switch fabrics, deploy custom OS images via PXE and run automated test suites to validate fabric health and performance
