Circuit Design Engineer

Job Description

Designation Senior Circuit Design Engineer / Circuit Design Engineer Education: Bachelors or Masters degree in Electronics, Electrical Engineering, or a related discipline. Skill sets : Hands-on experience in high-voltage design (up to 1kV) and safety standards related to creepage, clearance, and insulation coordination. Expertise in magnetics design including ferrite core selection, winding strategies, and leakage minimization. Strong command of PCB CAD tools: Altium Designer, Cadence Allegro, or Mentor Xpedition. Simulation expertise: SPICE, LTSpice, Keysight ADS, HyperLynx, CST Studio, and MATLAB/Simulink. Experience in IEC 60601-1/2, EN 61000 series, FCC Part 15, UL, and ISO 13485 environments. Key Responsibilities: Design and develop high-speed, multi-layer PCB circuits with high signal integrity and thermal performance. Develop isolated and non-isolated power supplies, including flyback, forward, and resonant converter topologies. Design and simulate low-noise analog circuits including active/passive filters, instrumentation amplifiers, and protection circuits. Integrate high-speed digital interfaces (DDR, HDMI, USB 3.1, MIPI, PCIe) with careful impedance and return path control. Perform worst-case circuit analysis (WCCA), Monte Carlo simulations, and tolerance analysis for reliability. Design magnetics (transformers, inductors) for custom power supply applications. Perform design reviews and ensure EMI/EMC standards (CISPR, MIL-STD, IEC 60601-1-2) are met through shielding, filtering, and layout optimization. Lead debugging of complex systems using advanced instrumentation (e.g., spectrum analyzers, VNA, Bode plotters, logic analyzers).
