The job description

Tech stack. Power management IC design, DC-DC converters, LDOs, Cadence Virtuoso, Spectre, control loop theory, power device design, EM and thermal analysis

About the role

You will design power management integrated circuits at a semiconductor company, creating the voltage regulators, converters, and power control systems that energize every electronic product. Power management designers work at the intersection of analog precision and power delivery: their buck, boost, and linear regulators must be efficient, stable under all load transients, quiet enough for sensitive loads, and robust across temperature extremes. Your designs determine battery life, thermal performance, and system reliability. You will also own load-transient and stability validation across the full operating envelope, closing the loop between Spectre simulation, control-loop analysis, and bench measurements on first silicon.

What you will achieve

Design switching regulators including buck, boost, and buck-boost converters meeting efficiency, transient response, output ripple, and EMI targets across the full operating range.
Design linear regulators including LDOs and references with excellent PSRR, load regulation, and quiescent current for noise-sensitive and always-on applications.
Analyze and stabilize control loops rigorously, ensuring phase margin and transient performance under worst-case load steps, input variations, and component tolerances.
Optimize power stage design including power FET sizing, gate drivers, and current sensing for the efficiency targets that define product competitiveness.
Validate power management ICs on the bench with comprehensive efficiency, transient, ripple, and protection testing, correlating results against simulation models.
Design protection features including over-current, over-voltage, thermal shutdown, and soft-start with correct, robust behavior under fault conditions.

What you will bring

Must-haves

5 to 8 years of experience in power management IC design with shipped high-volume products.
Deep understanding of switching converter topologies, control modes, and stability analysis.
Strong analog fundamentals applied to power: bandgaps, error amplifiers, comparators, oscillators, and current sensing.
Experience with power device design, gate drivers, and the layout practices critical for switching regulators.
Proficiency with Cadence tools and power-specific simulation including large-signal transient and efficiency analysis.
Bench validation expertise for power ICs including efficiency measurement, transient testing, and EMI characterization.
System perspective on how regulator performance affects the powered loads and overall product behavior.

Nice-to-haves

Experience with digital control loops or digitally assisted power management.
Knowledge of battery charging architectures and battery management systems.
Familiarity with advanced packaging for power density such as integrated magnetics.
Experience with automotive or industrial power IC qualification requirements.
