AI Hardware Performance Engineer – SoC & Simulator

River AI is seeking a hardware performance engineer to architect and model high-performance silicon, developing simulators to predict AI accelerator and SoC behavior for real-world models. You will own performance models, ISA/kernel optimization, and FPGA emulators for software development.

You will collaborate with compiler, IR, and RTL teams across the stack, validating models against RTL and emulators, and identifying bottlenecks from ILP to bandwidth limits within a fast-moving AI hardware
