# AWS Data Engineer

**ON.energy** · Argentina; Mexico City, Mexico City, Mexico

Apply: https://job-boards.greenhouse.io/onenergy/jobs/4402200009

## About ON.energy

ON Energy – Wir sind die Energiewende

## About the role

ON.energy is setting the standard for large load interconnection. ON’s patented AI UPS™ is a medium-voltage UPS that serves as a firewall, protecting the data center from the grid, and the grid from the data center. With multiple gigawatts currently under construction, we are enabling grid-safe data centers.

##### Role Summary

ON.energy is building the power infrastructure that makes the AI era possible. Our systems are deployed across 2.5 GW of hyper-scale campuses, validated by top U.S. national labs, and certified for grid-safe operation by major utilities. You’ll be the fourth engineer on a growing data team, helping scale our AWS-based data lakehouse and working primarily with industrial data sources and high-volume time-series data. No prior experience in the energy sector is required, we’ll support you in learning the domain.

##### Key Responsibilities

- Build and maintain scalable ETL/ELT pipelines for batch and real-time processing, including high-frequency time-series ingestion.

- Evolve the Data Lakehouse — optimizing storage, performance, cost, and data consistency.

- Manage orchestration workflows with complex dependencies and error handling.

- Deliver production-ready, analytics-optimized datasets, engaging directly with end users to understand how they consume data.

- Implement data governance, security controls, and audit policies across the AWS ecosystem.

- Build monitoring, alerting, and data quality testing for platform reliability.

##### Key Requirements

- Bachelor’s degree in Computer Science, Computer Engineering, or a closely related discipline.

- 3+ years of hands-on Data Engineering on AWS, with real exposure to modern data lakehouse architectures.

- English at B2 or above. Daily work with English-speaking teams and written documentation.

- Production experience with open table formats, preferably Apache Iceberg (table design, partitioning, schema evolution). Coming from Delta Lake or Hudi? We’ll support you in transitioning.

- Core AWS data services: Glue, Athena, Lambda, and S3.

- Designing and maintaining ETL/ELT pipelines for batch and streaming workloads.

- Python (PySpark / Python Shell) and advanced SQL (window functions, CTEs, execution plan tuning).

- Data modeling for analytical workloads in a lakehouse context — medallion architectures, incremental loads, deduplication, historical backfills.

- Infrastructure as Code: Terraform or CloudFormation.

Preferred Experience

Step Functions · Kinesis · Lake Formation · DynamoDB · custom ETL with boto3, pyiceberg, pyarrow · CI/CD for Glue or Lambda · time-series and IoT/telemetry data at scale
