KeyLogic Systems Inc. has an exciting opportunity for an entry to mid-level process modeling and optimization engineer. KeyLogic is the prime contractor supporting the National Energy Technology Laboratory under the Mission Execution and Strategic Analysis (MESA) site-support contract. This position is intended to support the Process Systems Engineering Research (PSER) team under the Systems Engineering Analysis (SEA) Directorate of NETL. The employee will work on projects within the PSER program, specifically supporting the Institute for the Design of Advanced Energy Systems (IDAES) (), which is building and applying a next generation modeling and optimization platform to accelerate development of advanced energy systems. Primary responsibilities will include developing rigorous models of energy systems, mathematical optimization, and/or statistical analysis of lab-scale, pilot-scale, or commercial-scale process data while fulfilling the following general functions:

• Conduct exploratory and applied analyses in the areas of simulation, modeling and optimization, scientific computing, and the science of flowing materials, including multi-phase and chemically reactive flows.
• Investigate theoretical and fundamental phenomena as necessary to support PSER needs and develop new concepts,
• Provide technical expertise in the areas of virtual demonstration, process systems engineering and optimization.

Position Requirements:

• U.S. Citizenship or Legal Permanent Resident (Green Card Holder) is preferred
• Entry- to Mid-level MS/PhD in Chemical/Mechanical/Computer science Engineer with 0 - 10 years of experience in the process modeling of advanced energy systems.

The ideal candidate will have experience in one or more of the following areas:

• Development and utilization of rigorous steady-state and dynamic process models, including developing submodels for physical properties, thermodynamics and kinetics, utilizing at least one of the following classes of modeling platforms:

• Open source algebraic modeling languages such as Pyomo, Julia, CasADi, GAMS, AIMMS, AMPL, and/or MODELICA.

• Commercial process modeling tools such as gPROMS, Aspen Plus, Aspen Economic Analyzer, Aspen Dynamics, and Aspen Custom Modeler.

• Expertise in modeling complex energy system processes including:

• Process design (including cost estimation), synthesis, and integration (including heat/mass integration)
• Process modeling and simulation (both dynamic and steady-state)
• Process optimization and intensification
• Uncertainty quantification (including Bayesian approaches)
• Initializing and solving large scale optimization problems

• Familiarity with the development of reduced order models (ROM) to facilitate multi-scale simulations
• Use of trust regions methodologies for optimization

• Scale-bridging
• Modeling of energy systems
• Collaborating with experimentalists or process/equipment designers to develop and validate models
• Scientific and high-performance computing
