SoC Management Subsystem Architect

Majestic Labs • Los Altos, CA

3d

About The Position

We are looking for a seasoned SoC Architect to lead the design and integration of the management subsystem within Majestic’s AI acceleration platform. In this role, you will define and drive SoC-level architecture for control and management flows — integrating ARM cores, interconnects, high-speed IO, and system management interfaces. You’ll collaborate closely with peer architects, hardware, firmware, and system engineers to ensure a cohesive, high-performance design that bridges silicon and software seamlessly. This is a hands-on architecture role that combines technical depth, system-level thinking, and cross-domain leadership in a fast-moving startup environment.

Requirements

• Bachelor’s or Master’s in Electrical Engineering, Computer Engineering, or related field.
• 6+ years of experience in SoC architecture and design, with emphasis on management or control subsystems.
• Proven experience with ARM core integration, PCIe, DDR/LPDDR, and peripheral interfaces (SPI, I2C, UART).
• Strong understanding of SoC design flows, memory hierarchy, and interconnect fabrics.
• Hands-on experience in control path design, driver interfaces, and interrupt management.
• Solid communication and teamwork skills, with the ability to lead cross-functional architectural discussions.

Nice To Haves

• Experience with AI/ML acceleration hardware or high-performance compute SoCs.
• Knowledge of board-level integration and hardware-software co-validation.
• Familiarity with silicon prototyping, emulation, or FPGA-based validation.
• Expertise in low-power design and high-bandwidth interconnect architectures.
• Deep experience with debug tools (CoreSight, trace analyzers, profilers) and performance instrumentation.

Responsibilities

• Define and own the management subsystem architecture for Majestic’s AI SoC.
• Integrate ARM cores (CSS / Cortex-A) and associated subsystems for control, configuration, and monitoring.
• Architect PCIe connectivity and high-bandwidth IO to ensure robust host and device communication.
• Specify and integrate DDR/LPDDR interfaces and memory management structures.
• Design peripheral and control interfaces, including SPI, I2C, UART, GPIO, and system control buses.
• Develop scheduler and interrupt schemes, driver-facing control paths, and configuration frameworks.
• Integrate and optimize debug and trace infrastructures (CoreSight, profilers, diagnostic tools).
• Collaborate with RTL, verification, firmware, and board teams to ensure seamless hardware-software co-design.
• Drive tradeoffs and decisions to achieve performance, power, and area targets across the SoC.
