Alchemy - Senior Data Engineer
Requirements
• Experience independently building and operating production data pipelines and the infrastructure around them. • Strong SQL and Python skills, including testing, debugging, and maintainable software design. • Experience with Snowflake or a comparable warehouse, including performance tuning and access management. • Experience with workflow orchestration and transformation tools such as Airflow and dbt, or equivalent systems. • Understanding of data modeling, incremental processing, schema evolution, and data-quality testing. • The ability to trace a data discrepancy from a downstream report back to its source, explain the cause, and fix it. • Good judgment about stakeholder needs: turn recurring requests into reusable datasets or tooling, and make trade-offs clear. • Kafka, database replication, or change-data-capture systems. • Apache Iceberg, Spark, Trino, or other lakehouse and query technologies. • Infrastructure as code, data observability, lineage, and disaster recovery. • Usage metering, billing and revenue data, or semantic layers for self-service analytics. • What Success Looks Like • Within three months: • You own a production pipeline and have shipped an improvement to its freshness, reliability, or operating cost. • Downstream users can see whether its data is current, recovery procedures have been tested, and a recurring manual request has become a reusable dataset or tool.
Responsibilities
• Build batch and streaming pipelines that connect operational databases, product events, billing systems, and external sources to the internal data platform. • Make ingestion recoverable through change-data capture, schema-change handling, idempotent processing, and safe backfills. • Operate and improve Snowflake, including access controls, workload management, query performance, and compute and storage costs. • Improve orchestration and deployment workflows so engineers can test, ship, and debug pipelines safely. • Build data-quality checks that detect stale, missing, duplicated, or inconsistent records before they reach downstream consumers. • Work with analytics partners on shared data models, source definitions, and documentation. Make dataset ownership and upstream dependencies clear. • Reduce recurring manual work and build reusable tools for self-service data access. • Participate in production support and incident response for pipelines and the data platform. Restore data flow, reconcile affected datasets, and fix the causes of recurring failures.
