We are seeking a highly skilled System Test Lead to oversee the testing and validation of large-scale IoT network platforms built on RF Mesh technology. The System Test Lead will be responsible for defining test strategies, frameworks, and procedures, leading a team of test engineers, and ensuring that the platform delivers high reliability, scalability, and performance in real-world deployments. This role is critical for maintaining the quality of IoT networks connecting thousands to millions of devices.

Key Responsibilities

• Define and own the system-level test strategy for RF Mesh-based IoT networks.
• Develop test plans, test cases, and validation procedures covering:
• Network scalability and reliability
• Device provisioning and firmware upgrades
• RF communication performance (link quality, packet loss, latency)
• Cloud integration and data management
• Ensure test coverage aligns with functional, performance, and non-functional requirements.
• Lead, mentor, and manage a team of system and test engineers.
• Collaborate with product, firmware, hardware, RF, and cloud teams to ensure comprehensive testing.
• Coordinate with field teams for real-world deployment testing and data collection.
• Test Execution & Automation
• Oversee manual and automated testing of the IoT platform.
• Implement and maintain test automation frameworks, scripts, and tools for large-scale network validation.
• Analyze test results, identify defects, and work with engineering teams for timely resolution.
• Support continuous integration and continuous deployment (CI/CD) testing pipelines.
• Performance & Reliability Testing
• Conduct stress tests, scalability tests, and long-duration reliability tests of RF Mesh networks.
• Validate network performance under different topologies, interference conditions, and real-world environments.
• Monitor KPIs such as packet delivery ratio, network latency, device uptime, and throughput.
• Documentation & Reporting
• Maintain detailed test reports, logs, and dashboards for stakeholders.
• Document test strategies, standard operating procedures (SOPs), and troubleshooting guides.
• Provide insights and recommendations to improve platform performance, reliability, and maintainability.

Required Skills

• Bachelor’s / Master’s degree in Electronics, Communication, Computer Science, or related engineering discipline.
• 5–10 years of experience in system testing or QA of embedded, IoT, or wireless networks, with at least 2 years in a lead role.
• Strong understanding of RF Mesh networks (Wi-SUN, IEEE 802.15.4g/e, 6LoWPAN, RPL).
• Hands-on experience in IoT network validation, scalability testing, and performance benchmarking.
• Knowledge of test automation frameworks, scripting (Python, Shell), and CI/CD pipelines.
• Experience with network monitoring tools, test instrumentation, and field testing.
