Senior Library Characterization Engineer

Roles & Responsibilities About the Role: We are looking for a highly skilled Senior IC Design Engineer to join our growing team. You will be responsible for driving and leading the full Standard Cell Library Characterization flow, focusing on delivering high-quality timing and power models for advanced nodes. This role requires cross-functional expertise to integrate model output with the digital physical implementation flow (RTL to GDSII), ensuring optimal Power, Performance, and Area (PPA) optimization, successful signoff, and robust functional validation across all advanced semiconductor products. Key Responsibilities 1. Standard Cell Design & Characterization Leadership Lead the full-flow generation and validation of customized characterization libraries (Liberty, noise, power) for advanced technologies. Characterize and optimize standard cell performance, focusing on key PPA metrics (timing, power, area, and stability) across multiple PVT corners. Utilize industry-standard tools like Siliconsmart and Hspice for transistor-level simulation, model extraction, and quality assurance. Develop and enhance automated Python/Tcl/Shell scripting flows for efficient library characterization and signoff. 2. Digital Implementation and Backend Signoff Execute and manage the Chip Backend Design process (Place & Route, Clock Tree Synthesis, Routing) utilizing tools like Innovus. Perform full signoff closure, including Static Timing Analysis (STA), power integrity checks, and Physical Verification (PV). Implement and analyze chip power data and sensor data extraction to validate Power, Performance, and Area (PPA) goals post-layout. Contribute to successful tape-outs on projects utilizing advanced nodes. 3. Design Verification and Methodology Integration Contribute to functional validation, including FPGA-based verification platforms (Vivado/ISE) and sophisticated simulation methods like XA simulation. Develop and maintain verification environments and scripts using Hardware Description Languages (Verilog/SystemVerilog). Translate characterization and PPA analysis data into improved library usage guidelines and implementation methodologies. How you will stand out: Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related field. 4+ years of direct project experience in the full ASIC flow from design through tape-out on multiple chip projects Demonstrated experience with advanced process nodes (7nm and below) Expert-level knowledge of tools including Siliconsmart, Hspice, Virtuoso, Innovus, and Vivado/ISE. Proficient in automation using Python, Tcl, and Shell. Extensive experience in standard cell library characterization, modeling, and flow development. Strong understanding of the complete digital physical design flow, from RTL to GDSII backend signoff. Familiarity with FPGA verification and digital What you will experience working with us: A culture that values authenticity and diversity of thoughts and backgrounds; An inclusive and respectable environment with open workspaces and an exciting start-up spirit; A fast-growing company with the chance to network with industrial pioneers and enthusiasts; Ability to contribute directly and make an impact on the future of the digital asset industry; Involvement in new projects, developing processes/systems; Personal accountability, autonomy, fast growth, and learning opportunities; Attractive welfare benefits and developmental opportunities such as training and mentoring.
