• Design and develop advanced test automation frameworks and scripts to enhance testing efficiency, accuracy, and coverage for embedded systems and communication protocols.
• Design, develop, and operate advanced Hardware-in-the-Loop (HIL), Firmware-in-the-Loop (FIL) and Software-in-the-Loop (SIL) test environments to simulate real-world grid conditions and validate embedded firmware performance.
•  Extensive hands-on experience in testing and validating embedded communication interfaces and tools, including Serial Port Monitor, Tera Term, and Wireshark, along with modules such as Wi-Fi, BLE, USB, and Ethernet, ensuring reliable connectivity, data integrity, and protocol compliance.
• Conduct R&D for power system domain applications.
• Perform deep-dive debugging of embedded firmware and hardware interactions during system failures, utilizing oscilloscopes and logic analysers for detailed signal and timing analysis.
• Develop and interpret wiring diagrams to ensure accurate system understanding and effective fault isolation.
• Develop detailed test plans, test cases, and test scripts based on product requirements and design documents.
• Define and implement overall testing strategies including functional, regression, performance, security, and automation testing.
• Knowledge in understanding Product Requirements, Marketing Requirements and deriving System Integration test cases.
• Contribute to risk assessment and mitigation strategies.
• Should be highly creative in coming up with out-of-box scenarios for testing and bugs
• Identify, analyse, and document defects using tracking tools
• Track defects through resolution and verify fixes
• Provide clear test reports, metrics, and dashboards to stakeholders.
• Collaborate closely with developers, product owners, and architects to ensure testability and quality in every stage of development.
• Participate in design and code reviews with a quality-first perspective.
• Advocate for quality engineering practices and continuous improvement.
• Provide technical guidance and mentorship to junior QA engineers.
• Lead test initiatives for large features or project modules.
• Perform end-to-end system analysis and design of complex systems (hardware, software, communications).
• Excellent verbal and written communication.
• Help establish and refine QA standards, processes, and documentation.
