Job Description

Block’s Data Foundations group builds and maintains a data platform that enables customers to publish, aggregate and orchestrate low-latency data at scale from across Block’s distributed ecosystem.  Our job is to make it easy for data producers to integrate data into the platform and for data consumers to use it once it’s there. Our goal is to allow data users to spend less time on infrastructure so that they can spend more time delivering business value. 

Within that group, the Data Aggregation Platform team builds systems that aggregate data from all over the company together into shared data processing systems like Databricks and Block's Machine Learning Platform.  To accomplish this goal, we’re building a scalable streaming data ingestion system that enables publishers from all over the company to send their data into our systems, configure where it should go, and define transformations on top of it. At the same time, we’re building infrastructure on top of Databricks to enable Machine Learning Engineers and Analysts to start working with batch and streaming data with minimal setup. 

We sit in a unique spot as a platform team since we are able to work with data scientists, engineers, and product managers from across the organization. We learn directly from our customers and build software that improves their productivity and impact.

  4. Lead architectural and design discussions, ensuring our platform is performant, fault tolerant, and maintainable
  5. Mentor your teammates and assist engineers on other teams who integrate with our platform


  1. 5+ years of production software engineering experience
  2. A desire to solve our customer’s problems by iterating with them on requirements and solutions
  3. Experience working with stream processing technologies such as Kafka, PubSub, and Spark Structured Streaming
  4. Experience designing and building flexible large scale data processing systems, ideally with Spark
  5. Experience using AWS, particularly familiarity with: AWS IAM, standard AWS networking concepts (PrivateLink, VPC configuration), and DynamoDB. 
  6. Demonstrated technical initiative and leadership on previous projects, as well as a track record of mentoring junior engineers

Technologies we use and teach:

  • Java, Python
  • Spark (Databricks), Kafka (Confluent)
