Principal Manufacturing Test Engineer

** About

The Role
** ZT Systems is entering a new chapter of growth fueled by the next generation of hyperscale AI systems. These rack-scale, liquid-cooled, and highly interconnected architectures demand smart factories with integrated human–machine interfaces and deep, data-rich environments that deliver both reliability and innovation. We are seeking technical leaders with a quality mindset across multiple engineering disciplines to help shape this future — combining our culture of execution with new strengths in metrology, mechatronics, and test architecture to build advanced automation, predictive analytics, and AI-enabled processes that redefine how customer experience is delivered.
** What You Will Do
** The Principal Manufacturing Test Engineer will lead the strategy, development, and execution of test systems for hyperscale hardware products across all stages of production - from individual assembly modules to full server racks and clusters. They will deploy automation, advanced analytics, and Design-for-Test principles to create scalable systems that ensure seamless launches and zero-defect performance.
* Lead or contribute to transformation initiatives, helping set new standards for how ZT approaches manufacturing risk analysis, quality, and continuous improvement.
* Define and implement new systems, processes, or frameworks that support the smart factory vision, including automation, metrology, advanced inspection and testing, and predictive analytics.
* Collaborate across design, quality, manufacturing, test, and supplier engineering to drive solutions that integrate seamlessly into production.
* Leverage deep, data-rich environments and tools to generate insights; drive continuous improvement to yield, reliability, and throughput using root cause analysis and TTF (Time to Failure) insights.
* Apply advanced statistical and analytical methods to identify, quantify, and control risk in complex manufacturing environments.
* Translate DFM and PFMEA outputs into actionable process controls, ensuring proactive prevention of variation rather than reactive correction.
* Develop and execute comprehensive test strategies for all levels of hyperscale product assembly: module, server, rack, and cluster.
* Create and Strategy and lead the development and execution of cluster-level validation testing.
* Define and implement Best-in-Class manufacturing test practices and create a clear roadmap to achieve them.
* Nurture outside the box thinking and create a risk-taking culture to enable the creation of leading-edge test processes and utilities.
* Serve as SME for understanding customer product design, along with test and infrastructure requirements.
* Create and own the Design-for-Test (DFT) strategy across all products.
* Coach and nurture global test stakeholders to maximize their potential and facilitate a culture of learning and growth. Act as a thought partner and subject matter expert to refine ideas, generate hypotheses, and analyze data to formulate solutions.
* Design and oversee the deployment of high-reliability factory test infrastructure and test stations (manual, automated, and semi-automated).
* Specify and manage Test Management and Execution Software to coordinate diagnostics, test workflows, and reporting. Specify, develop, and maintain Test Executive test automation software for module and system-level testing.
* Lead the integration of customer test requirements, software, and infrastructure into factory systems.
* Create and maintain comprehensive test plans and test coverage reports.
* Drive the adoption of industry-standard and open-source test tools.
* Create industry leading low-level tests, utilities, and diagnostics at the module and board-level
* Champion automation across test stages to improve cycle time, test coverage, and yield* "Develop and optimize Server- and Rack-Level Tests including:
* Assembly line verification (including supplementation with automated inspection tools)
* BOM & Configuration Validation
* Firmware Updates (in-band, out-of-band, fixture-based)
* System Stress Testing and Burn-In
* Integration of customer supplied test"
* Optimize test cycle times through TTF…
