ASIC Engineer, Implementation - Timing

Meta's Infrastructure Silicon team is seeking an ASIC Implementation Engineer specializing in timing to help design and deliver custom silicon for data center applications. In this role, you will drive static timing analysis and timing closure across complex System on Chip designs, working at the intersection of front-end and back-end implementation to ensure our infrastructure chips meet performance, power, and area targets at advanced process nodes.

Responsibilities

Develop and maintain timing constraints (SDC) for complex SoC designs, including clock definitions, input/output delays, multicycle paths, and false paths
Perform static timing analysis using industry-standard sign-off tools to identify and resolve setup, hold, and clock skew violations across hierarchical design blocks
Drive timing closure through collaboration with physical design engineers, providing guidance on placement, routing, and clock tree synthesis to meet timing targets
Analyze and debug timing paths across multiple clock domains, identifying critical paths and recommending RTL or physical implementation optimizations
Generate and validate timing reports for sign-off across process, voltage, and temperature corners, including on-chip variation analysis
Develop and maintain timing exception methodologies and waiver processes in coordination with design and verification teams
Contribute to the development and improvement of timing closure scripts and automation flows using scripting languages to increase efficiency and repeatability
Interface with foundry and library teams to characterize and integrate timing libraries, including standard cells, memories, and hard IP
Support design handoff between front-end and back-end teams by providing timing-aware synthesis netlists and constraint validation
