Process Safety and Mechanical Integrity Engineer

Shape safer, smarter refining — one day at a time

Picture your day at Safety-Kleen (a Clean Harbors company) in East Chicago, IN. You start with a field walk, verifying that inspections on pressure vessels and storage tanks are on schedule. A contractor meets you at a pump skid — you review specs you authored, confirm scope, and prep the team for a safe installation. Mid-morning, you chair a Management of Change (MOC) review, ensuring risk assessments, training, and documentation are airtight before any modification touches the process. After lunch, you lead a Pre-Startup Safety Review (PSSR), then pivot to analyzing heat exchanger performance data to boost throughput and energy efficiency. You finish by updating P&IDs and closing out action items from a recent PHA. Safe, reliable, efficient — that’s your signature.

What you’ll drive

• Champion refinery safety and operational excellence across Operations, Maintenance, Health & Safety, and Compliance.
• Serve as a core resource for the Process Safety Management (PSM) program — facilitate PHAs, incident reviews, audits, and continuous improvement.
• Act as the site MOC coordinator and gatekeeper: ensure technical reviews, risk analyses, approvals, training, document updates, and tracking through closeout (including temporary changes).
• Lead PSSRs for projects and modifications; verify prerequisites, procedures, inspections, and training prior to startup.
• Own the Mechanical Integrity and Inspection program: planning, scheduling, documentation, and tracking for covered equipment and systems.
• Interpret inspection results with technical experts; recommend repairs/replacements; track deficiencies to resolution; communicate equipment risks and required actions to leadership.
• Keep process safety information current — process flow diagrams, P&IDs, equipment specs, and design data reflecting approved plant changes.
• Guide the annual capital plan with the Refinery General Manager — scope, estimates, business cases, and schedules.
• Deliver multiple small capital projects annually, and occasional larger efforts up to ~$1MM, from concept and engineering through procurement, installation, commissioning, and closeout.
• Coordinate permitting with Compliance and stakeholders; align plant activities with Operations, Shipping/Receiving, Maintenance, H&S, Compliance, management, and corporate engineering.
• Develop equipment specifications and contractor scopes; evaluate proposals; procure equipment/services per policy, regulations, standards, and budget.
• Partner with H&S, Compliance, Operations, and Maintenance to solve equipment and process issues — improving safety, environmental performance, reliability, and production.
• Support Maintenance on troubleshooting, failure analysis, repair planning, reliability upgrades, and planned outages (inspection scopes, priorities, technical requirements).
• Analyze process and equipment data to elevate throughput, quality, energy efficiency, and operating costs; implement best practices with internal/external technical groups.
• Author and revise operating and maintenance procedures and process instructions; support technical training for new equipment, process changes, and lessons learned.
• Be an active member of the Health & Safety Committee — inspections, hazard reviews, prevention initiatives, and corrective action follow-up.

What you bring

• Bachelor’s in Mechanical, Chemical, Petroleum, Industrial Engineering, or related field.
• 3+ years of engineering experience in a refinery, chemical processing, or comparable industrial environment (5+ preferred).
• Hands-on experience within a mature PSM environment (MOC, PHAs, PSSRs).
• Background in Mechanical Integrity programs: inspection scheduling, documentation, findings review, and corrective action tracking.
• Proven capital project management: scope, estimates, procurement, contractor coordination, installation, and startup.
• Working knowledge spanning process and mechanical engineering — instrumentation, piping, valves, pumps, pressure vessels, tanks, heat exchangers, materials, and controls.
• Mechanical aptitude for plant troubleshooting and practical problem solving.
• Proficiency reading P&IDs, PFDs, blueprints, equipment drawings, and technical specs.
• Ability to interpret process data, spot trends, and recommend improvements to safety, reliability, efficiency, and quality.
• Familiar with relevant engineering codes and inspection standards.
• Strong organization and follow-through across multiple projects and programs; diligent documentation.
• Influential communicator who can align cross-functional teams without direct authority.
• Microsoft Office proficiency; Microsoft Project (or similar) is a plus.
• Experience in waste industry, used oil re-refining, refinery, or chemical processing is an asset.
• Field capability in an industrial setting: lift up to 50 lbs, climb stairs/ladders, stoop, work at heights, bend, stand for long periods, and work in varying weather conditions, with or without reasonable accommodation.
• Willingness to provide off-hours technical support for outages, startups, and emergency callouts.
