Functional Test Engineer (Experience in Debug) (Piedras Negras)

Functional Test Engineer (Experience in Debug) Ensuring that products meet architectural specifications and functional requirements, you will create validation environments, execute complex system-level test plans, and perform deep root-cause analysis on failures across hardware and software domains. You will collaborate with design, architecture, firmware, and software teams to isolate defects, validate fixes, and deliver high‑quality products to market. About Your Job
- 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.
- Executes and triages complex system-level validation scenarios, including performance, power, and functional coverage.
- Drives ownership of failure analysis from symptom to resolution, identifying cross-domain interactions.
- Builds and optimizes validation tools, scripts, and infrastructure to improve efficiency and repeatability.
- Utilizes lab equipment (oscilloscopes, logic analyzers, protocol analyzers, JTAG, PLC, DAC cards) and software debuggers (GDB, logging, tracing tools) as required.
- Partners closely with engineering teams to accelerate issue resolution and ensure design robustness.
- Maintains clear, structured documentation of bugs, test coverage, and debug processes using Jira, Git, or similar systems. About You
- 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.
- Resilient, detail-oriented, and persistent in highly iterative debug environments.
- Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field (or equivalent experience).
- Hands-on experience with ASIC or SoC bring‑up and post-silicon validation.
- Exposure to CI pipelines and automated validation frameworks.
- Experience working in highly cross-functional, integral engineering teams.
- Strong documentation skills and ability to create repeatable debug playbooks.
