Job summary

RosaicLabs Inc in Santa Clara, CA is seeking an experienced physical design engineer to own the implementation of accelerator blocks and top level, including synthesis, floorplanning, place-and-route, and clock-tree synthesis.

You will collaborate with architecture, RTL, DFT, and verification teams to optimize for power, timing, and area, and you will develop automation for flows, QoR tracking, and silicon bring-up support.

Qualifications

• Experience in high-performance digital design with synthesis and place-and-route.
• Familiarity with timing closure and multi-corner/multi-mode analysis.
• Experience delivering signoff at advanced process nodes and DRC/LVS knowledge.

Responsibilities

• Own physical implementation of accelerator blocks and top level: synthesis, floorplanning, power planning, placement, clock tree synthesis, and routing.
• Develop floorplans for repeated compute tiles, large SRAM arrays, and high-bandwidth data movement, balancing congestion, wire length, and utilization.
• Close timing, power, and area (PPA) targets, including optimization of datapath-heavy and high-fanout structures.
• Manage power delivery and density: power grid design, IR-drop and electromigration analysis, and thermal-aware implementation.
• Implement low-power techniques such as clock gating, power gating, multi-Vt, and multi-voltage domains.
• Run static timing analysis, signal-integrity, and physical verification (DRC/LVS) signoff across corners and modes.
• Partition and implement hierarchical designs, including budgeting and integration of replicated blocks.
• Work with architecture, RTL, DFT, and verification teams to co-optimize design for physical implementability.
• Develop and maintain automation for flows, regressions, and QoR tracking.
• Support silicon bring-up and correlate post-silicon results with pre-silicon predictions.
