Senior Digital Design Engineer

Senior Digital Design Engineer****Summary

Smart Silicon is seeking a Senior Digital Design Engineer with RTL design experience to own the design of low-power, multi-clock-domain digital blocks. You will take blocks from specification through RTL, synthesis and sign-off support, and act as a technical reference for the engineers around you.

Responsibilities

• Write block specifications based on the system architecture and requirements
• Contribute to microarchitecture definition and architecture refinement; take an active role in design reviews
• Develop low-power RTL in SystemVerilog/VHDL and integrate blocks at system level, with strong emphasis on low-power synchronous design techniques and area reduction
• Optimize designs for power, area, timing and maintainability
• Work closely with verification: define corner cases and test scenarios, debug blocks, and drive coverage closure
• Synthesize blocks, including SDC authoring, and work with the backend team through timing closure
• Run and debug Lint, CDC and Formality logical equivalence checks through to sign-off
• Mentor and review the work of junior engineers

Qualifications

• B.Sc./M.Sc/P.hD. in Electrical or Computer Engineering (or equivalent)

• 5–7+ years of digital ASIC RTL design in SystemVerilog and/or VHDL

• Proven low-power design experience: clock gating, operand isolation, power gating, retention/isolation strategies, UPF/power intent

• Solid multi-clock-domain design: CDC schemes, synchronizers, reset strategy

• Tape-out experience with knowledge of RTL to GDS flow

• Hands on experience in defining constraints for Synthesis and ability to understand timing & power reports

• Hands-on sign-off checks: Lint and CDC, LEC

• Experience in writing specifications and presenting in design reviews

• Scripting (Python, Tcl, Bash/Perl); version control (Git, Perforce)

• Nice to have:

  functional safety (e.g. ISO 26262), mixed-signal controller design, DFT awareness

Soft Skills

• Clear written and spoken English, especially in specifications and reviews
• Ownership: you drive your block's issues to closure
• Willingness to guide and support junior colleagues
