Logic Design Engineer

Job Description

This role is for one of Weekday's clients Min Experience: 8 years JobType: full-time Requirements About the Role: We are looking for a seasoned Logic Design Engineer with expertise in microarchitecture , RISC-V , VLSI , and VHDL , to lead the design and development of the L2 and Last Level Cache (LLC) for high-performance processor systems. This role is critical in delivering industry-leading CPU performance and efficiency by owning the complete lifecycle of cache architecture — from concept to pre-silicon signoff. As a technical leader in the team, you will be responsible for developing the microarchitecture of the cache subsystem, defining the RTL design, and collaborating across cross-functional teams including verification, DFT, physical design, and software/firmware groups to deliver world-class silicon. Key Responsibilities: Architect and design the L2 and LLC blocks for next-generation high-performance RISC-V processor systems. Translate system-level performance requirements — including capacity, latency, bandwidth, and RAS — into efficient, scalable cache architecture and microarchitecture solutions. Drive high-level feature definition and propose architectural enhancements in high-level design discussions. Develop detailed microarchitecture specifications and implement robust RTL designs in VHDL, ensuring performance, area, and power efficiency. Collaborate with the verification team to define verification plans, support testbench development, and debug RTL issues. Interface with DFT and physical design teams to integrate and optimize the cache subsystem for manufacturability and silicon readiness. Engage with firmware and software teams to support system bring-up and low-level programming interface development. Own pre-silicon signoff of the cache subsystem, meeting all functional, timing, and quality goals before tape-out. Continuously analyze performance metrics and identify areas of microarchitecture and logic improvements. Mentor junior engineers, contribute to design reviews, and participate in architecture working groups. Required Skills and Qualifications: 8+ years of experience in logic design and microarchitecture in high-performance CPU or SoC development. Deep expertise in microarchitecture and design of cache systems, memory hierarchies, or complex compute subsystems. Proven experience with RISC-V or RISC-based processor architectures and SoC integration. Proficient in RTL design using VHDL (Verilog/SystemVerilog is a plus). Solid knowledge of VLSI design principles, synthesis, STA, linting, and clock-domain crossing. Strong understanding of SoC design workflows and cache coherency, ECC/parity, and performance optimization techniques. Familiarity with performance modeling, cache hierarchy tradeoffs, and CPU-SoC system design. Excellent communication and collaboration skills to effectively interface with architecture, verification, physical design, and software teams. Preferred Qualifications: Experience with RISC-V core or cache subsystem development in commercial or open-source environments. Familiarity with scripting tools like Python, Perl, or Tcl for design automation and verification. Exposure to tools like Synopsys Design Compiler, VCS, or Cadence Genus and Innovus.
