Responsibilities
What You’ll Own
• Lakehouse Pipelines & Ingestion (35%)

Design and own batch ETL/ELT and CDC pipelines that bring sensor and operational data into the lakehouse, orchestrated in Dagster
Build for reliability: idempotent, incremental, backfill-safe pipelines with sane retry and failure handling, that still produce correct output when a worker is killed mid-run or a message is delivered twice
Onboard new client data sources: schema and tag mapping, time-series normalization, resampling, gap handling at scale
2. Modeling & Serving (25%)
Model raw data into well-structured, documented tables that downstream ML and analytics can trust
Build and maintain the datasets behind ML feature pipelines and the lakehouse layer powering self-serve analytics
Write performant Spark/PySpark and SQL; optimize partitioning, storage formats, and query cost
3. Data Quality & Reliability (10%)
Own data quality: validation, freshness/SLA monitoring, and observability so bad data is caught before it reaches consumers
Make the data layer debuggable: lineage, tests,



and alerting that tell you what broke and where
Reason about failure modes across the whole path (queue, worker, orchestrator, database, object store) and design so that a partial failure leaves the system in a state you can recover from
4. Relational & Operational Data (30%)
Contribute to the schema, indexing, and query performance of the relational database the product runs on
Design tables and constraints so that correctness is enforced at the database layer, and diagnose slow queries from their plans
Own retention and the boundary between the operational database and the lakehouse: what stays, what moves, and how it gets there

What Success Looks Like
First 30 days: Productive in the codebase and orchestration layer. First pipeline change merged.
First 90 days: Independently shipping and owning pipelines. Onboarded at least one current data source end-to-end.
First 6 months: Owning a lakehouse data domain, its ing
