Role Summary

- We are looking for a Senior/Lead HES Integration Engineer with hands-on experience in Head-End Systems (HES), Advanced Metering Infrastructure (AMI), and DLMS/COSEM-based smart metering solutions.
- The role will involve configuring and operating the Head-End System, establishing and validating meter-to-HES communication using DLMS/COSEM, driving end-to-end AMI testing, and delivering robust HES-to-MDMS integrations.
- The ideal candidate should have strong technical expertise in smart metering, DLMS/COSEM protocols, HES/MDMS platforms, system integration, troubleshooting, and AMI data flows.
- Mode: Contract / Permanent

Key Responsibilities

- Configure and manage the HES, including meter onboarding and registration, communication profiles, scheduling and On-Demand Reads (ODR), job configuration, firmware OTA campaigns, and security/key management.
- Establish and validate meter-to-HES communication and ensure DLMS/COSEM compliance, including OBIS mapping, COSEM object and data-model validation, association setup, ciphering/security configuration, and push/event handling.
- Design, implement, and test northbound and southbound integrations between HES and MDMS, as well as CIS/billing systems, using IEC 61968-9/CIM interfaces, APIs, and data feeds.
- Execute end-to-end testing across the AMI chain (Meter → HES → MDMS), validating load profiles, instantaneous data, billing data, events/tamper data, and outage/last-gasp information.
- Troubleshoot non-communicating and never-communicating meters and perform root-cause analysis of communication, configuration, and data-quality issues.
- Support VEE (Validation, Estimation, and Editing) data handoff and integration with MDMS.
- Use large-scale meter and DLMS simulators to validate HES functionality, scalability, performance, and reliability before and during field deployment.
- Support field rollout activities, production issue resolution, system integration, and performance optimization.
- Collaborate with meter vendors, HES/MDMS teams, testing teams,



and business stakeholders to resolve integration and data-flow issues.

Required Technical Skills & Tools

- Hands-on experience with at least one HES/MDAS platform, such as:
- Cuculus ZONOS
- Siemens EnergyIP
- Itron IEE
- Elster EnergyICT
- Landis+Gyr Gridstream
- EDMI Storm
- Hands-on experience with at least one MDMS platform and a strong understanding of HES-to-MDMS data flows.
- Strong knowledge of DLMS/COSEM, including:
- OBIS codes and mapping
- COSEM objects and interface classes
- HDLC and TCP/IP communication profiles
- Association and authentication mechanisms
- Ciphering and security suites
- Push/event communication
- Knowledge of MODBUS is desirable.
- Experience with integration technologies and enterprise application stacks, including Java/J2EE, SOA, XML, and REST APIs.
- Working knowledge of Oracle/RDBMS, Linux, and messaging/streaming technologies such as Kafka.
- Understanding of VEE (Validation, Estimation, and Editing) concepts and MDMS data processing.
- Experience with DLMS tools and simulators such as Gurux, ASE62056, or equivalent meter/DLMS simulation tools.
- Experience with defect tracking and test management tools such as Jira and/or Azure DevOps.
- Strong troubleshooting, debugging, log analysis, and root-cause analysis skills.

Qualifications & Experience

- Bachelor's or Master's degree (B.E./B.Tech/M.Tech) in Electronics, Electrical Engineering, Computer Science, or a related engineering discipline.
- 3+ years of relevant experience in AMI, smart metering, HES, MDMS, or smart-grid system integration.




- Senior/Lead-level candidates should demonstrate robust ownership of HES integration, testing, troubleshooting, and deployment activities.
- Strong understanding of the end-to-end AMI data flow: Meter → HES → MDMS → CIS/Billing.
- Experience working with multiple meter vendors and heterogeneous AMI environments is highly desirable.
- Strong analytical, problem-solving, communication, and stakeholder-management skills.

Domain Knowledge – Australian Market

Candidates with experience in the Australian smart-metering ecosystem should have knowledge of:

- AEMO and the National Electricity Rules (NER) metering framework.
