Senior / Staff STA Engineer

Tenstorrent is looking for a skilled and detail-oriented Static Timing Analysis (STA) Engineer to help us deliver first-pass silicon success for our cutting-edge AI and RISC-V SoCs. Engineers with a strong foundation in Static Timing Analysis (STA) and timing constraints . In this role, you’ll lead timing closure efforts across block and full-chip levels, working closely with physical design, RTL, and verification teams across multiple technology nodes, including 5nm and 3nm. This role is onsite, based out of Bangalore.

We welcome candidates at various experience levels for this role. During the interview process, candidates will be assessed for the appropriate level, and offers will align with that level, which may differ from the one in this posting.

Who You Are :

5+ years of hands-on experience in STA for complex SoCs, spanning from block-level to full-chip analysis and closure.

Proven expertise in developing and validating timing constraints (SDF / SDC) for various design modes and PVT corners.

Comfortable using tools like PrimeTime, Tempus , or PTPX for timing signoff and power analysis.

Strong scripting skills in Tcl, Perl, or Python to automate timing flows and custom reporting.

Ability to collaborate across RTL, PD, DFT, and synthesis teams to debug and resolve timing issues efficiently.

What We Need :

Ability to define and own STA methodology , including timing constraints development across different corners and modes (functional, scan, low-power, etc.).

Deep experience in reviewing and maintaining SDC constraints , validating them against design intent, and ensuring completeness and correctness.

Proficient in analyzing timing reports, fixing setup / hold violations, and closing timing at worst-case and best-case corners .

Familiarity with CDC analysis , false / multicycle path constraints, MMMC flows , and timing exception debugging .

Experience handling ECOs for timing and functional fixes, with strong focus on minimizing risk and turnaround time.

What You Will Learn :

Tackle timing closure challenges on advanced nodes (e.g., 5nm, 3nm ), with complex clocking and power architectures.

Collaborate across global teams to deliver high-performance, low-power silicon on aggressive schedules.

Improve and refine STA signoff flows, checklists, and timing constraint coverage metrics .

Develop deep debugging insight by working on real silicon use cases, pushing for first-silicon success .
