Join us in building Careers and shaping Experiences Beyond the Box”
At Atlantic Packaging, every box tells a story and yours begins here. As a proudly Canadian-owned company with over 80 years of excellence in the corrugated packaging industry with operations within North America (Ontario, Quebec and United States), we’re committed to sustainability, customer excellence and community impact. Since 1945, we’ve supported local jobs and built a legacy of trust with our clients and team members. 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.
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
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
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
Support commissioning, startup ramp-up, and validation of capital projects against target performance
Data-Driven 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
Safety & Environmental Stewardship

Coordinate with Environmental on process changes affecting effluent quality, system loading, and treatment performance
Strong knowledge of fiber-to-reel operations, troubleshooting, water balance, stock prep chemistry, ETP systems, and DCS controls
Uses structured root cause analysis, backs decisions with data, and builds lasting solutions
Independent Mindset & Project Leadership: Leads projects end-to-end, works independently, and turns strategy into mill-floor results
Vendor & OEM Leadership: Manages suppliers and OEMs as a technical lead and challenges proposals on merit and performance
Works across technical, operations, and maintenance teams to align priorities and deliver solutions
Communicates clearly on the mill floor and in leadership reviews, turning analysis into action
You bring strong technical depth, sound judgment, and the ability to lead improvement initiatives independently while partnering effectively with operations, quality, maintenance, vendors, and cross-functional technical teams.
