Performance Engineer, Hardware
At River AI, our mission is to create personal AI owned and shaped by each individual. To achieve this, we are rewriting the entire stack from scratch: personal hardware for local inference, custom training infrastructure, next-generation UIs, and frontier deep learning research.
Who we are
We are scientists, engineers, and builders from the industry's top tech companies and AI labs. We bring a proven track record of scaling consumer systems for hundreds of millions of users and architecting the pre-training infrastructure behind today's frontier models.
About the Role
We are seeking exceptional hardware performance engineers to architect, model, and correlate high-performance custom silicon. You will develop high-fidelity simulators to predict how our AI accelerator architecture and SoC system will handle real-world AI models. You will take ownership of performance models, ISA and kernel optimization, and FPGA emulators for software development. You will be collaborating both up and down the stack with compiler, IR, and software teams, as well as with RTL design engineers.
What You’ll Do
- Simulator Development: Design and implement high-performance and functional models of complex hardware using C++ and/or SystemC.
- Micro-architectural Exploration: Cond
