Software Engineer - Adjoint - 294222

Position Overview

Siemens PLM is seeking software development professionals to contribute to our Adjoint (ADJ) program. The main focus of the ADJ program, a unit within our Computational Fluid Dynamics (CFD) division, is the development of methodologies to provide sensitivity derivatives with respect to various objectives by means of discrete adjoints within Siemens PLM's flagship multi-physics simulation product, Simcenter STAR-CCM+.

Simcenter STAR-CCM+ contains accurate, robust and efficient finite-volume flow solvers for modeling of complex industrial flows typical of such applications as turbomachinery, external aerodynamics, and internal combustion engines.

The ADJ program is responsible for the design and implementation of a framework to facilitate differentiation of physical models and solution algorithms within our simulation software. As a member of the ADJ program you will be expected to contribute to both development of new features 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.


As a member of the ADJ program, your specific responsibilities will include:

  • Ensuring high-quality and robust implementation of core functionality providing differentiation of solver components using discrete adjoint methods in STAR-CCM+
  • Supporting maintenance of our existing capability (bug fixing, code refactoring, etc.)
  • Design and development of new features based on requests from both product management and internal strategic initiatives
  • Participating in regularly scheduled team meetings and contributing ideas to drive innovation in our technology
  • Supporting other developers through design discussion and code review

Required Knowledge/Skills, Education, and Experience

Candidates applying for this position are required to have the following skills and experience:

  • A Master’s or PhD degree in engineering or physical science subject area
  • 2 years’ experience in commercial CFD software development, or 5 years’ experience in non-commercial CFD software development
  • Expertise in implementing adjoint methods within numerical simulation software for the solution of the Navier-Stokes equations
  • Expertise in object-oriented C++14/17 software development, including template meta-programming
  • Expertise in high-fidelity and high-performance parallel CFD algorithms
  • Expertise in development of complex software applications using modern design patterns and principles

Preferred Knowledge/Skills, Education, and Experience

In addition, preference will be given to candidates with the following skills and experience:

  • Expertise in areas of physical science: thermodynamics, heat transfer, multiphase, or combustion
  • Expertise in programming for GPGPU
  • Expertise in application of CFD methods: porous media, turbomachinery, vehicle aerodynamics, internal combustion engines
  • Expertise in Java programming
  • Experience in multi-team, collaborative software development including source control and collaborative design and code reviews
