Job description

onsemi is a global leader in intelligent power and sensing technologies, enabling automotive, industrial, and cloud customers to build safer, more sustainable, and more energy-efficient systems. The Treo™ platform is central to onsemi’s next-generation automotive and industrial SoC strategy, delivering scalable, safety-focused power, clock, and system management solutions.

Role Overview

We are seeking a Sr Principal Analog Design Engineer to provide technical leadership and hands-on design expertise for analog IP supporting the power, clock, and error management subsystems of the onsemi Treo™ platform.

This role is ideal for a highly experienced analog designer who has successfully delivered production-proven IP, understands automotive-grade quality and functional safety, and is comfortable operating in a digital-on-top SoC integration environment. The role combines deep technical ownership with mentoring, design review, and quality leadership responsibilities.

Responsibilities

Key Responsibilities

Analog IP Architecture & Design

• Architect, design, and deliver analog IP blocks for:
  • Power management (e.g., regulators, monitors, biasing)
  • Clock generation and distribution (e.g., PLLs, oscillators, clock monitors)
  • Error detection, monitoring, and safety-related analog circuitry
• Drive designs from concept and architecture through schematic, simulation, layout collaboration, and silicon validation.
• Ensure designs are robust, reusable, and scalable across Treo™ platform derivatives.

Production & Quality Ownership

• Own analog IP blocks that tape out and go to volume production, meeting performance, yield, and reliability targets.
• Act as a design quality reviewer, providing thorough technical reviews of:
  • Schematics
  • Simulation plans and results
  • Layout considerations
  • Documentation and sign-off readiness
• Champion best practices in analog design quality, robustness, and documentation.

SoC Integration & Cross-Disciplinary Collaboration

• Digital control and status visibility
• Power, clock, and reset integration
• Work closely with:
  • Digital design teams
  • Verification teams
  • Physical design and layout engineers
  • Systems and product engineering
• Support top-level integration, bring-up, and debug activities as needed.

Automotive & Functional Safety

• Design and deliver analog IP compliant with automotive-grade requirements, including:
  • Reliability
  • Diagnostic coverage
  • Fault tolerance and detection
• Apply functional safety concepts (e.g., ISO 26262) at the IP level, including:
  • Safety mechanisms
  • Redundancy and monitoring
  • Support for ASIL-driven requirements
• Collaborate with safety and systems teams to ensure traceability from requirements to implementation.

Technical Leadership & Mentorship

• Mentor and guide junior and mid-level analog engineers, fostering technical growth and design excellence.
• Provide hands‑on coaching in:
  • Analog fundamentals
  • Debug and failure analysis
  • Design trade‑offs and architecture decisions
• Serve as a technical role model within the Cork analog design organization.

Qualifications

Required Qualifications

• 12+ years of hands‑on analog design experience in IC or SoC development.
• Proven track record of designing analog blocks that have gone to production in shipped products.
• Strong experience designing power and/or clock IP blocks for SoC‑based products.
• Demonstrated ability to deliver analog IP into a digital‑on‑top integration flow.
• Experience developing automotive‑grade IP, with exposure to functional safety requirements.
• Deep understanding of analog design fundamentals, including:
  • Device physics
  • Noise, stability, and robustness
  • PVT and reliability considerations
• Strong communication skills and the ability to provide clear, constructive design reviews.

Preferred / Plus Qualifications

• Direct experience supporting ISO 26262 work products at the IP level.
• Experience with safety diagnostics, monitors, and fault‑injection concepts.
• Familiarity with mixed‑signal verification and post‑silicon debug.
