The Systems Software Engineer role at AWS involves working at the intersection of hardware and software, focusing on both pre-silicon and post-silicon challenges. The team develops SoC models and infrastructure to facilitate SoC validation and system software development. This position requires debugging complex hardware/software interactions and collaborating with various engineering teams to validate hardware/software interfaces. Candidates will contribute to the design of hardware features and build tooling and automation to enhance development processes.

• 6+ years of full software development life cycle experience, including coding standards and operations experience.
• 7+ 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.
• Knowledge of SoC, CPU, GPU, and/or ASIC architecture and micro-architecture.
• 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.
• Experience co-designing hardware/software interfaces with architecture or RTL teams.
• 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 by providing a software perspective early in the chip development cycle.
• Build tooling, test infrastructure, and automation that accelerates development for the team.

• Employees at Amazon are often offered comprehensive health benefits—including multiple medical plan options (no pre-existing condition exclusions, 100% covered in-network preventive care), dental and vision plans, a 24/7 medical advice line from day one, expert second-opinion services, and broad mental-health support with several free counseling sessions (including pediatric).
