Responsibilities
- Build and maintain SystemVerilog-based simulation tests and environments executing ARM Cortex-M firmware with RTL and hardware models.
- Verify firmware 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 failures.
- Develop directed, constrained-random, negative, stress, boundary, and error-injection tests.
- Run regressions, triage failures, analyze waveforms and logs, and isolate issues to firmware, RTL, models, testbench, or tools.
- Track requirements, functional, code, and regression coverage and drive coverage-gap closure.
- Automate build and test execution, result checking, log parsing, failure classification, reporting, and continuous integration using Python, Perl, or similar scripting languages.
- Collaborate with firmware developers, RTL designers, architects, and validation engineers to improve observability, 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.
- 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.
- Strong ability to debug firmware-hardware interactions using simulation logs, waveforms, memory and register traces, and source-level analysis.
- Experience in firmware verification, embedded firmware testing, firmware development, or pre-silicon verification.
- Proficiency in Python, Perl, or similar languages for verification automation and regression infrastructure.
- Understanding of the embedded firmware development process across requirements, architecture, implementation, integration, test, debug, and release.
- Proven firmware testing experience including test planning, test-case design, negative and boundary testing, regression analysis, defect isolation, and coverage closure.
- Familiarity with embedded interfaces such as I2C, PMBus, SPI, UART, or similar protocols.
- Preferred experience with PMIC firmware, digital power management, voltage regulation, sequencing, telemetry, or protection features.
- Preferred hands-on experience with SystemVerilog-based pre-silicon simulation environments and waveform/debug tools such as SimVision or Verdi.
- Preferred knowledge of RTL design, firmware-controlled digital subsystems, automated regression farms, test dashboards, assertions, monitors, scoreboards, reference models, and diagnostic instrumentation.
- Experience with post-silicon bring-up or lab debugging, QEMU, emulation, FPGA-based prototyping, virtual platforms, UVM, or other structured verification methodologies is beneficial.
Benefits
- Competitive benefits package; further details are provided during the hiring process.
- Regular PERM employment; remote work is not available.
