About the Role
We are building next-generation liquid cooling infrastructure for AI Data Centers, enabling high-density GPU, HPC, and accelerated computing settings.
We are looking for a Design Engineer – CDU to own the mechanical design and product development of Coolant Distribution Units (CDUs) and associated liquid-cooling systems.

This role will work across concept development, CAD design, thermal and hydraulic engineering, component selection, prototyping, testing, DFM/DFA, and manufacturing to take CDU products from engineering concept to production.

Key Responsibilities
Design and develop Coolant Distribution Units (CDUs) for high-density AI/HPC data centers.
Develop mechanical architecture for CDU systems including pumps, heat exchangers, valves, manifolds, filters, expansion tanks, sensors, piping, fittings, and control components.
Create detailed 3D CAD models, assemblies, drawings, BOMs,



and manufacturing documentation.
Develop and maintain P&IDs;, system schematics, flow diagrams, and mechanical layouts.
Perform thermal and hydraulic calculations for flow rate, pressure drop, heat load, heat exchanger sizing, pump selection, and system performance.
Select and evaluate pumps, heat exchangers, valves, sensors, actuators, quick disconnects, hoses, pipes, and other fluid-system components.
Design manifolds, piping systems, brackets, enclosures, frames, and sheet-metal/fabricated components.
Work with CFD/thermal engineering teams to optimize CDU flow distribution, pressure drop, heat transfer, and thermal performance.
Design products considering Design for Manufacturing (DFM), Design for Assembly (DFA), serviceability, reliability, and cost.
Develop prototypes and coordinate with vendors and manufacturing teams for fabrication and assembly.
Conduct pressure, leak, flow, thermal,
