Job summary

Avicena Tech in Sunnyvale, CA is seeking a Failure Analysis Engineer to isolate, characterize, and root-cause failures in GaN microLEDs and photodetector arrays. You will drive end-to-end FA from failure isolation to corrective actions, informing design, process, packaging, and reliability teams.

The role requires 5–8+ years in FA for semiconductor/optoelectronic devices, strong data analysis (Python/MATLAB), and deep device physics knowledge.

Qualifications

• MS or PhD in Electrical Engineering, Materials Science, Physics, or related field.
• 5–8+ years of failure analysis experience in semiconductor, optoelectronic, or photonic devices.
• Root-cause rigor: 8D, fishbone, fault-tree investigations to definitive physical conclusions.
• Device physics: understanding of semiconductor and optoelectronic device physics and failure mechanisms.
• Data analysis and scripting (Python, MATLAB) and clear technical communication.

Responsibilities

• Lead end-to-end failure analysis of GaN microLEDs, photodetector arrays, and interconnect modules from isolation to root cause and corrective action.
• Plan and perform electrical, optical, and physical FA including EL/PL imaging, SIMS, EMMI/photoemission, OBIRCH/thermal, curve tracing, and fault localization.
• Direct cross-sectioning and imaging (FIB, SEM, TEM, EDX, CT) to identify defects and interface issues.
• Build failure signatures and defect libraries; distinguish process-, design-, and stress-induced failures.
• Translate FA findings into actionable recommendations for device, process, packaging, and reliability teams; verify corrective actions.
• Produce clear FA reports and present root-cause conclusions to engineering and leadership.
