Senior LLVM Compiler Engineer

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, 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 proven 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 workload-focused hardware needed to design next-generation products.

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.

Our LLVM based, world class compiler technology is the backbone of the SiFive software stack that enables SiFive high-performance Linux-capable cores and SiFive Intelligence processors. The compiler team's mission is to deliver cutting-edge performance in SiFive products while working with the community to advance RISC-V architecture and ISA extensions.  SiFive is an active participant in the RISC-V ecosystem that opens a vast opportunity to develop the next generation of computer architecture and compiler technology. SiFive engineers are active members and maintainers in many open source projects, and our mission is to work with and drive the RSIC-V ecosystem.

We are looking for a solid senior LLVM compiler team member with proven experience in compiler technology such as SSA-based global optimizations, auto-vectorization, ISA extensions, and high-performance computing. The candidate should demonstrate a track record in cross-team collaboration and in delivering high quality compiler products. 

Responsibilities:

  • Working with SiFive’s LLVM compiler team in improving performance for the SiFive Intelligence processor family.
  • Working with SiFive’s benchmarking teams in analyzing performance results and suggesting new compiler optimizations.
  • Working with SiFive’s compiler and release teams in releasing timely compiler toolchains for use by SiFive software and hardware teams.

Requirements:

  • 3+ years of experience in compiler technology.
  • Degree in computer science or engineering.
  • Experience with open source contributions. 
  • Experience with hardware specific optimizations such as SIMD or other specialized accelerators.
SiFive is proud to be an equal employment opportunity workplace. We offer a competitive compensation package that includes flexible paid time off; health, vision and dental benefits; 401(k) plan; employee stock option program, and much more.
We will ensure that individuals with disabilities are provided reasonable accommodation to participate in the job application or interview process, to perform essential job functions, and to receive other benefits and privileges of employment. Please contact us to request accommodation.
