Accelerator Systems Software - Member of Technical Staff

Callosum is an intelligent systems company building infrastructure that unifies heterogeneous compute across the full stack. The Member of Technical Staff will develop low-level systems software, including kernels, drivers, firmware, scheduling, and runtime tools, to enable AI inference across diverse accelerator platforms.

Responsibilities:

• Build and maintain kernels, device drivers, and firmware for heterogeneous accelerators
• Design and implement accelerator scheduling at the execution level — kernel launches, dataflow optimisation, and resource management across diverse hardware
• Optimise execution paths for latency, throughput, and resource utilisation across accelerator types
• Work closely with internal teams and hardware vendors to onboard new accelerator platforms
• Contribute to low-level runtime software that bridges our inference stack and the underlying hardware
