Principal Engineer, Process Development Engineering

About the role

Analog Devices Limerick is hiring a Principal Engineer, Process Development Engineering, a senior individual contributor role at P5 level. It provides technical leadership 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 also shows growth toward P6 Expert expectations.

Key responsibilities

• Act as a recognised technical authority for manufacturing engineering and process integration, setting direction for complex improvement programmes and influencing site-level technical priorities for yield, quality, cycle time, reliability and capacity.
• Lead the integration, optimisation and control of complex semiconductor manufacturing processes so that process modules, unit devices, E-test and probe outcomes are robust, scalable and manufacturable.
• Serve as the primary technical expert for deposition processes, equipment capability, process controls and improvement priorities, covering issue resolution, process stability, risk management and long-term capability.
• Identify major contributors to yield loss, variation, scrap, rework and cost, and develop data-led improvement strategies with process, product, equipment, quality and operations teams.
• Lead structured investigations of high-impact manufacturing issues using root cause 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 identify trends, 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.
• Willingness to travel about 10% of the time; shift type is 1st shift/days.

Required skills

• Deep expertise in semiconductor manufacturing, process integration and equipment/process capability.
• Structured problem solving, statistical analysis, DOE, failure analysis and root cause investigation.
• 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.
