Failure Analysis Engineer

The Allegro team is united by a clear purpose—advancing technologies that make the world safer, more efficient, and more sustainable. With over 30 years of experience in semiconductor innovation, we bring that purpose to life across every part of the business—from breakthrough product development and customer success to how we show up for each other and the communities we serve.

The Opportunity

The Failure Analysis Engineer position is a highly hands-on role dedicated to performing in-depth analysis of semiconductor integrated circuits (ICs) failures. This position is primarily based in the Failure Analysis lab, with the majority of the work involving direct lab activity. The role focuses on identifying root causes for yield excursions, new technology development issues, and reliability failures. The successful candidate will utilize precision electrical characterization tools and physical analysis techniques to determine failure mechanism and assist in root cause analysis.

What You Will Do

• Electrical Characterization (80% of Role): Perform extensive manual probing and electrical fault isolation on wafers and packaged parts. Utilize Source Measure Units (SMUs), oscilloscopes, and curve tracers to characterize electrical signatures and pinpoint anomalies.

• Physical Analysis (20% of Role): Perform targeted physical deconstruction, including mechanical polishing/grinding for cross-sections and the use of wet chemical etching and decapsulation to correlate electrical findings with physical defects.

• Advance FA techniques: Utilize advanced failure analysis techniques such as optical microscopy, SEM/EDX, FIB, OBIRCH, PEM and IR microscopy.

• Yield & Tech Development Support: Conduct in-depth analysis on wafer-level issues to identify process-related yield issues. Work closely with the technology development team to analyze failures in next-generation silicon processes.

• Reliability Analysis: Analyze devices that have failed during stress testing (REL) to understand degradation mechanisms and long-term stability.

• Collaboration & Reporting: Document findings in detailed technical reports and collaborate with Process, Design, and Yield Enhancement (DYE) teams to drive corrective actions.

What You Will Need

• Bachelor's or Master’s degree in Electrical Engineering or Computer Engineering is required.

• Understanding of semiconductor device physics, IC fabrication processes, and packaging technologies.

• Excellent problem-solving skills and a methodical approach to root cause analysis.

• Ability to interpret complex electrical schematics and layouts.

• Strong written and verbal communication skills, with the ability to present technical information effectively.

• Ability to work independently and as part of a team in a fast-paced environment.

Preferred Qualifications:

• Familiarity with statistical analysis tools and methodologies for data interpretation.

• Experience with programming or scripting for automation of analysis tasks.

• Knowledge of reliability testing standards (e.g., AEC-Q100, JEDEC) and failure analysis techniques and equipment is a plus.

• Experience with Allegro's specific product lines (e.g., magnetic sensors, power management ICs, motor drivers) is a plus.
