HybridEngineeringFull-time

Key Responsibilities

  • Architect and design high-speed analog and mixed-signal circuits, including:
    • Transmit drivers (linear and/or PAM-based)
    • Transimpedance amplifiers (TIAs) and receiver front-ends
    • Clocking and timing circuits (PLLs, DLLs, low-jitter references)
    • Biasing networks, bandgaps, and on-chip power regulation
  • Perform transistor-level design, simulation, and optimization across PVT corners.
  • Analyze and optimize bandwidth, noise, linearity, jitter, stability, and power.
  • Work closely with layout engineers on floorplanning, matching, isolation, and parasitic management.
  • Define and support silicon bring-up, characterization, and debug, including correlation to simulations.
  • Contribute to design methodology, IP reuse, and best practices across programs.

Required Qualifications

  • MS or PhD in Electrical Engineering or related field.
  • 7+ years of hands-on analog or mixed-signal IC design experience.
  • Strong fundamentals in:
    • Feedback and stability analysis
    • Noise and jitter modeling
    • High-speed analog circuit design
    • Power integrity and substrate isolation
  • Experience taking Driver, TIA, or related analog blocks through tape-out and lab validation.
  • Proficiency with industry-standard analog design and simulation tools.

Preferred Qualifications

  • BiCMOS (SiGe) and/or advanced CMOS nodes.
  • High-speed data-path or I/O-adjacent analog circuits.
  • Experience with process scaling and technology trade-offs.
  • Exposure to silicon debug, failure analysis, and yield learning.
