The Role: We at SiFive are proud to take a software first approach to develop tools and frameworks that achieve cutting edge performance without compromising quality for the SiFive Intelligence processor family. The SiFive Intelligence processors deliver AI acceleration for the edge and beyond. SiFive intelligence builds on RISC-V Vectors (RVV) allowing SiFive to design Core IPs that deliver performance, are optimized for power and area, but do not sacrifice flexibility or programmability. Our software stack is codesigned with the hardware and developed with scalability and quality in mind. Join us to develop revolutionary software from the ground up! SiFive is seeking an experienced System Software Engineer for our System Software group. The SiFive System Software group develops critical software components for our Core and Intelligence processors, from firmware and bare-metal to high-level OS and AI runtime code. The team is global, spanning several worldwide sites, working together as one group. We believe that engineers create most of the value in the company. Our management chain has a strong engineering and software development background. We believe in open, honest, and direct communication; mutual respect; and seek strong communicators and listeners. As a System Software Engineer, you will work with system architecture and hardware engineering teams to help design and evaluate systems, including CPUs, interconnects, firewalls, and related IP blocks. You’ll work with our software group to design software implementations that take advantage of hardware features and integrate cleanly with existing operating systems, such as Linux. You’ll write software for Linux kernel, device drivers, OpenSBI, u-boot, Yocto/OpenEmbedded. You’ll be a part of creating something big, all based around the RISC-V instruction set architecture. Responsibilities: - Design, develop, upstream and release system software: Linux kernel, device drivers, OpenSBI, u-boot, Yocto/OpenEmbedded (both SiFive-proprietary and public open source) - Engage with architecture, hardware engineering, and other software engineering teams to review, and refine features

The Role: SiFive is proud to take a software-first approach to develop tools and frameworks that achieve cutting-edge performance without compromising quality. SiFive's Intelligence processors leverage and extend RISC-V Vectors to accelerate AI applications for the edge and beyond. Our Core IPs navigate tradeoffs between performance, power, and area, but do not sacrifice flexibility or programmability. Our software stack is co-designed with the hardware and developed with scalability and quality in mind. Join us to create revolutionary software from the ground up. As a QEMU Engineer on the System Software Team, you will collaborate with system architecture and hardware engineering teams to design software models and evaluate systems, including CPUs and related IP blocks. You’ll develop software for QEMU to model IP and instruction sets. You’ll be a part of creating something big, all based on the RISC-V instruction set architecture. Responsibilities: - Design, develop, and upstream QEMU and other simulation solutions (both SiFive-proprietary and public open source). - Enhance and maintain existing QEMU RISC-V CPU and SiFive-proprietary peripheral models. - Collaborate with architecture, hardware engineering, and other software engineering teams to review and refine features.
