Digital Mixed-Signal System Architect
HybridAustin, Texas, United States
Job Summary
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 information into control-loop, telemetry, protection, and diagnostic functions. Define ADC interface behavior, controller requirements, sampling relationships, data-valid timing, channel sequencing, calibration hooks, latency budgets, saturation behavior, quantization expectations, and error-handling requirements. Develop executable models and emulation-oriented representations that allow system behavior to be explored before RTL and silicon are complete. Translate system and control-loop requirements into RTL-facing specifications, fixed-point formats, datapath constraints, register behavior, firmware interfaces, and validation requirements. Collaborate with analog design experts on ADC and sensing assumptions while focusing ownership on the digital architecture, control data path, emulation behavior, and system-level integration. Work with firmware teams to define observability, debug access, telemetry behavior, configuration flows, and bring-up hooks needed for characterization and customer support. Partner with verification and validation teams to define reference scenarios, pass/fail criteria, correlation expectations, coverage targets, and structured evidence for architectural decisions. Analyze tradeoffs across loop performance, latency, noise sensitivity, resolution, dynamic range, power, area, configurability, implementation complexity, and customer-visible behavior. Document architecture clearly for cross-functional execution teams, including assumptions, interface contracts, model behavior, limits, corner cases, and validation expectations.
Required Qualifications
- Bachelor's degree in Electrical Engineering, Computer Engineering, or a related technical discipline
- 8+ years of experience in digital systems architecture, mixed-signal SoC architecture, digital signal processing, power management, control-oriented digital design, semiconductor verification, or related product development
- Strong understanding of digital signal-processing concepts, fixed-point arithmetic, sampling theory, filtering, timing, latency, quantization, saturation, and numeric precision tradeoffs
- Experience defining ADC-facing digital logic, sensor data paths, telemetry data paths, digital controllers, or control-loop support logic in a semiconductor product environment
- Ability to translate system-level requirements into RTL-facing architecture, firmware-visible behavior, emulation models, and validation-ready specifications
- Strong cross-functional communication skills, including the ability to align systems, digital design, firmware, analog, verification, validation, applications, and software/tool teams
Desired Qualifications
- Master's degree or PhD in Electrical Engineering, Computer Engineering, Signal Processing, Control Systems, Power Electronics, or a related discipline
- Experience with digital power controllers, DC/DC converters, voltage regulators, power management ICs, multiphase control, or high-current datacenter power applications
- Experience with RTL architecture, SystemVerilog, Python, MATLAB, C/C++, emulation, FPGA prototyping, behavioral modeling, real-number modeling, or hardware/software co-design
- Experience with ADC controller architecture, coherent sampling, digital filtering, decimation, telemetry, protection paths, loop compensation support, or real-time control data paths
- 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 comfortably at the boundary between algorithms, hardware architecture, firmware interface definition, and silicon validation evidence
