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

- 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)
