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. Qualifications Required Qualifications • Master's or PhD degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field. • Typically 3+ years of relevant experience in RTL design and ASIC development. • Strong proficiency in Verilog/SystemVerilog and experience designing complex, synthesizable RTL. • Deep understanding of digital logic, sequential design, finite-state machines, pipelining, timing closure, and computer architecture. • Experience with ASIC design flows, including RTL simulation, lint, synthesis, static timing analysis (STA), and design integration. • Experience analyzing timing reports and optimizing RTL to meet performance, power, and area requirements. • Strong understanding of clocking, reset architecture, CDC, and robust hardware design practices. • Proficiency in scripting or programming using Python, Tcl, Perl, or C/C++ to automate design tasks and analyze results. • Demonstrated ability to debug complex hardware issues, perform root-cause analysis, and collaborate effectively across engineering teams. Preferred Qualifications • Experience designing NAND Flash memory controllers, SSD controllers, or other high-performance storage ASICs. • Strong understanding of SSD architecture, Flash Translation Layer (FTL) interactions, NAND parallelism, and storage data paths. • Experience with NAND interfaces and protocols, including ONFI or Toggle-mode interfaces, and associated timing and command requirements. • Knowledge of NAND Flash reliability characteristics, error management, ECC/LDPC, bad-block handling, and read-retry mechanisms. • Experience designing high-throughput data paths, DMA engines, queue management, arbitration, buffering, and memory interfaces. • Familiarity with industry-standard EDA tools for simulation, synthesis, lint, CDC/RDC, and static timing analysis. • Experience with low-power design techniques, clock gating, power management, and PPA optimization. • Experience with formal verification, hardware emulation, FPGA prototyping, or post-silicon debug. • Understanding of interface protocols such as AXI, AHB, PCIe, or NVMe-related controller interfaces. • Experience with design automation, RTL quality analysis, or AI-assisted hardware design and verification workflows. • A track record of technical ownership, cross-functional problem-solving, and delivery of complex ASIC designs from specification through silicon validation.
