Job Description
The Role: Join the RISC-V revolution as a datacenter system software architect at SiFive. Your responsibilities will involve designing and implementing high-performance RISC-V Linux systems for datacenters, collaborating closely with hardware architects, and engaging with key customers and partners to integrate their functional and performance requirements. You'll also help guide the development of RISC-V software and firmware stacks, participate in RISC-V standards development, and drive the adoption of next-generation server extension cards.
Responsibilities
- Architect systems and system software for hyperscaler deployments based on RISC-V.
- Collaborate with key customers and partners to integrate their functional and performance requirements, understand key workloads, and ensure SiFive systems are well-supported in associated software ecosystems.
- Help guide the development of RISC-V software and firmware stacks for servers, including platform controller firmware, platform firmware, hypervisors, Linux, and application stacks.
- Engage with RISC-V software ecosystem organizations to help guide external development.
- Work with SiFive performance benchmarking and software optimization teams to help identify and resolve bottlenecks limiting the performance of the design.
- Drive the adoption and integration of next-generation server extension cards, involving CXL, RDMA, networking and storage offload, and compute accelerators.
- Participate in planning, estimating, and driving complex software projects.
Requirements
- Experience defining requirements for x86 or ARM servers for hyperscaler use cases.
- Experience with key server requirements including RAS, telemetry, manageability, and I/O offloading.
- Experience with key application workloads, including distributed databases, AI/ML training/inference, agentic AI, and high-throughput microservices.
- 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 with datacenter Linux distributions such as Debian, Red Hat Enterprise Linux, and SLES.
- Strong communication skills.
- Strong project leadership skills, including the ability to develop roadmaps, work breakdowns, and estimates, and drive projects.
Nice to Have
- Experience working with RTL engineers and with RTL product lifecycles.
- Experience with C++ or Rust.
- Experience working in global teams and cross-cultural communication.
