  • Be Fearless: Unmute yourself. Test boundaries and get proven right.
  • Remain Adaptable: Stay comfortable in a continuously changing world. If you're wrong, concede and move on.
  • Educate Your Ego: Selflessly collaborate towards our shared purpose.

About the role:
We're looking for an experienced GPU Driver Developer. You will focus the design, development, implementation, and toolchain of a high-performance host-side driver stack and API for our proprietary RISC-V GPU architecture.
We are looking to fill a range of Junior to Senior roles.
What you'll do:
  • Focus on the design of a low-level path-tracing, graphics, and compute API for our proprietary GPU
  • Play a key role in the development of User & Kernel Mode Drivers that can be executed on a host CPU running Windows or Linux, or embedded on a RISC-V CPU running Linux
  • Coordinate with the GPU Compiler team to communicate with the GPU through PCIe or on-board shared memory
  • Coordinate with the GPU Standards Development team to implement functionality required by industry standard APIs that overlay our proprietary GPU driver
  • Develop a toolchain for development, optimization, and debugging

Qualifications:
  • Bachelor's/Master's degree in Computer Engineering, Computer Science, or related field
  • Industry experience with high-performance graphics and compute drivers
  • Experience developing drivers for Windows and Linux

  • Experience with code analysis, IR (LLVM, MLIR, ISPC), and LLVM and GCC internals
  • Demonstrated ability to ship high-quality production software

Preferred Qualifications:
  • Understanding and experience with RISC-V and vector processors
  • Experience with PCIe bus communications
  • Experience co-designing hardware architectures
  • Understanding of path and ray tracing

Compensation Range: $175,000-$250,000 per year (California). This range represents the anticipated base pay for this role; the final offer may vary based on qualifications, experience, and location.
Benefits:
  • Medical, Dental, & Vision - 100% covered premiums
