Senior Physical Design Engineer: STA & Timing Convergence

Tenstorrent; Santa Clara (CA); Hybrid; USD 100,000 - 500,000; Full time

Job summary

Tenstorrent is seeking a mid- to senior-level Physical Design Engineer with 8+ years of experience in STA, timing closure, and advanced-node design implementation. Embrace a hybrid role with multiple locations and collaborate across teams to drive tapeout success.

You will write and debug SDC constraints, develop ECOs and closure strategies, and apply Python/Tcl scripting to automate flows while engaging with SPICE/PNR/DFT areas as needed.

Qualifications

• 8+ years of experience in STA, timing closure, and advanced-node design implementation.
• Experienced with timing flows, constraints, clocking, CDC, RDC, derates, uncertainties, guardbanding, and final signoff.
• Skilled in writing and debugging SDC constraints, creating ECOs, developing closure strategies, and analyzing worst-case corners.
• A strong collaborator and communicator who can drive results across distributed, cross-functional engineering teams.

Responsibilities

• Drive timing convergence across blocks, partitions, sections, and top-level designs; generate and validate timing models and publish results.
• Analyze timing violations, develop and propagate fixes, debug timing-flow issues, and keep execution progressing through tapeout.
• Develop and validate bottom-up constraints while partnering with Design and DFT teams on methodology updates and closure requirements.
• Use Python, Perl, and Tcl for automation and flow development; experience with SPICE, PNR, placement, CTS, routing, post-route optimization, DFT, or AI-based automation is a plus.
