We aspire to create products (SoCs, Software, Power and Analog chips etc) which serve needs for local market. Renesas is a leading electronics supplier globally, and this is a unique opportunity to directly influence the future products which will be offered to our customers in a new, fast growing and large Indian market with specific needs and applications. Senior/Staff STA (Static Timing Analysis) Engineer  The STA Engineer is responsible for ensuring robust timing closure and signoff readiness for block- and full-chip designs across all modes and corners. This role owns timing constraint development and validation, performs detailed setup/hold and variation-aware analysis, and partners closely with Synthesis, CTS, Physical Design, and Design teams to debug violations and drive ECO-based optimizations through tapeout.  What you’ll do  - Perform full-chip and block-level Static Timing Analysis (STA) across all modes and corners.  - Analyze and debug setup, hold, recovery, removal, clock gating, and signal integrity-related timing violations.  - Work closely with Physical Design, Synthesis, CTS, and Design teams to achieve timing closure.  - Develop and maintain timing constraints including SDC creation, validation, and signoff readiness.  - Drive timing closure through ECO implementation and timing optimization.  - Analyze timing impact due to process, voltage, and temperature variations.  - Support timing signoff for pre-layout and post-layout stages.  - Perform cross-functional reviews for timing convergence and provide recommendations.  - Generate timing reports and communicate closure status to project stakeholders.  What we’re looking for  - 4–12 years of experience in Static Timing Analysis (STA) and timing closure for block and/or full-chip designs.  - Strong understanding of CMOS fundamentals, timing concepts, and semiconductor design flow.  - Hands-on experience in setup/hold analysis, path-based analysis, OCV/AOCV/POCV, derates, and MMMC concepts.  - Good understanding of clock tree, clock uncertainty, latency, skew, and jitter.  - Experience in timing constraints development and debugging.  - Strong knowledge of SDC, timing exceptions, false paths, multicycle paths, and case analysis.  - Familiarity with timing closure techniques and ECO methodologies.  - Hands-on experience with industry-standard STA tools such as Synopsys PrimeTime or Cadence Tempus.  - Good scripting skills in Tcl, Perl, or Python.  - Ability to analyze and resolve timing violations independently. Nice to have  - Exposure to low-power timing analysis and UPF/CPF-aware STA.  - Familiarity with SI-aware timing, Crosstalk analysis, and IR-drop-aware timing closure.  - Knowledge of advanced technology nodes and variation-aware signoff methodologies.  - Exposure to automation and flow development.  - Experience in cross-functional collaboration with PD, RTL, and Signoff teams.  Renesas is an embedded semiconductor solution provider driven by its Purpose, To Make Our Lives Easier.
