[1] Embedded QA Test Engineer

[1] Embedded QA Test Engineer

• Design and execute test plans, test cases, and automated scripts for embedded firmware.

• Analog and digital sensor inputs (temperature, pressure, flow, level).
• DAC-based actuator systems such as valves and VFDs.
• PID loop functionality including overshoot and settling time.
• Simulate sensor signals using lab tools like potentiometers, waveform generators, and SPI simulators.
• Conduct system-level validation under varying load conditions (CPU, memory, I/O).
• Test and validate signal conditioning techniques (e.g., filtering, noise rejection).
• Execute robustness and edge-case tests: cable faults, boundary values, latency, and real-time constraints.
• Collaborate with development teams to reproduce bugs and conduct root cause analysis.
• Document detailed test reports and manage defect lifecycle using tools like Jira.
• Participate in the improvement of testing methodologies, frameworks, and CI/CD pipelines.

• Practical experience in testing embedded systems with ADC/DAC sensor interfaces.
• Proficient in SPI, I2C, UART protocols.
• Strong understanding of control systems and PID tuning concepts.
• Skilled in using lab instruments: oscilloscope, multimeter, logic analyzer, and signal generators.
• Knowledge of embedded C firmware and system-level behavior.
• Strong documentation and defect tracking abilities.
• Familiarity with SD card/EEPROM-based logging and validation.
• Experience with CI/CD tools such as Git and Jenkins.

• Exposure to industrial automation systems or fluid control products.
• Familiarity with communication protocols such as Modbus, CAN, or MQTT.
• Experience working on Linux-based embedded systems or RTOS environments.

• Bachelor’s or Master’s degree in Electronics, Instrumentation, Embedded Systems, or a related field.
