Senior mixed-signal electrical engineer

ASML•San Jose, CA

About The Position

Lead the design, analysis, and implementation of high-performance analog and mixed-signal circuits, including high-speed (>50 MSPS), high-precision (≥16-bit) DAC/ADC signal chains and low-noise, high-linearity, high dynamic range analog front-end (AFE) designs. Design and develop precision high-voltage circuits with high frequency (>5 MHz), low distortion, and ultra-low offset (<1 mV) operation in high-voltage environments up to ±225V, with robust stability and reliability. Architect and optimize complete end-to-end signal chains, including DAC/ADC interfaces, amplification, filtering, driver stages, feedback loops, and calibration. Perform modeling, simulation, and performance validation by developing both system-level (behavioral) and circuit-level (SPICE) models and analyzing key performance parameters such as noise, distortion, offset, drift, bandwidth, and stability. Drive laboratory debugging, validation, and system bring-up using advanced lab equipment (oscilloscope, spectrum analyzer, network analyzer, etc.), identifying and resolving issues related to signal integrity, EMI/EMC, thermal effects, and parasitic. Collaborate cross-functionally with digital, FPGA, system, power, and software teams to define hardware/firmware/software interfaces and support system-level integration and validation. Support the full product lifecycle, from concept to volume production, including design validation (DV), engineering validation (EVT), and manufacturing support, as well as root cause analysis (RCA) for field and production issues. Drive adoption of advanced technologies and architectures in high-performance systems and produce high-quality documentation, including design specifications, simulation reports, and test reports. Provide technical leadership and mentorship to junior engineers.
