Job summary

Accelsius is seeking a Liquid Cooling Mechanical Engineer to design server-level liquid cooling hardware for AI/HPC platforms, including cold plate loops, manifolds, and pressure-containing assemblies. The engineer will take designs from first prototype to production, collaborating with thermal engineers, suppliers, and manufacturing teams.

This role reports to the Server Cooling Product Manager and requires hands-on ownership of designs across disciplines.

Qualifications

• Bachelor’s degree in mechanical engineering or similar required.
• Direct experience designing liquid cooling hardware for data center servers or racks required (single-phase or two-phase).
• Demonstrated design of pressure-containing fluid systems: joint design, fitting selection, material selection, pressure rating, and leak testing.
• Working knowledge of fluid mechanics and heat transfer; CFD/thermal specialization not required.
• Proficiency in a parametric 3D CAD tool (SolidWorks preferred) and producing manufacturing drawings with GD&T.
• FEA experience evaluating deformation and stress in mechanical parts.
• Record of taking designs through fabrication and release with external suppliers.

Responsibilities

• Design and CAD: translate prototypes to production-ready designs, including cold plate loops, tubing, manifolds, and fittings.
• Lead design reviews and mentor engineers on server plumbing design.
• Produce production-ready 3D models, drawings with GD&T, and BOMs; manage revisions in PLM.
• Work with suppliers and fabrication shops from RFQ through first article; drive DFM.
