Senior Staff Reliability Engineer (Silicon & Package)

Responsibilities & opportunities in this role:

Interconnect reliability

- Own the reliable high performance/ fine pitch interconnect, moving them from pathfinding to high-volume manufacturing.
- Drive Chip-Package Interaction (CPI) analysis, assessing how silicon-level stresses impact ELK layers and active circuitry.
- Lead Physics-of-Failure (PoF) assessments specifically for Cu-Cu diffusion, bond interface toughness, and dielectric reliability.

Qualification & Test Vehicle Architecture

- Architect reliability test vehicles (TVs): Define the specific Daisy Chain, Kelvin, and heater structures needed to characterize bond yields and reliability margins before the full product tape-out.
- Execute Silicon & Package qualification: manage the full suite of stress tests, merging standard package and silicon-specific reliability checks

Failure Analysis & Root Cause Engineering

- Direct complex Failure Analysis (FA) campaigns, utilizing high-resolution techniques to inspect sub-micron defects in the interconnect interface.
- Correlate electrical signatures to physical defects, distinguishing between process-related defects (voids, particles) and intrinsic reliability wear-out mechanisms.
- Lead the Feedback Loop: Translate FA findings into immediate design rule updates or process window adjustments to prevent recurrence.

External Partnership & Supply Chain Technical Leadership

- Lead technical engagements with Foundries and OSATs, ensuring their process control monitors (PCM) and reliability monitors align with your product requirements.
- Audit and uplift supplier capabilities, focusing on their ability to detect latent defects in advanced package assemblies.

Ideal candidates have/are:

Education: B.S. with 7+ years or M.S. with 5+ years of experience in Materials Science, Mechanical Engineering, Physics, or Electrical Engineering.
Packaging Expertise: Proven end-to-end ownership of electronic packaging reliability for AI/HPC applications, specifically with advanced package architectures.
Reliability Simulation: fundamental knowledge in Finite Element Analysis (FEA) using tools like ANSYS or Abaqus for thermal-mechanical stress modeling, warpage prediction, and fracture mechanics (replacing the previous CFD requirement).
Standards & Testing: Deep familiarity with industry standards (e.g., JEDEC JESD47, JESD22, IPC) and experience defining qualification plans including TC, HTS, HAST/uHAST, and HTOL.
Silicon Reliability: Understanding of silicon-level reliability mechanisms (e.g., Electromigration (EM), Stress Migration (SM), TDDB) and how they interact with packaging stresses.

Preferred Qualifications

Advanced Interconnects: Direct hands-on experience qualifying advanced interconnects and processes and reliability.
Statistical Analysis: Proficiency with statistical analysis software (e.g., JMP, ReliaSoft, Weibull++) for lifetime prediction and reliability modeling.
Coding/Automation: Experience with Python, MATLAB, or SQL for parsing large reliability datasets and automating data analysis.
Foundry/OSAT Experience: Previous experience working directly with major foundries or OSATs on advanced node qualification.
Material Science: Deep knowledge of underfill properties, mold compounds, and CTE mismatch challenges in heterogeneous integration.
