Foundry Operations Engineer (Resident)

About the role

The Resident Fab Engineer serves as the primary technical liaison between Allegro MicroSystems and its key wafer fabrication partner sites. This role requires a deep understanding of semiconductor processes and strong communication skills.

Responsibilities

• On-Site Technical Liaison: Serve as the primary point of contact between Allegro’s internal Quality/Product Engineering teams and the foundry’s process engineers.

• Yield & Quality Improvement: Monitor daily line health and wafer sort yields. Lead root-cause analysis for any yield excursions or process deviations using statistical process control (SPC) data.

• Process Monitoring & Control: Audit foundry process flows for Allegro-specific technologies (BCD, High Voltage, TMR). Ensure adherence to agreed-upon Process Control Plans (PCP) and Quality Agreements.

• New Product Introduction (NPI): Support the seamless transfer of new products from development into high-volume manufacturing. Coordinate the fabrication of engineering samples and "hot lots."

• Excursion Management: In the event of a manufacturing issue, lead the task force to identify the source of the problem, contain affected material, and implement corrective actions (8D reports).

• Continuous Improvement: Identify opportunities for cycle-time reduction, cost-saving process tweaks, and yield optimization without compromising device performance or reliability.

Requirements

• B.S. or M.S. in Electrical Engineering, Chemical Engineering, Materials Science, or Physics.
• 5-10 years of hands-on experience in a semiconductor wafer fab environment (Process Engineering, Yield Engineering, or Integration).
• Deep understanding of BCD (Bipolar-CMOS-DMOS) or Analog/Mixed-Signal process flows.
• Proficiency in statistical analysis software (e.g., JMP, Minitab, or Spotfire).
• Familiarity with failure analysis techniques (SEM, EDX, FIB).
• Exceptional ability to communicate complex technical issues to both internal executives and external foundry partners.
• "Resident" mentality—you are comfortable working autonomously at a partner site while remaining deeply connected to Allegro’s corporate goals and values.
