Our Hardware Engineers at Synopsys are responsible for designing and developing cutting-edge semiconductor solutions. They work on intricate tasks such as chip architecture, circuit design, and verification to ensure the efficiency and reliability of semiconductor products. These engineers play a crucial role in advancing technology and enabling innovations in various industries.

You are a passionate and technically adept engineer who thrives in a fast-paced, collaborative environment. With a strong background in digital design and verification, you possess an in-depth understanding of RTL-based IP core development, particularly for high-speed memory interfaces such as HBM. You are driven by curiosity and innovation, eager to tackle complex challenges in the semiconductor industry.

Responsibilities:

  • Designing and implementing RTL-based HBM controller IP cores for cutting-edge SoC applications.
  • Interpreting and translating standard and product functional specifications into detailed micro-architectures.
  • Making architectural and methodological judgments for both design and verification activities.
  • Developing comprehensive verification strategies, including testbench architectures using SystemVerilog and UVM.
  • Creating and maintaining verification plans, item lists, coverage metrics, and checker definitions to ensure thorough validation.
  • Coordinating and leading design review meetings to ensure alignment and technical excellence across global teams.
  • Providing technical leadership and mentoring to junior engineers, setting quality standards and driving innovation.
  • Documenting progress, generating reports with “visible” verification metrics, and ensuring project milestones are met.

The Impact You Will Have:

  • Delivering high-quality, robust HBM controller IP that accelerates time-to-market for Synopsys customers.
  • Enabling key innovations for AI, automotive, server, and data center applications through advanced memory interface solutions.
  • Reducing integration risk and enhancing system performance for a broad portfolio of end-customer products.
  • Driving technical excellence and best practices across global, cross-functional engineering teams.
  • Supporting Synopsys’ reputation as a leader in silicon IP by ensuring products meet and exceed industry standards.
  • Contributing to continuous improvement by identifying and implementing process, methodology, and tool enhancements.
  • Mentoring and developing the next generation of engineering talent within Synopsys.

Requirements:

  • Extensive hands-on experience with RTL design and micro-architecture development from functional specifications.
  • Proficiency in verification methodologies (UVM/VMM/OVM), SystemVerilog, and object-oriented verification techniques.
  • Deep understanding of SoC/ASIC design flows, verification planning, and coverage-driven verification.
  • Experience with simulation tools, Unix operating environments, and scripting languages (Perl, Python, TCL).
  • Solid knowledge of protocols such as DDR, PCIE, AMBA (AXI/CHI), SD/eMMC, Ethernet, USB, and MIPI.
  • Strong English communication skills and the ability to document and present technical concepts effectively.
  • BSEE with 9~10+ years or MSEE with 7~12+ years of relevant experience.

Benefits:

  • Comprehensive medical and healthcare plans that work for you and your family.
  • In addition to company holidays, we have ETO and FTO Programs.
  • Maternity and paternity leave, parenting resources, adoption and surrogacy assistance, and more.
  • Purchase Synopsys common stock at a 15% discount, with a 24-month look-back.
  • Save for your future with our retirement plans that vary by region and country.
  • Competitive salaries.
