Senior Manufacturing Test Engineer – Liquid Cooling

About the role

Jabil is seeking a Senior Manufacturing Test Engineer focused on liquid cooling, based on-site in Florence, KY. The role tests and troubleshoots enterprise server, storage, networking, GPU and AI compute platforms in a high-volume manufacturing environment, working directly with liquid cooling technology. It is not a software QA, application or web-services testing position.

Key responsibilities

• Design, develop and maintain test procedures, test systems, hardware and software for advanced compute platforms, and lead failure analysis and root cause investigations.
• Troubleshoot server, networking, storage and accelerator systems, and support AI/ML, GPU and high-performance compute platforms through integration and production.
• Develop and deploy automation with Python and Bash scripting, and analyze manufacturing and system data with Excel and Power BI.
• Support NPI readiness and production ramp, and present technical findings to stakeholders and customers.
• Configure and troubleshoot networking systems (switches, routers, LAN/WAN, Layer 3) and optical networking technologies, and train others on Linux command-line tools.
• Apply heat transfer, thermodynamics and fluid mechanics principles to liquid cooling systems, using pumps, cold plates, chillers, reservoirs, tubing and coolants such as PG25, and perform leak detection, material compatibility analysis and coolant safety procedures.
• Support immersion and direct-to-chip cooling, and work with OCP standards, BMS/SCADA systems and equipment such as particle analyzers, pressure testers and fill/flush/purge systems.
• Lead, mentor and recruit test engineers and technicians, set measurable goals, coach and evaluate performance, and align test strategy with site and organizational goals.
• Apply LEAN manufacturing principles, quality metrics (yield, GRR, DPPM) and process optimization to improve productivity, quality and cost.

Required profile

• Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science or a related field (preferred); or Master's degree with 2 years of experience.
• 5-10+ years in test engineering, failure analysis or hardware validation in manufacturing environments.
• Relevant experience includes manufacturing test development, hardware validation, production test, server test, rack integration test, or similar roles.

Required skills

• Linux environments and scripting (Python, Bash)
• Server, networking and storage systems, and hardware failure analysis
• NPI and production ramp support, factory test automation and server hardware diagnostics
• Knowledge of JSON, system logs and automation frameworks
• Networking knowledge (switches, routers, optical systems, IP, Layer 3)
• Excel and Power BI

Physical demands include frequent movement on the manufacturing floor, lifting up to 50 lbs, extended computer work, and wearing safety shoes, eyewear, hearing protection and an ESD vest in a moderate-noise production environment.
