Senior Analog/Mixed-Signal Engineer

Job Title

Senior Analog/Mixed-Signal Engineer

Role Summary

Join the hardware team to design and validate analog and mixed-signal integrated circuits for modern CMOS processes. Responsible for circuit design, simulation, layout collaboration, lab characterization, and tape-out support to accelerate product development.

Experience Level

Senior; the posting requests 3–5 years of relevant analog/mixed-signal engineering experience.

Responsibilities

Core responsibilities include design, verification, and validation of analog/mixed-signal circuits across pre-silicon and lab stages.

• Design analog blocks: comparators, op-amps, reference/bias generation, LDO regulators, filters, switched-capacitor circuits, and data converters.
• Design and characterize high-speed analog circuits: frequency dividers, oscillators, and PLLs.
• Perform Cadence-based simulation (PEX, Monte-Carlo, corner analysis) and interpret results for design decisions.
• Collaborate on layout for reliability and manufacturability; address electromigration and layout effects.
• Support tape-out checks and verification (DRC, ERC, LVS).
• Perform lab testing and characterization using signal generators, spectrum analyzers, and oscilloscopes.
• Lead pre-silicon validation and top-level mixed-signal integration.

Requirements

Must-have technical skills and experience; nice-to-have items listed separately.

• Must-have:
  • 3–5 years relevant experience in analog/mixed-signal engineering.
  • Proven experience designing analog blocks and high-speed analog circuits as listed above.
  • In-depth knowledge of noise, linearity, stability, low-power and low-noise techniques.
  • Experience with modern CMOS process design and layout reliability issues (e.g., electromigration mitigation).
  • Lab experience characterizing mixed-signal circuits and using oscilloscopes, signal generators, and spectrum analyzers.
  • Comprehensive Cadence simulation and verification skills (PEX, Monte-Carlo, corner analysis).
  • Experience supporting tape-out verification (DRC, ERC, LVS) and pre-silicon validation.
• Nice-to-have:
  • Programming skills in Python and C.
  • Experience with I/O design, ESD protection, and latch-up mitigation.

Education Requirements

Not specified.
