The Role:

The Reliability and Failure Analysis Technician will be responsible for performing detailed root cause analysis on Cerebras products and delivering comprehensive reports on findings. This role requires extensive hands-on lab work, including troubleshooting, measurement, precision inspection, repair, and assembly of company products and sub-assemblies. The Technician will execute product audits from the manufacturing line, perform GD&T-based dimensional inspections using CMM tools, and validate product functionality and reliability through structured testing and measurement experiments.

This position also supports reliability testing and AI hardware validation to ensure long-term performance, durability, and mechanical integrity under demanding AI workloads. Collaboration with Engineering, Manufacturing Engineering, Quality Assurance, and Technical Support teams is essential to drive continuous improvement and product insights.

Responsibilities:

• Conducts root cause failure analysis on Cerebras products and publishes detailed reports with supporting data, images, and conclusions.
  • Performs dimensional inspections and GD&T validation on critical mechanical and electronic assemblies using CMM, optical measurement tools, and precision gauges.
  • Executes cross-sectioning and microscopy analysis to identify solder joint defects, delamination, voiding, and interconnect quality across components and substrates.
  • Troubleshoots, repairs, and reworks complex assemblies at the component and board level, including electronic, thermal, and mechanical interfaces.
  • Designs and conducts measurement and correlation experiments to evaluate mechanical tolerance stack-ups, solder integrity, and part-to-part variability.
  • Performs reliability and AI hardware validation testing using temperature chambers, leak testers, pressure testers, and other specialized test tools to simulate operational conditions.
  • Conducts product audits from the manufacturing line, verifying both functional and dimensional conformity to design intent and reliability standards.
  • Manages and maintains Failure Analysis and Reliability Lab infrastructure, ensuring tools, fixtures, and instruments (CMM, X-ray, CSAM, microscopes) are calibrated and operational.
  • Supports documentation, training, and process improvement efforts across Reliability, Quality, and Manufacturing teams.

Skills & Qualifications:

• 10+ years of experience in a manufacturing, reliability, or lab environment, with 5+ years in testing, troubleshooting, measurement, and repair of high-complexity electronic or electromechanical systems.
  • Proven expertise in failure analysis methods (electrical, mechanical, and material), including fault isolation, signal tracing, and root cause determination.
  • Strong understanding of GD&T principles, dimensional tolerance analysis, and part inspection methods.
  • Hands-on experience with CMM, digital microscopes, laser profilometers, and precision measurement tools.
  • Skilled in cross-sectioning, polishing, and sample preparation for microstructural or solder joint analysis.
  • Proficiency in X-ray, CSAM, and optical microscopy for detecting voids, cracks, and interfacial defects.
  • Experience with AI hardware validation and reliability stress testing under thermal and mechanical load conditions.
  • Advanced soldering and desoldering skills (SMT, BGA, and lead-free).
  • Ability to read and interpret engineering drawings, schematics, and GD&T feature control frames.
  • Excellent analytical, documentation, and problem-solving skills.
  • Self-directed, detail-oriented, and able to collaborate effectively across multiple engineering disciplines.
