Sr. Mechanical Engineer-Houston, USA [Hybrid]

About the role

We are seeking a Senior Mechanical Engineer to lead the design and integration of advanced liquid-cooled rack systems for large-scale AI and HPC deployments. This role is pivotal in defining rack-level mechanical architectures supporting high power compute racks to be integrated in traditional and modular data centers (MDC).

Responsibilities

• Define and lead mechanical architecture development for liquid-cooled racks, including manifolds, server interfaces, and facility connections.
• Drive system, rack-level, and data center integration, ensuring compliance with performance, safety, structural, shock/vibration, seismic and reliability targets.
• Partner with rack suppliers and internal design teams to co-develop mechanical designs aligned with company standards for performance, usability, and cost.
• Perform or coordinate thermal-hydraulic analysis to optimize loop design, flow distribution, and cooling efficiency.
• Own CAD design, documentation, and release of mechanical components and assemblies.
• Lead engineering validation activities, including test plan creation, prototype builds, and root-cause analysis of design or integration issues.
• Conduct design reviews to ensure manufacturability and compliance with mechanical standards and best practices (DFM, DFR, and serviceability).
• Collaborate with system architecture, electrical, and manufacturing engineering teams to deliver a balanced and high-performance rack solution.

Requirements

• BS or MS in Mechanical Engineering or related field with 8+ years of experience in mechanical design for high-density electronics or data center systems.
• Proficiency in thermal-fluid systems design, mechanical packaging, and system-level integration.
• Strong experience with CAD tools (Creo or SolidWorks) and simulation tools for thermal, flow, or structural analysis (Flotherm, ANSYS, or equivalent).
• Proven success collaborating with external rack or cooling solution suppliers, managing specs, reviews, and validation of deliverables.
• Familiarity with bracketing, containers, vibration isolation, FEA, rigging/lifting, liquid cooling infrastructure in data centers, including CDU, manifold, facility water, and interconnect standards.
• Excellent communication and project leadership skills across cross-functional engineering disciplines.

Preferred Qualifications

• Experience developing high-power compute rack solutions or liquid cooling architectures in OEM or hyperscale environments.
• Knowledge of heat transfer and fluid mechanics as applied to electronic cooling solutions.
• Experience with material compatibility, system reliability, and environmental compliance requirements for global deployment.
• Hands-on understanding of prototype build, instrumented testing, and system qualification processes.
• Modular Data Center (MDC) knowledge and experience is a plus.

What we offer

• A attractive compensation package reflecting your expertise and experience.
• Medical Insurance Plan.
• 401k Employee volunteer contribution Plan.
• A great work environment characterized by friendliness, international diversity, flexibility, and a hybrid-friendly approach.
