Senior Mechanical Design Engineer

SoTalent is seeking an experienced Senior Mechanical Design Engineer to lead the design and integration of advanced liquid-cooled infrastructure for hyperscale data centers. The role involves solving complex engineering challenges, driving innovation, and shaping next-generation cooling technologies.

Responsibilities:

• Lead end‑to‑end mechanical design for liquid‑cooled racks, CDUs, manifolds, structural frames, and hydronic piping systems
• Serve as the expert in single-phase and two-phase liquid cooling, including loop architecture and in‑rack distribution
• Define and validate mechanical performance requirements—pressure, temperature, flow, hydrostatic integrity, and serviceability
• Perform stress analysis, FEA, flow modeling, and structural load calculations for machined, welded, and structural components
• Drive material selection for wetted systems with a focus on corrosion resistance, surface treatments, and long‑term durability
• Build and review detailed CAD designs (CREO, SolidWorks) and complete technical documentation for manufacturability and integration
• Develop specifications for hydronic components and cooling infrastructure aligned with industry standards (ASME, ISO)
• Lead validation activities including hydrostatic testing, leak detection, flow resistance checks, and corrosion verification
• Evaluate customer requirements for feasibility, cost, manufacturability, and overall design optimization
• Collaborate closely with thermal, electrical, manufacturing, quality, and supply chain teams for system‑level integration
• Improve manifold and assembly processes—machining, welding, sealing, venting, draining, and flow path optimization
• Support production scaling, root-cause investigations, and continuous improvement initiatives
• Provide technical leadership in supplier qualification and manage engineering risks across performance, schedule, and cost
• Contribute to R&D efforts advancing next‑gen liquid cooling technologies

Requirements:

• Bachelor's degree in Mechanical Engineering or related field
• 8+ years of experience in mechanical design and system integration
• Proven success delivering complex engineered systems
• Strong understanding of mechanical systems, integration strategies, and reliability engineering
• Familiarity with data center or mission‑critical infrastructure (preferred)
• Excellent problem‑solving, communication, and teamwork skills
• Master's degree in Mechanical Engineering
• Professional Engineer (PE) License
