Emulation Engineer

About the Team

OpenAI’s Hardware organization develops silicon and system-level solutions designed for the unique demands of advanced AI workloads. The team is responsible for building the next generation of AI-native silicon while working closely with software and research partners to co-design hardware tightly integrated with AI models. In addition to delivering production-grade silicon for OpenAI’s supercomputing infrastructure, the team also creates custom design tools and methodologies that accelerate innovation and enable hardware optimized specifically for AI.

About the Role

We’re seeking an experienced Emulation Engineer to help accelerate the development and validation of OpenAI’s custom ML accelerators. In this role, you’ll architect hardware emulation platforms to enable early software development, system-level testing, and fast iteration cycles across hardware and software teams. You’ll be a critical bridge between design, DV, performance, and software teams—enabling scalable, high-fidelity validation of next-generation AI silicon.

Key Responsibilities

• Build and maintain pre-silicon emulation platforms using commercial emulators (e.g., Veloce, Palladium, ZeBu)
• Work with RTL and DV teams to bring-up and validate designs on emulation systems.
• Develop transactors, models, and acceleration-aware testbenches to maximize throughput and observability.
• Enable fast and reliable software bring-up by integrating firmware and drivers with emulated hardware.
• Partner with performance, software, and validation teams to root cause bugs and optimize system behavior.
• Support continuous regression infrastructure and automation for long-running, system-scale workloads.

Qualifications

• BS/MS in EE/CE/CS or equivalent with 5+ years of experience in emulation or FPGA-based prototyping.
• Deep familiarity with RTL design (SystemVerilog/VHDL), simulation, and emulation flows.
• Experience with at least one major emulation platform (Palladium, Veloce, or ZeBu) and their toolchains.
• Experience with building large scale emulation systems, optimizing build reliability, efficiency and performance.
• Experience with integrating various IO speedbridge and memory components.
• Strong scripting skills (Python, Tcl, Shell) and experience building automation infrastructure.
• Ability to debug complex HW/SW interactions and performance bottlenecks in large systems.
• Experience in ML accelerator or SoC emulation environments is a plus.

To comply with U.S. export control laws and regulations, candidates for this role may need to meet certain legal status requirements as provided in those laws and regulations.
