DensityAI
DensityAI designs AI accelerator chips and a complete stack—from silicon and boards to racks and software—for training and inference in data-center environments. The privately held company is headquartered in Mountain View, CA, and targets cloud providers and enterprises building scalable AI infrastructure. Its programs span first-silicon bring-up through scale-out systems, with roles across hardware design, verification, and systems software.
Open Positions at DensityAI
4 open positions
Build and own high-performance software simulators for an AI accelerator, enabling compiler, runtime, and architecture teams to develop and validate software before silicon exists. The role combines modern C++, Python infrastructure, computer architecture, performance modeling, and pre-silicon validation.
Build platform firmware that powers, secures, monitors, and debugs AI accelerator systems from boot through large-scale operation. This hands-on role spans embedded controllers, secure boot, power management, telemetry, and hardware bring-up.
Own the design of MLIR dialects and lowering passes that connect AI frameworks to DensityAI’s custom accelerator silicon. This role focuses on tensor IR, distributed execution, and async/streaming compiler semantics from first silicon through scale-out.
Own LLVM backend development for a custom accelerator ISA, spanning instruction selection, register allocation, scheduling, and linker support. This role partners closely with chip-design and software teams from first silicon through scale-out.
