Mechanical Principal  Engineer – AI Technologies

Mechanical Principal  Engineer – AI Technologies

Thermal / Mechanical Engineering leads and delivers the development of innovative and compliant mechanical design solutions, as well as cross-functional interfaces for datacenter and server computer systems and peripherals. Our team conducts the analysis, feasibility studies and testing of mechanical products, instruments, subassemblies and packaging for new and existing products – and then oversees the introduction of design changes to the manufacturing organizations.

Join us to do the best work of your career and make a profound social impact as a Mechanical Principal  Engineer on our Mechanical Engineering Team in Austin, Texas.

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.

What you’ll achieve

This role is critical to enabling next-generation AI and high-density computing by ensuring reliable, efficient, and scalable thermal solutions. You will directly influence customer success and shape the future of data center cooling technologies.

We are seeking a highly skilled Mechanical / Thermal Engineer specializing in Direct Liquid Cooling (DLC) to support customer-facing deployments of advanced data center infrastructure. This role bridges engineering design, system integration, and customer engagement, ensuring optimal thermal performance and reliability of high-density compute platforms. The ideal candidate will work directly with customers, internal engineering teams, and partners to deliver innovative cooling solutions at scale.

You will:

• Serve as the technical subject matter expert (SME) for mechanical and thermal systems, with a focus on DLC technologies in customer environments
• Lead customer engagements, including design reviews, site readiness assessments, and deployment support for liquid-cooled systems
• Collaborate with cross-functional teams (electrical, systems, manufacturing, and field engineering) to ensure end-to-end thermal solution delivery; influence product design by incorporating customer feedback and field learnings into next-generation solutions
• Analyze and optimize thermal performance of racks, servers, and cooling distribution units (CDUs) under real-world operating conditions; develop and present technical documentation, whitepapers, and customer-facing materials
• Support installation, commissioning, and troubleshooting of DLC systems, including manifolds, cold plates, and facility integration; provide root cause analysis and corrective actions for thermal or mechanical issues encountered during deployments
