• Working on real-time signal analysis for communication systems
• Enhancing image and audio processing efficiency
• Using tools like MATLAB, Python, and LabVIEW for simulations

Signal Processing Engineers often contribute to AI-driven applications like voice recognition, autonomous vehicles, and health monitoring systems.

VLSI Engineer – Role and Responsibilities

A VLSI (Very Large Scale Integration) Engineer focuses on designing and developing semiconductor chips containing millions of transistors. They are responsible for creating the hardware backbone of modern computing devices.

Key Responsibilities:

• Designing and testing integrated circuits (ICs)
• Working on RTL coding, synthesis, and verification
• Collaborating with fabrication teams for chip production
• Using tools like Cadence, Synopsys, and Verilog/VHDL
• Ensuring power efficiency and speed optimisation in circuits

VLSI engineers play a pivotal role in developing processors, memory devices, and AI accelerators that define the tech industry’s pace.
