The Role You own the data substrate and the batch runtime of a product we are building from scratch. This is a data-specialist seat, not a general backend seat. Routine application development is guided in weekly reviews; what cannot be substituted is your depth in data modeling, set-based computation, and pipeline correctness. You will work self-directed, writing your own specs and decisions, with your tests and documentation carrying the quality bar between reviews. Stack: Python, PostgreSQL, Django, server-rendered frontend (htmx). What You Will Own Core Responsibilities / Engineering Focus Deep third-party data ingestion Build reliable ingestion pipelines for external data sources Account for silently dropped webhooks through reconciliation with source-of-truth totals Large-scale batch computation Use set-based SQL for processing large datasets Ensure jobs complete within fixed nightly processing windows Multi-tenant reliability Maintain strict tenant isolation Ensure one tenant’s bad data does not impact another tenant’s processing Backfill & replay capabilities Design systems to support backfills and replays as standard capabilities Avoid relying on one-off emergency scripts Append-only & auditable data Maintain immutable, auditable records Ensure every automated decision can be reconstructed and traced Resilient vendor API integrations Build for failures and unreliable external systems Implement retries, circuit breakers and reconciliation mechanisms Operational reliability Build strong alerting and monitoring Handle database partitioning effectively Design and maintain idempotent jobs

Queues backing up Webhooks silently dropping Data loss or inconsistencies Reconciliation catching issues that went unnoticed
