Be the Next Game Changer

PowerFLOW - Senior Software Engineer

United States, MA, Waltham

Imagine new horizons...


At Dassault Systèmes, we empower our employees and support their passion to change the world and build the future. Let’s design new horizons together with the power of 3DEXPERIENCE virtual universes!


What will your role be?


Design, develop and continuously improve software in order to provide World Class Apps, Services and Technologies delivering experiences & value to end-users.


Help develop cutting-edge PowerFLOW fluid simulation and design optimization software products that are used worldwide in industries such as ground transportation, aerospace and motorsports.


The challenges ahead…


Our team is responsible for the development of a GUI-based PowerFLOW simulation preparation tool, including 3D graphics display, which allows engineers to import geometry from their CAD models, prescribe simulation behavior, and then explore/review their model before running our Lattice Boltzmann-based fluid flow solver.


Your responsibilities will include adding new features, enhancing internal object-oriented frameworks (C++) for improved performance and maintainability, and accelerating our migration to the Dassault Systèmes 3DEXPERIENCE cloud-based, collaborative environment.


You will tackle interesting software engineering problems, writing code that is maintainable, extensible and robust. Usability and performance will be priorities, since we strive to make the complexity and large data sets inherent in fluid simulations manageable by way of intuitive controls and straightforward workflows.


For most projects, you will work independently, with opportunities to make your own design decisions.  However, you must also be a good collaborator who can work closely with other software teams working on the Dassault Systèmes 3DEXPERIENCE platform, as well as with various domain experts (physics, computational geometry, aerodynamics, thermal, aeroacoustics, etc.) to design and implement new product features, which satisfy customer requirements.

Your key success factors?


  • Solid C++ programming skills, including familiarity with STL, as well as modern (C++ 11+) features
  • Solid grounding in computer science theory
  • MS in Computer Science or a related discipline, or equivalent practical experience
  • Experience designing and developing complex commercial software systems.
  • Experience designing and implementing graphical user interfaces using a high-level toolkit (ideally Qt) on Windows and/or Linux.
  • Object-oriented design
  • Appreciation for good, clean API design and elegant, generic frameworks which are satisfying to use, maintain and extend.
  • Excellent English written and verbal communication skills
  • Solid organizational skills; able to handle multiple tasks/projects simultaneously
  • Strong problem-solving skills


Experience with one or more is a plus:

  • Familiarity with commercial CAD and/or PLM tools.
  • Familiarity with geometry meshing packages and related concepts.
  • Experience with one or more toolkits for 3D graphics, such as OpenGL, OpenSceneGraph or HOOPS
  • Python scripting language
  • General physics familiarity and/or previous exposure to fluid dynamics


Compensation & Benefits

Dassault Systèmes offers an excellent salary with potential for bonus, commensurate with experience. Benefits include a choice of plans providing comprehensive coverage for medical, dental, vision care for employee & dependents as well as employee life, short & long term disability, tuition reimbursement, immediate 401K enrollment, 401K match (50 cents on the dollar, up to the first 8% of your eligible compensation that you contribute based on match eligibility criteria), flexible time off policy, and 9 paid holidays.
