Scale-Resolved CFD Solver Developer — High-Order Methods, C++/CUDA and Turbomachinery

Full-timeposition in a deep-tech R&D team developing next-generationhigh-fidelity flow simulation software for aerospace, propulsion, energy and weather forecasting.

About the Company

PrediQT Technologies develops next-generation high-fidelity, scale-resolved CFD software for industrial applications. Our ambition is to change the simulation paradigm by combining advanced numerical methods, GPU-native performance and, in the longer term, quantum computing capabilities. Our SuRF solver and GenAI-based engineering platform are designed to deliver a new level of accuracy, reliability and engineering productivity for industrial flow simulation.

Industrial demand is shifting toward simulations that can resolve complex unsteady flow physics with higher fidelity, while remainingusable in real engineering workflows. This evolution, together withmajor advances in numerical methods, GPU computing, quantum computing and GenAI, led to the creation of PrediQT Technologies.

Joina creative and ambitious deep-tech team working at the frontier ofnumerical simulation, GPU computing, GenAI and quantum computing. Wevalue scientific excellence, engineering rigor, intellectual honesty and teamwork. PrediQTis headquartered in Brussels, in a green area close to public transportand within easy reach of Paris, Amsterdam and London. The role offersthe opportunity to help build a new generation of industrial simulationsoftware from an early stage.

About the Role

Thisis a full-time role for a senior CFD solver developer or computationalscientist. You will join the R&D team developing our next-generationhigh-fidelity flow simulation software for turbomachinery. You willwork directly on scale-resolved CFD numerics, high-order methods, solver architecture, GPU implementation and verification against demanding reference cases.

Responsibilities

Design, implement and optimize native GPU kernels and solver components in modern C++ and CUDA.

Verify and validate new numerical developments on canonical CFD benchmarks, documented experiments and industrially relevant turbomachinery or propulsion cases.

Contribute to scientific publications and represent PrediQT at leading CFD, aerospace, propulsion, turbomachinery, energy and weather-forecasting conferences.

Write clear technical documentation, verification reports and, where appropriate, peer-reviewed scientific papers.

Qualifications

Weare looking for candidates with a strong research and implementationbackground in CFD solver development. The ideal candidate has a PhD orequivalent research experience, has developed or substantially contributedto scale-resolved CFD codes, and is comfortable moving from numericalformulation to robust, high-performance C++/CUDA implementation.

This role is intended for candidates who have programmed the core numerical engine of CFD codes, not only used CFD packagesor extended them through UDFs, scripts or isolated physical models.Relevant experience should include hands-on work on discretizationschemes, fluxes, time integration, linear or nonlinear solvers, datastructures, parallelization and performance-critical implementation.

APhD in computational fluid dynamics, applied mathematics, mechanical oraerospace engineering, scientific computing, or a closely related fieldis strongly preferred. Exceptional candidates with equivalentresearch-level experience in CFD solver development may also beconsidered.

Required Skills

Deephands-on knowledge of advanced CFD numerical methods at implementationlevel, including finite-volume and high-order approaches forcompressible, turbulent or unsteady flows.

Direct experience with high-order CFD methods such as Discontinuous Galerkin, spectral difference, flux reconstruction or related scale-resolved approaches.

Expert-level modern C++ and strong CUDA programming skills; Python experience for tooling, testing and analysis is a plus.

Strong expertise in scale-resolved CFD, including LES, DNS, hybrid RANS/LES or equivalent high-fidelity simulation approaches.

Solid understanding of GPU architecture, memory hierarchy, parallel performance bottlenecks and optimization strategies for large-scale scientific computing.

Soft Skills

Excellent analytical and problem-solving skills, intellectual curiosity, scientific rigor, clear communication and the ability to work effectively in a high-level R&D team.

Creative, communicative and team working

Experience in aerospace, propulsion, turbomachinery, energy, weather or climate applications is a strong advantage.

Preferred Skills

Prior experience developing production or research CFD solvers, especially for turbomachinery, compressible flows, multiphysics or industrial high-performance simulations.

Experience with CUDA is highly valued; experience with Kokkos, MPI, OpenMP, OpenACC or other HPC portability and parallelization frameworks is a plus.

Pay range and compensation package

We offer a competitive compensation package, including salary, stock options and social benefits. This is an opportunity to join PrediQTat an early stage and contribute directly to the development of a newgeneration of high-fidelity industrial simulation software.
