Research Engineer - Generative AI / Physics

Overview

Recruiting for an SF based deep-tech startup KronosAI - https://kronosai.co/ - building foundation ML models for multi-physics simulation. It's a small, highly technical team - including multiple professors from top colleges like Berkeley, multiple PHDs and even a Nobel Prize winner! Well funded, hybrid environment - actively hiring both researchers and engineers, who want real ownership over foundational work and system-level impact.

The work tackles hard physics problems (EM, acoustics, wave propagation) at the intersection of scientific computing, numerical PDEs, and frontier ML - including neural operators, PINNs, and transformer-based solvers. In parallel, we are actively exploring GenAI and LLM-based systems for physics workflows, from simulation orchestration and reasoning to hybrid ML–PDE pipelines.

Our focus is on generalizable, production-grade foundation models, not one-off surrogates.
