SoC Architect (Flexible location worldwide)

About SiFive
SiFive is an idea-to-silicon company founded by the inventors of RISC-V to simplify the design and production of custom SoCs.
As the leading commercial provider of RISC-V processor IP & SoC IP, SiFive is on a mission to help engineers design custom chips for domain-specific solutions for many markets, including 5G, edge AI, enterprise networking, storage, and consumer devices.
Industry-leading innovators, including six of the top ten semiconductor companies, are working with SiFive thanks to our shown success, deep expertise, and rich partner ecosystem. With SiFive’s rich IP ecosystem and accessible design platform, every market has access to the development of domain-specific hardware needed to design next-generation products.
SiFive was founded and is actively run by the developers of RISC-V. If you are passionate about working with industry leaders and innovators, then send us your application today!
As a SoC Architect at SiFive, you will be vital to SiFive's efforts to create silicon at the speed of software. You will create the basic collateral and specifications that can be reused across the SoC design ecosystem. In developing this collateral, you have the opportunity to innovate the use of a novel set of electronic design automation (EDA) tools, which will draw on modern compiling technology and other innovations to build SiFive’s SoC and core libraries.
The new SoC Architect will create and build new, highly configurable SoC designs, based on the open-specification RISC-V ISA for SiFive’s clients, who are taking on exciting state-of-the-art use cases such as autonomous driving, 5G, networking, wearables, or IoT. You will have a chance to define and design chips more quickly and for more devices than would be technologically possible at any other company. 
We are reducing the time needed for chip design and verification with novel tools and methodologies, and we are looking for an architect who is as excited as we are about bringing new SoC designs to the market!
LOCATION: The ideal candidate for this position can work out of any of the SiFive worldwide offices in the US, France, India, or Taiwan.
