We are looking for an experienced Refractory Engineer to join our Projects team at our Nashwauk, MN facility. The incumbent is responsible for overseeing the selection, installation, inspection, maintenance, and performance monitoring of refractory linings across high‑temperature equipment and process areas within the steel plant. These include the pellet plant, beneficiation plant, concentrator plant, and crushers. This is a key role focused on ensuring equipment reliability, process safety, and thermal efficiency through expert refractory management.

• Develop and implement preventive and predictive maintenance schedules for refractory‑lined equipment.
• Lead refractory shutdown activities, including relining and repair works in pelletizing kilns, in duration furnaces, rotary dryers, and hot gas ducts.
• Manage planning, procurement, and inventory control of refractory materials across plant operations.
• Conduct regular refractory inspections and thermal audits using techniques such as thermography and endoscopy.
• Identify wear patterns, hot spots, or potential failures and measures.
• Maintain detailed inspection reports and develop condition monitoring dashboards.
• Supervise refractory contractors during installation, shutdowns, and emergency repairs.
• Ensure quality control and adherence to technical specifications and safety protocols during all refractory‑related work.
• Enforce safety practices during refractory handling and installation in high‑temperature zones.
• Analyze refractory performance, material usage, and failure trends to drive cost reduction and efficiency.
• Recommend technical upgrades or changes in material specs for improved reliability.
• Support implementation of sustainable practices to reduce environmental impact.
• Ensure all refractory work complies with applicable OSHA, MSHA, and environmental regulations.
• Assist with budgeting and resource planning for refractory projects.

• 5 to 12 years of progressive experience in refractory engineering, high‑temperature systems, or industrial maintenance — ideally within the iron & steel, cement, mining, or heavy manufacturing industries.
• Proven track record in managing maintenance shutdowns, refractory installations, and equipment reliability programs in process‑intensive environments.
• In‑depth knowledge of refractory materials (acidic, basic, insulating, castables, etc.).
• Familiarity with refractory design for kilns, furnaces, dryers, including anchoring and thermal expansion considerations.
• Understanding of thermal processing in pelletizing and ore beneficiation plants.
• Proficiency with inspection techniques like thermography, borescope/endoscope inspections, and material testing.
• Strong leadership and contractor management capabilities.
• Excellent analytical and troubleshooting skills.
• Effective written and verbal communication for cross‑functional teamwork.
• Ability to handle shutdown pressure and lead time‑sensitive repair operations.

• Bachelor's Degree (or higher) in Materials Science & Engineering, Mechanical Engineering,…
