Principal Systems Architect

Role Overview

The Principal Systems Architect will serve as a technical expert and customer advocate for our Standard Products portfolio. This role combines hands-on technical support, product definition, and cross-functional collaboration to ensure successful integration and adoption of our Standard Products portfolio across automotive, industrial, and consumer markets.

Experience Requirements

• 10+ years experience in: 
  • Automotive or industrial semiconductor systems.
  • Applications engineering, systems engineering, or architecture roles.
  • Mixed signal circuit design and analysis.
• Demonstrated track record of: 
  • Leading system‑level customer engagements.
  • Influencing product direction through architectural insight.
  • Supporting multiple product lines simultaneously.
• Prior experience in Field Applications, Systems Engineering, or Technical Leadership roles.
• BS-EE Required, MS-EE plus.

System Architecture & Technical Leadership

• Own system‑level architectural positioning product solutions across automotive and industrial platforms, including: 
  • Zonal controllers and centralized compute.
  • Power distribution (OBC, DC/DC, EPS, braking, ADAS).
  • Front‑end protection and sensing architectures.
• Translate customer system requirements into actionable guidance for product definition, New Product Initiatives, and portfolio gaps.
• Lead cross‑product architectural alignment across: 
  • Power regulation (LDOs, DC/DC, ideal diodes).
  • Current sensing and signal chain. (Amplifiers).
  • Logic and interface (I²C/I3C, SPI, GPIO).
  • Isolation devices. (Opto-Isolators, Digital Isolators).
  • Data storage (EEPROM).
• Act as the technical arbiter in architectural tradeoffs (accuracy vs. cost, integration vs. flexibility, roadmap timing vs. customer urgency).

Customer Engagement & Communication (Primary Focus)

• Serve as lead system architect in customer discussions: 
  • Technical workshops.
  • Architecture deep dives.
  • Roadmap alignment meetings.
  • Escalation support for complex design‑in issues.
• Drive system‑level credibility with Tier‑1s and OEMs (e.g., EPS, zonal, ADAS, powertrain, body electronics).
• Shape customer perception of onsemi as a system solution partner, not a component vendor.
• Support FAEs by providing system context, reference architecture, and competitive positioning guidance.

Product Strategy & Portfolio Influence

• Drive product roadmaps and New Product initiatives s by: 
  • Identifying system‑level gaps.
  • Providing architecture‑driven justification for investment decisions.
• Partner with Product Line, Marketing, and Applications teams to ensure roadmaps align with evolving customer architectures, not just pin‑to‑pin replacements.
• Contribute to architecture‑led differentiation, emphasizing innovation over replication.
