Define scalable modeling architectures that evolve with changing hardware designs and microarchitecture updates
Collaborate with architecture and RTL teams to ensure model alignment with hardware intent and implementation details
Design and develop software interfaces and APIs that allow software teams to interact with hardware models as if using physical silicon
Build emulator-style frameworks that support register-level access, memory inspection, and controlled execution of AI workloads
Implement debugging, introspection, and tracing capabilities to support deep analysis of hardware and model behavior
Develop integrated performance profiling and analysis tools within the modeling environment
Enable detailed inspection and modification of memory and register state to support debug, optimization, and issue triage
Provide modeling infrastructure to support hardware-software co-verification and system-level validation
Partner with verification teams to ensure model correctness, completeness, and alignment with verification scenarios
Support FPGA prototyping, emulation, and early validation flows as required
Provide expert technical guidance on hardware modeling methodologies, best practices, and tooling
Influence modeling standards and approaches across programs to improve scalability, accuracy, and developer productivity
Communicate complex modeling concepts and limitations clearly to both technical and non-technical stakeholders
Qualification
Required
Expert communicator across global, cross-cultural, and cross-functional teams
