Senior Analog/Mixed Signal Engineer

Extropic; Waltham (MA); On-site; USD 120,000 - 190,000; Full time

Job summary

Extropic is hiring an Analog/Mixed-Signal Engineer to accelerate hardware development. The candidate should deeply understand CMOS device characteristics, noise, mismatch, linearity, and design trade-offs.

Required experience includes 3-5 years in analog/mixed-signal engineering, designing analog blocks, and performing high-speed analog circuit layout and verification, with familiarity in pre-silicon validation and tape-out support.

Qualifications

• Deep knowledge of analog/mixed-signal concepts (noise, linearity, stability).
• Experience designing analog blocks (op-amps, references, LDOs, filters).
• Strong background in high-speed analog circuits (dividers, oscillators, PLLs).
• Familiarity with device reliability, EM issues and mitigation strategies.
• Experience in lab-testing with signal generators, spectrum analyzers, oscilloscopes.
• Cadence simulations (PEX, Monte-Carlo, Corner analyses) and tape-out support.

Responsibilities

• Design and verify analog/mixed-signal blocks for CMOS processes.
• Conduct pre-silicon validation and top-level simulations.
• Support tape-out verification (DRC, ERC, LVS) and layout considerations.
• Collaborate with layout and test teams to resolve reliability and noise challenges.

Job description

Extropic is hiring an Analog/Mixed-Signal Engineer to help accelerate our hardware development. The ideal candidate would be someone with a deep understanding of Analog/Mixed signal design and needs to have a solid understanding of CMOS device characteristics, noise, mismatch, linearity and design trade-offs.

Required Experience

• 3-5 years relevant experience in Analog/Mixed Signal Engineering

• Experience designing analog blocks (Comparator, op-amp, reference/bias generation, LDO regulators, filters, switch-cap, and data converters)

• Experience in design and layout of high-speed analog circuits (Frequency dividers, oscillators, and PLLs)

• In-depth knowledge of analog mixed-signal concepts (Noise, linearity, stability, low-power, and low-noise techniques)

• Deep understanding of reliability issues and layout effects, such as electro-migration (EM), and strategies to mitigate them

• Experience in lab-testing of mixed-signal circuits and experience using signal generators, spectrum analyzers, and oscilloscopes

• Comprehensive simulation skills in Cadence (PEX, Monte-Carlo, and Corner analysis)

• Experience in supporting project tape-out verification (DRC, ERC, and LVS)

• Proficiency in pre-silicon validation and top-level mixed-signal design simulations

• Experience in designing with modern CMOS technology

Preferred Experience

• Strong programming skills (Python and C)

• Experience with I/O design (ESD and latch-up)
