Thermal 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.

Responsibilities

Thermal Senior Principal Engineer

Join us as a Thermal Senior Principal Engineer on our Network Engineer Hardware team in Franklin, MA or Austin, TX to do the best work of your career and make a profound social impact.

What you'll achieve

As a Thermal Engineer, you will be responsible for the thermal architecture, design, and validation of Dell's next-generation Network Switches (L10) and Network L11 integrated rack solutions.

Working across mechanical, electrical, hardware, power, and system engineering teams, you will develop innovative cooling solutions for high-performance networking platforms supporting AI, HPC, and cloud workloads.

Utilizing thermal simulation, laboratory testing, characterization, and data-driven analysis, you will evaluate product concepts, drive thermal feasibility assessments, and optimize system performance, reliability, and efficiency.

The role includes ownership of key thermal technologies and roadmaps that enable future generations of networking, optics, and rack-scale infrastructure solutions.

You will:
