Senior Firmware Engineer

Renesas Electronics America is seeking a Senior Firmware Verification Engineer to join the Infrastructure Power team. This role owns pre-silicon verification of embedded firmware used to control high-performance power management ICs for data center, AI accelerator, networking, and computing platforms. The engineer will apply a solid understanding of the firmware development process to build effective test strategies, verify ARM Cortex-M firmware in simulation-based environments, and identify firmware, RTL, and interface defects before silicon availability. Key Responsibilities   Build, maintain, and enhance SystemVerilog-based simulation tests and environments that execute ARM Cortex-M firmware with the associated RTL and hardware models.   Verify firmware behavior across reset, boot, initialization, configuration, sequencing, telemetry, protection, fault handling, recovery, and firmware–hardware interface scenarios.   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 closely 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.
