Bengaluru, India Tenstorrent Full time

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
    .
