Senior Digital Systems & Emulation Architect

Renesaselectronics; Austin (TX); On-site; USD 150,000 - 190,000; Full time

Job summary

Renesas is seeking an experienced Senior Staff Digital Systems & Emulation Engineer to lead pre-silicon emulation and digital system validation for power management products. The role requires bridging system architecture, digital design, FPGA/emulation, control algorithms, and hardware validation with real-time prototypes.

You will own emulation architecture, develop reusable FPGA infrastructure, and mentor engineers across multiple teams, delivering robust prototypes ahead of silicon

Responsibilities

• Architect, develop, and maintain FPGA-based emulation platforms for advanced digital power controllers and mixed-signal power-management products.
• Map and integrate production or representative RTL into FPGA/emulation environments for pre-silicon feature development and validation.
• Develop reusable FPGA infrastructure, interfaces, test capabilities, and debug methodologies supporting multiple product generations.
• Develop and improve build, configuration, automation, and debug flows to make emulation environments accessible and repeatable across engineering teams.
• Support integration of FPGA/emulated controllers with real power stages, loads, instrumentation, and system-level hardware.
• Identify differences between ASIC and FPGA implementation and develop appropriate strategies to maintain meaningful system-level behavior and correlation.
• Understand and contribute to digital system architecture, microarchitecture, and RTL implementation where required.
• Analyze timing, latency, clock-domain, interface, datapath, and real-time execution requirements relevant to system behavior.
• Develop or modify synthesizable RTL blocks required for emulation, instrumentation, prototyping, and architectural exploration.
• Support integration and debug of digital interfaces, ADC/DAC data paths, PWM generation, telemetry, protection functions, state machines, and embedded control logic.
• Work with Digital Design and Verification teams to correlate behavior between behavioral models, RTL simulation, emulation, and silicon.
• Support implementation and evaluation of digital control and signal-processing functions used within power-management systems.
• Translate mathematical or system-level algorithms into practical fixed-point and real-time digital implementations.
• Evaluate effects of sampling rate, latency, quantization, numerical precision, filtering, and computational architecture on system performance.
• Implement and evaluate digital filters, signal conditioning, control-loop functions, and related DSP algorithms where required.
• Collaborate with system architects to rapidly prototype new algorithms before committing them to production RTL.
• Develop system-level emulation scenarios representing realistic customer use cases and operating conditions.
• Define measurable pass/fail criteria and validation methodologies for new architectural features.
• Correlate emulation results with simulation, behavioral models, bench measurements, and silicon measurements where available.
• Support pre-silicon validation of control-loop behavior, transient response, telemetry, protection mechanisms, sequencing, communication interfaces, and other system-level functions.
• Perform detailed debug across hardware, RTL, firmware, and system boundaries to identify root causes of complex issues.
• Define and improve methodologies for FPGA prototyping and emulation of mixed-signal and digitally controlled power systems.
• Develop reusable architectures, automation, scripts, and engineering workflows that reduce setup and debug time.
• Participate in architecture, design, and verification reviews and provide technical guidance on emulation feasibility and implementation trade-offs.
• Work independently on complex technical problems and drive issues to resolution across organizational boundaries.
• Mentor engineers in FPGA, digital design, emulation, and system-debug techniques.
• Document architecture, implementation, test methodology, limitations, and results to enable reuse across programs.

Education

Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related discipline
