About the role

Process Safety Management (PSM) Engineer to build, administer, and continuously improve Mariana Minerals' process safety and major hazard risk management program across labs, pilot operations, process development, scale-up projects, and future facilities.

Responsibilities

  • Administer PSM and major hazard risk management workflows, including risk study planning, pre-work, facilitation, documentation, action tracking, and closeout verification and assist in development or improvement of processes.
  • Lead or support PHAs, HAZOPs, HAZIDs, LOPAs, what-if/checklist studies, bowties, formal risk assessments, and other structured reviews for lab, pilot, project, and operating systems and assist in the development of these tools where needed.
  • Support Management of Change and Pre-Startup Safety Review processes by reviewing technical changes, startup readiness, critical safeguards, training needs, procedures, and open action status.
  • Review PFDs, P&IDs, equipment specifications, operating envelopes, control narratives, layouts, chemical inventories, and utility interfaces to identify process safety and facility design implications.
  • Provide practical engineering input on life safety, fire protection, hazardous materials, ventilation, detection/alarming, emergency shutdown, pressure relief, containment, and occupancy or hazard classification questions.
  • Partner with internal SMEs, external engineers, insurers, and AHJs to clarify applicable code requirements and translate them into actionable design or operational requirements.
  • Develop and maintain process safety information, hazard registers, safeguard/IPL libraries, action trackers, PSM procedures, risk assessment templates, decision logs, and program metrics.
  • Evaluate safeguards and risk reduction actions using hierarchy of controls, independent protection layer concepts, reliability assumptions, field verification, and practical implementation constraints.
  • Support incident investigations, root cause analysis, corrective action development, lessons learned, and verification that systemic risk controls are implemented.
  • Help embed process safety expectations into project planning, commissioning, operating procedures, training, contractor scopes, field execution, and routine operations.
  • Support broader Health & Safety initiatives as needed, including HazCom, contractor safety, emergency response planning, field audits, safety observations, training, and procedure development.

Qualifications

  • B.S. or higher in Chemical Engineering, Mechanical Engineering, Mining Engineering, Metallurgy, Fire Protection Engineering, Safety Engineering, or a related technical discipline.
  • 5+ years of relevant experience in process safety, process engineering, plant design, operations, commissioning, EHS, or risk management in minerals, mining/metallurgy, chemicals, specialty materials, oil & gas, manufacturing, pilot plants, or lab-to-commercial scale-up environments.
  • Hands-on experience supporting or facilitating PHAs, HAZOPs, HAZIDs, LOPAs, MOC, PSSR, incident investigations, formal risk assessments, or similar structured risk management processes.
  • Ability to read and interpret PFDs, P&IDs, layouts, equipment data sheets, operating procedures, control narratives, chemical inventories, and safety-critical design information.
  • Working knowledge of process safety and facility safety requirements such as OSHA PSM, EPA RMP, IFC/IBC concepts, NFPA standards, pressure systems, hazardous materials, electrical safety, fire protection, ventilation, and emergency planning.
  • Strong technical writing, meeting facilitation, action tracking, data organization, and communication skills.
  • Ability to challenge assumptions constructively, document decisions clearly, and translate risk assessment outputs into practical controls, design inputs, procedures, and field actions.
  • Comfortable working in fast-paced, ambiguous environments, wearing multiple hats, and balancing program administration with field-facing technical support.
  • Professional certifications or specialized training such as PE, CSP, CCPSC, CFPS, HAZOP/LOPA facilitation training, or equivalent process safety credentials are a plus.
  • Experience with pilot plants, lab-scale hazards, scale-up projects, hazardous materials permitting, fire/life safety coordination, commissioning, or operational readiness is a plus.
