Job Title: Logic Design Engineer Core Instruction Sequencing Unit
Location: Bangalore, Karnataka
Experience: 820 Years
Industry: Semiconductor | Hardware Design

About the Role

We are looking for experienced Logic Design Engineers to join the Processor Development team and contribute to the design of next-generation high-performance CPUs. In this role, you will be responsible for architecting and developing the Instruction Sequencing Unit (ISU) and driving the complete RTL design lifecycle from microarchitecture to silicon validation.

Key Responsibilities
Lead the design and development of the Instruction Sequencing Unit (ISU) for high-performance processor CPUs.
Architect and implement Instruction Dispatch, Issue Queues, Register Renaming, Out-of-Order (OoO) Execution, and Reorder Buffers (ROB).
Develop microarchitecture and RTL for processor core features.
Participate in architecture discussions and present high-level design proposals.
Estimate implementation effort, silicon area, timing,



and wire usage for recent features.
Collaborate with Verification, DFT, Physical Design, Timing, Firmware, and Software teams throughout the development cycle.
Ensure pre-silicon design signoff meets functional, timing, and area goals.
Support post-silicon bring-up, debugging, and hardware validation.
Lead design reviews, mentor engineers, and represent the team in global technical forums.

Required Skills
Solid experience in CPU/Processor Logic Design.
Expertise in Microarchitecture and RTL Design (Verilog/SystemVerilog).
