About The Position

Join Dell Technologies’ Network Engineer Hardware team in Franklin, Massachusetts, or Austin, Texas, as a Thermal Senior Principal Engineer. The role focuses on thermal architecture, design, and validation for next-generation Network Switches (L10) and Network L11 integrated rack solutions. You will work across mechanical, electrical, hardware, power, and system engineering teams to develop cooling solutions for high-performance networking platforms used for AI, HPC, and cloud workloads.

Using thermal simulation, laboratory testing, characterization, and data-driven analysis, you will evaluate product concepts, assess thermal feasibility, and optimize system performance, reliability, and efficiency. The position includes ownership of key thermal technologies and roadmaps supporting future networking, optics, and rack-scale infrastructure solutions.

Dell describes an engineering environment focused on experimentation, rapid feedback, customer-first product development, and using AI to support development work. The listed salary range is $164,000–$226,000. Benefits information is available through MyWellatDell.com, but specific benefits are not enumerated in the posting.

Requirements

• Bachelor’s or master’s degree in Mechanical Engineering with a focus on thermal engineering.
• At least 8 years of relevant industry experience.
• Experience in CFD modeling for internal flow and electronic cooling applications.
• Proven experience instrumenting thermal tests and developing test plans.
• Strong communication skills with multidisciplinary teams.
• Strong drive to work through challenging compromises to achieve an optimal thermal solution.

Nice To Haves

• Experience working with CREO.
• Experience with air and liquid cooling in the server or network electronics industry.
• Knowledge of cooling requirements for GPUs, CPUs, NPUs, or rack L11 systems.

Responsibilities

• Align with key stakeholders on product requirements, performance metrics, and boundary conditions.
• Develop approaches to evaluate thermal aspects of product concepts while considering prototype availability, product schedules, and thermal risks.
• Develop thermal solutions internally or with vendor partners, including heat sinks, cold plates, air movers, air shrouds, sealing, thermal interface materials, venting, and thermal controls.
• Present findings to thermal engineers and management to identify problem areas and opportunities to improve cost, power, and cooling efficiency.
• Follow existing product-development practices and procedures, and develop or improve them when necessary or desirable.
• Own key thermal technologies and roadmaps for future generations of networking, optics, and rack-scale infrastructure solutions.
