We make the best chips physically possible for the large model needs of frontier labs.
About the role
Develop AI compute trays, rack enclosures, and mechanical assemblies in accordance with OCP Rack specifications Produce 3D models and 2D drawings at the component, sub-assembly, and assembly levels, and maintain the mechanical BOM, drawing packages, and GD&T documentation throughout the NPI stages
What they're looking for
- 5+ years of mechanical engineering experience in server, data center, or AI compute hardware
- Experience designing rack-scale hardware — compute trays, rack enclosures, or server platforms
- Familiarity with OCP Open Rack standards
- Experience with liquid cooling systems — cold plates, manifolds, or CDU interfaces
- Proficiency in 3D CAD (SolidWorks or equivalent) and GD&T
- Familiarity with sheet metal, extrusion, casting, and machining manufacturing processes
More about this role
MatX is building next-generation AI compute infrastructure for large-scale LLM training and inference. We are looking for a hands-on Mechanical Engineer to design, develop, and validate mechanical systems for our rack-scale AI platform from compute trays and rack enclosures to fully liquid-cooled infrastructure.
Develop AI compute trays, rack enclosures, and mechanical assemblies in accordance with OCP Rack specifications
Produce 3D models and 2D drawings at the component, sub-assembly, and assembly levels, and maintain the mechanical BOM, drawing packages, and GD&T documentation throughout the NPI stages
Design and integrate liquid cooling hardware including cold plates, manifolds, quick-disconnect fittings, and CDU-to-rack interfaces
Support the mechanical integration of compute trays into rack systems across power, liquid cooling, cabling, and connector interfaces
Carry out tolerance stack-up analysis at multiple levels, from package through rack, to confirm proper fit and straightforward assembly
Take a hands-on role in EVT, DVT, and PVT prototype builds, bring-up, and debug
Apply DFM/DFA principles and contribute to design reviews with JDM/ODM manufacturing partners
