Software Engineering General Summary:

Qualcomm is seeking a Principal Engineer to serve as the technical authority for scale‑out networking in next‑generation AI accelerator platforms. This role owns the architecture, implementation, and partner alignment of multi‑server scale‑out systems , spanning NICs, firmware, Linux kernel drivers, user‑space libraries, and runtime integration . Unlike traditional NIC‑centric roles, this position focuses on end‑to‑end scale‑out system design , including RoCE‑based transports , UAL , and ESUN , with responsibility across hardware, firmware, and host software layers. Key Responsibilities End‑to‑End Scale‑Out Architecture Act as principal technical owner for multi‑server scale‑out networking architecture Define and evolve RoCE‑based RDMA data paths for AI inference and distributed workloads Drive system‑level tradeoffs across: NICs and switches PCIe and DMA paths Firmware, Linux kernel drivers, and user‑space libraries Firmware, Driver, and Host Software Leadership Architect and review: RoCE / RDMA kernel drivers Firmware interfaces enabling peer‑to‑peer and zero‑copy transfers User‑space transport abstractions (e.g., UAL, ESUN) Debug and optimize performance across: Firmware driver user space Latency, congestion, ordering, and buffer management Influence upstream or ecosystem‑level designs where appropriate Partner & Ecosystem Engagement Serve as Qualcomm's principal technical interface with: NIC vendors and switch vendors Silicon and platform partners Lead deep technical design‑ins, architecture reviews, and production escalations Translate partner and field learnings into platform and firmware roadmaps Execution & Technical Influence Drive complex cross‑org efforts from concept to production enablement Identify architectural risks early and lead mitigation Mentor senior engineers through design and architecture reviews Required Qualifications BS/MS in Computer Engineering, Electrical Engineering, Computer Science, or equivalent experience 10-15+ years experience in system software, networking, or platform engineering Proven experience building scale‑out server or cluster architectures Strong hands‑on experience with: Linux kernel networking and drivers RDMA / RoCE stacks (kernel and user space) Firmware‑software interfaces Excellent systems‑level debugging skills across

HW/FW/OS

boundaries Preferred Qualifications Hands‑on experience with: libibverbs, RDMA core, RoCE drivers, and firmware UAL, ESUN, or similar transport/runtime abstractions Background in AI, HPC, or accelerator‑based platforms Experience enabling multi‑server inference or disaggregated serving Strong C/C++ systems programming background (x86 and ARM64)
