Our team builds virtual platforms — full-system C++ and SystemC models of these custom SoCs — that let software teams start development months before silicon arrives. For Trainium3, our virtual platform enabled running a full training workload within 12 hours of first silicon. We're looking for a software engineer to build and own the models and infrastructure that make this possible. ### What you'll do - Build and own functional models of SoC subsystems that integrate into our full-system virtual platform, used by firmware, driver, runtime, and application software teams - Develop and improve the virtual platform infrastructure: QEMU integration, simulation performance, build and release tooling, and customer-facing documentation - Design models for usability and performance — your customers are software engineers who need to run real workloads on your platform efficiently - Work with software teams (your primary customers) to understand their workflows, debug issues on the platform, and shape the model to maximize their productivity - Drive simulation performance improvements so the platform can handle increasingly complex workloads at scale - Contribute to model architecture decisions — choosing the right level of abstraction and fidelity for each subsystem based on customer needs ### Why this role is interesting - You'll own a product that software teams across AWS depend on — they literally can't start development without your virtual platform - The engineering challenges are genuinely interesting: full-system simulation, multi-subsystem integration, QEMU development, performance optimization at scale - You'll see the direct impact of your work when software teams hit the ground running on new silicon - As the team grows, there's a path into architectural modeling — using the platform to explore design alternatives and influence chip architecture - Small team, startup pace, big impact inside AWS's custom silicon org ### You will thrive in this role if you - Have built functional models, virtual platforms, or system-level simulations for SoCs, ASICs, GPUs, or CPUs - Think of yourself as a software engineer first, with deep domain knowledge in chip architecture - Are comfortable in C++ or SystemC, and familiar with Python for tooling - Care about your customers' experience — you think about usability, documentation, and reliability, not just model accuracy - Are interested in expanding into performance or architectural modeling as the team scales - Enjoy working on a small, high-impact team where you own significant pieces of the stack No ML background needed. You'll learn the ML accelerator domain on the job. This role can be based in Cupertino, CA or Austin, TX. ## At a glance - Posted by the employer: Mar 27, 2026 - First seen by OpenNash: Jul 10, 2026 - Last checked: Nov 1, 2026 - Listed for: 219 days - Location: US, CA, Cupertino[Apply on Amazon’s careers site →](https://www.amazon.jobs/en/jobs/10378117/virtual-platform-software-engineer-annapurna-labs-machine-learning-accelerators-aws) ## Hiring at Amazon - Open jobs: 19,174 - New in the last 7 days: After two weekly collections - Tracked since: Jul 10, 2026 [All Amazon jobs](https://jobs.opennash.com/companies/amazon/) · [Weekly hiring report](/reports/hiring/) ## More jobs at Amazon ### [C/C++ Hardware / Software Co-Design SDE, Machine Learning Acceleration Systems](https://jobs.opennash.com/companies/amazon/jobs/7371d5b98addffb42049/) US, CA, Cupertino ### [Firmware Engineer, Annapurna Labs, ML Acceleration - Performance Instrumentation & Developer Tools](https://jobs.opennash.com/companies/amazon/jobs/8fed146c593af012b642/) US, CA, Cupertino ### [Lead SDE C/C++ Hardware/Software Co-Design, Machine Learning Acceleration Systems](https://jobs.opennash.com/companies/amazon/jobs/388aac27af0d6b2c7923/) US, CA, Cupertino ### [Lead Software Engineer, ML Network Stack - Annapurna Labs](https://jobs.opennash.com/companies/amazon/jobs/c6dae1c9fdf3a91c8aa2/) US, CA, Cupertino ## Similar jobs at other companies ### [Software Virtual Platform/Simulation Sr. / Staff Engineer - Multiple Levels](https://jobs.opennash.com/companies/qualcomm/jobs/c506bb29f8b854128a2b/) Qualcomm · Santa Clara, California, United States of America ### [Senior Platform Software Engineer (OCI - Developer Platform)](https://jobs.opennash.com/companies/oracle/jobs/dd53310762b7dbb9f8ee/) Oracle · Nashville, TN, United States ### [Software Engineer III - Platform Engineer](https://jobs.opennash.com/companies/jpmorganchase/jobs/38a1b5fc5eab10c967ae/) JPMorganChase · Wilmington, DE, United States ### [Sr Engineer, Software/Information Platform](https://jobs.opennash.com/companies/cardinal-health/jobs/97fd7de2a66203a55ce7/) Cardinal Health · International OpenNash lists jobs from employers’ own careers sites and does not handle applications.
