Telecom Product Company is Looking for:
Senior Software Engineer W/DLMS Experience
The company is seeking a highly skilled Senior Software Engineer to build Large-scale DLMS meter and network simulators capable of generating billions of transactions from millions of simulated meters to certify the scalability of the head-end system (HES).
This role requires strong expertise in
DLMS/COSEM protocols, Java concurrency utilities, and IoT AMI technologies. The successful candidate will help in ensuring that the HES is production-ready for large-scale deployments, focusing on building scalable, responsive applications using advanced
Java multithreading techniques, MQTT, and CoAP for real-time IoT communications.
Job Requirements:
- 10+ years of Java development experience, with extensive expertise in Core Java concurrency utilities such as Executors, Futures, and Locks.
- Strong experience in DLMS/COSEM protocols, including hands-on experience with DLMS stacks such as Gurux.
- Expertise in developing multi-threaded, scalable applications to handle real-time IoT device communications.
- Proven experience with IoT protocols such as MQTT and CoAP, integrating them into large-scale DLMS systems.
- Hands-on experience with testing and deploying DLMS communication over RF (Radio Frequency) networks.
- Deep understanding of distributed systems and designing scalable solutions to support millions of devices concurrently.
- Expertise in cloud-based infrastructure (AWS, Azure, Google Cloud) to support large-scale simulations and testing environments.
- Knowledge of message queue systems like RabbitMQ, Kafka, and real-time data processing frameworks.
- Strong background in load testing frameworks (JMeter, Gatling) and performance profiling for large-scale applications.
- Knowledge of security standards in IoT and AMI environments, particularly DLMS encryption and secure communication protocols.
- Experience handling big data and large datasets generated by smart meters using SQL/NoSQL databases.
- System Design & Architecture: Ability to design end-to-end architectures for large-scale IoT networks with high throughput and low latency.
- Distributed Systems: Design and optimize fault-tolerant, distributed systems for real-time, large-scale meter communication.
- IoT Communication Protocols: Hands-on experience integrating MQTT, CoAP, and other lightweight IoT protocols into production systems is an asset.
Education/Certifications: Bachelor's degree in computer science or any other degree with relevant experience
Job Responsibilities:
- Lead the design, architecture, and development of a DLMS/COSEM simulator capable of processing high volumes of smart meter data.
- Architect and implement multi-threaded, scalable Java applications using Java concurrency utilities (e.g., Executors, Futures, Locks) 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 Java concurrency to simulate real-world behaviors of smart meters and communication networks.
- Implement and optimize communications using MQTT, CoAP, and other IoT messaging 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.
