Senior Mechanical Engineer - Thermal Solutions Pay: $125,000-$137,500, annually Location: Based out of Springfield, MO CSI is looking for an experienced Senior Mechanical Engineer – Thermal Systems to lead the engineering of large skidded and packaged thermal equipment, including Coolant Distribution Units (CDUs) for direct-liquid-cooled data centers. This role owns thermal performance, hydraulic design, and mechanical and structural integrity from design basis through fabrication, testing, and field support. You’ll shape the product platforms, standards, and configurations that CSI builds, while partnering with Engineering, Manufacturing, Production, Supply Chain, and customer-facing teams. The position also supports CSI’s engineered-to-order equipment business serving food, dairy, beverage, personal care, pharmaceutical, biotech, and nutraceutical markets. This is an opportunity to take technical ownership of complex equipment, improve repeatability and manufacturability, and ensure the performance CSI communicates to customers is supported by accurate, documented engineering. What You’ll Be Doing Own thermal and fluid-system design bases, including heat exchanger sizing and rating, hydraulic models, pump and drive selection, operating limits, and supporting fluid-system components. Lead mechanical and structural design of large skids, including frames, equipment layouts, load distribution, lifting and transport requirements, materials, weld requirements, corrosion protection, and thermal expansion. Perform structural analyses using hand calculations and finite element methods, and prepare calculation packages for external engineering certification review. Serve as the engineering authority for assigned product platforms by resolving shop-floor design issues, dispositioning non-conformances, supporting factory acceptance testing, and improving design for manufacturing and assembly. Own platform configurations, revision control, engineering standards, calculation methods, and tools to support consistent, repeatable builds and reliable repeat orders. Prepare and validate the technical engineering content for quotes, proposals, datasheets, and specifications; ensure published performance figures are supported by documented engineering. Collaborate with customers and cross-functional teams throughout the project lifecycle, support start-up, commissioning, and field troubleshooting, and mentor engineers and designers in thermal, fluid-system, and skid design. Who This Is For You’re a technically strong engineer who takes ownership, works independently, and translates complex engineering requirements into safe, reliable, manufacturable equipment. Analytical problem-solver with strong applied heat-transfer, hydraulic-system, and mechanical design skills. Able to make sound engineering decisions, document calculations, and communicate technical information clearly. Collaborative partner who works effectively with production, manufacturing engineering, supply chain, controls, CAD/design, customers, and suppliers. Committed to safety, quality, compliance, continuous improvement, and helping others develop their technical capabilities. Required Education/Experience Bachelor’s degree in Mechanical Engineering required. 7+ years of mechanical engineering experience designing skidded or packaged fluid-handling, thermal, or industrial heat-transfer equipment from customer specification through fabrication, testing, and field start-up. Demonstrated depth in applied heat transfer and hydraulic system design, with working structural-analysis capability using hand calculations and finite element methods. Experience in data center liquid cooling, industrial refrigeration, or process cooling. Familiarity with AWS D1.1/D1.6, ASME B31.3, AISC, and ASME BTH-1; CSI will train a strong engineer on code application. Familiarity with hygienic equipment standards, including 3-A, EHEDG, and ASME BPE. Autodesk Inventor and Vault or equivalent 3D CAD and product data management tools preferred.
