Zusammenfassung

Clockwork.io is seeking a Senior Systems Engineer – RDMA Networking & Storage to help build and optimize high-performance infrastructure for AI and HPC systems. You’ll work across RDMA networking and storage data paths, spanning compute hosts, NICs, DPUs, smart switches, storage systems, and the Linux software stack.

This role focuses on RoCE networking, NVMe-oF, congestion control, and latency/throughput optimization, with ownership from design through deployment.

Qualifikationen

• 5+ years of experience in systems, networking, storage, HPC, or other performance-critical software development.
• Strong proficiency in low-level C/C++.
• Strong understanding of RDMA networking, including RoCE and RDMA Verbs.
• Strong understanding of networking fundamentals, including packet processing, queues, congestion, and flow control.
• Experience debugging low-level Linux networking, storage, or driver behavior.

Aufgaben

• Design, build, and optimize high-performance RDMA networking and storage systems.
• Work with RoCE, RDMA Verbs, and NVMe-over-Fabrics.
• Develop systems that leverage DPUs, SmartNICs, and programmable switches for packet processing, telemetry, control, and data-path acceleration.
• Develop and optimize software using queue pairs, completion queues, memory registration, zero-copy I/O, and other RDMA primitives.
• Debug performance and reliability issues across applications, Linux kernel, drivers, NICs, DPUs, switches, and storage systems.
• Analyze network and storage behavior including latency, throughput, queueing, congestion, packet loss, retransmissions, and flow control.
• Develop mechanisms to improve network performance and congestion behavior in high-bandwidth RDMA fabrics.
• Build tooling and instrumentation to understand end-to-end performance across compute, network, and storage.
• Profile and tune systems across PCIe, NUMA, CPU, memory, NIC, DPU, network, and storage boundaries.
• Own major components from design through implementation, performance validation, and deployment.
