Job description

We are seeking an experienced Lead / Principal PMIC System Architect to define and drive the architecture of next-generation automotive Power Management ICs (PMICs) for ADAS, Digital Cockpit, and Autonomous Driving platforms. The ideal candidate will translate system-level customer requirements into robust silicon architectures while ensuring compliance with ISO 26262 ASIL-B functional safety standards.

Key Responsibilities

• Define the architecture of complex automotive PMICs, including buck converters, LDOs, power stages, and power sequencing solutions.
• Translate customer and system power requirements into detailed product and micro-architecture specifications.
• Perform system-level modeling and simulations to optimize power efficiency, thermal behavior, reliability, and transient performance.
• Drive technical trade-off analysis and architecture decisions across performance, safety, cost, and power targets.

Functional Safety (ISO 26262)

• Own the development of Functional Safety Concepts (FSC) and Technical Safety Concepts (TSC).
• Architect and implement safety mechanisms such as voltage monitoring, watchdogs, thermal protection, diagnostics, and Built-In Self-Test (BIST) features to achieve ASIL-B compliance.
• Collaborate with functional safety teams to conduct FMEDA, DFMEA, and safety analysis activities.
• Support safety case development, validation, and certification activities.

Technical Leadership

• Partner with design, verification, validation, software, and product engineering teams throughout the product lifecycle.
• Guide architecture reviews, design decisions, and risk mitigation activities.
• Engage directly with customers to understand requirements and provide technical leadership on automotive power management solutions.

Experience required

• 10+yr industrial experience in the analog and mixed-signal design of PMICs, with a distinct focus on DC-DC converters (buck & boost), in the automotive domain.
• High voltage BCD expertise
• Solid knowledge of Analog circuit design in the PMIC domain: design of voltage/current references, amplifiers, comparators, filters, temperature and voltage sensors, oscillators, voltage clamps.
• Solid knowledge of switching power supply fundamentals, DC-DC converter topologies, PWM techniques, control loop stability, and transient response.
• Design stable control loops with compensation for load regulation, transient response, and output ripple.
• Understand closed-loop feedback systems' impact on stability in switching converters.
• Preferred knowledge of switching power supply fundamentals, DC-DC converter topologies, PWM techniques, control loop stability, high voltage buck converters with internal FET power switch and transient response.
• Select components considering voltage, current, speed, and thermal factors.
• Mitigate noise and EMI in analog circuits.
• Ensure compliance with industry standards and regulations, such as EMI/EMC and safety.

Preferred Qualifications

• Experience architecting safety-critical PMICs for automotive SoCs and ADAS platforms.
• Knowledge of ASIL-D decomposition methodologies.
• Expertise in PMIC communication interfaces such as I²C, SPI, and telemetry/control frameworks.
• Experience with functional safety validation, fault injection, and Hardware-in-the-Loop (HIL) testing.
• Prior experience leading PMIC product development from concept through production.
