FULL -TIME

- Multiple Levels

- US / Canada / India/Remote 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.

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.

WHAT WE'RE LOOKING FOR

- 20+ years in SoC or system architecture, from definition through tape-out and production.

- Deep expertise in coherent/non-coherent interconnect and fabric architecture, home node design, and coherency protocols.

- Strong grounding in cache hierarchies and memory controller design (DDR5/DDR6, LPDDR5/LPDDR6).

- Working knowledge of PCIe/CXL I/O architecture and System MMU/IO virtualization.

- Experience with die-to-die interconnect and chiplet-based partitioning.

- Track record integrating in-house and third-party IP, including direct work with vendors and internal IP teams.

- Working knowledge of physical design constraints (floorplan, packaging, power delivery, thermal) and their architectural impact.

- Working knowledge of power architecture/management and security architecture at the SoC level.

- Demonstrated ability to lead architecture definition across a matrixed organization.

- Robust written and verbal communication.

- MS or PhD in Electrical Engineering, Computer Engineering, Computer Science, or related field, or equivalent experience.

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
