Lead SoC Architect 2

Nuvacore is building a new general-purpose CPU core for AI-era, data-center-scale workloads. Founded by veteran CPU and system architects from world-class companies and backed by Sequoia Capital, we're a clean-sheet build with no legacy architecture to carry forward.

THE ROLE
 
We're looking for a Lead SoC Architect to own the SoC architecture surrounding our CPU core — fabric, memory, I/O, power, and security. You'll set architectural direction, make the system-level trade-offs, and work across design, verification, physical design, and software to see them through.

We're building deliberately, with one goal in mind: assembling the team capable of redefining what's possible in silicon.

Think you're one of them?

We're hiring across engineering and technical leadership.

The next great CPU won't build itself.

WHAT YOU WILL OWN
Own the overall SoC architecture: processor complex integration, fabric topology, system level cache hierarchy, I/O, power management, and memory subsystem.
Architect the coherent fabric — interconnect/NoC topology, home node design and placement, snoop filtering, and cache coherency protocol (e.g., CHI/ACE-class) — balancing bandwidth, latency, and QoS.
Size, partition, and place system-level caches and determine their interaction with the fabric and home nodes.
Architect the I/O subsystem: PCIe and CXL controller integration and topology.
Drive memory subsystem architecture: DDR5/DDR6 and LPDDR5/LPDDR6 controller design, interleaving, and DRAM QoS/scheduling.
Establish System MMU (SMMU) architecture and I/O virtualization/translation strategy.
Architect die-to-die interconnect and chiplet partitioning for multi-die configurations (e.g., UCIe-class links).
Select, integrate, and evaluate in-house and third-party IP across the SoC, driving customization with vendors or internal IP teams as needed.
Partner with physical design and packaging teams on floorplan, 2.5D/3D packaging, and power/thermal trade-offs.
Provide top down vision/strategy and stay closely aligned with power architecture and management (clocking, reset, power states) and security architecture (domain isolation, secure boot, hardware trust boundaries), even where dedicated teams own execution.
Author and own architecture specs; drive reviews to closure with design, verification, and software.
Review downstream RTL, verification plans, and software/firmware interfaces against the spec.
Support silicon bring-up and post-silicon debug.
Mentor architects and engineers; represent SoC architecture in cross-functional discussions.
