Manufacturing Applications Engineer
ArcelorMittal Dofasco – Process Automation Department
Permanent Position | Hamilton, ON

Background:

ArcelorMittal Dofasco operates a world-class computer-integrated manufacturing facility utilizing modern information technologies and industrial automation. The Process Automation Department is responsible for large-scale, high-impact manufacturing application systems that are integral to production—from raw materials to finished products. We continuously advance automation and digital capabilities to enable safe, reliable, and high-performing operations.

Who are we looking for?

We are seeking an experienced, outcomes-driven Manufacturing Applications Engineer to own and improve plant-critical manufacturing applications and Operational Technology (OT)-enabled information systems. This role is ideal for someone who can bridge operations and technology, translate production needs into practical solutions, and drive reliable execution through cross-functional teams and vendors.

The successful candidate’s position title (Sr. Analyst / Specialist / Sr. Specialist) will be based on qualifications and experience.

Key Responsibilities:

• Own the lifecycle of manufacturing applications and OT systems: requirements, delivery, sustainment, and continuous improvement.
• Partner with Operations, Maintenance, Quality, and Engineering to identify high-value enhancements, define scope, and prioritize work.
• Support system integration across OT platforms (automation interfaces, historians, databases, reporting/analytics, and application-to-application interfaces).
• Improve system reliability through disciplined incident/problem management, root-cause analysis, and prevention of repeat failures.
• Coordinate vendors and internal teams through implementation, testing, commissioning support, and stabilization.
• Maintain strong operational practices: change management, documentation, standards, backup/restore readiness, and cybersecurity alignment.
• Contribute to team capability building through knowledge sharing and mentoring.

Desired Skills & Experience:

• Bachelor’s degree in an Engineering discipline (Electrical, Mechanical, Chemical, Physics, Computer, or related).
• Demonstrated experience supporting or leading work in an industrial/manufacturing environment with OT systems and plant-critical applications.
• Strong troubleshooting skills: structured problem investigation, risk assessment, and practical mitigation.
• Ability to manage competing priorities and communicate clearly with technical and non-technical stakeholders.
• Technical familiarity with manufacturing/OT environments (e.g., industrial automation concepts, data collection, historians, databases, interfaces).
• A solid foundation in software development is needed to be effective in this role, although advanced development is not the primary focus (e.g., scripting, SQL, configuration, basic coding).

Work Environment:

• Office and industrial setting in production areas when necessary.

Work Expectations:

• Days, Monday–Friday with extended hours to cover project deadlines and peak workloads as required.
• Flexible start / end times
• Paid on-call rotation.
