Analog/Mixed-Signal Engineer

Job Title

Analog/Mixed-Signal Engineer

Role Summary

The Analog/Mixed-Signal Engineer will design, simulate, layout-aware verify, and lab-test mixed-signal integrated circuits to support Extropic's hardware development and tape-out activities. The role works with cross-functional teams to deliver robust analog IP and top-level mixed-signal blocks for modern CMOS processes.

Experience Level

Mid-level (typical candidate: 3+ years experience in analog/mixed-signal IC design; exact years not specified).

Responsibilities

Key responsibilities include design, verification, and hands-on validation of analog and mixed-signal blocks across the project lifecycle.

• Architect, design, and simulate analog blocks (comparators, op-amps, references/bias, LDOs, filters, switched-capacitor circuits, data converters).
• Design and lay out high-speed analog circuits (oscillators, PLLs, frequency dividers).
• Perform detailed circuit simulation (PEX, Monte-Carlo, corner analysis) and support pre-silicon top-level mixed-signal simulations.
• Execute lab testing and characterization using signal generators, spectrum analyzers, and oscilloscopes; debug silicon behavior.
• Support tape-out verification (DRC, ERC, LVS) and address layout-dependent reliability issues (EM, latch-up mitigation).
• Collaborate with digital, test, and package teams to integrate analog IP and meet project schedules.
• Document design decisions, test plans, and validation results for manufacturing handoff.

Requirements

Must-have technical skills are listed first. Preferred skills are indicated.

• Proven experience designing a range of analog blocks and high-speed mixed-signal circuits.
• Strong knowledge of analog/mixed-signal concepts: noise, linearity, stability, low-power and low-noise techniques.
• Deep understanding of CMOS device behavior, layout effects, and reliability (e.g., electro-migration) with mitigation strategies.
• Hands-on lab experience testing mixed-signal circuits with standard RF and oscilloscope instrumentation.
• Extensive simulation experience in Cadence including PEX, Monte-Carlo, and corner analysis.
• Experience supporting tape-out verification flows (DRC, ERC, LVS) and pre-silicon validation.
• Experience designing for modern CMOS technologies.
• Preferred: Strong programming skills in Python and C.
• Preferred: Experience with I/O design concerns such as ESD and latch-up.

Education Requirements
