Full Job Description
Job Summary:

We are seeking an experienced Analog/Mixed-Signal IC Design Engineer to design and deliver high-performance integrated circuits from concept through silicon validation and production. This role spans architecture, circuit design, and lab bring-up, with significant ownership and direct impact on real products.

Responsibilities:
  • Design and develop analog and mixed-signal circuit blocks, including:
    • Data converters (ADC/DAC)
    • Amplifiers (LNA, TIA, op-amps)
    • Bandgap references, biasing circuits, and regulators
  • Define system architecture and drive trade-offs across noise, linearity, power, area, and bandwidth.
  • Perform transistor-level design, simulation, and optimization using industry-standard tools.
  • Develop behavioral models (Verilog-A / SystemVerilog RNM) for system-level verification and architectural exploration.
  • Work closely with layout to ensure performance through parasitic-aware design and careful floorplanning.
  • Run post-layout simulations and sign-off analyses (PVT, Monte Carlo, corner analysis).
  • Collaborate with digital and verification teams for robust mixed-signal integration.
  • Drive/manage silicon bring-up, debug, and lab characterization.
  • Drive clear design documentation and participate in design reviews.
  • Take ownership of deliverables and drive work to completion, including under tight timelines.
  • Contribute across disciplines as needed, including outside primary specialization.
  • Maintain organized workflows to manage simulations, design iterations, and analysis results

Experience/Qualifications:
  • MS or PhD in Electrical Engineering or related field.
  • Strong fundamentals in analog circuit design and device physics.
  • Proven experience designing and taping out analog or mixed-signal ICs.
  • Expertise in CMOS or SiGe design across one or more process nodes.
  • Proficiency with SPICE-based simulation tools (e.g., Spectre, HSPICE).
  • Deep understanding of noise, mismatch, stability, and nonlinearity.
  • Ability to design from first principles and solve complex circuit problems creatively.
  • Strong organizational skills to manage large design spaces (corners, Monte Carlo, trade-offs).
  • Demonstrated ownership mindset with a focus on delivering high-quality result.

Preferred Qualifications:
  • Experience with data converters, RF/analog front-ends, or high-speed interfaces.
  • Experience with both mature and advanced process nodes (FinFET or beyond) a plus.
  • Hands-on experience with silicon validation and lab debugging.
  • Experience contributing across full chip development cycles.
  • Experience with Cadence Virtuoso design environment.
  • Hands-on experience with layout, tapeout, and bench validation.
  • Familiarity with SystemVerilog RNM and/or Verilog-A modeling.

What We Value
  • First-principles thinking and strong engineering judgment.
  • Ability to navigate complex trade-offs across performance, power, and area.
  • Ownership from architecture through silicon validation.
  • Clear and effective communication in cross-functional teams.
  • Intellectual curiosity and a drive to continuously learn new tools, domains, and techniques.
  • Flexibility to contribute beyond core responsibilities in a fast-paced environment.
  • Strong organizational discipline when working across many design iterations.
  • Receptiveness to feedback and commitment to continuous improvement.
  • Reliability and accountability in meeting commitments.
  • Willingness to go the extra mile to meet critical milestones
