The Sr. Data Engineer will play a critical role in designing, developing, and maintaining the data infrastructure that powers real-time analytics and operational intelligence across IQ-STORAGE’s energy storage and renewables platforms. Working in close collaboration with the Principal Data Architect and cross-functional engineering teams, this role focuses on building reliable, scalable, and high-performance data pipelines to support digital twins, asset monitoring, performance analytics, and reporting across utility-scale Battery Energy Storage Systems (BESS), and EMS platforms.

Responsibilities:

• Develop, deploy, and maintain scalable data pipelines for ingesting high-frequency time-series data from EMS, SCADA, BMS, inverters, and other field devices.

• Build and manage data infrastructure to support operational dashboards, fleet-wide analytics, alarms, and forecasting models.

• Implement robust ETL/ELT processes that transform raw telemetry and event data into curated, analytics-ready datasets.

• Ensure pipeline reliability, performance, and data integrity across real-time and historical data systems.

• Support integration of asset performance data with visualization tools like Grafana, Power BI, and Tableau for operations, reporting, and customer portals.

• Collaborate closely with the Principal Data Architect to translate data strategy and models into production-grade infrastructure and services.

• Work with cloud and hybrid environments to deliver resilient, cost-effective data solutions using platforms like AWS, Azure, or on-premise data lakes.

• Enable data ingestion from distributed energy assets via MQTT, OPC UA, REST APIs, and edge gateways.

• Establish automated validation, testing, and monitoring to ensure data quality and early detection of anomalies or sensor failures.

• Contribute to toolchain improvements and DevOps practices for versioning, deployment, and CI/CD.

• Collaborate across product, analytics, and engineering teams to deliver data services that support energy forecasting, asset optimization, and compliance reporting.

Required Qualifications and Skills:

• Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, or a related technical field.

• 5+ years of experience in data engineering, with proven work in energy, renewables, industrial IoT, or real-time systems.

• Proficiency in Python and SQL; experience with Java or Scala is an asset.

• Experience handling time-series and event-based data at scale using platforms like InfluxDB, and TimescaleDB.

• Strong familiarity with SCADA, EMS, or BMS data structures, including Modbus, MQTT, and OPC protocols.

• Proven experience in data orchestration tools (e.g., Apache Airflow, Prefect) and real-time streaming platforms (e.g., Kafka, Spark Streaming).

• Experience working with cloud-native data solutions (e.g., AWS S3, Redshift, Kinesis, Azure Data Lake, GCP BigQuery).

• Strong knowledge of data security, access control, and compliance standards in energy environments (e.g., NERC CIP, ISO 27001).

• Hands-on experience integrating with visualization and reporting platforms like Grafana, Power BI, or Tableau.

• Familiarity with infrastructure-as-code (e.g., Terraform), Docker, and containerized workflows.

• Comfortable working in agile, cross-functional teams and collaborating with product, controls, and analytics groups.
