Key responsibilities include:

  • Managing the full SOC development lifecycle, including micro-architecture, RTL design, verification, DFT, physical design, and tapeout management.
  • Collaborating with partners on software, firmware, and packaged part solutions, ensuring seamless integration and delivery.
  • Occasionally traveling and working on-site at customer premises to support project execution and strengthen customer relationships.

As a Principal Engineer, you will shape Synopsys' role as a trusted partner for advanced SOC design across multiple industries, including automotive, aerospace, and high-performance computing. You will advance the adoption of cutting-edge technologies and design methodologies in customer projects. You will mentor and develop engineering talent, fostering technical excellence and innovation within the team.

To succeed in this role, you will need:

  • BSEE, MSEE, or Ph.D. in Electrical and/or Computer Engineering.
  • Minimum 10 years of experience in SOC-level architecture and RTL development.
  • Proficiency in SOC system architecture, micro-architecture, RTL development, design verification, DFT, and tapeout management.
  • Expertise in high-performance computing architectures for mobile, data center, automotive, and edge computing SOCs.
  • In-depth knowledge of interconnect options (Arteris NOC, AMBA AXI, CXL, etc.) and SOC standard interfaces (PCIe, DDR, HBM, MIPI CSI/DSI, SPI, I2C).
  • Implementation experience with CPU architectures (RISCV, ARC, X86, ARM).
  • Hands-on experience with workflow tools (git, gitlab, github).
  • Ability to travel and work on-site as needed; eligibility for government security clearances is a plus.
