Principal Engineer, Process Development Engineering

About the role

Analog Devices Limerick is hiring a Principal Engineer, Process Development Engineering (P5 level). This is a senior individual contributor role leading technical work across semiconductor manufacturing process integration, process enhancement, yield improvement and manufacturing efficiency, with specific accountability as Subject Matter Expert for the Deposition Work Centre. The role shows growth toward P6 Expert expectations.

Key responsibilities

• Act as a technical authority for manufacturing engineering and process integration, setting direction for improvement programmes and influencing site-level priorities for yield, quality, cycle time, reliability and capacity.
• Lead integration, optimization and control of complex semiconductor processes so that process modules, unit devices, E-test and probe outcomes are robust and scalable.
• Serve as the primary expert for deposition processes, equipment capability, process controls and improvement priorities, covering issue resolution, stability, risk management and capability development.
• Identify major contributors to yield loss, variation, scrap and rework, and develop data-led improvement strategies with process, product, equipment, quality and operations teams.
• Lead root cause investigations of high-impact manufacturing issues using structured analysis, statistical methods and technical judgement.
• Partner with R&D, process development, product engineering and operations to turn new technologies, materials and process flows into stable production capability.
• Use data analysis, statistical process control, design of experiments and modelling to predict process risk and enable proactive decisions.
• Influence multi-disciplinary teams across manufacturing, equipment engineering, product engineering, quality, planning and operations, and communicate complex technical topics clearly.
• Establish and sustain technical standards, documentation, control strategies and lessons learned, and mentor engineers and technicians.

Required profile

• Bachelor's degree in Electronics, Mechanical Engineering, Manufacturing Engineering, Materials Science, Physics or a related discipline, or equivalent experience.
• Typically 10+ years of progressive experience in semiconductor manufacturing, manufacturing engineering, process integration, equipment engineering or a related high-volume advanced manufacturing environment; fewer years may be considered with a relevant master's or doctorate.
• Track record of technical leadership and measurable improvements in yield, quality, cost, reliability or efficiency.
• Experience applying structured problem-solving and data-led improvement methods.

Required skills

• Deep expertise in semiconductor manufacturing, process integration and equipment/process capability.
• Root cause analysis, statistical analysis, DOE and failure analysis.
• Advanced analytics using manufacturing, yield, metrology, probe, reliability and equipment data.
• Strong cross-functional influence and clear communication to senior stakeholders.
• Quality, compliance and risk mindset, including change management and specification adherence.

The role involves travel about 10% of the time and works on the first shift, days. Export licensing review may be required for applicants who are not US citizens or permanent residents.
