About The Position

Jabil is seeking a Senior Manufacturing Test Engineer with hands-on experience testing and troubleshooting enterprise server, storage, networking, GPU, or AI compute platforms in a manufacturing or production environment, with a focus on liquid cooling technology. The role develops, integrates, and continuously improves next-generation compute platforms, including AI/ML, GPGPU, server, networking, and storage systems. It leads test engineering activities in a high-volume manufacturing environment, advancing product quality, system performance, and operational excellence through troubleshooting, automation, and team leadership. This is not a software QA, application testing, or web-services testing role. The engineer designs and maintains factory test procedures and systems, supports failure analysis, NPI readiness and production ramp, and applies Linux, scripting, hardware diagnostics, networking, and production data analysis. Liquid cooling work involves applying thermal and fluid principles to cooling systems and working with associated components, instrumentation, safety practices, standards, and facility systems. The role also leads and develops engineers and technicians, manages performance, aligns engineering strategy with business goals, and drives operational improvements. The position is based onsite in Florence, Kentucky, with a combination of office and manufacturing-floor work in a modern, climate-controlled production environment. The role involves frequent movement on the manufacturing floor, lifting and carrying up to 50 pounds, and extended computer use. Required PPE includes safety shoes, eyewear, hearing protection, and an ESD vest; production areas have moderate noise levels.

Requirements

Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field is preferred; alternatively, a master’s degree and 2 years of experience.
5–10+ years of experience in test engineering, failure analysis, or hardware validation in manufacturing environments.
Experience with server, networking, and storage systems.
Experience in Linux environments and scripting with Python and/or Bash.
Experience supporting high-volume production and NPI.
Experience presenting technical data and leading cross-functional discussions.
Manufacturing test development for enterprise servers, storage, networking, or AI/GPU platforms.
Linux administration and command-line troubleshooting expertise.
Hardware failure analysis and server hardware diagnostics.
Experience with factory test automation and production ramp support.
Knowledge of JSON, system logs, and automation frameworks.
Strong understanding of compute architecture and server platforms.
Networking knowledge including switches, routers, optical systems, IP, and Layer 3.
Strong analytical, troubleshooting, and statistical analysis skills.
Proficiency in Excel and Power BI.
Ability to lift and carry up to 50 pounds.
Ability to work extended periods on computer systems and move frequently, including walking on the manufacturing floor.
