Top Mechanical Design Engineer Jobs in Chicago, IL

Develop thermal-hydraulic models for scientific apparatus using ASME B31.3-2022 for installation at a research reactor. Perform steady-state and transient temperature modeling, work independently, and coordinate with EPC contractors and vendors on costs and budgets. The role is remote, part-time, and temporary, with at least four required site visits to State College, Pennsylvania. U.S. citizenship, background screening, drug-free status, and references are required.

Designs mechanical and electromechanical test fixtures, tooling, and related hardware for optical networking products. Responsibilities include CAD modeling, engineering drawings, BOMs, configuration-controlled documentation, engineering analysis, tolerance studies, fabrication support, assembly, troubleshooting, validation, and deployment. The role collaborates with engineers, technicians, suppliers, and manufacturing partners to deliver reliable, manufacturable solutions throughout the product development lifecycle.

Lead the architecture, hydraulic design, documentation, integration, manufacturing readiness, controls coordination, and commissioning of liquid-cooling and mechanical distribution systems for modular AI data centers. Own P&IDs, calculations, equipment and valve schedules, interfaces, standards, and performance validation. Collaborate with thermal, electrical, controls, manufacturing, commissioning, supply chain, OEM, and field teams to create scalable, serviceable, repeatable systems for deployment across multiple sites.

Own mechanical design, documentation, and commissioning for industrial automation systems, robotic equipment, conveyors, material-handling systems, and EOAT. Responsibilities include SolidWorks modeling, drawings, BOM management, prototyping, assembly, system integration, troubleshooting, testing, root-cause analysis, design for manufacturability, vendor coordination, and supporting product improvements. The role is hands-on and requires shop-floor work, cross-functional collaboration, on-site work near Chicago, and travel up to 25%.
