Staff Digital Mixed-Signal System Engineer - Austin, United States

Originally posted 5 October 2026 by the employer.

Develop, model, and verify digitally implemented mixed-signal data paths for digital power management products.

About the role

This role involves developing, modeling, and verifying digitally implemented mixed-signal data paths for digital power management products. The focus is on digital processing connecting analog measurements to control-loop decisions.

What you'll do

• Develop digital mixed-signal data paths for digital multiphase power controllers and power management products.
• Design and evaluate front-end digital signal-processing functions for sensed voltage and current information.
• Develop requirements for ADC interfaces and controllers, including sampling, timing, sequencing, and calibration.
• Create executable behavioral models and emulation-oriented representations for system and feature evaluation.
• Translate system and control-loop requirements into detailed RTL requirements, fixed-point formats, and verification criteria.
• Analyze fixed-point implementation tradeoffs involving numeric range, precision, quantization, and latency.

What you'll need

• 5+ years of relevant experience in digital design, mixed-signal systems, digital signal processing, power management, or semiconductor verification.
• Strong understanding of digital signal-processing concepts, fixed-point arithmetic, sampling, filtering, timing, latency, quantization, saturation, and numeric precision.
• Experience developing or verifying ADC-facing digital logic, sensor data paths, telemetry paths, digital controllers, or control-loop support functions.
• Experience translating system or feature requirements into detailed digital implementation requirements and measurable verification criteria.
• Experience with behavioral modeling, data analysis, simulation, or engineering automation using Python, MATLAB, C/C++, SystemVerilog, or similar tools.
• Ability to analyze complex behavior across digital and analog boundaries and investigate differences between expected and observed results.

Nice to have

• Master’s degree in Electrical Engineering, Computer Engineering, Signal Processing, Control Systems, or Power Electronics.
• Experience with digital power controllers, DC/DC converters, voltage regulators, power management ICs, or multiphase control.
• Experience with RTL development or verification using SystemVerilog or a similar hardware-description language.
• Experience with Python, MATLAB, C/C++, emulation, FPGA prototyping, behavioral modeling, or real-number modeling.
• Experience with ADC controllers, coherent sampling, digital filtering, decimation, telemetry, protection functions, or real-time control data paths.
• Experience developing fixed-point models and comparing their behavior with floating-point reference models or RTL implementations.
• Familiarity with control-loop behavior, including stability, bandwidth, transient response, and sampling effects.
• Experience debugging issues at the boundary among algorithms, RTL implementation, firmware configuration, mixed-signal behavior, and silicon measurements.
