About this role
We're a fast-moving, US-Israeli AI startup building next-generation infrastructure for the world's most demanding AI workloads. Our mission is to accelerate the future of intelligence and make it ubiquitously accessible by delivering full stack custom AI servers optimized for large-scale inference and training. Backed by top-tier investors and led by industry veterans, we're scaling rapidly. We seek forward-thinking engineers and operators who thrive in a collaborative environment and excel at solving complex challenges from first principles. If you want to build infrastructure that fundamentally changes what the world can accomplish with AI, come join us! About the position We are seeking an experienced SoC Architect - AI Acceleration (RISC-V and Compute Cluster Development) to lead the architecture and integration of Majestic's compute subsystem. In this role, you will define and optimize the RISC-V-based compute clusters, vector engines, and shared memory structures that power high-performance AI workloads. You'll collaborate closely with design, verification, compiler, and ML software teams to define architectures that maximize performance per watt while ensuring scalability across multiple generations of silicon. This is a hands-on technical leadership role for an architect who thrives at the intersection of hardware design, parallel compute, and AI acceleration. Responsibilities Architect and define RISC-V compute clusters, including multi-core integration, interconnects, and memory subsystems. Design matrix multiplication and vector processing engines optimized for neural network and ML kernels. Define the ISA extensions, microarchitecture, and system-level interfaces supporting AI acceleration. Develop strategies for compute task mapping, thread scheduling,...
