The Senior Data Engineer will join the newly formed Datacraft team at Bloomreach, focusing on building a next-generation data platform that powers internal data warehouses, analytics dashboards, and the Loomi Analytics Agent. This role directly impacts how enterprise customers access, understand, and activate their data across Snowflake, BigQuery, Databricks, and other platforms.
What You'll Do
- Build the DWH data platform — Design data pipelines (Kafka → GCS → Iceberg → DWH) following medallion architecture
- Own data models and ETL mutations for ID resolution and consent semantics
- Maintain orchestration (Airflow / Cloud Composer) and monitoring
- Shape Loomi Analytics Agent's data layer — Implement evaluation harnesses and analytics skills
- Fine-tune system prompts and traces
- Build MCPs and data interfaces for the agentic platform
- Ensure data access patterns are reliable and debuggable
- Co-build dashboards & analytics stack — Design canonical metrics and models on DWH
- Support semantic layers and BI tools (Cube, Looker Studio)
- Ensure tight Loomi integration
What We're Looking For
- Solid data engineering background with strong SQL and data modeling skills (star/snowflake schemas, slowly changing dimensions, partitioning/clustering, etc.)
- Hands-on experience building production-grade data pipelines on GCP, ideally involving BigQuery, Apache Iceberg, Apache Spark on DataProc, and Airflow (Cloud Composer)
- Experience with orchestration and workflow tools — specifically Airflow / Cloud Composer — and comfort working with DAG-based systems for scheduled and event-driven jobs
- Familiarity with open table formats (Iceberg preferred, Delta Lake / Hudi acceptable) and how they interact with query engines and DWH platforms
- Strong programming skills in Python (preferred); Scala/Java/Go also relevant
- Good understanding of data quality, lineage, and observability (monitoring SLAs/SLOs, detecting missing/late loads, backfilling strategies)
- Ability to work across product and engineering teams, turning fuzzy problem statements into incremental, shippable slices
Nice to Have
- Experience with agentic platforms or AI-powered analytics (agent orchestration, LLM data access layers, evaluation harnesses)
- Background in marketing analytics, CDPs, or BI/semantic layers (Looker, dbt, Cube)
- Experience with Snowflake or Databricks alongside BigQuery
Technical Stack
Python, Go, SQL, Apache Kafka, BigQuery, Iceberg, GCS, Mongo, Redis, Spark, DataProc, Airflow, Snowflake, Databricks, GCP, Kubernetes, Terraform, LLM APIs, MCP, agent orchestration, Cube, Looker Studio, Grafana, Prometheus, PagerDuty, Sentry, OpenTelemetry, GitLab CI/CD, Cursor, Claude Code
