We empower our people to stay resilient and relevant in a constantly changing world. We’re looking for people who are always searching for creative ways to grow and learn. People who want to make a real impact, now and in the future.

Does that sound like you? Then it seems like you’d make a great addition to our vibrant team.

Siemens Software, a business unit of the Siemens Digital Industries, is a leading global provider of software solutions to drive the digital transformation of industry, creating new opportunities for manufacturers to realize innovation.

About the role:

Siemens Digital Industries Software is seeking motivated Computational Fluid Dynamics (CFD) software engineers to join our CFD solver development team.

The primary focus of the CFD solver team, a unit within our Computational Fluid Dynamics (CFD) division, is the conception, design and development of core thermo-fluid flow solver capabilities within Siemens Digital Industries’ flagship multi-physics simulation product, Simcenter STAR-CCM+.

The CFD solver development team is responsible for developing accurate, robust and efficient flow solvers for modeling complex industrial flows, such as turbomachinery, external aerodynamics, and internal combustion engines. As a team member, you will be expected to contribute to both the innovation and development of new features, as well as the improvement and maintenance of existing functionality. Your responsibility will be to ensure a well-designed, high-quality, robust implementation; efficient operation; and good scalability in our highly parallel, client-server platform.

What you’ll be doing:

As a member of the CFD solver development team your specific responsibilities will include:

Design and development of core CFD solver components in Simcenter STAR-CCM+

Ensuring high-quality and robust implementation of core CFD solver components in Simcenter STAR-CCM+

Supporting maintenance and improvement of our existing capability (bug fixing, code refactoring, etc.)

Conception, design and development of new features based on requests from both product management and internal strategic initiatives

Participation in regularly scheduled team meetings and contribution of ideas to drive innovation in our technology

Supporting other developers through design discussion and code review

What you'll bring:

A PhD or Master's degree in engineering, physics, applied mathematics, or a related physical science discipline

Solid understanding of the Navier-Stokes equations and the numerical methods used to solve them

Working knowledge of object-oriented C++ and an interest in building maintainable, well-structured software

Familiarity with computational modelling of fluid flow, ideally in aerodynamic or hydrodynamic applications

Good understanding of software design principles, and a willingness to learn modern design patterns

Familiarity with high-performance computing concepts, including parallel programming and GPU computing

Nice to have:

Coursework or project experience in thermodynamics, heat transfer, multiphase flow, or combustion

Exposure to CFD applications such as vehicle aerodynamics, internal combustion engines, or turbomachinery

Experience with CFD software, either commercial or open-source, through academic projects, internships, or personal work

Experience with source control (such as Git) and participating in code reviews or team-based development
