Senior Functional Test Engineer — Debug & Validation

Littelfuse; Piedras Negras; Presencial; MXN 600.000 - 900.000; Jornada completa

Descripción de la vacante

Littelfuse is seeking a Functional Test Engineer to validate complex hardware and software systems, develop validation environments, and drive root-cause analysis across hardware, firmware and software teams.

You will build automation tools in Python and LabVIEW, triage failures, document processes in Jira and Git, and work with cross‑functional colleagues to ensure robust, market‑ready products. This role requires 10+ years of experience and a strong background in ASIC/SoC bring‑up.

Formación

• 10+ years of experience in system validation, functional testing, ASIC/SoC debug, or related engineering roles.
• Strong understanding of computer architecture, microprocessors, memory subsystems (DDR, PCIe), and communication protocols (I2C, SPI, UART, USB).
• Proficiency in scripting and automation languages such as Python, LabVIEW, or Ladder Logic.
• Working knowledge of C/C++ for firmware or driver‑level debugging.
• Experience with version control and bug tracking tools (Git, Jira, Bugzilla, or equivalent).
• Exceptional analytical and problem‑solving skills with a structured, investigative mindset.
• Strong communication skills, able to explain complex technical issues to both technical and non‑technical audiences.

Responsabilidades

• Executes functional validation plans and test suites at system and subsystem levels under a variety of operating conditions.
• Acts as the first line of defense for system failures by isolating, reproducing, and debugging complex functional, performance, and power‑related issues.
• Performs deep‑dive root cause analysis to determine whether failures originate from hardware, software, firmware, or test environment issues.
• Develops and maintains automation scripts and tools (Python, LabView, etc.) to streamline test execution, data collection, and CI flows.
• Collaborates cross‑functionally with Hardware/ASIC Design, Firmware, Architecture, and Software teams to communicate findings, propose workarounds, and verify fixes.
• Documents debug methodologies, maintains detailed bug tracking records, and provides regular status updates to project stakeholders.
• Execute and triage complex system‑level validation scenarios, including performance, power, and functional coverage.
• Drive ownership of failure analysis from symptom to resolution, identifying cross‑domain interactions.
• Build and optimize validation tools, scripts, and infrastructure to improve efficiency and repeatability.
• Utilize lab equipment (oscilloscopes, logic analyzers, protocol analyzers, JTAG, PLC, DAC cards) and software debuggers (GDB, logging, tracing tools) as required.
• Partner closely with engineering teams to accelerate issue resolution and ensure design robustness.
• Maintain clear, structured documentation of bugs, test coverage, and debug processes using Jira, Git, or similar systems.
