Job Description:

Sr. Staff System and Software Architect

The Role:

Do you want to be part of the RISC-V revolution? RISC-V and SiFive are redefining computing platforms for the 21st century. As a System and Software Architect, you’ll play a leading role in designing and implementing these platforms, spanning software and hardware architecture and engineering.

In this position, you’ll play a key role in designing and evaluating RISC-V computing systems. Unlike in many larger companies, SiFive engineers can work cross-functionally, with full access to our software and hardware codebases.

The home for this role is in SiFive’s Software Engineering group, architecting and writing software that takes advantage of SiFive and RISC-V hardware features and integrates cleanly with existing operating systems, primarily Linux. You’ll help author and review architecture specifications for new hardware and software features. You’ll engage with key industry organizations, like RISC-V International and RISE. You’ll be a part of creating something big - all based around the RISC-V instruction set architecture.

Responsibilities:

• Work with multiple global engineering teams to architect, design, implement and deliver advanced CPU cores, subsystems, SoCs, and IP subsystems with emphasis on scalability, performance, reliability, and support of new hardware technologies.

• Utilize your experience to create solutions to key architectural challenges for modern, high-level systems.

• Design and help develop SiFive and RISC-V software.

• Collaborate cross-functionally to help plan how to test key features in complex system environments.

Requirements:

• Experience developing low level code in C for multiprocessor, multithreaded operating systems such as the Linux kernel, BSD kernels, or other high level operating systems (HLOS)

• Understanding of computer architecture at the CPU and system levels, VLSI design concepts and how they impact hardware and software architecture

• Experience writing and reviewing architecture specifications, both for hardware and software

• Experience with modern desktop and server ecosystems, including PCIe, Device Tree, ACPI, and UEFI.

• Experience with the RISC-V ISA and RISC-V software ecosystem.

• Experience working with RTL engineers and with RTL product lifecycles.

• Good communication skills.

Nice to have:

• Experience with accelerated computing software and hardware stacks.

• Experience with Linux distributions or distribution builders such as Debian, Red Hat Enterprise Linux, SLES, and Yocto.

• Experience with C++, Rust, or SPARK/ADA.

• Experience working in global teams and cross-cultural communication.

• Experience with virtualization and device passthrough workloads.
