Originally posted 20 May 2026 by the employer.
Work on floorplan-to-signoff physical design for AI accelerator silicon.
About the role
Own floorplan-to-signoff physical design for one or more blocks of our AI accelerator silicon. This role drives DensityAI's AI accelerator program from first silicon through scale-out.
What you'll do
- Own floorplan-to-signoff physical design for one or more blocks of our AI accelerator silicon
What you'll need
- Exceptional abilities across the full physical design flow (synthesis, place & route, CTS, signoff)
- 8+ years of experience on very high performance designs at advanced technology nodes (7nm or better)
- Hands-on with industry-standard PD tools (Cadence Innovus, Synopsys Fusion Compiler, or equivalent) and signoff (PrimeTime, Tempus, or equivalent)
- Demonstrated ability to work closely with architects, RTL designers, EDA vendors, and foundries to design and sign off complex chips
Nice to have
- Multi-die packaging (CoWoS, 2.5D / 3D), thermal / IR / EM signoff, signal integrity, or DFT-aware physical design
Skills: floorplan-to-signoff, physical design flow, synthesis, place & route, CTS, Cadence Innovus, AI accelerator silicon
