About the Role

You will support high-volume server manufacturing from board-level through system-level production testing. You will define, implement, validate, and optimize test strategies with ODM partners; develop test plans and infrastructure; specify fixtures and manufacturing lines; monitor yield and quality; investigate failures; and drive corrective actions through NPI, production ramp, and sustaining manufacturing.

Requirements

  • 8+ years of manufacturing test engineering, hardware test engineering, or production test development experience
  • Experience supporting high-volume server manufacturing or comparable compute, networking, storage, or datacenter hardware
  • Understanding of ICT, MDA, board functional testing, diagnostic test execution, and manufacturing defect detection
  • Experience working with ODM, CM, or JDM manufacturing partners
  • Hands-on experience with Linux-based test environments
  • Experience with test execution, scripting, log collection, and failure triage
  • Familiarity with server hardware architecture, CPUs, memory, storage, networking, BMCs, firmware, power subsystems, and high-speed interfaces
  • Experience defining test fixture requirements and supporting fixture bring-up and validation
  • Understanding of first-pass yield, retest rate, defect paretos, failure analysis, and corrective action
  • Root-cause analysis and corrective-action experience
  • Ability to review test logs and isolate hardware, firmware, software, process, or fixture issues
  • Experience with Python, Bash, or other scripting languages
  • Knowledge of manufacturing data systems, test-result databases, yield dashboards, and factory analytics
  • Experience with NPI, EVT, DVT, PVT, pilot builds, and production ramp
  • Familiarity with test coverage analysis, DFT, DFM, and manufacturing escape prevention

Responsibilities

  • Define and execute manufacturing test strategies with ODM partners
  • Develop and review ICT, MDA, board functional test, diagnostic coverage, line-flow, and failure-containment plans
  • Define requirements for test stations, fixtures, test software, diagnostic content, and production infrastructure
  • Deploy and validate board functional tests in ODM manufacturing environments
  • Review coverage reports and improve manufacturing defect detection
  • Define pass/fail criteria, test limits, data collection, retest rules, and failure-handling processes
  • Support manufacturing test bring-up, debugging, and qualification during NPI and production ramp
  • Deploy L10 system-level manufacturing test processes
  • Port board functional tests into L10 manufacturing environments
  • Specify line, station, fixture, cabling, tooling, data-capture, networking, and operator-workflow requirements
  • Drive fixture validation, correlation, maintenance planning, and production readiness
  • Monitor yield, failure paretos, retest rates, false failures, and escape risks
  • Lead investigations into test failures, quality excursions, and yield loss
  • Drive root-cause analysis, containment, corrective action, and process improvements
  • Support NPI builds, pilot builds, production ramp, and sustaining manufacturing
  • Communicate test readiness, risks, yield issues, and quality status

  • Dental coverage
  • Vision coverage
  • Flexible Spending Accounts
  • Health Savings Accounts
  • Disability insurance
  • Life insurance
  • 401(k) retirement plan
  • Commuter benefits
