STA Engineer

Job Title: Static Timing Analysis (STA) Engineer

Job Overview

We are looking for a highly skilled Static Timing Analysis (STA) Engineer to join our ASIC/SoC design team. The ideal candidate will be responsible for performing timing analysis, developing constraints, and driving timing closure across multiple design stages. This role requires strong technical expertise, problem-solving skills, and cross-functional collaboration.

Key Responsibilities

• Perform Static Timing Analysis (setup, hold, recovery, removal) across all PVT corners and modes.
• Create, refine, and validate SDC constraints including clocks, generated clocks, false paths, and multi-cycle paths.
• Drive timing closure during synthesis, place & route, and final signoff.
• Debug timing violations related to clocking, logic depth, routing, buffering, and cell sizing.
• Work closely with RTL, Physical Design, CTS, and DFT teams to resolve timing issues.
• Run STA using tools such as Synopsys PrimeTime or Cadence Tempus.
• Analyze SI/crosstalk, OCV/AOCV/POCV, and apply advanced timing methodologies.
• Ensure full timing signoff criteria are met before tape-out.

Required Qualifications

• 310 years of hands-on STA experience (can adjust based on your needs).
• Bachelor's or Master's in Electrical Engineering, Electronics, VLSI, or related field.
• Strong understanding of digital logic, timing concepts, and CMOS fundamentals.
• Experience with PrimeTime, Tempus, ICC2, Fusion Compiler, or Innovus.
• Solid knowledge of SDC, timing exceptions, and multi-clock domain analysis.
• Proficiency in Tcl, with additional scripting (Python/Perl) being a plus.

Preferred Skills

• Experience with SoC-level STA and hierarchical timing flows.
• Knowledge of clock tree synthesis (CTS) and clock architecture.
• Familiarity with low-power design (UPF/CPF).
• Understanding of DFT timing, scan modes, and test constraints.

Soft Skills

• Strong analytical and debugging abilities.
• Excellent communication and documentation skills.
• Ability to work in a fast-paced, cross-functional environment.
