About the role
The Principal Analog Mixed-Signal Engineer will ensure first-pass success on Analog CMOS circuit solutions, leveraging SiTime's MEMS technology.
What you'll do
- Develop precision timing circuit architectures, design innovative circuits with aggressive technical performance specifications, performing transistor-level design and simulations.
- Plan and execute circuit designs that address demanding frequency stability, phase noise, power consumption, and silicon die area specifications.
- Perform technology, architecture, circuit design, and parametric design trade-offs to accomplish spec-compliant designs.
- Supervise and guide Senior Analog Circuit Designers, and supervise Analog Circuit Physical Design Layout.
- Perform post-layout parasitic-extraction and back-annotated simulations to validate design across Process, Voltage, Temperature.
- Initiate Design-of Experiments for Root Cause Analysis, investigate anomalous observations in silicon across PVT conditions, and propose solutions.
What you'll need
- MS Degree in Electrical Engineering.
- Minimum 10 years of high-performance analog circuit design experience.
- Proven track record in Circuit Architecture development and technical feasibility studies, Design partitioning for phase noise / power budgeting, Writing detailed block-level specifications, and Detailed design, test bench development, and simulation of basic analog building blocks.
- Expert-level experiential knowledge of architecting and implementing ultra low-jitter, power-efficient Frac-N PLLs.
- Experiential knowledge of ultra-low phase-noise design, power supply noise considerations, device matching, parasitic extraction, and signal integrity.
- Chip-level design and verification of complex mixed-signal chips.
Nice to have
- PhD in Electrical Engineering.
- 3 years of prior lead/supervisory/managerial experience.
