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. \nRole Summary\nON.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.\nKey Responsibilities\nBuild and maintain scalable ETL/ELT pipelines for batch and real-time processing, including high-frequency time-series ingestion.\nEvolve the Data Lakehouse - optimizing storage, performance, cost, and data consistency.\nManage orchestration workflows with complex dependencies and error handling.\nDeliver production-ready, analytics-optimized datasets, engaging directly with end users to understand how they consume data.\nImplement data governance, security controls, and audit policies across the AWS ecosystem.\nBuild monitoring, alerting, and data quality testing for platform reliability.\nKey Requirements\nBachelor’s degree in Computer Science, Computer Engineering, or a closely related discipline.\n3+ years of hands-on Data Engineering on AWS, with real exposure to modern data lakehouse architectures.\nEnglish at B2 or above. Daily work with English-speaking teams and written documentation.\nProduction 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.\nCore AWS data services: Glue, Athena, Lambda, and S3.\nDesigning and maintaining ETL/ELT pipelines for batch and streaming workloads.\n Python (PySpark / Python Shell) and advanced SQL (window functions, CTEs, execution plan tuning).\nData modeling for analytical workloads in a lakehouse context - medallion architectures, incremental loads, deduplication, historical backfills.\nInfrastructure as Code: Terraform or CloudFormation.\nPreferred Experience\nStep 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\nFor US-based roles - What you’ll get:\nCompetitive salary + annual performance-based bonus eligibility\nMedical, dental, and vision insurance\n401(k) with company match\nPaid time off and company holidays \nFor Mexico-based roles - What you’ll get:\nCompetitive salary + annual performance bonus eligibility\nChristmas Bonus (Aguinaldo): 30 days\nMajor medical expenses and life insurance\nPaid time off and holidays (per local policy)\nFor all roles:\nProfessional development and growth opportunities\nOpportunity to grow with a mission-driven team shaping the future of clean energy\nEqual Opportunity: ON.energy is committed to equal employment opportunity and to maintaining a work environment free of harassment, discrimination, or retaliation.\nBenefits vary by role and location and are subject to change.\nAgency Notice: ON.energy does not accept unsolicited resumes from staffing agencies, search firms, or third-party recruiters.
