Manifold Engineer- Thermal & Fluid Systems

About the role

To support our extraordinary teams who build great products and contribute to our growth, we’re looking to add a Manifold Engineer located in Littleton, MA.

Responsibilities

• Design and develop fluid distribution manifolds for liquid cooling systems used in processors, servers, racks, and datacenter deployments.
• Perform CFD simulations and thermal-fluid modeling to optimize flow uniformity, pressure drop, and thermal performance.
• Select materials and components suitable for high-reliability, corrosion-resistant, and leak-proof operation.
• Integrate and specify quick disconnects, fluid seals, and other connectors for modularity, serviceability, and long-term reliability.
• Collaborate with mechanical and manufacturing engineers to ensure designs are scalable and cost-effective.
• Create and maintain detailed technical documentation, including CAD models, drawings, BOMs, and specifications.
• Work with suppliers and contract manufacturers to validate production processes and quality standards.
• Stay informed on emerging technologies in fluid distribution, sealing systems, and datacenter cooling infrastructure.
