Principal Engineer, STA & Synthesis

Job Description

We are seeking a Principal Engineer – Implementation Lead to own synthesis and timing closure sign-off for low-power, chiplet-based MCU designs implemented on cost-optimized mature process nodes. This role is critical for ensuring design quality and convergence while meeting power, performance, and cost targets.

Job Description

• Drive RTL-to-gate synthesis for complex multi-die MCU designs using industry-standard tools
• Optimize for timing, power, and area while adhering to mature-node constraints
• Lead static timing analysis (STA) and timing closure activities across multiple corners and modes
• Ensure sign-off compliance for timing, power, and signal integrity
• Work closely with RTL, DFT, and physical design teams to resolve timing issues
• Own full chip constraints and design optimizations to achieve convergence
• Define and maintain synthesis and timing closure methodologies tailored for cost-sensitive MCU designs
• Evaluate EDA tools and flows for improved efficiency and turnaround time

Qualifications

• BTech/MTech in Electrical/Electronic Engineering, Computer Engineering or Computer Science with 15+years of experience in ASIC/SoC implementation
• Proven experience in mature-node technologies (e.g., 22nm, 12nm) and low-power design strategies and multi-clock domain designs
• Expertise in Synopsys/Cadence synthesis tools and STA tools
• Expertise in multi-mode, multi-corner timing analysis and constraint management
• Experience in timing closure of external interfaces like SPI/I2C/Ethernet/CAN
• Experience with hierarchical timing closure
• Experience with UPF/CPF-based power intent and low-power optimization techniques (clock gating, multi-voltage domains).
• Extensive experience with ECO flows for timing fixes and late-stage design changes
• Strong scripting skills (Tcl, Perl, Python) for automation of synthesis and STA flows
• Experience with timing sign-off for chiplet-based designs is a strong plus
• Strong communication skills (written and verbal), problem solving, teamwork, attention to detail, commitment to task, and quality focus
• Can – do attitude,openness to new environment, people and culture
• Ability to propose innovative and leading edge solutions
• Strong drive & ability to coordinate work across highly experienced global teams
