CPU Custom Library and Memory Layout Lead
NUVACORE
Designs high-performance, general-purpose CPU cores
Salary Range: 200000 to 300000 (Currency: USD) (Pay period: per-year-salary)
At NUVACORE we're designing a new general-purpose CPU core for the sustained, intensive demands of AI infrastructure and agentic computing, not the workloads of the past. As a member of the CPU-specific custom circuit design team, you will enable the design to achieve the target PPA specifications for the product.
As a Custom Library and Memory Layout Lead, you will participate in the following :
Lead physical layout of custom library cells (flip-flops, clock-gating cells, level shifters, AOI cells) and custom memory arrays (bit cell arrays, sense amps, decoders, register files) at advanced process nodes - own layout prototyping of critical cells.
Own end-to-end layout closure: floorplanning, logic/SRAM place-and-route, DRC/LVS/antenna clean-up, parasitic extraction hand-off, and mitigation of layout-dependent effects (LDE).
Partner with circuit design, Foundry/PDK, CAD, and DFT teams to co-optimize layout for PPA, manufacturability, and yield; validate IP on testchips.
Define and drive layout methodology and automation — including P-cell/script-based layout generation and DRC/LVS regression — to raise design efficiency and set team-wide best practices.
Manage layout vendors and contractors to scale layout execution across macro designs and cells — scoping work packages, setting quality/schedule targets, and reviewing deliverables for PPA, DRC/LVS, and methodology compliance.
Hold a BS or MS degree with 12+ years of experience in custom/standard-cell and/or memory layout at advanced CMOS nodes.
Hands-on transistor-level layout experience with static circuits and state-retaining elements (latches, flops), as well as memory arrays — bit cells, sense amps, decoders — at advanced CMOS nodes.
Deep knowledge of DRC/LVS/antenna rules, parasitic extraction, and layout-versus-schematic closure using industry-standard EDA tools (e.g. Virtuoso, Calibre, StarRC).
Strong understanding of layout-dependent effects, matching and symmetry techniques, and their impact on circuit PPA and variation.
Experience providing layout-driven feedback to foundry partners on PPA, yield, and DRC/PDK improvements.
Strong communication and collaboration skills, comfortable working directly with circuit design, foundry, and CAD partner teams.
Relevant hands-on experience laying out designs in cutting-edge process technologies, preferably Gate-All-Around (GAA) nodes.
Experience across the full custom layout flow — floorplanning, cell/bit-cell layout, P-cell/script-based automation, DRC/LVS signoff, and extraction hand-off.
Proficient in SKILL, Python, or Tcl to build and improve layout automation and DRC/LVS regression flows.
Track record delivering production-level standard cell and/or memory layouts through tape-out, with silicon-validated PPA in high-volume products.
Experience with testchip layout development and DTCO partnering with foundries at leading-edge nodes.
Experience managing external layout vendors/contractors — work scoping, quality/schedule tracking, and technical review — to scale capacity across macro and cell layout programs.
Experience using Agentic AI tools for productivity and automation.
Nuvacore designs high-performance, general-purpose CPU cores built from the ground up to meet AI-focused workloads in data centers and advanced systems. It offers cores as either IP for chip developers or finished chips, optimized for speed and area efficiency to handle continuous, long-running tasks. The team combines veterans from Nuvia, Apple, and Arm, focusing on agentic computing rather than specialized accelerators to differentiate from competitors. The goal is to deliver scalable, reliable CPUs that provide high throughput for large-scale AI workloads and continuous computing tasks.
