It's fun to work in a company where people truly BELIEVE in what they're doing! We're committed to bringing passion and customer focus to the business.

If you like wild growth and working with happy, enthusiastic over-achievers, you'll enjoy your career with us!

Join a world leader and innovator in semiconductor and photonic device manufacturing as a Shift Process Engineer at our Caswell site.

The Shift Process Engineer provides hands‑on engineering support to semiconductor fabrication and backend manufacturing, ensuring safe, stable and efficient production. This is a shift‑based role (24x7 operation, 12‑hour shifts) rotating 2days, 2nights, 4days off structure. Working closely with Manufacturing, Process Engineering, Equipment Engineering, Product Engineering, Quality and R&D, the role supports process control, troubleshooting, production recovery, continuous improvement and new product introduction (NPI).

The role may support one or more of the following technology areas: Lithography & E‑Beam Lithography, Dry & Wet Etching, Thin Film Deposition, Metal Deposition and Backend Wafer Processing.

Key Responsibilities

• Provide shift-based process engineering support across semiconductor fabrication and backend manufacturing operations.
• Act as an engineering point of contact for Manufacturing, providing timely technical support for process, product and equipment-related issues.
• Monitor process and product performance using SPC, MES and other manufacturing data systems, responding appropriately to abnormal or out-of-control conditions.
• Investigate manufacturing excursions using structured problem‑solving and root‑cause‑analysis techniques, implementing appropriate containment, recovery and corrective actions.
• Maintain and improve production processes to enhance process capability, yield, quality, throughput, cycle time and cost.
• Support the development, qualification and introduction of new or modified manufacturing processes and products.
• Apply SPC, DOE, Six Sigma, Lean Manufacturing and statistical methodologies to process improvement activities.
• Identify recurring manufacturing issues and elevate significant or unresolved problems to the appropriate process owner or engineering team.
• Prepare and maintain technical documentation including operating procedures, engineering reports, process specifications and training materials.
• Ability to mentor Manufacturing personnel while ensuring established process controls, quality requirements and operating procedures are followed.
• Work safely to semiconductor cleanroom and manufacturing environments and comply with all site health, safety and environmental requirements.
