About the Job

Requirements

  • A Bac+5 qualification (Master’s or engineering diploma) in fluid mechanics, physics, applied mathematics, or scientific computing is required; a PhD is a significant asset.
  • At least 3 years of experience in multiphysics numerical simulation in an industrial context, applied research laboratory, or engineering office is required.
  • Practical proficiency in ANSYS Fluent (UDF, meshing, and post-processing) and/or COMSOL Multiphysics (coupled modules, LiveLink, and API) is required.
  • Experience customizing and scripting these tools using Python, C/C++, macros, and interfaces to external codes is required.
  • Knowledge of coupled multiphysics, including compressible flows, heat transfer, radiation, and electromagnetism, is required.
  • Ability to work independently on scientifically and technically demanding topics is required.

Responsibilities

  • Investigate and establish a coupling methodology between the internal code and commercial simulation platforms such as ANSYS Fluent and COMSOL Multiphysics to extend modeling capabilities to 3D configurations, including exhaust calculations, singular current regimes, and complex circuit-breaker geometries.
  • Identify and resolve technical obstacles in the existing MC3Xms/ANSYS Fluent coupling by analyzing current physical and numerical limitations, including data transfer, consistency of boundary conditions, coupled time-step management, and multiphysics convergence.
  • Implement coupling interfaces through APIs and customization environments of commercial tools, including ANSYS Fluent UDF/UDS, COMSOL LiveLink or Java API, and Python/C++ scripting to orchestrate exchanges between codes.
  • Physically validate developed methodologies by comparing simulation results with available experimental data and identifying domains of validity.
  • Document methodologies and support, train, and assist project-team users who perform simulations.
  • Manage the full numerical simulation generation chain, including software, domain-specific implementation, and the high-performance computing infrastructure required for the calculations.
  • Monitor commercial simulation tools such as ANSYS Fluent, COMSOL, and OpenFOAM for high-voltage plasma and arc applications, including new features, magnetohydrodynamics modules, radiation solvers, and co-simulation capabilities; establish and manage collaborations with simulation software vendors when needed.
  • Perform test or product-development calculations as needed to compare the physical behavior of commercial simulation tools with internal tools.
  • Contribute to team technical reporting through summary notes, steering committee presentations, and interaction with product development teams.

Desired Qualifications

  • Experience with thermal plasma or electrical arc physics, including magnetohydrodynamics, radiation, and species transport.
  • Knowledge of code-coupling topics, including solver data exchange, co-simulation, and coupling APIs.
  • Experience developing with Git in a multi-contributor environment.
  • Experience experimentally validating simulations by comparing tests and calculations.

About the Company

GE Vernova

Builds equipment and software for electric power

GE Vernova makes equipment and software that generate and manage electricity for utilities, power producers, and industrial customers. Its Power, Wind, and Electrification businesses span gas turbines, wind generation, and the systems that move electricity across grids. The company supplies generators, grid equipment, and controls, while its software coordinates network operations and integrates changing sources of power. Customers buy equipment and enter service agreements for maintenance, upgrades, and technical support over its operating life, alongside purchases of software and related services. GE Vernova became an independent company in 2024 after separating from GE and is headquartered in Cambridge, Massachusetts.
