Job Description
Oversees definition, design, verification, and documentation for SoC (System on a Chip) development. Determines architecture design, logic design, and system simulation. Defines module interfaces/formats for simulation. Performs Logic design for integration of cell libraries, functional units and sub-systems into SoC full chip designs, Register Transfer Level coding, and simulation for SoCs. Contributes to the development of multidimensional designs involving the layout of complex integrated circuits. Performs all aspects of the SoC design flow from high-level design to synthesis, place and route, timing and power to create a design database that is ready for manufacturing. Analyzes equipment to establish operation infrastructure, conducts experimental tests, and evaluates results. May also review vendor capability to support development. Job Purpose We are seeking an experienced RTL Design Engineer to drive the architecture, design, implementation, and optimization of complex digital logic for next-generation NAND Flash memory–based SSD controllers. This role involves translating system-level requirements into efficient microarchitecture and synthesizable RTL, driving design tradeoffs across performance, power, and area (PPA), and delivering high-quality designs through ASIC implementation and silicon validation. You will work at the intersection of digital design, computer architecture, NAND Flash technology, and storage systems, partnering with architecture, firmware, verification, physical design, and silicon validation teams to develop scalable and reliable controller solutions for advanced SSD products.
Key Responsibilities
- RTL Design and Microarchitecture- Architect, design, and implement complex RTL modules using Verilog/SystemVerilog for NAND Flash memory–based SSD controllers.Translate system and microarchitecture specifications into efficient, synthesizable, reusable, and maintainable RTL.Drive microarchitecture tradeoffs involving throughput, latency, buffering, concurrency, resource utilization, and scalability.Design and optimize controller pipelines, state machines, arbitration logic, queues, FIFOs, DMA engines, and memory interfaces.
- NAND Flash Controller Design- Develop and optimize hardware logic for NAND command sequencing, interface control, data transfer, status handling, error recovery, and timing management. Understand NAND Flash read, program, and erase behavior, including device timing constraints, operating modes, error conditions, and technology-specific requirements. Design controller logic that supports high channel utilization, parallel NAND operations, efficient resource scheduling, and robust error handling. Collaborate with firmware and architecture teams on hardware/software partitioning and optimization of controller functionality.
- Performance, Power, and Area Optimization- Analyze and optimize RTL to meet stringent timing, throughput, latency, power, and silicon-area targets. Identify critical timing paths, pipeline bottlenecks, resource conflicts, and inefficient logic structures. Drive design improvements through architectural changes, logic restructuring, pipelining, resource sharing, and power-aware design techniques. Evaluate synthesis and static timing analysis reports and work with physical design teams to resolve timing and implementation challenges.
- ASIC Design and Integration- Own RTL development through synthesis readiness, subsystem integration, and ASIC implementation handoff. Ensure design quality through lint, clock-domain crossing (CDC), reset-domain crossing (RDC), and design-rule checks as applicable. Address clocking, reset, initialization, parameterization, and low-power requirements. Collaborate with design verification teams to define verification strategies, resolve functional issues, and achieve robust design coverage. Support pre-silicon emulation, silicon bring-up, post-silicon debug, and root-cause analysis of hardware issues.
- Data Integrity and Reliability- Integrate or develop interfaces to ECC/LDPC engines, data-protection logic, and other reliability-related controller subsystems. Implement robust error detection, status reporting, recovery sequencing, and fault-handling mechanisms. Collaborate with reliability and firmware teams to address NAND error behavior, data integrity, and system-level fault scenarios.
- Technical Leadership and Collaboration- Drive design reviews, provide technical guidance to team members, and promote RTL coding and design best practices. Work closely with firmware, architecture, verification, physical design, NAND technology, and validation teams to resolve cross-functional issues. Identify design risks early, evaluate alternative implementations, and drive issues to closure. Contribute to design methodologies, automation, technical documentation, and continuous improvements in ASIC development efficiency.
