Engineer Principal Pulp

Where you will work

Lewiston is Clearwater Paper’s original manufacturing facility and home to nearly 700 dedicated team members who power our site. Together, we make paperboard used in products across the United States, including food packaging, plates, cups and more. Home to the first mill that produced poster board from wood waste, the site currently operates two paper machines, two extruders, two power boilers and two recovery boilers.

Located where the Snake and Clearwater rivers meet on the Idaho-Washington border, Lewiston offers an active outdoor lifecycle with easy access to fishing, boating, hiking and camping. The region’s milder climate means more rain than snow in the winter and long, sunny days in the summer.

Living here means you’ll be close to Lewis-Clark State College, University of Idaho, Washington State University, and Walla Walla Community College, as well as strong local K–12 school districts

What you will do

The Principal Engineer serves as the senior technical authority for pulp mill operations, providing leadership and subject matter expertise across all pulp production systems including chip and sawdust fiberline, recaust, bleaching, ClO2 generation, and process support systems. This role partners closely with mill leadership, operations, maintenance, and reliability teams to establish and execute a comprehensive technical strategy focused on safety, process stability, cost optimization, asset reliability, and product quality.

The Principal Engineer leads the development and deployment of long-term reliability and process improvement initiatives, integrating process engineering support, quality systems, predictive maintenance, and operating discipline to improve mill productivity and reduce variability. As a key technical leader within the mill, this role drives both short- and long-term operational improvements, supports outage planning and execution, resolves complex process challenges, and ensures alignment between engineering standards and day-to-day mill performance.

In addition, the Principal Engineer plays a critical role in developing technical capability within the organization by mentoring engineers and operations leaders, strengthening troubleshooting rigor, and embedding data-driven decision-making across pulp mill operations. This position ensures that capital investments, environmental compliance efforts, and safety initiatives are technically sound and fully integrated into sustainable operating practices.

Technical and Operational Consultation 

• Serve as the senior technical authority for pulp mill operations, leading structured problem-solving efforts to identify and eliminate process variability, reliability losses, safety risks, and cost drivers using FMEA, Root Cause Analysis, VAVE, and data-driven methodologies.
• Lead the development and execution of pulp mill asset reliability and process safety strategies, integrating risk-based maintenance practices, capital prioritization, and operational discipline to protect production continuity and environmental compliance.
• Identify, evaluate, and advance process optimization and debottlenecking initiatives across fiberline, bleaching, and supporting systems; develop and execute multi-year technical roadmaps aligned with mill performance objectives.
• Act as the primary technical liaison to external engineering partners, OEMs, and service providers, ensuring solutions are technically sound, operationally practical, and delivered safely, on schedule, and within approved budgets.

Continuous Improvement

• Champion a culture of continuous improvement within pulp mill operations by regularly evaluating and refining maintenance strategies, critical spare parts programs, and vendor performance to enhance asset reliability and reduce total cost of ownership.
• Drive performance improvements through the development of engineering standards, process optimization initiatives, and equipment design enhancements, with emphasis on fiber yield, chemical efficiency, energy reduction, and environmental performance.
• Strengthen process control and quality systems by standardizing operating procedures, technical documentation, and troubleshooting protocols to ensure consistent pulp quality and predictable mill performance.
• Collaborate with commercial and product teams to provide technical insight into asset capabilities, process limitations, and innovation opportunities aligned with market and customer requirements.
• Capture and institutionalize best practices across pulp mill systems to ensure long-term sustainment of improvements and consistent application of technical standards.
• Partner with procurement and manufacturing leadership to evaluate and manage chemical programs and technical service agreements, ensuring measurable operational value, performance accountability, and cost competitiveness.

Engineering and Production Capability Building 

• Develop and sustain engineering and operational capability by mentoring technical staff, strengthening structured troubleshooting practices, and promoting data-driven decision-making across pulp mill operations.
• Lead the development and sustainment of qualification standards and technical competency frameworks for critical pulp production assets, ensuring depth of process understanding and effective knowledge transfer.
• Build long-term technical bench strength by formalizing best practice sharing, lessons learned, and continuous learning mechanisms within the pulp mill organization.

Key Competencies & Attributes

• Deep technical expertise in pulp mill operations, including fiberline chemistry, delignification, bleaching, process control, and recaust, with the ability to diagnose and resolve complex process challenges.
• Strong analytical capability with demonstrated experience using process data, operating metrics, and financial indicators to improve yield, reduce chemical and energy consumption, and enhance overall asset performance.
• Proven ability to identify operational and process risks, communicate technical impacts clearly, and lead development and execution of sustainable countermeasures.
• Demonstrated balance of strategic thinking and hands-on engagement; comfortable working in the field to understand process realities while developing long-term technical direction.
• Experience driving asset reliability and process stability through structured problem solving, risk-based maintenance strategies, and disciplined operating standards.
• Ability to influence across operations, maintenance, engineering, environmental, and commercial functions within a collaborative manufacturing environment.
• Confidence operating in complex and dynamic production settings, bringing clarity and structure to ambiguity and aligning teams toward measurable performance outcomes.
• Strong communicator capable of translating complex technical concepts into actionable plans for operators, leadership teams, and executive stakeholders.
• Demonstrated leadership in strengthening technical capability, elevating engineering standards, and embedding a culture of accountability and continuous improvement.
• High degree of autonomy, ownership, and accountability while maintaining alignment with mill leadership and broader business objectives.
