Software Senior Principal Engineer

Infrastructure Solutions Group (ISG) builds the products that power infrastructure, solutions, and data management our customers need most. Our teams design and develop the hardware and software that connect infrastructure, accelerate computational workloads, integrate across the stack, protect data continuity, and deliver the platforms, applications, and diagnostics our customers rely on every day at enterprise scale.

Some product builders follow the rules. Ours rewrite them.

Within ISG, innovation isn't just about creating new technology- it's about challenging assumptions and reimagining how work gets done. Engineers define intent, author precise specifications, and orchestrate AI agents that execute at speed and scale. AI is embedded throughout our development process, helping us move faster, learn quicker, and deliver greater impact. Yet the most important contribution remains uniquely human: deciding what to build, designing how it should work, and applying the judgment needed to earn our customers' trust. When your products power critical infrastructure around the world, that responsibility matters.

We move quickly toward the work that matters most. We reward experimentation, encourage bold thinking, and remove unnecessary barriers so great ideas can become reality faster. Our teams embrace a customer-first, first-to-market mindset, transforming rapid feedback into better products and better outcomes. We aren't looking for people who are content with the status quo- we look for builders who question it, improve it, and occasionally rewrite it.

If you're energized by solving complex systems challenges, excited to work alongside AI to amplify your impact, and motivated by the opportunity to shape what's next instead of simply maintaining what's been done before, you'll find your place here.

Join us and help build the future of enterprise technology.

Join us as a Software Principal Engineer on our Networking team in Chennai/Bangalore to do the best work of your career and make a profound social impact.

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.
