About Etched
Etched is building hardware for frontier intelligence. We co-design chips, racks, software, and manufacturing to deliver best-in-class throughput and latency across both prefill and decode workloads. Our first products are heavily focused on inference. Backed by hundreds of millions from top-tier investors and staffed by leading engineers, Etched is redefining the infrastructure layer for the fastest growing industry in history.
Job Summary
We are looking for a Lead Chip Simulation Engineer to drive the technical direction and development of our custom AI accelerator simulation infrastructure.
Our chip simulation team builds the hardware models that enable software development, debugging, and hardware-software co-design before silicon is available.
In this role, you will guide engineers working on our bit-accurate, cycle-aware chip simulator, review designs and code, and ensure the team builds accurate, performant, and maintainable simulation infrastructure. You’ll work closely with hardware architects, firmware, kernel, and software teams to identify technical challenges, set priorities, and enable early development of our full software stack.
This is a highly technical leadership role for someone who enjoys mentoring engineers, solving complex systems problems, and staying close to the code.
Key Responsibilities
•
Provide technical leadership for the chip simulation team, guiding engineers through architecture, implementation, debugging, and performance optimization.
•
Own the technical direction of our simulation infrastructure, ensuring accuracy, scalability, performance, and maintainability.
•
Lead design and code reviews, establishing engineering best practices and maintaining a high bar for code quality.
•
Mentor and support engineers, helping them navigate complex technical challenges.
•
Drive hardware-software co-design, partnering with hardware architects and software teams to influence architecture and enable pre-silicon development.
•
Oversee simulator integration, including simulated hardware modules, QEMU-based host integration, and multi-chip simulation.
•
Guide validation and testing strategies to ensure simulation correctness and alignment with hardware specifications.
•
Remain technically hands-on when needed, contributing to critical implementations, debugging, and architectural prototyping.
Representative Projects
•
Lead the development of simulation models for our custom AI accelerator.
•
Guide engineers building and validating bit-accurate and cycle-aware models of on-chip modules.
•
Review and drive integration of simulated chips with QEMU hosts, enabling kernel driver development and host software testing.
•
Define the architecture for multi-chip simulation to validate scale-out and scale-up approaches.
•
Establish code review, testing, and debugging practices to improve simulator accuracy and engineering velocity.
•
Partnering with hardware architects and software engineering leads to resolve complex pre-silicon issues and guide technical decisions.

How we’re different
Etched believes in the Bitter Lesson. We are the first inference-focused frontier AI system, betting early on transformer and transformer-like architectures and on increasing model sizes. Our addressable market is the entirety of inference, unlike many of our competitors.
We are a fully in-person team in San Jose (Santana Row), and greatly value engineering skills. We do not have boundaries between engineering and research, and we expect all of our technical staff to contribute to both and work across disciplines as needed.
