Software Developer - Combustion Modelling (Finite Volume CFD)

We are seeking a highly motivated Software Developer with expertise in combustion modelling and finite volume CFD methods to join our CFD development team. In this role, you will contribute to the development, implementation, and optimization of advanced numerical models for reactive flows, supporting cutting-edge applications in powertrain, e mobility, thermal systems, and energy conversion.

YOUR RESPONSIBILITIES:

•    Develop, implement, and maintain combustion and reactive-flow models within a finite volume CFD solver environment.
•    Enhance numerical algorithms to improve stability, accuracy, and computational performance, including adaptation for parallel and high performance computing environments.
•    Integrate new physical models into existing codebases following established software development processes and coding standards.
•    Conduct verification and validation of implemented models using experimental data and standardized CFD benchmarks.
•    Prepare technical documentation, including model descriptions, user guidelines, and internal design documentation.

YOUR PROFILE:

Required Qualifications
•    PhD (preferably PhD but possible also with master’s degree) in Mechanical Engineering, Chemical Engineering, Physics, Computational Engineering, or a related technical discipline.
•    Strong theoretical understanding of combustion, fluid mechanics, thermodynamics, and heat transfer.
•    Experience with finite volume CFD methods and numerical discretization techniques.
•    Proficiency in C++ or Fortran for scientific or engineering software development; additional experience with Python is advantageous.
•    Experience working with version control systems (e.g., Git) and standard software development workflows. 

Preferred Qualifications
•    Experience with chemical kinetics, mechanism reduction, or chemistry solvers (e.g., CHEMKIN, Cantera).
•    Experience in high performance computing: MPI, multi-threading, or GPU acceleration.
•    Background with commercial or open source CFD tools (e.g., OpenFOAM, CCM+, CONVERGE, Ansys).
•    Understanding of automotive, aerospace, or energy sector applications.

Key Competencies
•    Strong analytical and problem solving skills.
•    Ability to work effectively in multidisciplinary and international teams.
•    Clear and structured communication skills.
•    High degree of self initiative, accountability, and organizational ability.

WE OFFER:

•    Working in a small, focused team with motivated developers
•    Work on the company's own product (established software packages)
•    Full creative & professional freedom, no micromanagement
•    International teams and dynamic environment
•    Comfortable offices (no open space)
•    Remote work option
•    Flexible working hours
