About The Position

We are looking for a Senior Process Engineer to join our Paper Mill Division. Reporting to the Senior Technical Strategies & Solutions Manager, this full-time, on-site role serves as the technical authority for the full fiber-to-reel process across three Ontario paper mills. This is a hands-on senior individual contributor position focused on improving throughput, stabilizing quality, reducing cost-per-ton, and translating multi-site strategic initiatives into measurable mill-floor results. The successful candidate will work on-site across the Ontario mill network, traveling between locations based on production priorities, trials, and operational needs. This role requires strong floor presence, technical depth, and the flexibility to support trials, startups, grade transitions, and significant production events, including extended or after-hours work when needed.

Requirements

Engineering degree in Chemical, Mechanical, Pulp & Paper, or a related discipline from a recognized university
8–12 years of process engineering experience in a continuous manufacturing environment, including at least 5 years in pulp and paper operations
Demonstrated experience owning process performance on a commercial paper machine; recycled linerboard or containerboard experience is considered a strong asset
Working knowledge of the full fiber-to-reel process, including stock prep, mill water balance, and the interface with aerobic and anaerobic effluent treatment systems
Hands-on experience with process control fundamentals, including loop tuning, PID configuration, DCS-based troubleshooting, and interpretation of historian or trend data
Proven ability to lead mill trials, vendor and OEM engagements, and improvement initiatives from scoping through implementation with minimal supervision
Strong analytical capability using historian platforms, DCS trends, Excel, Minitab, or similar statistical tools to drive process decisions
Eligibility for P.Eng. registration in Ontario, or a commitment to obtain registration within 12 months; P.Eng. in good standing is preferred
Valid driver’s license and willingness to travel daily between Ontario mill sites, with flexibility to support extended hours during trials, startups, and production events

Nice To Haves

Experience with OCC or recycled furnish, wet end chemistry, Six Sigma, or capital project commissioning is considered an asset

Responsibilities

Own process performance from stock prep to reel across all three Ontario mills
Lead network-level troubleshooting for runnability issues, sheet defects, breaks, and grade changes
Maintain mass, water, and energy balances across stock prep, wet end, and ETP operations, including upstream impacts on aerobic and anaerobic treatment
Optimize process control loops, including tuning, PID configuration, cascade and feed-forward strategies, and DCS performance
Lead root cause investigations into chronic losses and implement engineered countermeasures to prevent recurrence
Embed solutions through standard work, controls, and systems that sustain gains across shifts and grade changes
Standardize and audit process parameters, operating windows, and control setpoints across the three mills
Lead process workstreams for corporate-sponsored, multi-site initiatives across the Ontario network
Author and maintain SOPs, control narratives, and trial protocols for network use
Align best practices across mills where grade mix and equipment allow.
Provide technical coverage for site process engineers during vacancies, absences, or capability gaps
Design, execute, and report mill trials using DOE with defined success criteria, controls, and go/no-go decisions
Partner with Quality to protect sheet integrity and downstream customer performance during trials
Quantify trial results in OEE, cost-per-ton, and grade capability, and present recommendations in weekly leadership review
Support commissioning, startup ramp-up, and validation of capital projects against target performance
Use historian, lab, and DCS data to identify and prioritize high-ROI improvement opportunities
Build and maintain process KPI dashboards with the Senior Digital Engineer
Apply SPC and capability analysis to separate signal from noise before recommending changes
Lead all process work with a safety-first approach and apply MOC and HAZOP where required
Coordinate with Environmental on process changes affecting effluent quality, system loading, and treatment performance
