Qualifications

• Strong experience in PMICs, DC/DC converters, or mixed-signal power systems.
• Experience with architecture definition and architectural analysis for power management products.
• Familiarity with modeling tools such as Simplis and Simulink.
• Ability to work across disciplines and influence technical decisions through collaboration and technical credibility.
• Strong written and verbal communication skills for technical documentation and reviews.

Responsibilities

• Define and own architectures for PMIC and advanced power converter products across multiple programs.
• Drive architecture trade-offs and define operating modes, startup and shutdown sequencing, and system boundary conditions.
• Lead architecture reviews and remain deeply involved during the design phase to ensure the transition from architecture to design execution is carried out correctly.
• Provide architectural leadership and technical guidance for system-level design decisions across projects.
• Develop and maintain low-level and system-level models to support architecture decisions and risk reduction, using tools such as Simplis.
• Analyze stability, transient response, fault behavior, and corner cases to support architecture definition and validation.
• Provide model-based insight to support analog design convergence and reduce silicon risk.
• Collaborate with analog design, digital, verification, validation, test, and applications teams to ensure architecture intent is implemented and verified.
• Participate in design and architecture reviews and technical discussions across multiple programs.
• Provide technical guidance during silicon validation and system-level debug activities.
• Create and maintain architecture documentation, design guidelines, and best-practice references.
• Create detailed sub-block specifications that enable design and verification teams to execute implementation and verification activities efficiently.
• Capture lessons learned, root causes, and preventive actions to improve future designs.
• Contribute to internal training, workshops, and technical knowledge-sharing activities.
