Responsibilities

Lead the microarchitecture development of custom coherent interconnect IP and/or last-level cache (LLC) blocks for next-generation designs.
Drive key aspects of coherent interconnect RTL design, including performance and power optimization, logic debug, and timing closure.
Own the development and delivery of custom coherent interconnect IP and/or LLC blocks, ensuring high-quality execution and timely project completion.
Collaborate closely with system architects to define and develop next-generation coherent interconnect and LLC architectures.
Drive microarchitecture definition and specification, from early architectural exploration and microarchitectural research through detailed specification development and refinement.
Partner with verification teams to ensure functional correctness and robust validation of the design.
Develop high-quality RTL implementations that meet performance, power, and area (PPA) goals.
Work with performance and power teams to optimize architecture and RTL implementations for efficiency and scalability.
Collaborate with physical design and CAD teams to resolve implementation, timing, and integration challenges.
Provide technical leadership and mentorship to junior engineers across the team.
