Job Title

Senior Design Engineer — CPU Execution Unit

Role Summary

Design and implement the CPU execution unit, focusing on arithmetic/ALU logic and high-speed processor pipeline microarchitectures. Work within the CPU core team to deliver RTL, ensure timing closure, and support low-power, deep-submicron implementations.

Experience Level

Senior. Typical guidance: 5–8 years of relevant ASIC/CPU design experience; exceptional candidates with lower experience may be considered.

Responsibilities

Primary responsibilities include microarchitecture and RTL design, timing closure, and collaboration with verification and physical design teams.

  • Design ALU/arithmetic units and instruction execution datapaths for high-speed pipelines.
  • Develop and deliver RTL (Verilog/SystemVerilog) for execution-stage logic.
  • Work on timing closure and static timing analysis (STA) for deep-submicron designs.
  • Apply low-power design techniques appropriate for advanced process nodes.
  • Address CDC and lint issues, and support synthesis flows toward gate-level implementation.
  • Collaborate with verification, physical design, and system architects to integrate execution unit changes.

Requirements

Must-have technical skills and experience; list of preferred extras follows.

  • 5–8 years of relevant ASIC/processor design experience (flexible for strong candidates).
  • Proven experience with ALU/arithmetic logic design in high-speed processor pipelines.
  • Experience with Verilog/SystemVerilog RTL coding, synthesis flows, and STA.
  • Familiarity with CDC analysis and lint workflows and fixing related issues.
  • Hands-on experience with low-power techniques for deep-submicron technologies.
  • Ability to work effectively with verification and physical design teams toward tapeout.

Nice-to-have:

  • Experience with C and scripting languages (Perl, shell, Python, awk).

Education Requirements

Not specified.
