Job Description
The Role
SiFive is looking for hardware engineers who are passionate about designing industry-leading CPU and interconnect IP to help drive the tidal wave of adoption of RISC-V as the architecture of choice for SOC designs across a broad variety of vertical applications. We’re creating massively customizable IP and improving time-to-market by designing hardware as highly-configurable generators. We're leveraging technology and ideas from the software industry to execute hardware design with the agility of software development.
As a Power-Management/Reset/Clock Micro-Architect and RTL Design Engineer at SiFive, you will be part of a team of engineers who are passionate about designing industry-leading CPU cores and subsystems based on the revolutionary open RISC-V and TileLink architectures. You will create power management, reset, and clocking solutions that provide the central nervous system for cutting-edge RISC-V CPU and SoC IP designs. You will work in a fast-paced dynamic environment to bring new hardware IP to market quickly, with high quality and exceptional performance - delivering hardware at the speed of software!
