  • Ten or more years of progressively responsible process engineering experience for Senior-level consideration, with substantial experience in oil and gas midstream facility design.
  • Demonstrated ability to independently complete process calculations, simulations, equipment sizing, hydraulic evaluations, and engineering deliverables.
  • Experience coordinating with other engineering disciplines and communicating directly with clients and operations personnel.
  • Strong knowledge of process engineering fundamentals, including thermodynamics, fluid mechanics, heat transfer, mass transfer, phase behavior, and process control.
  • Demonstrated experience with oil, gas, water, and multiphase separation; oil treating and stabilization; gas dehydration; amine treating; refrigeration; hydrocarbon dew-point control; compression and pumping systems; pressure relief and flare systems; and facility utility systems.
