About the Role

Renesas Electronics America is seeking a Senior Firmware Verification Engineer to own pre-silicon verification of embedded firmware for high-performance power management ICs. This role involves verifying ARM Cortex-M firmware in simulation environments and identifying defects before silicon availability.

Responsibilities

• Build, maintain, and enhance SystemVerilog-based simulation environments that execute ARM Cortex-M firmware with associated RTL and hardware models.
• Verify firmware behavior across various scenarios including reset, boot, initialization, configuration, sequencing, telemetry, protection, fault handling, recovery, and firmware–hardware interface.
• Analyze C and assembly firmware at source, instruction, register, memory, interrupt, and peripheral levels to diagnose functional and timing-related failures.
• Develop directed, constrained-random, negative, stress, boundary, and error-injection tests to validate expected behavior and robustness.
• Run regressions, triage failures, perform waveform, log, memory, and register analysis, and isolate issues to firmware, RTL, models, testbench, or tools.
• Define and track requirements coverage, functional coverage, code coverage, and regression quality; identify gaps and drive closure.
• Create automation using Python, Perl, or similar scripting languages for build and test execution, result checking, log parsing, failure classification, reporting, and continuous integration.
• Collaborate with firmware developers, RTL designers, architects, and validation engineers to review requirements, improve observability and controllability, reproduce defects, and verify fixes.
• Document verification plans, test procedures, coverage results, debug findings, known issues, and release-readiness assessments.

Requirements

• BS or MS in Electrical Engineering, Computer Engineering, Computer Science, or a related technical field.
• Minimum 5+ years of experience in firmware verification, embedded firmware testing, firmware development, or pre-silicon verification.
• Strong understanding of the embedded firmware development process and its various activities.
• Deep understanding of C and assembly-based firmware for ARM Cortex-M processors, including exception and interrupt handling, memory maps, startup code, registers, peripherals, and low-level debugging.
• Proven firmware testing experience, including test planning, test-case design, negative and boundary testing, regression analysis, defect isolation, and coverage closure.
• Strong ability to debug firmware–hardware interactions using simulation logs, waveforms, memory and register traces, and source-level analysis.
• Proficiency in Python, Perl, or similar languages for verification automation and regression infrastructure.
• Familiarity with embedded interfaces such as I2C, PMBus, SPI, UART, or similar protocols.
• Strong analytical, problem-solving, written communication, and cross-functional collaboration skills.
• Experience verifying PMIC firmware, digital power management, voltage regulation, sequencing, telemetry, or protection features.
• Hands-on experience developing, maintaining, or debugging SystemVerilog-based pre-silicon simulation environments.
• Experience with waveform and debug tools such as SimVision, Verdi, or similar tools.
• Working knowledge of RTL design and firmware-controlled digital subsystems.
• Experience with CI/CD pipelines, automated regression farms, test dashboards, and scalable failure-triage workflows.
• Experience improving firmware testability through assertions, monitors, scoreboards, reference models, hooks, or diagnostic instrumentation.
• Post-silicon bring-up or lab-debug experience is beneficial.
• Experience with QEMU, emulation, FPGA-based prototyping, virtual platforms, or other pre-silicon execution environments.
• Exposure to UVM or other structured verification methodologies and coverage-driven verification.
