The Systems Software Engineer role at AWS involves working at the intersection of hardware and software for custom SoCs. The team focuses on developing SoC models and infrastructure to facilitate validation and accelerate system software development. This position requires debugging complex hardware/software interactions and collaborating with various engineering teams to validate hardware/software interfaces. The role offers the opportunity to contribute to the design of hardware features and build tooling that enhances development efficiency.

• Knowledge of hardware architectures
• 2+ years of professional experience developing firmware, drivers, runtime software, or low-level systems software for custom hardware
• Experience programming in C++, Python, and/or Rust, with a preference for at least two languages
• Experience with collective communication libraries or distributed systems primitives
• Experience debugging using functional models, QEMU, FPGA, or emulators
• Experience with Linux kernel development, device drivers, or bare-metal firmware
• Experience building functional or performance models of SoCs
• Familiarity with PCIe, DMA engines, on-chip interconnects, or network-on-chip architectures
• Experience with performance profiling and optimization of latency-sensitive software
• Experience with multi-threaded, multi-process, or asynchronous programming models

• Develop and own components of SoC models at both single-chip and datacenter-scale levels
• Debug complex hardware/software interactions across the full software stack
• Collaborate with chip architects, RTL designers, modelers, compiler engineers, and ML framework teams
• Contribute to the design of hardware features from a software perspective early in the chip development cycle
• Build tooling, test infrastructure, and automation to accelerate development
