Software Engineer – High-Fidelity Multiphase CFD (New College Grad with PhD)

At Cadence, we hire and develop leaders and innovators who want to make an impact on the world of technology.
Department:
CFD Research & Development
We are seeking a
Lead Software Engineer
to join our R&D team to support
large-scale, high-fidelity simulation
of
multiphase turbulent flows
. This position involves developing parallel simulation codes, implementing advanced numerical methods, and validating models for liquid
spray and atomization
. You will work on challenging problems in computational fluid dynamics (CFD) and contribute to innovative solutions in industrial and scientific applications.
Key Responsibilities

• Design and implement simulation software for multiphase flows using concepts from Volume-of-Fluid (VOF) and diffuse interface methods.
• Develop GPU-accelerated numerical algorithms for both incompressible and compressible regimes using an unstructured LES solver.
• Optimize codes for high-performance computing (HPC) environments leveraging C++, MPI, CUDA, and HIP.
• Conduct rigorous numerical analysis to ensure accuracy and stability of simulation codes.
• Validate models against experimental data, particularly for spray dynamics.
• Contribute to research in physics-based subgrid-scale modeling for interfacial flows.
• Collaborate with cross-functional teams to integrate simulation tools into broader workflows.

Required Qualifications

• PhD in Mechanical Engineering, Aerospace Engineering, Applied Mathematics, or related field. (Summer 2026)
• Proven R&D experience in developing CFD simulation codes for multiphase flows.
• Strong background in multiphase flow, LES, and numerical analysis.
• Proficiency in C++, MPI, and GPU programming (CUDA/HIP).
• Experience with high-performance computing and parallelization techniques.
• Familiarity with compressible flow, combustion modeling, and spray validation.
