Posted 5 hours ago
About the role
- Senior Product Architect for HPE focusing on SONiC networking and AI data center solutions. Leading architectural strategy and cross-functional collaboration to enhance data center performance.
Responsibilities
- Architect ultra-low-latency, lossless Ethernet fabrics supporting tens of thousands of GPUs for AI training and inference.
- Own the end-to-end SONiC platform architecture and fabric strategy, spanning control plane, management plane, data-plane integration, and operations at scale.
- Define multi-generation fabric and platform strategy across switch ASICs, NICs, SerDes capabilities, cabling, and system constraints, aligned to power, performance, and deployment realities.
- Own link-level and physical-layer requirements as they impact SONiC performance, including high-speed PAM4 signaling (112G/224G), error handling, and hardware/software interaction.
- Align SONiC architectures with next-generation GPU, NIC, and switch platforms, ensuring optimal performance across hardware and software boundaries.
- Define SONiC capabilities for AI and HPC workloads, including lossless Ethernet and RoCE, congestion management, QoS, and ECN.
- Drive scale, performance, and resiliency targets for SONiC-based fabrics.
- Define and enforce system-level validation criteria, including scale testing, fault injection, performance benchmarking, and upgrade scenarios.
- Drive telemetry, observability, and proactive reliability across SONiC and underlying hardware.
- Lead cross-layer performance analysis and root-cause investigations spanning SONiC software, ASIC pipelines, SerDes behavior, power, and thermal interactions.
- Partner with ASIC vendors, system vendors, and internal platform teams to influence roadmaps and ensure SONiC readiness and scalability.
- Serve as a technical authority and cross-functional leader, translating architectural intent into clear product requirements and multi-generation roadmaps.
Requirements
- 10 plus years of experience in data center networking, AI infrastructure, or high-performance systems.
- Deep expertise in SONiC architecture and internals.
- Large-scale Ethernet fabrics.
- High-speed SerDes (112G/224G PAM4) and their impact on system performance.
- Strong understanding of ASIC pipelines, buffering, ECMP behavior, and congestion mechanisms.
- Proven ability to diagnose cross-layer performance and reliability issues.
- Hands-on experience with RDMA/RoCE, congestion control, and lossless Ethernet at scale.
- Experience with automation and tooling (Python, Ansible, Terraform) in large-scale environments.
- Industry certifications (e.g., CCIE, JNCIE, NVIDIA) or equivalent practical experience preferred.
Benefits
- Health & Wellbeing: comprehensive suite of benefits that supports physical, financial and emotional wellbeing.
- Personal & Professional Development: investment in career through specific programs helping reach career goals.
- Unconditional Inclusion: embrace individual uniqueness in the workplace.
