What are the key skills and qualifications needed to thrive as a Process Simulation Engineer, and why are they important?

To thrive as a Process Simulation Engineer, you need a strong background in chemical or process engineering, proficiency in mathematical modeling, and typically a relevant engineering degree. Familiarity with simulation software such as Aspen Plus, HYSYS, or MATLAB, as well as knowledge of process control systems, is essential. Strong analytical thinking, problem-solving abilities, and effective communication skills help you interpret complex data and collaborate with multidisciplinary teams. These skills ensure accurate process optimization, improved system performance, and successful project outcomes in industrial environments.

What are some typical challenges a Process Simulation Engineer faces when integrating simulation models into existing operations?

A common challenge for Process Simulation Engineers is ensuring that simulation models accurately reflect real-world plant operations, which often involves dealing with incomplete or outdated process data. Collaboration with cross-functional teams, such as operations, process design, and IT, is crucial for gathering accurate information and validating models. Additionally, integrating simulation results into operational decision-making can require effective communication to bridge the gap between technical modeling and practical application. Successful engineers are adept at troubleshooting discrepancies and adapting models to evolving process requirements.

What are Process Simulation Engineers?

Process Simulation Engineers are professionals who use advanced computer modeling and simulation software to design, analyze, and optimize industrial processes, particularly in fields like chemical, oil and gas, pharmaceuticals, and manufacturing. They create virtual models of production systems to predict performance, troubleshoot issues, and propose improvements before implementation in the real world. Their work helps companies increase efficiency, reduce costs, ensure safety, and comply with environmental regulations.

What is the difference between Process Simulation Engineer vs Chemical Process Engineer?

AspectProcess Simulation EngineerChemical Process Engineer
CredentialsBachelor's or Master's in Chemical Engineering or related field; proficiency in simulation softwareBachelor's or Master's in Chemical Engineering; often includes process design experience
Work EnvironmentDesign labs, engineering firms, manufacturing plantsRefineries, chemical plants, R&D labs
Industry UsagePrimarily in process design, optimization, and simulationProcess design, plant operation, process improvement
Common Search/ComparisonYesYes

The Process Simulation Engineer focuses on creating and analyzing process models using simulation software to optimize chemical processes. In contrast, the Chemical Process Engineer is involved in designing, developing, and improving chemical manufacturing processes, often working directly on plant operations. Both roles require a strong background in chemical engineering and share overlapping skills, but their primary responsibilities and work environments differ slightly.

The Opportunity:
CACI is looking for an experienced Space Vehicle Modeling and Simulation Engineer to work with NASA's human-rated spacecraft systems in support of our Nation's space exploration initiative at NASA / Johnson Space Center in Houston, TX. Candidates should have great interest in spacecraft vehicles and systems, enjoy working with software, and most of all, possess a great passion to contribute to our Nation's exploration of space.
This work involves math model and simulation development, integration, verification and validation on Linux PC platforms using the Trick© Simulation Environment and Development Toolkit. Individual will execute large-scale simulation verification and validation tasks and develop math models and simulations in support of the Artemis program for NASA space vehicles lunar base, and lunar surface exploration. The ideal candidate has spacecraft domain experience in Guidance, Navigation, and Controls and a strong simulation development background.
The engineer in this role will support lunar base and lunar surface exploration simulation unit test development, code coverage analysis, verification, and validation for Class C simulation software. The engineer will identify and implement improvements to math models and simulation scenarios, analyze simulation data to evaluate system characteristics and performance, and support continual enhancements to the simulation architecture.
This position requires a self-motivated, capable person with strong verbal and written communication skills. In addition to outstanding technical expertise, the individual must be very people savvy with strong customer relationship skills, possess a positive team-player attitude, and be flexible and willing to take on new assignments and responsibilities as they arise. Finally, the most qualified candidate will be an articulate speaker able to communicate complex technical ideas in a convincing manner, must share our passion for our Nation's Space Program, and share in the excitement of developing the next human-rated space vehicles.
Responsibilities:
  • Develop space vehicle system and subsystem simulation math model requirements, verify model requirements, and validate the simulation and models.
  • Design and develop math models for spacecraft systems and subsystems including hardware and software.
  • Develop simulation scenarios to test nominal and off-nominal spacecraft operations.
  • Perform analysis on simulation data to investigate spacecraft system performance.
  • Present analysis results and their impact on spacecraft performance, vehicle design and mission design to customers.

Qualifications:
Required:
  • U.S. Citizen or Permanent Resident for access to USG Facilities.
  • B.S. in Aerospace or Computer Engineering, Computer Science, or related disciplines with experience in software development, including overall project design, programming, testing, verification, validation, and documentation.
