Job Description:

SiFive is creating RISC-V based CPU IPs faster and cheaper than ever before by combining the best practices of rapid, iterative software design with the proven fidelity of hardware engineering.  State-of-the-art tooling is a critical component of SiFive's success.   We are seeking a season engineering leader to create and deliver a vision of performance simulation tool suite to help SiFive succeed in developing next generation high performance processors as well as enabling customers to use SiFive products

Responsibilities:

• Work with internal and external partners to identify requirements for performance simulation tools 

• Develop a vision and plans to build state-of-the-art tools

• Lead a team of engineers to execute and deliver these tools

Requirements:

• MS or PhD in Computer Science / Computer Architecture

• 10+ years direct industry experience in performance simulation tools - from ISA to SoC / system simulators; from analytical to cycle-based models; from bare-metal environment to virtual machines. 

• 5+ years involved in the engineering team to deliver HW or SW products.

• Strong foundation in computer architecture of high performance out-of-order CPU designs.  Awareness of known industry micro-architectures is a plus.

• Strong foundation in workload characterization to identify HW/SW performance bottlenecks

• Strong foundation in workload reduction techniques for efficient performance simulation and projection 

• Competency in software engineering best practices needed to maintain and refactor very large object oriented code bases.  

• Strong object-oriented programming (OOP) skills, including encapsulation, class coherency, inheritance and polymorphism

• Strong Discrete Event Simulation (DES) competency, particularly with regard to DES modeling techniques and best practices

• Ability to independently analyze performance bottlenecks in micro-architecture and software stack.  Awareness of potential security holes is a plus.

• Desirable: Hands-on expertise with either HW development (RTL/implementation flows, verification/validation, backend flows, FPGA flows) or SW development (C/assembly, OS/RTOS, IDEs, Compiler/Debuggers). 

• Desirable: FPGA debug, including the use of Integrated Logic Analyzer for waveform capture and debug

• Desirable: Familiar with git and branching/forking methodologies
