Network Software Engineer

Teradata is a leading company in cloud analytics and data platforms for AI. They are seeking a Staff Software Engineer to lead the design, development, and evolution of networking software for their massively parallel processing platform, influencing technical direction and mentoring engineers.

Responsibilities:

• Architect, design, and evolve scalable, reliable, and fault-tolerant networking software for high-speed, low-latency interconnects, delivering predictable performance across large-scale MPP systems
• Evaluate and drive adoption of emerging technologies across operating systems, high-performance networking, adapters, DPUs, accelerators, and interconnect fabrics
• Lead complex debugging and root-cause analysis of system-level customer and field issues, including SLES OS crash dump analysis, spanning hardware, firmware, OS, and networking layers
• Define and execute targeted research initiatives and proof-of-concepts to validate new technologies, quantify performance, and guide platform decisions
• Partner with product, hardware, and systems engineering teams to scope, prototype, benchmark, and productionize platform enhancements
• Establish performance benchmarks, validation methodologies, and success metrics for networking and interconnect innovations
• Influence platform roadmaps through deep understanding of industry trends, academic research, and partner technologies
• Mentor and technically guide other engineers through design reviews, code reviews, and architectural discussions
• Leverage AI-assisted coding, analysis, and testing tools to accelerate development cycles and improve code quality and reliability

Requirements:

• Strong background in HPC or large-scale distributed systems development
• Proven experience with Linux kernel and driver development in C, including production support
• Deep familiarity with bare-metal and virtualized environments, including performance tradeoffs
• Expertise in InfiniBand and Ethernet networking, leveraging RDMA and RoCE for low-latency, high-throughput communication
• Solid understanding of TCP/IP and UDP networking, along with Linux networking, tuning, and diagnostic tools
• Packet-level analysis and Linux kernel debugging using tools such as tcpdump, kgdb, and crash
• Experience designing and optimizing high-throughput, low-latency data transport protocols
• Strong knowledge of the Linux kernel, including DKMS, driver lifecycle management, and compatibility across kernel versions
• Proficiency in C, Bash, and Python for systems programming, automation, and diagnostics
• Experience with massively parallel processing (MPP) using message-passing interfaces
• Effective use of modern AI-assisted development tools to accelerate design, coding, and debugging
• Bachelor's degree in Computer Science (distributed systems focus preferred), Computer Engineering, or Electrical Engineering, or equivalent practical experience
• 7+ years of experience in high-performance Linux systems or networking software development, with demonstrated technical leadership
• Experience with DPUs, SmartNICs, or hardware offload technologies
• Hands-on work with kernel-bypass networking (e.g., RDMA verbs, DPDK, XDP, eBPF)
• Experience with high-speed Ethernet (100G/200G/400G/800G) and modern interconnect fabrics
• Experience tuning systems for NUMA, CPU affinity, cache locality, and memory bandwidth
• Exposure to distributed storage or database platforms in production environments
• Experience working with hardware vendors (NICs, switches, accelerators) on performance or integration issues
• Contributions to open-source networking, kernel, or systems software projects
