Full Job Description
Position Overview

We are seeking an experienced Analog / Mixed-Signal IC Design Engineer to design and deliver high-performance Driver and TIA circuits in BiCMOS and advanced semiconductor nodes. This role involves end-to-end ownership of analog building blocks, from architectural definition through silicon validation, in a fast-moving and technically rigorous environment. You will collaborate closely with digital, layout, and validation teams to deliver scalable, manufacturable analog IP.

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.


Why Join
  • Deep technical ownership with visible impact.
  • Opportunity to work in advanced semiconductor technologies.
  • Small, focused teams with high engineering standards.


Benefits:
  • Competitive salary and significant equity compensation in a rapidly growing, well-funded startup.
  • Comprehensive health, dental, and vision insurance.
  • Flexible time off policy.
  • Direct impact on groundbreaking technology shaping the future of AI and data centers.
  • Opportunity to work with a highly experienced and collaborative team.
  • Dynamic and innovative work environment
  • Opportunity for rapid career growth
