Senior CPU Microarchitecture & Logic Design Engineer, Execution Unit
​​
Job Description
​

We are seeking a Senior CPU Design Engineer with expertise in execution unit design, including Integer ALUs, floating point units, and SIMD/Vector units. In this role, you will be responsible for designing and implementing high-performance execution units in CPU, optimizing for power, performance, and area (PPA). You will work closely with cross-functional teams to refine microarchitecture, develop RTL, and validate designs.  

This is an opportunity to work on challenging projects and play a key role in defining execution unit architecture for next-generation CPU designs. 

This position is only open to candidates eligible to work in the U.S. (no relocation or visa sponsorship available) and is based in Austin, TX, California, or Portland, OR. 

​

Responsibilities
  • Define, develop, and refine microarchitecture specifications for complex CPU subsystems, with focus on Integer ALUs, Floating Point Units, and SIMD/Vector Units. 

  • Design and implement RTL to achieve targeted power, performance, area, and timing goals. 

  • Collaborate closely with the verification team to establish effective validation strategies for new designs.  

  • Support test bench development and assist validation engineers in testing and debugging core and subsystem-level RTL in simulation, prototyping platforms, and silicon. 

  • Work with physical design teams to ensure that the design meets timing, area, reliability, testability, and power requirements. 

​

Qualifications & Skills:​
  • Minimum Qualifications:​​

    • Bachelor’s degree in Electrical/Computer Engineering, Computer Science, or a related field with 4+ years of experience; OR a Master’s degree with 3+ years of experience; OR a PhD with 1+ years of experience. 

    • Strong understanding of microprocessor architecture and microarchitecture.  

    • Proficiency in applying trade-off and optimization techniques for performance, power, and area (PPA) in high-frequency design. 

    • Experience with SystemVerilog RTL development. 

    • Hands-on experience with front-end tools such as Verilog simulators, waveform viewers, linting tools, logic synthesis, and place-and-route. 

    • Programming skills in C/C++ and Python. 

    • Strong problem-solving skills and an analytical mindset. 

​

  • Preferred Qualifications:​

    • Experience with Integer ALU unit, Floating Point Unit, SIMD and Vector unit. 

    • Expertise in fast multiply and divide algorithms 

    • Familiarity with IEE 754 floating point standard 

    • Experience in execution unit convergence for optimal PPA. 

​​

What We Offer:
  • Competitive salary and benefits package.

  • Opportunities for professional growth in an innovative startup environment.

  • Collaboration with talented engineers passionate about cutting-edge CPU technologies.

  • A flexible and inclusive work culture based in Portland, OR or Austin, TX.
