About the role

Key responsibilities & impact

Lead the design and implementation of a real‑time, GPU‑accelerated propagation engine
Architect and implement a GPU ray‑tracing engine that operates at two time scales
Produce volumetric radio maps — coverage, SINR, and best‑server maps at multiple resolutions
Deliver per‑link multipath channel updates at the millisecond cadence that a production RAN stack requires
Lay the foundations for real‑time ray tracing on GPU hardware — algorithms, data structures, and multi‑GPU scaling strategies

Requirements

What you’ll need

PhD in computer graphics, high‑performance computing, computational electromagnetics, or a closely related field (or equivalent experience)
8+ years of relevant experience
Hands‑on proficiency with CUDA and at least one GPU ray‑tracing framework (OptiX, Vulkan RT, Embree)
Proficiency in GPU‑friendly spatial data structures (BVH, space‑filling curves, hash maps)
Working knowledge of electromagnetic wave propagation phenomena (reflection, transmission, diffraction, scattering)
Impactful publications in GPU ray tracing, real‑time rendering, or deterministic propagation modelling.
