Software Senior Principal Engineer

What you’ll achieve

As a Software Principal Engineer, you will lead the end-to-end engineering of Dell networking products and solutions for data center and AI fabric environments, driving innovation in a fast-paced development environment from requirements definition and architecture through development, validation, release, and customer deployment.

You will collaborate with platform, silicon, software, validation, solutions, and customer-facing teams to deliver next-generation Dell Enterprise SONiC capabilities for the high-performance network fabrics powering the Dell AI Factory. You will also apply AI-assisted engineering tools throughout the development lifecycle to accelerate delivery, improve quality, and enhance engineering productivity.

You will:

• Own complex networking features end to end, from requirements and architecture through validation and delivery of production-quality Dell Enterprise SONiC software.

• Architect and deliver large-scale data center and AI fabric capabilities on Dell PowerSwitch (800GbE/1.6TbE) platforms, including RoCEv2, congestion management, adaptive routing, SRv6, and dynamic load balancing.

• Troubleshoot complex system, scalability, performance, and customer issues across the control plane, data plane, SAI, and switch ASIC layers.

• Drive fabric automation and lifecycle management using REST APIs, gNMI/OpenConfig, YANG, Python, Ansible, ONIE, and ZTP, and apply Dell AI tools to speed development, testing, and debugging.

• Lead architecture and code reviews, mentor engineers, and work with global hardware, silicon, quality, product, and customer-facing teams to deliver reliable releases.

Take the first step towards your dream career

Every Dell Technologies team member brings something unique to the table. Here’s what we are looking for with this role:

Essential Requirements

• Bachelor’s or master’s degree in computer science, computer engineering, or a related discipline (or equivalent experience), with 12+ years developing networking software for enterprise, cloud, AI, and data center environments.

• Strong C/C++ and Python skills on Linux, with hands-on experience in SONiC or an equivalent network operating system, including containerized NOS architecture and SAI, and proven use of AI coding and testing tools.

• Deep knowledge of NPU architecture, packet processing, ACLs, QoS and buffer management, and ASIC programming through SAI/SDK, plus data center routing and switching (OSPF, IS-IS, BGP EVPN, VxLAN, SRv6, multicast, leaf-spine).

• Expertise in AI/HPC Ethernet fabrics, including RoCEv2, PFC, ECN/DCQCN, DCB, adaptive routing, dynamic load balancing, and fabric telemetry on 800GbE/1.6TbE merchant-silicon platforms, with an understanding of GPU, SmartNIC, and NCCL interoperability.

• Proven network automation skills (REST APIs, gNMI/OpenConfig, YANG, Python, Ansible, ONIE/ZTP, CI/CD), strong debugging and validation using packet captures and traffic generators, and demonstrated technical leadership and mentoring.

Desirable Requirements

• Experience with open-source networking projects, AI/ML tools, or the broader AI infrastructure ecosystem.

• Familiarity with Dell AI Factory solutions, PowerEdge AI servers, NVMe/TCP storage fabrics, and Kubernetes- or Slurm-based AI/HPC clusters.
