Job Title

Physical Design Engineer (PnR)

About The Role

Avicena is developing high-speed parallel optical links built from arrays of microLED transmitters and photodetector receivers. We are looking for a physical design engineer to implement and close digital blocks and top-level partitions of our mixed-signal ASIC. You will work with the PnR lead to take designs from netlist to clean signoff.

Key Responsibilities

  • Run synthesis, floorplanning, placement, clock tree synthesis and routing for blocks and partitions.
  • Close timing across modes and corners, and implement ECOs.
  • Run signoff checks: STA, IR drop and EM, physical verification and logical equivalence.
  • Integrate analog macros and repeated arrays following the macro handoff checklist.
  • Maintain and improve implementation scripts.
  • Support tapeout and post-tapeout ECOs.

Qualifications

Required

  • BS or MS in Electrical or Computer Engineering with 3+ years of ASIC physical design.
  • Hands-on experience with Cadence Innovus or Synopsys ICC2/Fusion Compiler, and STA with Tempus or PrimeTime.
  • Physical verification with Calibre or Pegasus.
  • FinFET implementation experience.
  • Tcl and Python scripting.

Preferred

  • Mixed-signal top-level integration.
  • IR/EM analysis and fixing.
  • DFT-aware implementation, such as scan chain reordering.
  • Hierarchical implementation.

Key Competencies

  • Detail-oriented: closes issues completely.
  • Learner: picks up new flows quickly.
  • Collaboration: works closely with the PnR lead and design teams.
  • Ownership: delivers assigned blocks on schedule.
