Contract Position | Entry-Level Chemical Engineers Encouraged to Apply!

Schedule: 24/5 or 24/7 schedules. Shift work will be required periodically and specific schedules will be established based on project assignments.

About the Opportunity

TriStarr Talent is looking for hands-on Chemical or Process Engineers to support ongoing projects. This role blends engineering analysis, plant operations, troubleshooting, equipment installation, and process improvement.

It’s a strong opportunity for an early-career engineer who enjoys being in the field, working alongside operators, and seeing how engineering decisions perform in a real operating environment—not just on a spreadsheet.

What You’ll Do

  • Support engineering activities across multiple ongoing projects.
  • Operate chemical pilot plants as part of a collaborative shift team.
  • Work closely with operators to collect process data and produce hydrocarbon and chemical products.
  • Compile and analyze operating data, prepare mass balances, and generate technical reports.
  • Monitor pilot plant performance and troubleshoot process or equipment issues.
  • Assist with equipment installation, maintenance, turnaround activities, and unit cleanup.
  • Prepare samples and support testing and analysis.
  • Help develop operating procedures, safety documentation, and work instructions.
  • Work with pumps, heat tracing, drum heaters, high-temperature oils, piping systems, and chemicals.
  • Support or supervise pilot plant operations based on project needs and experience.
  • Perform practical engineering calculations, including:
  • Pressure-drop calculations
  • Pipe sizing and velocity calculations
  • Conductive and convective heat-transfer estimates
  • Particle-transport calculations
  • Support process-control activities and implement chemical processes using various control strategies.
  • Assist with pilot plant design, process-system development, and mechanical design work.
  • Use Excel, Word, and Visio to organize data, document processes, and communicate results.

What We’re Looking For

  • Bachelor’s degree in Chemical Engineering REQUIRED.
  • No experience required; two years preferred.
  • Strong working knowledge of Microsoft Excel and Word.
  • Experience with Visio, SolidWorks, AutoCAD, or other CAD software is a plus.
  • Ability to perform thermodynamic and process calculations.
  • Mechanical aptitude and an interest in building, operating, and troubleshooting process systems.
  • Ability to manage multiple priorities in a fast-paced operating environment.
  • Strong technical writing and communication skills.
  • Willingness and ability to work rotating or nontraditional shifts.
  • Valid driver’s license.
  • Local candidates are preferred.

Work Environment and Physical Requirements

Candidates must be able to:

  • Stand and walk for extended periods.
  • Climb stairs and ladders.
  • Work outdoors in varying weather conditions.
  • Travel between work areas located across a 1,200-acre site, which may include walking between nearby locations.
  • Occasionally lift up to 50 pounds with assistance, representing approximately 15% or less of the role.
  • Wear steel-toed safety footwear and other required personal protective equipment.
