Weather Forecast Numerical Software Specialist — NWP, High-Fidelity CFD and GPU Computing

ph3Weather Forecast Numerical Software Specialist — NWP, High-Fidelity CFD and GPU Computing /h3pFull-time position in a deep-tech RD team building a new scale-resolved simulation code, designed from the ground up for native GPU execution, and extending it toward weather forecasting and climate-related applications. /ph3About the Company /h3pPrediQT Technologies develops a new generation of high-fidelity, scale-resolved CFD software for industrial applications. Unlike incremental improvements to legacy solvers, our SuRF technology is being built as a new code, designed from the start for scale-resolved physics, native GPU execution and future integration with GenAI and quantum computing capabilities. Our ambition is to change the simulation paradigm by delivering a new level of accuracy, reliability and engineering productivity for industrial flow simulation. /ppIndustrial 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. /ppJoin a creative and ambitious deep-tech team working at the frontier of numerical simulation, native GPU computing, GenAI and quantum computing. Thisis not a maintenance or porting role on an existing legacy codebase: itis an opportunity to help build a new scale-resolved industrialsimulation code from an early stage. We value scientific excellence, engineering rigor, intellectual honesty and teamwork. PrediQT is headquartered in Brussels, with quantum RD activities in the Paris/Saclay ecosystem. /ph3About the Role /h3pWe are looking for a numerical software specialist or computational scientist to join the RD team developing PrediQT’s new scale-resolved, GPU-native simulation technology for weather forecasting. You will contribute to the design, implementation and validation of a new high-fidelity code, extending solver numerics and algorithms toward weather and climate applications, with a strong focus on numerical weather prediction, native GPU implementation and rigorous validation. /ph3Responsibilities /h3ulliExtend PrediQT’s solver numerics and algorithms toward weather forecasting and climate-related applications. /liliContribute to the design and implementation of a new GPU-native, performance-critical scientific code rather than simply porting an existing legacy solver. /liliWork with numerical weather prediction workflows, with particular interest in WRF or similar NWP codes. /liliTest and validate new developments on verification cases, documented experiments and relevant weather-forecasting benchmarks. /liliContribute to technical documentation, scientific publications and conference presentations in CFD, NWP, weather and climate science. /li /ulh3Qualifications /h3ulliThe ideal candidate has strong experience in numerical methods, scientific software implementation and weather applications. We are looking for someone able to bridge high-fidelity CFD, NWP workflows and GPU-based implementation while maintaining scientific rigor and practical engineering discipline. /liliA Master’sdegree or PhD in computer science, applied mathematics, mechanical oraerospace engineering, meteorology, atmospheric science, scientific computing or a closely related field is strongly preferred. /li /ulh3Required Skills /h3ulliDeep knowledge of numerical weather prediction codes at implementation level, with a focus on WRF or comparable models. /liliStrong understanding of advanced CFD numerical methods and their relationship to atmospheric or environmental flow simulation. /liliHands-on programming experience in C, C++, CUDA and Python for scientific computing. /liliGood understanding of GPU architecture, native GPU programming and performance optimization for large-scale numerical codes. /liliAbility to analyse simulation data, validate numerical developments and document results clearly. /li /ulh3Soft Skills /h3ulliExcellent analytical and problem-solving skills, intellectual curiosity and scientific rigor. /liliCreative, communicative and collaborative mindset in a high-level RD team. /liliInterest in weather and climate science and the industrial impact of high-fidelity forecasting tools. /liliAutonomy, pragmatism and team spirit in an early-stage deep-tech environment. /li /ulh3Preferred Skills /h3ulliExperience with advanced CFD numerical methods, high-order schemes or scale-resolved simulation approaches. /liliExperience with CUDA, Kokkos, MPI, OpenMP, OpenACC or other HPC portability and parallelization frameworks. /liliPrior work on weather, climate, atmospheric flows or environmental simulation software. /li /ulh3Pay range and compensation package /h3pWe offer a competitive compensation package, including salary, stock options and social benefits.
