Key Responsibilities
- Work with ODM partners to define and execute the manufacturing test strategy for L6 board-level production.
- Develop and review test plans covering:
- In-Circuit Test (ICT)
- Making Defect Analyzer (MDA)
- Board Functional Test
- Diagnostics coverage requirements
- Manufacturing line test flow
- Failure detection and containment strategy
- Ensure test plans provide appropriate coverage for board-level defects, assembly issues, component-level failures, and functional performance requirements.
- Partner with hardware engineering, design validation, diagnostics, operations, quality, and ODM teams to align manufacturing test coverage with product risk areas.
- Define requirements for board-level test stations, fixtures, test software, diagnostic content, and production test infrastructure.
- Support the development, validation, and release of board functional tests into the ODM manufacturing environment.
- Review ICT and MDA coverage reports and drive improvements to ensure adequate manufacturing defect detection.
- Define pass/fail criteria, test limits, data collection requirements, retest rules, and failure handling processes.
- Support bring-up, debug, and qualification of manufacturing test processes during NPI and production ramp.
- Support development and deployment of L10 system-level manufacturing test processes.
- Port board functional tests into the L10 manufacturing environment where appropriate.
- Ensure L10 test coverage validates system-level integration, board functionality, firmware readiness, thermal behavior, power behavior, I/O functionality, and platform health.
- Work with ODM and internal engineering teams to ensure test execution is scalable, repeatable, and suitable for high-volume server production.
- Specify manufacturing line requirements for test station configuration, test sequencing, data capture, networking, tooling, and operator workflow.
- Define requirements for test fixtures, cabling, adapters, load boards, debug interfaces, power delivery, signal access, and fixture maintenance.
- Ensure fixtures and test stations meet manufacturing requirements for reliability, repeatability, safety, ease of use, throughput, and serviceability.
- Drive fixture validation, correlation, preventive maintenance planning, and readiness for production ramp.
Quality Planning, Yield, and Continuous Improvement
- Create and maintain an overall manufacturing quality plan focused on yield, defect containment, test coverage, and production readiness.
- Monitor manufacturing test yield, first-pass yield, failure pareto trends, retest rates, false failures, and escape risks.
- Lead technical investigations into manufacturing test failures, quality excursions, and yield loss.
- Drive structured root cause analysis and corrective action with ODM partners and internal stakeholders.
- Define and track corrective actions, containment plans, and long-term process improvements.
- Establish best practices for test development, test deployment, fixture readiness, failure analysis, data review, and manufacturing quality control.
Cross-Functional Collaboration
- Serve as the primary technical interface between internal teams and ODM manufacturing test teams.
- Collaborate with hardware engineering, diagnostics, firmware, software, quality, supply chain, and operations teams.
- Support NPI builds, pilot builds, production ramp, and sustaining manufacturing activities.
- Communicate test readiness, risks, yield issues, corrective actions, and manufacturing quality status to program stakeholders.
- Travel to ODM manufacturing sites as needed to support build readiness, test deployment, debug, and ramp activities.
DIFFERENTIATORS
- 8+ years of experience in manufacturing test engineering, hardware test engineering, or production test development.
- Experience supporting high-volume server manufacturing or similar complex compute, networking, storage, or data center hardware products.
- Strong understanding of board-level manufacturing test processes, including:
- In-Circuit Test (ICT)
- Making Defect Analyzer (MDA)
- Board Functional Test
- Diagnostics test execution
- Manufacturing defect detection
- Experience working directly with ODM, CM, or JDM manufacturing partners.
- Hands-on experience with Linux-based test environments, including test execution, scripting, log collection, and failure triage.
- Familiarity with server hardware architecture, including CPUs, memory, storage, networking, BMCs, firmware, power subsystems, and high-speed interfaces.
- Experience defining test fixture requirements and supporting fixture bring-up, validation, and production readiness.
- Strong understanding of manufacturing quality metrics, including first-pass yield, retest rate, defect paretos, failure analysis, and corrective action.
- Demonstrated ability to drive root cause analysis and corrective action across engineering and manufacturing teams.
- Ability to review test logs, identify failure signatures, isolate issues, and determine whether failures are related to hardware, firmware, software, test process, or fixture design.
- Strong written and verbal communication skills with the ability to clearly communicate technical issues, risks, and action plans.
