Job Description:

You will be joining SiFive’s FireSim team, which develops an internal, FPGA-based hardware emulation tool forked from the open-source FireSim project.  Here you’ll get the opportunity to develop both emulator hardware (FPGA RTL) and runtime software (Scala, C++) to facilitate high-speed verification and validation of SiFive’s RISC-V processor IP.  This is a multi-disciplinary team with projects available to students studying digital design, compiler development, and software engineering. 

Undergraduate applicants will work within a specific subsystem of FireSim according to their engineering preferences and career goals (e.g.: more compiler oriented students may work on CIRCT). Graduate students will have the opportunity to define a hardware emulation-oriented research project that can slot within the FireSim ecosystem.

• Report to the FireSim team in Berkeley, three days a week

• Core technical responsibilities include subset of:

  Developing compiler passes in our CIRCT-based emulation compiler

  Designing new emulator features using both Chisel and C++

• Add robust tests for newly designed features

• Help maintain CI / CD systems related to their subsystem

• Help rollout new agentic processes to augment emulator subsystems, where appropriate

• Be enrolled in a Bachelor’s, Master’s, or PhD program in Computer Science, Computer Engineering, or Electrical Engineering

• Hardware-oriented students should have:

  Exposure to RTL design, using Chisel or Verilog

  Exposure to design for FPGA

• Software-oriented students should have:

  experience writing performance-optimized C or C++ code

  experience developing within LLVM, or CIRCT projects

• A combination of both would be ideal

• Strong communication and interpersonal skills and a desire to develop them that matches their desire to do technical work

If you want to do incredible work and be challenged by exciting, truly innovative projects that will test the boundaries of your skills and creativity, then SiFive is the place for you!  Be proud of your work.  Do things better.  Join SiFive.
