About the Job

Requirements

  • Ph.D. in Electrical Engineering or a related field with at least 6 years of analog/mixed-signal integrated-circuit design experience, or an MS in Electrical Engineering or a related field with at least 8 years of analog/mixed-signal integrated-circuit design experience.
  • Experience designing wideband amplifiers, comparators, bias networks, and ESD-tolerant input/outputs.
  • Experience with laser/modulator drivers and transimpedance amplifiers for optical interconnect applications.
  • Experience designing high-speed ADCs and DACs, including pipeline, SAR, flash, and current-steering converters, as well as low-speed converters for control and calibration planes.
  • Experience with clocking systems including DLLs, resonant/CMOS clock distribution, fractional-N synthesis, jitter budgeting, and LC or ring oscillators.
  • Hands-on design experience in advanced FinFET nodes (TSMC or Samsung 5–16 nm) and/or silicon-on-insulator processes.

Responsibilities

  • Design and verify high-speed analog and mixed-signal circuits, including ADCs, DACs, PLLs, clock distribution, laser/modulator drivers, and transimpedance amplifiers.
  • Architect and implement wireline SerDes front-ends, optical interconnect ICs, and multi-GHz analog signal chains from concept through tape-out.
  • Develop transistor-level schematics and layouts in advanced FinFET (7–16 nm) or SOI technologies, collaborating with layout engineers to meet PPA targets.
  • Drive pre-silicon simulation and post-silicon bring-up, analyze measured silicon data, and iterate on designs to close specification gaps.
  • Partner with digital, CAD, and systems teams to define mixed-signal partitioning, interface specifications, and shared design methodologies.
  • Produce detailed design documentation and present technical progress to cross-functional stakeholders and leadership.
  • Mentor junior designers and contribute to best-practice development across the organization.

Desired Qualifications

  • RFIC design experience with LNAs, mixers, PA drivers, broadband amplifiers, or RF front-end modules.
  • Familiarity with high-speed wireline PHY architectures, including 56G/112G PAM-4 SerDes and NRZ.
  • Background in optical module ICs, including TOSA/ROSA driver ASICs and coherent DSP interfaces.
  • Proficiency with Cadence Virtuoso, Spectre, APS, Ultrasim, and industry-standard layout tools.
  • Proficiency in designing RF passives such as transmission lines, inductors, and T-coils using electromagnetic tools such as EMX and Peakview.
  • Laboratory characterization skills using oscilloscopes, VNAs, spectrum analyzers, and BERT setups.
  • Publications or patents in analog/mixed-signal IC design.
