Digital Mixed-Signal System Architect - Austin, United States
Originally posted 21 July 2026 by the employer.
This role focuses on digital architecture for power management products for AI, datacenter, and high-performance computing applications.
About the role
This role defines, models, and validates digitally implemented mixed-signal data paths for digital power management products. The focus is on digital architecture connecting analog measurements to control-loop decisions, including ADC interfaces, ADC controllers, and digital signal processing.
What you'll do
- Define digital mixed-signal system architecture for digital multiphase power controllers and related power management products.
- Architect front-end digital signal-processing paths to filter, condition, scale, decimate, observe, and route sensed voltage and current.
- Define ADC interface behavior, ADC controller requirements, sampling relationships, timing, calibration hooks, and error-handling.
- Develop executable models and emulation-oriented representations to explore system behavior before RTL and silicon.
- Translate system and control-loop requirements into RTL-facing specifications, fixed-point formats, datapath constraints, and firmware interfaces.
- Document architecture for cross-functional execution teams, including assumptions, interface contracts, model behavior, and validation expectations.
What you'll need
- 8+ years of experience in digital systems architecture, mixed-signal SoC architecture, digital signal processing, power management, or control-oriented digital design.
- Strong understanding of digital signal-processing concepts, fixed-point arithmetic, sampling theory, filtering, timing, latency, quantization, and saturation.
- Experience defining ADC-facing digital logic, sensor data paths, telemetry data paths, digital controllers, or control-loop support logic.
- Ability to translate system-level requirements into RTL-facing architecture, firmware-visible behavior, emulation models, and validation-ready specifications.
- Bachelor's degree in Electrical Engineering, Computer Engineering, or a related technical discipline.
Nice to have
- Master's degree or PhD in Electrical Engineering, Computer Engineering, Signal Processing, Control Systems, or Power Electronics.
- Experience with digital power controllers, DC/DC converters, voltage regulators, or power management ICs.
- Experience with RTL architecture, SystemVerilog, Python, MATLAB, C/C++, emulation, or FPGA prototyping.
- Experience with ADC controller architecture, coherent sampling, digital filtering, decimation, or telemetry.
- Experience creating reusable models, reference tests, or structured engineering data that improve model-to-RTL, model-to-emulation, or model-to-silicon correlation.
- Ability to work at the boundary between algorithms, hardware architecture, firmware interface definition, and silicon validation evidence.
