• Own and administer the site and regional SIS Functional Safety Management System, including procedures for proof testing, bypass management, overrides, demand reporting, and documentation control
  
  
• Lead and/or facilitate hazard and risk studies (PHA/HAZOP, LOPA, What if) to identify Safety Instrumented Functions and assign/confirm SIL targets; ensure alignment between initiating events, safeguards, and required risk reduction
  
  
• Develop and maintain SIS Safety Requirements Specifications (SRS), Cause & Effect matrices, logic narratives, and setpoint documentation for SIFs (ESD, BMS, Fire & Gas, critical interlocks, and trip functions)
  
  
• Perform or oversee SIL verification calculations (PFDavg / PFH, proof test intervals, common cause, hardware fault tolerance) and document assumptions, failure data, and test coverage; recommend redesigns where targets are not met
  
  
• Plan and coordinate Functional Safety Assessments/Audits (FSA stages as applicable) for new projects and for existing SIS; track findings to closure via MOC / corrective action processes
  
  
• Maintain a functional safety competence and training approach for engineers, technicians, and contractors who design, maintain, or test SIS
  
  

• Define and continuously improve SIS and critical instrumentation maintenance strategies, including proof test procedures, calibration standards, and test frequency optimization based on lifecycle reliability and risk
  
  
• Ensure all SIS assets (logic solvers, I/O, networks, final elements, sensors) are accurately registered in the CMMS with correct hierarchy, attributes, spares, and preventive maintenance/work instructions
  
  
• Monitor SIS performance (spurious trips, demand rates, bypass frequency, proof test compliance, instrument bad-actor lists) and report against established KPIs; drive targeted improvement plans
  
  
• Lead root cause investigations for SIS demands, nuisance trips, and instrument failures; implement corrective and preventive actions and update safety requirements specification/proof tests where required
  
  
• Partner with Operations, Maintenance, EHS/Process Safety, and IT to ensure SIS cybersecurity and change control practices support functional safety and availability
  
  

• Provide SIS and critical instrumentation leadership for capital projects from FEL through commissioning, ensuring SIS scope is clearly defined, budgeted, and delivered to functional safety requirements
  
  
• Review and approve contractor deliverables including ISA datasheets, instrument index, loop drawings, wiring diagrams, P&IDs, logic diagrams, control narratives, shutdown keying philosophy, and commissioning/validation procedures
  
  
• Ensure SIS design is consistent with applicable standards and good engineering practice (IEC 61511/ISA 84, IEC 61508 concepts, IEC 62443 where applicable, NFPA/NEC for electrical installations, hazardous area requirements)
  
  
• Drive standardization and obsolescence management for SIS platforms and safety rated devices; develop roadmaps for migration, spares, lifecycle support, and test strategy continuity
  
  
• Lead or support field commissioning, SIS validation, and functional testing; ensure comprehensive turnover packages (as-builts, SRS, proof tests, bypass lists, O&M, training, CMMS upload confirmation) are complete at handover
  
  

• Serve as the subject matter expert for SIS/functional safety, providing technical guidance to engineers, technicians, consultants, and EPC partners; review engineering changes for functional safety impact
  
  
• Develop and maintain contingency plans and short term operating procedures for abnormal SIS conditions (failed components, bypassed SIFs, partial functionality, communications failure) to preserve safety while restoring full protection
  
  
• Maintain disciplined Management of Change (MOC) for SIS including setpoint changes, bypass approvals, configuration management, and periodic backups/restore tests for safety PLCs and associated infrastructure
  
  
• Mentor and develop team members; contribute to standards, training, and continuous improvement across the Electrical Systems organization
  
  

• Bachelor's degree (or higher) in Electrical Engineering/ Instrumentation and Control Engineering
  
  
• 7+ years of experience in industrial instrumentation and control systems with significant responsibility for SIS/functional safety in operating facilities
  
  
• Demonstrated experience leading functional safety lifecycle activities: SRS development, SIL verification, proof test development/execution governance, MOC, and incident investigations
  
  
• Hands on knowledge of SIS platforms and architectures (safety PLCs/logic solvers, safety I/O, networks, final elements, and sensor technologies) and integration with DCS/PLC environments
  
  
• Experience supporting capital projects (scope, schedule, cost, technical risk) and leading commissioning/validation/turnover
  
  
• Working knowledge of IEC 61511 / ISA 84 functional safety requirements and the practical application of SIL concepts in design and maintenance
  
  
• Ability to interpret and develop P&IDs, control narratives, Cause & Effect matrices, loop sheets, logic diagrams, and wiring schematics
  
  
• Familiarity with hazardous area classifications (Class/Division and/or Zone), IP/NEMA enclosure ratings, and field installation practices
  
  
• Strong analytical and troubleshooting capability for instrument malfunctions, control/safety logic behaviors, and field device performance
  
  
• Ability to travel to manufacturing facilities as needed (approximately 35%)
  
  

• Professional Engineer (P.E. / P.Eng) designation
  
  
• Functional Safety certification (e.g., TUV Functional Safety Engineer/Professional or equivalent)
  
  
• Project Management Professional (PMP) or demonstrated project leadership experience
