The Staff Power Architect – System Design is responsible for architecture definition, modeling, and technical leadership for PMIC and advanced DC/DC converter products. This role provides architectural ownership and technical leadership from concept through silicon validation. The role works closely with analog design, digital, verification, validation, test, and product engineering teams to ensure alignment of architecture intent, implementation, and verification across multiple programs.

Key Responsibilities

System Architecture & Technical Leadership

- 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.

Modeling & Analysis

- 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.

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 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.

Nice to Have

- Experience contributing to advanced power converter programs.

- Familiarity with emerging architectures such as Multi-Level Converter (MLC) topologies.

- Familiarity with multi-rail power systems and power sequencing.

- Experience supporting silicon bring-up, validation, and root-cause analysis.

What Success Looks Like

- Architectures are clearly defined and consistently implemented across projects.
