Job description

Hire Resolve is assisting petrochemical organizations in hiring experienced petrochemical professionals to support refinery, chemical, and downstream manufacturing operations across the United States. This is a multi-role opportunity spanning several functions within the sector—such as plant operations, process and project engineering, reliability and maintenance, EHS/PSM, quality, supply chain, and commercial/technical services. These openings are designed for mid- to senior-level talent and offer a clear pathway toward senior leadership roles, including superintendent, plant/area manager, engineering manager, and regional leadership positions.

Key Responsibilities
  • Lead and optimize safe, efficient plant operations across continuous and batch processes, utilities, and supporting units
  • Drive process improvements, debottlenecking, yield optimization, energy efficiency, and cost reduction initiatives
  • Support or lead capital projects from scope definition through execution, commissioning, and handover (FEL/front-end planning through start-up)
  • Develop and maintain technical documentation, procedures, and operating envelopes (P&IDs, SOPs, MOCs, PSM elements, etc.)
  • Strengthen reliability programs including preventive/predictive maintenance, RCA, turnaround planning, and asset integrity strategies
  • Ensure compliance with OSHA process safety management (PSM), EPA risk management expectations (where applicable), and site EHS programs
  • Implement risk assessments and safe work systems (PHA/HAZOP participation, JSA, LOTO, contractor safety oversight)
  • Manage cross-functional teams and stakeholders (operations, maintenance, engineering, labs, contractors, vendors) to deliver site goals
  • Monitor KPIs and performance dashboards for safety, production, quality, reliability, and budget adherence
  • Support audits and inspections; coordinate corrective actions and continuous improvement plans
  • Contribute to talent development through coaching, training plans, and succession planning within operations and technical teams

Requirements

  • Bachelor’s degree in Chemical Engineering, Mechanical Engineering, Electrical Engineering, Industrial Engineering, Chemistry, or a related technical discipline (advanced degree or relevant certifications are a plus)
  • Typically 7–15+ years of experience in petrochemical, refining, specialty chemicals, polymers, industrial gases, or adjacent process manufacturing environments
  • Working knowledge of core petrochemical processes and plant systems, with demonstrated exposure to one or more functional tracks (operations leadership, process engineering, reliability, maintenance, EHS/PSM, projects, quality, or commercial/technical support)
  • Familiarity with U.S. safety and compliance expectations (OSHA, PSM, LOTO, contractor safety; EPA and DOT awareness depending on role/site)
  • Competency with common engineering and maintenance systems (e.g., SAP/Maximo, PI System or similar historians, MOC/PSM tools, CMMS, basic data analysis in Excel)
  • Strong communication skills for plant-floor execution and cross-functional leadership; able to document, present, and influence stakeholders
  • Ability to work onsite in an industrial environment; some roles may require shift coverage, on-call rotation, or travel depending on site needs

Benefits

  • Health Care Plan (Medical, Dental & Vision)
  • Retirement Plan (401k, IRA)
  • Life Insurance (Basic, Voluntary & AD&D)
  • Paid Time Off (Vacation, Sick & Public Holidays)
  • Family Leave (Maternity, Paternity)
  • Training & Development
