• Collaborate closely with Process, Mechanical, Electrical, and Controls Engineering teams to ensure instrumentation is fully integrated into broader systems architecture.
• Partner with EHS teams to develop and implement validation and safety strategies, ensuring regulatory compliance and system robustness.
• Oversee the specification, sourcing, and implementation of instrumentation packages, coordinating with vendors and MP’s supply chain team to meet scope, budget, and schedule.
• Act as a mentor and technical leader to junior engineers—supporting knowledge transfer, design reviews, and professional development within the instrumentation team.
• Support or lead efforts to develop and maintain compliance with engineering codes, electrical standards, and hazardous area classifications.
• Champion a culture of technical excellence and continuous improvement within the engineering function.
• Other duties as assigned.

Basic Qualifications:

• Bachelor’s degree in Electrical Engineering, Electronics Engineering, or a related field (or equivalent experience).
• 7+ years of relevant experience in the design, specification, configuration, and validation of industrial instrumentation systems.
• Proven experience reviewing and developing detailed design documents, including P&IDs, loop drawings, I/O lists, and instrument index documentation.
• Minimum 3 years of experience developing or contributing to instrumentation standards and best practices.
• Familiarity with industrial communication protocols (Ethernet/IP, Profinet, Modbus TCP).
