They are seeking a Senior Data Engineer to contribute to data modeling, reporting, and building AI-ready data infrastructure while ensuring platform reliability and collaborating with cross-functional teams.

Responsibilities

• Contribute to the modeled data and pipelines behind customer-facing reports on consumption, cost, and rate trends
• Ingestion, semantic models, storage solutions, and retrieval (SQL, RAG, vector, or graph-based)
• Contribute robust facts and dimensions that power analysis us and for our customers
• Own testing, lineage, freshness monitoring, and alerting so data issues are caught before a customer sees them
• Translate vague product and compliance questions into concrete models, working directly with engineers, analysts, and PMs

Skills

• 4+ years in data platform engineering. Bonus if you've been a primary builder on a platform from early stages
• Strong Python and SQL
• Hands-on DBT experience
• Dimensional modeling fluency. Star schemas, facts and dimensions
• Direct experience with our stack is a significant plus. In order of preference: Dagster (asset-based orchestration, sensors, partitions) — strongly preferred over Airflow experience alone, DuckDB or MotherDuck — even side-project or exploratory use
• Comfort analyzing data directly
• Experience with AI/LLM-adjacent data work: RAG pipelines, embedding stores, evaluation frameworks (e.g. LangSmith or PydanticAI), or knowledge-graph approaches for structured retrieval
• Azure experience
• Utility, energy, PropTech, or billing domain background
• Experience building data products for external customers (not just internal BI)
