About the job

Requirements
  • Typically 12–15+ years of experience in integrated circuit design, with a strong focus on debug, failure analysis, or sustaining engineering.
  • Strong analytical mindset and ability to drive structured, data-driven root-cause investigations independently and collaboratively.
  • Demonstrated experience diagnosing complex silicon or system-level failures across mixed-signal power management integrated circuit environments.
  • Solid understanding of analog and digital circuit behavior, waveform analysis, and how design implementation manifests on silicon.
  • Hands-on experience with industry-standard electronic design automation and debug tools, such as Synopsys, Cadence, oscilloscopes, logic analyzers, and simulation environments.
  • Strong attention to detail and accuracy, with ability to produce clear, concise technical reports and customer-facing documentation.
  • Excellent written and verbal cross-functional communication skills, including experience presenting technical findings to customers.
  • Structured problem-solving approach, openness to new perspectives, and ability to build consensus across engineering and customer teams.
  • Experience with failure analysis lab processes, failure analysis techniques such as scanning electron microscopy, focused ion beam, and emission microscopy, and interpretation of physical failure analysis results.
  • Knowledge of Verilog, Verilog-AMS, or scripting languages used to support debug automation or simulation.
  • Familiarity with 8D problem-solving methodology, structured debug reports, and customer quality processes.
  • Bachelor of Science or Master of Science in Electrical Engineering.
Responsibilities
  • Review return material authorization documentation and debug history to understand failure symptoms, and set up simulation and/or hardware debug environments to reproduce reported issues.
  • Collect and analyze waveforms, run analog simulations, and review register-transfer-level descriptions and netlists to identify potential failure mechanisms and silicon behavior anomalies.
  • Work closely with customer applications teams to align on debugging focus, share regular status and progress updates, and drive structured investigation plans.
  • Initiate further analysis where required, such as failure analysis lab work, interpret results, and plan next actions to converge on root cause.
  • Create customer-facing presentations, 8D reports, and other relevant technical documents throughout the investigation lifecycle.
  • Propose silicon fixes or system-level workarounds, outline validation strategies, and review feasibility with customer applications teams and relevant internal departments.
  • Deliver comprehensive debug reports covering root-cause analysis, fix proposals, and supporting data in a clear and structured format for internal and external stakeholders.
  • Conduct technical handoff meetings to ensure smooth knowledge transfer and formal case closure with all relevant teams.
  • Engage with design, applications, test, and quality engineering teams to share learnings, drive design improvements, and contribute to sustaining quality initiatives.
  • Disseminate lessons learned across Renesas design teams.
  • Proactively implement solutions with minimal input from the manager.
  • Share technical expertise in analog design across the power management integrated circuit organization through forums such as lunch-and-learns and skills training.
  • Demonstrate Renesas values in all aspects of work.
  • Continuously improve technical and non-technical skills, as measured through manager review.

What critics are saying

  • Renesas sued Navitas on July 22, 2026, and Navitas countersued August 10, 2026.
  • Takasaki factory production ends within two to three years, signaling legacy manufacturing strain.
  • GaN and autonomous-driving bets face execution risk if AI-data-center and SDV wins slip.

What makes Renesas Electronics unique

  • Altium plus Pictorus unify Renesas 365, spanning design, simulation, and deployment.
  • R-Car Gen 5 anchors open Autoware partnerships across Level 2+ to Level 4 autonomy.
  • Renesas leads automotive MCU, analog, and power silicon for high-reliability embedded systems.

Renesas launches 100V GaN FETs for AI data centres with 63% lower soft-switching losses

Renesas Electronics has launched its first 100V gallium nitride (GaN) power transistors for low-voltage applications. The new family of GaN FETs targets AI data centres, humanoid robotics, factory automation, industrial motor drives, power tools, and solar microinverters. The devices deliver up to 35% lower hard-switching figure-of-merit and up to 63% lower soft-switching figure-of-merit compared to comparable GaN products. They maintain silicon-compatible footprints for easy integration into existing designs. The transistors support the transition to 800V direct current power distribution and 48V bus architectures in AI servers and industrial infrastructure. They enable megahertz-class switching speeds whilst reducing passive component size, switching losses, and cooling requirements. The GaN FETs are available now in FCLGA and FCLGA-DSC packages, with corresponding evaluation boards.

Renesas launches industry's first 650V GaN chip with dual-side cooling for megawatt-scale AI data centres

Renesas Electronics has launched the industry's first 650V gallium nitride device with dual-side cooling for AI data centres. The TP65H020G4PLSGBD delivers 20 milliohms on-resistance in an 8x8mm package, 57% smaller than existing alternatives. The device targets 800V DC/DC intermediate bus converters in megawatt-scale data centres, addressing space and thermal constraints as rack power approaches megawatt levels. Dual-side cooling reduces top-side thermal impedance by 10% whilst maintaining compatibility with standard silicon gate drivers. Renesas is currently sampling the device to major data centre manufacturers. A 6kW reference design achieved 2.6 kW/in³ power density with 0.21% higher efficiency than equivalent alternatives. Mass production is planned for mid-2027. The device will be showcased at OCP Global Summit in San Jose, California, from 12-15 October.
