• Provide architectural leadership and technical guidance for system-level design decisions across projects.
• Modeling & Analysis
• Develop and maintain low-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 insights to support analog design convergence and reduce silicon risk.
• Cross-Functional Collaboration
• 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.
• Documentation & Knowledge Capture
• 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.
• Required
• Minimum 7 years of experience in power management ICs, Chargers, or advanced power converter designs, including DC/DC converters or mixed-signal systems.
• Experience with power architecture 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.
• Preferred
• Experience contributing to PMIC, Charger, or MLC-based converter programs.
• Familiarity with Multi-Level Converter (MLC) architectures or other advanced/novel power converter topologies.
• Familiarity with multi-rail power systems and power sequencing.
• Experience supporting silicon bring-up, validation, and root-cause analysis.
• At Renesas, you can:
