Industry & Context.
reconcile model output against test data to drive model refinement and surface component-level insights
What They're Looking For.
Must Have
6+ years of experience in cycle performance analysis, thermodynamic systems modeling, or dynamic process simulation, fundamentals in thermodynamics, fluid mechanics, and heat transfer, applied to integrated multi-component systems, Demonstrated experience building dynamic simulation models of fluid/thermal systems in an industry-grade 1D system simulation platform, Working knowledge of integrated power loop equipment — heat exchanger sizing, compressor/pump curves, valve Cv, piping hydraulics — and how each shows up in dynamic response, Programming proficiency: Python for data reduction and one of MATLAB/Simulink, Modelica, or equivalent for modeling, ownership mentality and comfort driving rigorous analysis in a fast-paced startup environment
Nice to Have
Deep experience with industry dynamic simulation platforms (such as GT-SUITE, Modelica/Dymola, NPSS, Flownex, Simcenter Amesim, or equivalent) applied to turbomachinery, power cycles, or closed-loop thermal-fluid systems, Background in nuclear thermal-hydraulics with fast-dynamic single-phase modeling experience (RELAP, TRACE, MARS, ATHLET, GAMMA, or equivalent), particularly applied to gas-cooled or sCO₂ reactor concepts, Working knowledge of real-fluid EOS handling (REFPROP, CoolProp, Span-Wagner) and turbomachinery map interpolation near critical conditions, History of making and defending tool/methodology decisions in a constrained engineering environment, Experience with supercritical CO₂, closed Brayton cycles, high-pressure systems (100+ bar), or other high-density working fluids, Experience coupling plant models to control systems for HIL testing, controller validation, FMU export, or operator training simulators, Hands-on plant startup, commissioning, or field troubleshooting on first-of-a-kind or developmental systems, Background in rocketry, gas turbine, advanced reactors, or high-performance turbomachinery environments
What You'll Do.
reconcile model output against test data to drive model refinement and surface component-level insights
Own the architecture call on how our dynamic modeling stack should evolve over time — what platform
Build property tables
turbomachinery map handling
heat exchanger transient models
and combustor representations appropriate to the cycle and fidelity required
Develop simulation infrastructure — scripted scenario runs
validation cases — that makes the model usable by engineers beyond yourself
How You'll Work.
Team & Collaboration
Collaborate with combustion, turbomachinery, and heat exchanger engineers to integrate component data into system-level; collaborate with controls and software teams on closed-loop simulation and HIL planning
