• Support Hardware & Device Level Validations: Partner with engineering on activities including but not limited to Environmental Stress Testing. Connectivity resilience, Protocol conformance, Interference mitigation.
• Validate device and network performance: Test the functionality, reliability, and performance of connected devices, sensors, and network connectivity (e.g., Wi-Fi, Bluetooth, MQTT) under varying conditions.
• Ensure data integrity and security: Validate that data is securely and accurately collected, transmitted, and stored. Conduct security testing, including vulnerability scanning, and partner with the security team on penetration testing to identify and mitigate risks.
• Perform full-stack QA: Conduct API testing, UI presentation validations, message queue validation, cloud service verification to ensure seamless end-to-end integration and functionality.
• Simulate real-world conditions: Create and perform tests that simulate realistic network disruptions, device failures, and load conditions to ensure system resilience.
• Log and track defects: Document and report defects clearly to development teams and collaborate closely with them to verify bug fixes.
• Drive continuous improvement: Analyze test results, conduct root cause analysis, and contribute to continuous improvement efforts for the QA process.
• Database Validations: Write and execute SQL queries or other database querying language scripts (e.g., PL/SQL) to verify data consistency, accuracy, and adherence to business rules. Other Quality Skills o Function as the voice of quality within the team, proactively identifying and advocating for quality improvements. o Take initiative to understand quality standards and goals, both within the organization and the wider industry. o Demonstrate strong ownership of testing activities and deliverables, requiring minimal supervision. o Communicate clearly and concisely with developers, product managers, and other stakeholders, ensuring a shared understanding of quality expectations and issues. o Be able to convince colleagues and leadership of the benefits of quality assurance. o Maintain detailed and accurate documentation of test cases, test results, and defect reports. o Stay informed about industry trends and best practices in API testing, automation, and performance testing.
