Normal Computing | Build with Us
Normal is an applied AI company solving the hardest problems in AI and silicon. We build foundational hardware and software for the semiconductor industry, critical AI infrastructure, and the broader systems that power our world, in partnership with the world's most advanced institutions. We work as one team across New York City, Silicon Valley (Mountain View), London, Copenhagen, and Seoul.
The Role
As a Performance Modeling Engineer at Normal, you will build the transaction-level model (TLM) of our physics-inspired ASICs. It is the model that sits between RTL and the rest of our modeling stack, and that both our architects and our verification team rely on.
You will own the path from RTL to the numerical performance results. You will correlate the TLM against RTL, FPGA prototypes, and synthesis results, then turn it into calibrated latency, bandwidth and energy parameters for kernel-level models. You will work closely with the architecture, hardware design and DV teams, using their feedback to help refine our end-to-end system.
The through-line is your modeling expertise, applied to an architecture that computes differently from anything you have modeled before, and to the AI that is changing how AI workloads get done. This is a seat for a performance modeling engineer who wants their craft to compound rather than repeat. Ultimately Normal Computing will build a next generation system with 100-1000× improvement in AI inference, and your work will make this possible.
What You Will Own
Transaction-Level Model: Build and maintain a cycle-accurate approximate TLM of our compute tiles, memory hierarchy, and interconnect in an appropriate language (SystemC, C++ or Python). The code must be fast enough to simulate real workloads and accurate enough to make production design decisions
Feeding the Modeling Stack: Translate TLM and RTL results combined with physical design into calibrated parameters (latency, bandwidth, energy, utilization, occupancy, etc.) to enable end-to-end system level performance prediction on AI workloads
Verification Reference: Provide the TLM as a reference “golden model” for DV, including transaction level scoreboards and performance checks and work with the DV and RTL team to ensure RTL produces the desired end-target behavior so that the TLM reflects the RTL and the RTL reflects the TLM.
Planning and Performance Feedback: Plan modeling work against the hardware roadmap and run sensitivity studies on key hardware parameters (buffer sizes, interface widths, scheduling policies, and bus configurations) to turn results into clear recommendations for the architecture and hardware teams
What Makes You a Great Fit
5+ years of experience in performance modeling at a major semiconductor company
Demonstrated proficiency in understanding architectures and transforming that to performant modeling code
Use of various modeling techniques and languages
Excellent written and spoken communication skills
Bonus Points
Experience with AI acceleration hardware
Experience with architecture-level modeling and cost tools such as AccelForge, Timeloop/Accelergy, CACTI, McPAT, or gem6
Experience with DV methodology
Hands-on use of LLMs or agentic tools in development workflows
Exposure to analog, mixed-signal, or unconventional compute
Experience with memory interfaces (LPDDR, HBM, DDR) and other I/O
