About this role
About this Role:
At BlackRock, technology is the foundation of our business. As a Data Engineer, you’ll build resilient systems that power our global post-trade operations. You’ll design and deliver enterprise-scale software with a focus on reliability, performance, and clean engineering practices.
This role is ideal for engineers who like to innovate and solve complex challenges while fostering a culture of excellence and continuous improvement.
About Post Trade Accounting (PTA):
- A major strategic area within Aladdin and one of BlackRock’s largest engineering investments.
- Responsible for the systems that ensure accurate, scalable, and efficient accounting across global operations.
- Expanding into data analytics and pipeline initiatives using Snowflake, Redis, and Kafka to manage high-volume, real-time data.
- Collaborates closely with Product, Operations, and other Engineering teams to deliver business-critical capabilities.
- Agile and collaborative environment that values technical depth, quality, and innovation.
Key Responsibilities:
- Partner with domain experts, product, and engineering teams to design canonical data models (conceptual → logical → physical) that power trusted reporting, analytics, and downstream integrations.
- Build and evolve analytics-ready datasets in Snowflake (curated layers / data marts), including clear metric definitions (grain, dimensions, measures) that enable consistent enterprise reporting.
- Design and develop reliable ELT/ETL pipelines across Snowflake and SQL Server to support both scheduled batch loads and low-latency ingestion where needed.
- Implement robust pipeline patterns such as incremental processing, idempotency (replay-safe loads), deduplication, and backfill/reprocessing strategies.
- Establish and enforce data quality and observability practices (freshness, completeness, accuracy checks; alerting; runbooks; SLAs) to keep data products production-grade.
- Optimize analytical performance and cost by applying Snowflake best practices (clustering/partition strategies, materializations, query optimization) and SQL Server performance tuning where appropriate.
- Publish curated data to downstream systems and serving layers when needed (e.g., search indices like Elasticsearch and operational stores like Cosmos DB) with clear contracts and monitoring.
- Drive best practices for documentation, lineage, schema evolution, and secure handling of sensitive data (PII) in collaboration with platform and governance partners.
Qualifications / Competencies:
- B.S./M.S. in Computer Science, Engineering, or related discipline (or equivalent practical experience).
- 8+ years of experience building production data systems, with demonstrated ownership of data modeling and data pipeline engineering.
- Strong SQL skills (advanced querying, query plans, performance tuning) with hands-on experience in Snowflake and/or Microsoft SQL Server.
- Proven experience with data modeling for analytics (dimensional modeling / star schemas, conformed dimensions, slowly changing dimensions) and translating business concepts into robust schemas.
- Hands-on experience designing and implementing ELT/ETL pipelines, including batch and near-real-time patterns.
- Proficiency in at least one general-purpose language used for data engineering (e.g., Python, Java, or Scala) for automation, orchestration, and integrations.
- Working knowledge of modern data engineering practices: testing for transformations, CI/CD, environment promotion, and operational monitoring.
- Strong communication skills and comfort collaborating with domain experts to turn ambiguity into clear, implementable data products.
Nice to Have:
- Experience with transformation and modeling frameworks (e.g., dbt) and/or a semantic/metrics layer approach.
- Exposure to orchestration tools (e.g., Airflow, Dagster, Prefect) and patterns for dependency management and backfills.
- Streaming and event-driven data experience (e.g., Kafka, CDC patterns) and understanding of late-arriving data, watermarking, and replay.
- Experience integrating downstream serving/search systems (e.g., Elasticsearch) and operational datastores (e.g., Cosmos DB).
- Familiarity with data governance and observability tooling (catalog/lineage, OpenLineage-style concepts, data quality frameworks).
- Cloud-native exposure (Docker/Kubernetes, AWS/Azure/GCP) and infrastructure-as-code (Terraform).
- Interest in financial systems, accounting, or investment technology.
