Role Overview Description
Key Responsibilities:
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.

Engagement Type:

• Job Type: Contract
• Location: Remote
• Working time: 9:00 AM to 5:00 PM IST
