  • Monitor alarm system performance, support alarm management and rationalization activities, and help address nuisance, bad-actor, and standing alarms so operators can respond effectively to changing conditions.
  • Develop, maintain, and update documentation for control strategies, alarms, calculations, interfaces, standards, and procedures, including control narratives and related records in systems such as SAP.
  • Participate in process safety and Management of Change (MOC) activities, including process hazard analyses (PHAs), incident investigations, audits, and inspections, providing control system input and implementing assigned actions.
  • Use engineering tools, models, and analytics to test, validate, and report on control system performance against defined metrics and key performance indicators (KPIs), and share findings with cross-functional teams.

What You'll Bring - Required
  • Legally authorized to work in the job posting country
  • Bachelor's degree
  • 1 or more years of relevant working experience as a process, automation, or controls engineer or a similar engineering role in the refining, manufacturing, petrochemical, oil and gas or related industry

    • Climb ladders and stairs up to 200 feet in height
    • Enter confined spaces during turnarounds and equipment outages
    • Transport articles up to 50 pounds
    • Work around chemicals, including acids and bases
    • Work around hydrocarbons under high pressure and heat
    • Work outside in harsh weather conditions
    • Wear fire-retardant clothing and personal protective equipment (such as steel-toe shoes, and ear and eye protection)
  • Willing and able to obtain a Transportation Worker Identification Card (TWIC)

What Makes You Stand Out - Preferred
  • 3 or more years of combined experience in process engineering/design, process control, automation, and/or related controls engineering work in refining, petrochemical, manufacturing, or a related industry
  • Experience as a process or controls engineer supporting the use, design, installation, configuration, and commissioning of control systems in a refinery or chemical manufacturing environment
  • Experience with one or more refinery processes such as crude/vacuum distillation, reforming, hydrotreating, alkylation, fluid catalytic cracking, hydrocracking, or sulfur recovery
  • Knowledge and experience with process control techniques, including regulatory control, loop tuning, control logic development, alarm management, and advanced process control design
  • Experience with the Honeywell Experion distributed control system (DCS), SCADA interfaces to third-party PLCs and other devices, and Honeywell alarm management tools such as Dynamo
  • Experience leading or contributing to small and medium process control projects from design through startup, coordinating with cross-functional teams and vendors
