About this role

Lead the design and implementation of a real-time, GPU-accelerated propagation engine for 5G/6G network simulation. Architect ray-tracing algorithms and multi-GPU scaling strategies to predict radio signal propagation through realistic 3D environments at millisecond cadence.

Must have

PhD in computer graphics, high-performance computing, computational electromagnetics, or equivalent experience

8+ years of relevant experience in GPU computing or ray tracing

Hands-on proficiency with CUDA and at least one GPU ray-tracing framework

Track record of writing production-quality GPU code

Proficiency in GPU-friendly spatial data structures including BVH and hash maps

Ability to reason about memory hierarchy, occupancy, and compute-vs-bandwidth trade-offs

Working knowledge of electromagnetic wave propagation phenomena

Impactful publications in GPU ray tracing, real-time rendering, or deterministic propagation modelling
