Altair Engineering has multiple job openings related to CFD solver development activities.  The primary responsibility of the positions is to improve the multiphase flow and compressible flow capabilities of the finite-element based CFD software, AcuSolve. This task includes algorithm development and validation to support simulation. These candidates will work very closely with a young team of software developers, in a vibrant work environment with excellent growth potential.

Built upon a rigorous scientific foundation, AcuSolve is a proven asset for companies looking to explore their designs. AcuSolve provides powerful fluid flow analysis capabilities without the difficulties associated with traditional CFD applications.

An industry leader since 1985, we have established our position by selecting the best and brightest talent, creating a world-class team of software developers, engineers, and design consultants that share a high level of technical education and in-depth knowledge of products and processes.


  • Primary responsibility of this position is to develop and implement algorithms in AcuSolve to simulate multiphase (miscible and immiscible) and compressible flow (transonic and supersonic) flows.
  • Collaborate with the solver team on other development activities.
  • Work with product managers in planning and executing long-term development activities.
  • Guide application engineers in preparing validation cases.
  • Provide third-level expertise and support for end-users.

Skills and Experience required:

  • Ph.D. or equivalent industrial experience.
  • Proven experience in independent research and development.
  • Large scale/well resolved immiscible multiphase flow simulation interface capturing (VOF, levelset, CLSVOF,…).
  • Small/sub-grid scale immiscible multiphase flow (Euler-Euler, Euler-Lagrangian, DEM).
  • In-depth knowledge of theory of transonic and supersonic flows with shocks, expansion waves, and contact discontinuities.
  • Experience in developing Navier-Stokes solver for high-speed compressible flows using finite-element or finite-volume method.
  • Finite element method.
  • Turbulent interactions in single phase and multiphase phase flows.
  • Heat transfer and phase change.
  • Experience programming in large code base.
  • Experience developing flow solvers from scratch.
  • Broad understanding of physics.
  • Broad understanding of numerical methods.
  • Excellent communication skills.
