Job Description:

Senior/Staff CPU Physical Design Engineer – High-Performance Compute / Semiconductors

We are partnered with a global leader in semiconductor and wireless technology innovation. The team is looking to hire a Senior or Staff Server CPU Physical Design Engineer to own block-level physical implementation for next-generation, high-performance custom CPU cores targeting advanced compute and server-class platforms.

This is a permanent, fully onsite opportunity based in Cambridge, UK.

Key responsibilities for this CPU Physical Design Engineer position:

  • Own or contribute to CPU block implementation from RTL/netlist to GDS
  • Drive timing closure and physical implementation convergence across multiple modes, corners, and operating conditions.
  • Debug and resolve complex implementation issues across timing, congestion, clocking, IR drop, power integrity, EM, and DRC/LVS.
  • Collaborate with RTL, architecture, circuits, CAD, SoC, and post-silicon teams to improve design quality and PPA.
  • Develop and enhance physical design flows, automation, and methodologies.

Key requirements:

  • Strong experience in physical design — synthesis, floorplanning, placement, CTS, routing, timing closure, ECOs, and signoff.
  • Solid understanding of STA and timing closure methodologies, including PPA trade-offs.
  • Hands-on experience with industry-standard EDA tools — Genus, Innovus, Fusion Compiler, PrimeTime, Tempus, Voltus, RedHawk, or equivalent.
  • Scripting experience in TCL, Python, or Perl.
  • Experience on CPU cores, advanced nodes (7nm and below), or low-power design techniques advantageous.
