Senior System Architect

Fractile is building silicon, systems and software which will redefine the frontier of AI: running the world’s most advanced models at radically higher speed and lower cost. We have an exceptional team across hardware and software capable of bringing about this change, and we are growing fast to meet demand and deliver our product at scale. Senior System Architect, you’ll define and drive the end-to-end hardware architecture that underpins our products from chip-level interfaces and interconnects through to board design, thermal management, and system-level integration. This isn’t just about designing elegant systems on paper. You’ll work closely with digital, and verification teams to translate architecture into working silicon and reliable hardware platforms. Expect to be hands-on in early prototyping, bring-up, and system testing. You’ll be the connective tissue between hardware, firmware, and software, ensuring architectural coherence and technical excellence across all layers. Key Responsibilities Define and own the system architecture roadmap, balancing performance, power, and scalability. Contribute to system-level design from concept through production, coordinating with chip design, mechanical, and manufacturing teams. Specify system interfaces, power delivery networks, interconnects, and control subsystems. Guide board and platform design for early bring-up and validation. Partner with the software and firmware leads to ensure seamless integration and coherent system-level performance.
