Software Engineer - DLT PhD Candidates (2024 graduates)

P-187

Databricks is radically simplifying the entire data lifecycle, from ingestion to generative AI and everything in-between. We’re doing it cross-cloud with a unified platform, serving over 10k customers, processing exabytes of data/day on 15+ million VMs, and growing exponentially.

The Delta Live Tables team (DLT) is looking for recent PhD graduates. Delta Live Tables (DLT) makes it easy to build and manage reliable batch and streaming data pipelines that deliver high-quality data on the Databricks Lakehouse Platform. DLT helps data engineering teams simplify ETL (extract-transform-load) development and management with declarative pipeline development, automatic data testing, and deep visibility for monitoring and recovery. DLT optimizes pipeline execution by logical optimization through query transformations, and physical optimization such as instance type selection and vertical/horizontal autoscaling.

Moreover, as part of DLT, we have a new catalyst optimization layer, enzyme, designed specifically to speed up the ETL process and make declarative ETL computation possible by incrementally computing and materializing the intermediate results. Enzyme can create and keep up-to-date a materialization of the results of a given query stored in a Delta table. Enzyme does this by using a cost model to choose between a variety of techniques that borrow from traditional literature on the maintenance of materialized views, delta-to-delta streaming, and manual ETL patterns commonly used by our customers.

As a part of the DLT team, there are opportunities to design and implement in many areas that leapfrog existing systems:

• Query compilation and optimization
• Distributed query execution and scheduling
• Vectorized engine execution
• Resource Management
• Transaction coordination
• Efficient storage structures (encoding, indexes)
• Automatic physical data optimization

What We Look For:

• PhD in databases or systems
• Knowledge of database systems, storage systems, distributed systems, and performance optimization
• Motivated by delivering customer value and influence
