Senior Staff Applications Engineer

Job Description

For the Renesas Performance Computing Power Emulation Engineering team, you will be part of a fast-paced power management team supporting pre-silicon new feature bring-up and tapeout validation for AI and cloud infrastructure products. You will engage cross-functionally with IC design, firmware engineering, power systems architects, and systems engineering teams to deliver the most innovative power solutions.

• Design multiphase power solutions for CPU/GPU/ASIC-class loads using digital multiphase controllers and Smart Power Stages.
• Design boards and power systems that interface with pre-silicon emulation of digital PWM controllers and power stages, enabling system-level validation ahead of silicon.
• Develop EVBs, including schematic capture, component selection, and thermal design.
• Oversee PCB layout for CPU/GPU-class boards to meet power delivery requirements, including current density, copper allocation, sensing, PDN, and thermal performance.
• Design and review high-speed digital routing, including differential clock and data pairs with controlled impedance and high-speed single-ended signals, managing crosstalk, reflections, and EMI.
• Validate power performance in the lab (load transient, efficiency, sequencing, protection, telemetry) and signal quality using oscilloscopes, VNAs, and TDRs.
• Support pre-silicon new feature bring-up and tapeout validation, working with IC design, firmware engineering, and power systems architects to debug and close issues.

• Bachelor's or Master's degree in Electrical Engineering or related field.
• 10+ years of relevant experience in power design for CPU/GPU/ASIC-class loads, including multiphase DC/DC converters and digital power management products, with strong emphasis on board-level design and validation.
• Experience with high-speed differential clock and data interfaces (Ser Des-class) and high-speed single-ended routing (such as DDR), including channel modeling, jitter/crosstalk analysis, eye diagrams, and compliance/margining.
• Strong lab skills with high-bandwidth instruments (scopes, VNAs, TDRs), power validation equipment, measurement-simulation correlation, fixture/probing design, and de-embedding.
• Demonstrated leadership in cross-functional design reviews, architectural influence, and clear communication of power and SI/PI concepts to diverse audiences.

• Hands-on experience with leading SI/PI/EM tools (e.g., Ansys HFSS 3D/Layout, SIwave, Clarity, CST, Keysight ADS Momentum/Sigrity, HSPICE, Hyper Lynx).
• Experience designing boards that interface with pre-silicon emulation platforms.
• Track record of bringing complex high-speed hardware from concept to production, including multiple design spins and volume manufacturing support.
• Experience with AVSBUS, SVID, SVI3, and PWM VID control bus architectures.
• Experience with high-speed differential clock and data interfaces such as PCIe, Ethernet, and USB, and high-speed single-ended interfaces such as DDR memory.

• Power Design:
  Digital multiphase VR design, Smart Power Stages, control loop theory, and PDN analysis.
• Design Tools:
  Proficiency in schematic capture and ECAD layout tools (such as Altium, Cadence Allegro, or Mentor Graphics).
• Analysis Software:
  Using simulation tools for electromagnetic and signal and power integrity analysis (such as Keysight Path Wave or Ansys HFSS).
• Lab Equipment:
  Hands-on operation of oscilloscopes, TDRs (Time-Domain Reflectometers), logic analyzers, and electronic loads.
