Staff Implementation Design Engineer

Job Title

Staff Implementation Design Engineer

Role Summary

Staff-level technical contributor on a digital engineering team delivering back-end physical implementation and signoff for highly integrated mixed-signal SoCs used in IoT products. Work covers block- and chip-level implementation through manufacturing, including maintaining and enhancing place-and-route (PnR) flows.

Experience Level

Senior / Staff-level. Years of experience not specified.

Responsibilities

The role focuses on back-end implementation, signoff, and flow maintenance. Key responsibilities include:

• Block- and chip-level floorplanning, pre-wire and timing optimization.
• Data preparation for IP, including analog and RF macros.
• Place-and-route for block macros and full-chip: timing-driven placement/routing, clock-tree synthesis, power routing.
• Timing closure and signoff static timing analysis (STA).
• Parasitic extraction and generation of detailed parasitic data.
• Static and dynamic power/rail analysis and signal-integrity analysis.
• Physical verification including LVS and DRC; implement physical ECOs.
• Maintain and develop PnR flows and evaluate new tools and flow features.
• Apply design-for-yield and design-for-test techniques during implementation.

Requirements

Must-have skills and experience:

• Strong knowledge of IC design flow and SoC/ASIC back-end implementation (synthesis, floorplanning, CTS, power planning, PnR, timing-driven routing).
• Proficient scripting ability (Tcl, Perl, Python) to maintain and develop implementation flows.
• Experience with parasitic generation, STA signoff, signal integrity analysis, and power/rail analysis.
• Advanced knowledge of low-power design flows (voltage/power domains, power shutoff, retention) and CMOS fabrication processes.
• Understanding of design-for-test techniques (scan insertion, ATPG, memory BIST, JTAG).
• Excellent written and verbal communication; able to explain technical concepts to senior leaders.

Nice-to-have:

• Familiarity with quality systems and formal procedures.
• Experience evaluating implementation tools and developing new flow features.
• Prior work on highly integrated mixed-signal SoCs or IoT product platforms.

Education Requirements

MS in Electrical Engineering, or equivalent (degree or equivalent practical experience).
