Senior System Architect

Senior System Architect Overview

Fractile is at the forefront of developing silicon, systems, and software aimed at revolutionizing AI capabilities by enabling the execution of advanced models at unprecedented speeds and reduced costs. Our dynamic team, which spans hardware and software, is rapidly expanding to meet the growing demand for our innovative products.

As a Senior System Architect, you will be responsible for defining and driving the comprehensive hardware architecture that supports our products. This includes everything from chip-level interfaces and interconnects to board design, thermal management, and system-level integration. Your role will involve close collaboration with digital and verification teams to translate architectural designs into functional silicon and reliable hardware platforms. You will also engage in hands-on activities during early prototyping, bring-up, and system testing, acting as a crucial link between hardware, firmware, and software to ensure architectural coherence and technical excellence.

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 software and firmware leads to ensure seamless integration and coherent system-level performance.
• Evaluate emerging technologies and components to inform architectural decisions.
• Act as a technical mentor, raising the bar for design discipline and documentation across the team.
• Represent system architecture in technical reviews, partner discussions, and customer engagements.

Skills & Experience

• Proven experience as a Systems Architect, SoC Architect, or similar role in semiconductor or high-performance computing domains.
• Deep understanding of system-level design, including power, thermal, I/O, memory, and interconnect architectures.
• Strong grasp of digital design flows.
• Experience taking complex hardware systems from concept through to mass production.
• Demonstrated ability to define and manage system requirements and trade-offs.
• Comfortable working across many disciplines, hardware, firmware, and software.
• Excellent communicator who can bridge technical depth with practical execution.

Desirable

• Background in AI acceleration, HPC, or data-centric architectures.
• Experience with FPGA prototyping and system bring-up.
• Familiarity with modern toolchains and modelling environments (SystemC, MATLAB, etc.).
• Prior start-up or scale-up experience, thriving in ambiguity and fast iteration.
