Job Description
We are seeking a highly skilled Senior Software Test Engineer with extensive experience in DLMS/COSEM protocols, DLMS Compliance Test Tools, Compatibility Test tools and proficiency in ANSI C and Python to join our team. The ideal candidate will be responsible for Testing and maintaining large-scale DLMS meter and network simulators, ensuring the scalability and performance of our Head End System (HES).
Key Responsibilities:
- Design, develop, and maintain DLMS/COSEM simulators capable of processing high volumes of smart meter data.
- Implement multi-threaded, scalable C applications using concurrency utilities to handle millions of devices and billions of transactions.
- Integrate DLMS protocol stacks (e.g., Gurux) with IoT AMI systems and the Head End System (HES) for comprehensive testing and simulation.
- Work on building responsive applications using C concurrency to simulate real-world behaviors of smart meters and communication networks.
- Implement and optimize communications using IoT messaging protocols such as MQTT, CoAP, and other protocols to simulate real-time smart meter data exchange over constrained networks.
- Design simulators to test DLMS communication stacks over Radio Frequency (RF) networks.
- Collaborate with cross-functional teams to ensure seamless integration of simulators with the Head End System, providing comprehensive testing for system scalability and performance under real-world conditions.
- Guide performance tuning for the HES to ensure low-latency, high-throughput transaction processing in large-scale deployments.
- Work closely with DevOps and testing teams to build automated testing tools for continuous integration and performance benchmarking.
