Role: Staff Analogue IC Design Engineer – High-Speed Custom Logic
Department: IC Design / Hardware Engineering
Location: Bangalore (Hybrid / Onsite / Remote)
Employment Type: Permanent, Full-Time
Level: IC3.5 / IC4

The Staff Analogue IC Design Engineer will join a senior analogue design team
responsible for pushing the performance limits of advanced CMOS technologies (≤45
nm). The role focuses on hand-crafted, high-speed custom logic, particularly domino
and energetic logic architectures, to implement arithmetic building blocks and ultradeep pipelines operating near process limits.

The engineer will be responsible for architecture, design, verification, and silicon
correlation of high-performance logic circuits and will collaborate closely with layout
engineers to achieve optimal performance under real physical constraints.

Key Responsibilities
Architecture & Circuit Design
• Architect and design high-speed custom logic blocks including:
o Serial and parallel adders
o Modular arithmetic units
o Shift registers




• Implement circuits using domino and dynamic logic techniques optimised for
maximum speed.
• Perform device sizing and topology selection for critical logic paths.

Dynamic Logic Optimisation
• Design and optimise domino logic paths including:
o Keeper strategies
o Clock skew management
o Charge sharing mitigation
o Noise robustness
o Setup and hold margin analysis

Performance & Timing Closure
• Achieve timing closure for ultra-deep pipelined logic structures.
• Conduct PVT corner analysis and statistical variation studies.
• Evaluate effects of process scaling, supply integrity, and interconnect
parasitics.

Verification & Simulation
• Develop and maintain golden simulation testbenches.
• Perform mixed-signal and transient simulations using Spectre/APS.
• Conduct corner, Monte Carlo, and transient noise simulations.

Layout Collaboration
• Work closely with layout engineers to ensure parasitic-aware optimisation.
• Account for layout-dependent effects incl
