Principal Analog/Mixed-Signal Engineer
ExtropicJob Title
Principal Analog/Mixed-Signal Engineer
Role Summary
Design, simulate, validate, and bring to tape-out analog and mixed-signal blocks for modern CMOS processes. The role works within the hardware engineering team to develop high-performance analog IP—comparators, op-amps, references, regulators, oscillators/PLLs, and data converters—and to verify them through simulation and lab characterization.
Experience Level
Senior — requires 5+ years of relevant Analog/Mixed-Signal engineering experience.
Responsibilities
Primary hands-on responsibilities for this role include:
- Architect, design, and optimize analog building blocks (comparators, op-amps, references/biases, LDOs, filters, switch-cap topologies, ADC/DACs).
- Design and layout high-speed analog circuits including oscillators, frequency dividers, and PLLs with attention to performance and robustness.
- Perform detailed pre- and post-layout simulations (PEX, Monte‑Carlo, corner analysis) to meet specifications.
- Prepare and execute lab validation and characterization using signal generators, spectrum analyzers, oscilloscopes, and similar equipment.
- Support project tape-out verification (DRC, ERC, LVS) and resolve layout-related issues affecting reliability and performance.
- Implement techniques for noise reduction, linearity, stability, low-power operation, and reliability (including mitigation of electro-migration and layout effects).
- Collaborate with system and verification teams for pre-silicon validation and top-level mixed-signal simulations.
Requirements
Must-have technical skills and experience:
- 5+ years of relevant analog/mixed-signal design experience.
- Proven experience designing analog blocks and data converters (comparators, op-amps, references/bias, LDOs, filters, switch-cap circuits).
- Experience in design and layout of high-speed analog circuits (frequency dividers, oscillators, PLLs).
- In-depth knowledge of noise, linearity, stability, low-power and low-noise design techniques.
- Understanding of reliability and layout effects (electro-migration and mitigation strategies).
- Hands-on lab testing experience with signal generators, spectrum analyzers, and oscilloscopes.
- Comprehensive Cadence simulation skills including PEX, Monte‑Carlo, and corner analysis.
- Experience supporting tape-out verification (DRC, ERC, LVS) and pre-silicon validation workflows.
- Experience designing in modern CMOS processes.
Nice-to-have:
- Strong programming skills in Python and C.
- Experience with I/O design considerations (ESD protection and latch-up mitigation).
Education Requirements
Not specified.
