The ideal candidate will have a strong understanding of embedded systems, software testing methodologies, and experience with relevant tools and technologies.

Responsibilities:

• Develop and execute comprehensive test plans and test cases for embedded firmware and software, particularly for systems utilizing STM32 and SAM microcontrollers.
  
• Design, develop, and maintain automated test scripts and frameworks, potentially using scripting languages like Python.
  
• Perform functional, regression, performance, and stress testing on embedded systems.
  
• Identify, document, and track defects throughout the development lifecycle.
  
• Collaborate closely with firmware and application development engineers to understand system requirements, troubleshoot issues, and ensure test coverage.
  
• Participate in hardware bring-up, system integration, and validation activities.
  
• Utilize debugging tools such as JTAG, oscilloscopes, logic analyzers, DMMs, power supplies, and function generators to diagnose and verify issues.
  
• Develop and maintain test documentation, including test plans, test cases, and test reports.
  
• Work with real-time operating systems (RTOS) like FreeRTOS or similar, understanding their implications for testing.
  
• Test low-level drivers for peripherals such as UART, SPI, I2C, and other communication interfaces (e.g., CAN, Ethernet, USB).
  
• Validate GUI applications developed for testing system functionality, potentially using Qt/C .
  
• Contribute to the improvement of QA processes and methodologies.
  
• Ensure that GUI designs for ATE and checkout systems effectively facilitate testing and validation.
  
• Test GUI features for monitoring, configuring, and controlling ATE hardware and the Device Under Test (DUT).
  
• Verify GUI functionalities for data acquisition, management, storage, and report generation.
  
• Support the integration of ATE equipment and troubleshoot hardware/software issues related to testing.
  

Required Skills:

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
  
• Proven experience in software quality assurance or testing, preferably in embedded systems.
  
• Strong understanding of software testing principles, methodologies, and best practices.
  
• Proficiency in C and/or C .
  
• Experience with microcontrollers, preferably STM32, SAM, and ARM architectures.
  
• Experience with testing embedded systems and debugging tools (e.g., JTAG, oscilloscopes, logic analyzers).
  
• Familiarity with real-time operating systems (RTOS).
  
• Knowledge of microcontroller peripheral interfacing (SPI, I2C, UART, etc.).
  
• Experience with version control systems (e.g., Git).
  
• Strong problem-solving, analytical, and debugging skills.
  
• Excellent communication and teamwork skills.
  
• Experience in the design and/or utilization of Automated Test Equipment (ATE) or checkout systems.
  
• Familiarity with GUI design principles and testing.
  

Good-to-Have Skills:

• Experience with scripting languages such as Python for test automation.
  
• Experience with Qt/C for understanding or developing test support GUIs.
  
• Knowledge of communication protocols such as CAN, Ethernet, USB, SpaceWire, or MIL-STD-1553.
  
• Experience with test management tools.
  
• Familiarity with agile development methodologies.
  
• Experience with unit testing frameworks.
  
• Understanding of test and measurement instruments and their integration with software.
  
• Exposure to NI testing standards, Configurable DAQ systems / Checkout Systems such as PCI Express Cards/Racks, LXI systems, and USB Multi-I/O checkout systems.
  
• Experience working with NI-VISA supported LXI-based DMMs, Oscilloscopes, Power Supplies, Function Generators.
  
• Knowledge of secure boot and firmware update mechanisms testing.
