Job description

Principal Mechanical Engineer – Data Centers

Remote – United States

Rosenthal Search Partners is supporting a data center developer in the appointment of a Principal Mechanical Engineer to take technical ownership across its growing portfolio of mission-critical infrastructure projects. This is a senior, hands‑on engineering position for someone who wants to operate at the forefront of data center cooling and mechanical infrastructure while having genuine influence over how major projects are designed and delivered.

The position is 100% remote within the United States, with travel as required, and offers a highly competitive compensation package including equity ownership.

The Opportunity

The Principal Mechanical Engineer will act as a key technical authority across the mechanical discipline, working across the development, design, construction and commissioning lifecycle of data center projects.

Rather than simply coordinating external consultants, you will be expected to understand the engineering in depth, challenge design decisions, review technical deliverables and help establish the mechanical solutions ultimately deployed across projects.

The position will have significant exposure to both traditional mission‑critical cooling infrastructure and the next generation of high‑density and liquid‑cooled data center environments.

What We're Looking For

• Bachelor's degree in Mechanical Engineering
• 8+ years of relevant mechanical engineering experience within mission‑critical / data center environments
• Experience supporting multiple hyperscale or colocation data center projects through construction and commissioning
• Strong technical knowledge of chilled‑water plants, air‑cooled and water‑cooled chillers, economization strategies and CRAH / fan‑wall systems
• Direct experience with liquid cooling technologies, including CDUs, facility water loops, rear‑door heat exchangers and direct‑to‑chip cooling
• Strong understanding of mechanical redundancy and resiliency strategies including N+1, 2N and concurrent maintainability
• Understanding of how mechanical infrastructure and redundancy interact with electrical system architecture
• Strong working knowledge of relevant ASHRAE data center thermal and energy‑efficiency standards
• Experience technically reviewing engineering designs throughout the major stages of design development
• Ability to review, challenge and provide direction to external engineering and design partners
• Strong understanding of mechanical system performance, reliability and efficiency within mission‑critical environments

Experience with CFD modeling, advanced commissioning / integrated systems testing, water‑use efficiency and BMS control strategies would be highly advantageous.

Why Consider It?

This is an opportunity to move beyond being one engineer within a large organization and take genuine technical ownership over the mechanical infrastructure supporting major data center developments.

The successful candidate will have the opportunity to influence mechanical design decisions from the earliest stages of development through construction and commissioning, including the deployment of next‑generation cooling technologies.

The package includes:

• 100% remote working within the United States
• Equity ownership
• Highly competitive base compensation
• Significant technical ownership and autonomy
• Opportunity to work extensively with liquid cooling and high‑density compute infrastructure
• Direct influence over engineering standards and project design
• Long‑term career opportunity within a growing data center development platform
